In Shakespeare's Romeo and Juliet, what is meant by "cold fire," "wolfish lamb," and "loving hate"?

In Act 1, Scene 1, Romeo uses contradictory phrases like these ("loving hate," "cold fire," "sick health" and so on) as he's talking in an angry, frustrated way about two things: first, how sad he is that Rosaline doesn't love him back, and second, how frustrated he is that the two families seem to keep fighting with each other for apparently no other reason than that they enjoy it.


Romeo also says, "Misshapen chaos of well-seeming forms!" He means that all these beautiful things, like love, get twisted and warped into chaotic situations. So by saying something like "loving hate," Romeo is pointing out the weird dual nature of the feud between his family and the Capulets: they hate each other, but they love to hate each other, and they love to fight. He sees a similarity between that situation and his own personal romantic failure. Though Romeo loves Rosaline, she's not interested in him at all--so to Romeo, that situation is like "cold fire," meaning he's practically burning with passion for Rosaline, yet she's just cold to him in return.


As for "wolfish lamb," although Romeo doesn't say anything like that in the speech I just mentioned, Juliet does call Romeo a "wolvish-ravening lamb" when she finds out in Act 3, Scene 2 that Romeo has killed her cousin, Tybalt. Juliet means that Romeo is a "wolfish lamb" in the sense that he seems gentle and sweet like a lamb and yet he hunts and kills others like a wolf does. Her oxymoron describes her intense frustration with her feelings for Romeo at that moment; she both loves and hates him.


Are all these oxymorons (or contradictory statements) profound and deep, or are they the silly ramblings of frustrated teenagers? The answer is a matter of interpretation!

How will the election in all five states (note they all are swing states) affect the outcome of the 2016 Presidential election?

There are actually more than five swing states. Some people would say there are eleven swing states. However, I can still guide you with your question.


The swing states are critical in this election. Because it is known that certain states will definitely vote Republican or Democratic, the candidates must win enough of the swing states to get to the 270 electoral votes needed to win the election. It is these swing states that will decide if Hillary Clinton or Donald Trump will win the election. As a result, the candidates and their supporters will spend a lot of time and resources in these states. There isn’t much of a reason to spend time in a state that will almost certainly vote either for the Republican or for the Democratic candidate.


As a result, expect the candidates to spend a lot of time in Ohio, Pennsylvania, Florida, North Carolina, Virginia, Colorado, New Hampshire, Michigan, Wisconsin, Iowa, and Nevada. The candidate that wins most of these states will most likely become the next President of the United States.

What one of the four big ideas in biology does Stiff: The Curious Lives of Human Cadavers address?

Well, I assume you mean the big ideas of an AP Biology course; the answer I would choose is Systems or Energy, although the case could be made for all of them. 


I say systems because death involves the entire body, top to bottom. Most of the chapters were concerned with how people use bodies. The first few chapters were about dissection and organ harvesting, like how systems of the body are separated at death for use in testing and research. Chapter three was about how the systems decompose after death; little had anything to do with the other topics of information or evolution. Medicinal uses of body parts and forensic research all seemed to fit the topic of systems.


I would say energy because the topic is death itself. The research on the mass of the soul and literal soul-searching was very concerned with how energy is stored in the body. In the second to last chapter, Roach considers using corpses as fertilizers, composts, and lamp fuel as an alternative to traditional fuels, and even before that discuses cannibalism throughout the world.

What is the relationship of commerce with business?

The relationship between commerce and business is that business activity is carried on within the framework of commerce. Commerce encompasses all aspects of large-scale buying and selling activities carried on between nations, between or within states, and between or within industries, while business encompasses individual entities' activities related to buying and selling for company profit.

Commerce might be called the environment within which various business enterprises are carried out. Business is individual enterprises engaged in the full range of buying and selling activities; business is collectively one aspect of commerce.


Commerce describes the interchange of goods, services, and commodities between different nations and the interchange of goods, services, and commodities within the boundaries of different countries and the interchange of goods, services, and commodities between or within the boundaries of different states. Commerce encompasses all industries and branches of interchange on a macroeconomics level.

Business describes individual entities' participation in all aspects of the activities of buying and selling on a microeconomics level. Business encompasses buying and selling but also further encompasses activities such as investing, procuring, accounting, and financial reporting. Business operates along specialized lines and within specific industries within the large-scale compass of commerce.

Why is Sal in Ohio at the beginning of Walk Two Moons by Sharon Creech?

Sal and her father were from Bybanks, Kentucky, originally. After Sal’s mother left and it is determined that she is not coming back, Sal’s father moved himself and Sal to Euclid, Ohio. Sal resents this move, wanting to stay on their rural farm in Bybanks. The reason for the move is revealed to be Sal’s father's desire to be near Margaret Cadaver, their new next-door neighbor. Sal rejects any kind of friendship that Mrs. Cadaver displays toward her, and willingly joins in Phoebe’s idea that Mrs. Cadaver is a murderer. When Sal spends time with the Winterbottoms, Sal’s father usually goes over to Mrs. Cadaver’s house. Many times Sal’s father tries to explain Mrs. Cadaver’s connection to the family, but Sal refuses to hear it. She resents the fact that Mrs. Cadaver is there and her mother is not.  In the end, Sal learns the connection between Mrs. Cadaver and Sal’s mother and overcomes her resentment.

Why do people develop "crushes" and how long do they last?

"Crush" is a colloquial or slang term for having affectionate, romantic, or desirous feelings for someone. The term is often used when talking about the affection young people feel for another person. Unfortunately, crushes may be unrequited-- that is, only one person has feelings for the other. 


People develop crushes for a variety of reasons, but all crushes have a human need in common. Humans are social creatures and we thrive in relationships. These relationships may be parental/familial, work relationships, or even friendships. As we age and our bodies develop, our hormones start signalling that it might be time to find a mate. Most humans desire a long-term, romantic relationship with a partner. While our evolutionary drive for partnership is to mate, the best matches are between people who find people emotionally and mentally attractive in addition to any physical attraction. When puberty begins and hormonal changes start signalling and interest in mating, we often begin to feel this emotional and mental attraction to other people. Of course, crushes may involve physical attraction, but this isn't always necessary.


In short, we develop crushes because our bodies and brains have evolved to want a romantic partner in life.


Crushes develop from and are sustained by positive events. For example, if there's someone you have a crush on, think about what things happened to make you like them. Are they physically attractive? Do you have a lot in common? Are they funny, or kind, or responsible? The crush may last as long as you know and spend time around this person. If you stopped spending time together, the feelings you have might fade. Alternately, the crush might fade away if you see this person doing something you don't find attractive.


Having a crush on someone can be pretty frustrating, especially if you don't know how the other person feels. You could have a friend speak to this person for you and find out if they have a crush on you, too. If your parents are okay with it and willing to accompany you, you might ask this person to go see a movie or have lunch. If you really just want this crush to be over with, try throwing yourself into your hobbies as a distraction.

In what ways could Simon be considered a hero in the novel Lord of the Flies? In what ways would Simon not be considered a hero?


Simon could be considered a hero throughout the novel because he is a selfless character who helps others and is the only boy who understands the true identity of the "beast." Unlike the majority of the boys on the island, Simon goes out of his way to help the littluns and continually encourages Ralph. Simon is quick to lend Piggy a hand and even volunteers to travel back through the forest alone to tell Piggy where the group is located. Simon is the only character who does not succumb to savagery at some point in the story, and he is the only boy to discover that the "beast" is actually a dead paratrooper. His bravery, insight, and caring nature would qualify him as a hero.


One could not label Simon as a hero because he was never able to express himself during the assemblies and does not spread the message to the other boys about the true identity of the "beast." Simon is killed before he gets a chance to relay his message that the "beast" is man's inherent wickedness. Simon's inability to share his message results in the further decay of civilization which eventually leads to Piggy's death.

Are guinea pigs a source of nutrition?

While it may be considered taboo in many cultures, guinea pigs are consumed in some parts of the world and do offer fairly substantial nutrition. Guinea pigs are eaten throughout South America, where they are called cuy, as well as in some Sub-Saharan African nations. Several American television programs focusing on world cuisines have featured chefs who visit parts of South America to eat cuy as a sort of dare-devil display. Most people in the western world are familiar with guinea pigs as house-pets and therefore reluctant or even disgusted by the idea of eating these small mammals.


It is difficult to find accurate nutritional data on cuy meat, as there isn't a lot of rigorous nutritional study in nations where they are commonly eaten. This webpage states guinea pig meat is about 19-20% protein, which is more then beef! This webpage also notes that cuy meat is only about 8% fat, which is quite lean compared with other animals raised for meat. Unfortunately, there are no web resources which share the more intricate details of cuy nutrition, such as the vitamin and mineral content of the meat. All around, cuy can be considered a good source of protein and many people around the world hope they will become a more widely raised, sustainable source of meat.

What are the similarities between Passover and the Eucharist?

Great question! Actually, the Christian (primarily Catholic) tradition of celebrating the Eucharist developed out of Passover traditions. Jesus of Nazareth was raised in a Jewish society and even grew up to be a Rabbi. As such, he celebrated the holiday of Passover. This holiday is celebrated in remembrance of when God freed the Jewish people from enslavement in Egypt. Moses had demanded freedom for the Jewish people from Pharaoh many times, but he would not let them go. God sent swarms of frogs and sickness on the Egyptian people as a warning, but still Pharaoh would not free the Jewish slaves. The final plague God sent upon the Egyptians was that all of the first-born children would die. However, the Jewish people and their children were protected--God "passed over" their homes. It was after this plague that Moses led the Jewish people out of Egypt and to their freedom.


Jesus of Nazareth would have celebrated this holiday in springtime in remembrance of his heritage as well as part of his duties as a Rabbi. While Passover traditions vary from place to place, and even from family to family, all Passover celebrations involve a meal. Before his crucifixion, Jesus gathered with his disciples to share a Passover meal. Jesus knew that in the coming days, he would be crucified and die. It was at this meal that he told his disciples to eat some bread and drink some wine in remembrance of him. He said that his followers should remember his life as well as his message to love one another (even your enemies), and to accompany this remembrance by eating some bread and wine. One of the early doctrines of the Christian faith was that people continued to celebrate the life of Jesus by getting together to share some bread and wine.


Today, the Eucharist (from the Greek for "giving thanks") is celebrated regularly by Catholics and some other Christian denominations. The Eastern Orthodox Church continues to use bread for their celebration of the Eucharist, but most congregations who celebrate this Sacrament use a little wafer made of wheat flour. The Eucharist is considered a symbol for and manifestation of the sacrifice Jesus of Nazareth made when he was crucified. As opposed to Jesus' celebrations of the Passover meal, the Eucharist may be celebrated daily (though most do it weekly) in remembrance of Jesus and his message. 


Both the Passover meal and the modern Eucharist are traditions focusing on God's covenants with man--the promises God and man made to one another about their responsibilities in their relationship. The Passover celebration has to do with the founding of Judaism and God's "Ten Commandments" given through Moses. In the Christian tradition, when people failed to live up to God's original commandments, Jesus was sent to establish a new covenant. He led by example and asked others to fulfill their duty to God by simply loving one another. Celebrating Passover and the Eucharist are both ways of reminding oneself and others of the duties and relationship between God and man.

When will the three witches meet again?

The first Weird Sister asks this very question to open the play.  The second sister replies that they will meet again after the battles in which Macbeth and Banquo are fighting have concluded, as she says, "When the hurly-burly's done" (1.1.3).  The third sister replies that this will be at sunset.  The first sister asks where they will meet, and the second says that they will meet "Upon the heath" (1.1.7).  A heath is a type of grassy, shrubby field that is often found in Scotland.  It is upon on this field, then, that the Weird Sisters plan to meet with Macbeth, and this is the next time that they will all be together.  


When they do meet again, in Act, scene 3, they spend some time discussing what they've been up to since they last saw one another: general mischief making, some malicious killing of animals, and constructing of plans to exact revenge on the husband of a woman who would not share her nuts.  Then the sisters seem to cast a little "charm," dancing around and chanting in a circle until the moment when Macbeth and Banquo arrive (1.3.38).  

What was the outcome of the impeachment trial with President Johnson?

Andrew Johnson became president after the assassination of Abraham Lincoln.  While Johnson was a Republican who had served as the Vice President of the Union, he was a Southern sympathizer.  As President, he disagree with many aspects of Reconstruction.  


Johnson violated the Tenure of Office Act by dismissing his Secretary of War.  This angered many people, especially those who already opposed Johnson's Southern sympathy.  The House of Representatives impeached Johnson over the Tenure of Office Act incident, and his case was sent to the Senate.  In the Senate, they tried Johnson over a period of nearly three months.  In an attempt to appeal to the senators trying him, Johnson promised that he would stop opposing the Reconstruction Acts.  Despite these promised changes, he was saved from conviction by the Senate by a single vote.

What is the largest estuary in the world?

To understand what the largest estuary in the world is, one must first understand what an estuary is. An estuary is generally defined as the area where freshwater from a river or stream and salt water from the ocean meet. The type of water in this area is known as brackish water. Typically, estuaries can be grouped into one of four different categories based on how they were formed. These categories include costal plain estuaries, tectonic estuaries, bar-built estuaries, and fjord estuaries. In terms of size, the largest estuary located entirely in the United States is the Chesapeake Bay, which encompasses over 64,000 miles throughout Pennsylvania, Maryland, New York, Virginia, Delaware, and Washington DC. Despite the massive size of the Chesapeake Bay, most scientists agree that the St. Lawrence River, which connects the Great Lakes to the Atlantic Ocean, is considered the world’s largest estuary.

Where did the earliest forms of life come from?

The Descent of Man by Charles Darwin one a landmark work in what became the science of evolutionary biology. In this work, Darwin noticed the correspondences among various species. He also was aware of how selective breeding worked. Farmers had for millennia been breeding animals for desired traits to develop horses that ran faster or could haul heavier weights, dogs that were efficient hunting partners, or food animals that were hardy, placid, and able to efficiently convert fodder to meat. By combining these types of knowledge with his encounters with primitive peoples, he argued that humans, and in fact, all animals, were the product of evolution.


The key mechanisms he used to explain evolution were random mutation and natural selection. Random mutation is something we can all observe when we see, for example, polydactyl cats or other such minor variations in species. Natural selection ensures that if a mutation helps the species survive, it will propagate through the species, eventually creating a distinct subspecies or even a new species. Thus Darwin argues that humans evolved from non-human primates through precisely this mechanism of random mutation and natural selection.


The very earliest forms of life, of course, were not human but were unicellular organisms that formed nearly four billion years ago, probably from chemical reactions.

What would Malcolm X have thought about the United States annexing Texas?

Because the annexation of Texas occurred in a different time period than when Malcolm X lived, we have to speculate on what his thoughts might have been. By looking at some of the things Malcolm X believed, we can speculate what he might have thought.


Malcolm X would have been against slavery. Since he was fighting racial segregation in the United States in the 1950s and 1960s, it is fair to conclude he would have been against slavery. Since Texas was going to be a slave state, it is reasonable to conclude Malcolm X would be against the annexation of Texas. Malcolm X wanted African-Americans to be treated equally to white people. That was not going to happen in Texas with the existence of slavery.


Malcolm X would probably have been a very strong voice against the annexation of Texas as a state.

Iodine-125 (125I) is used to treat, among other things, brain tumors and prostate cancer. It decays by gamma decay with a half-life of 54.90 days....

Half life is the amount of time after which only 50% of the original quantity remains. For example, the half life of Iodine-125 is 54.9 days. This means that after 54.9 days, half of the original implant value would have decayed. Similarly, after 2 half lives or 109.8 days (= 2 x 54.9 days), only 25% of the original content would be left. 


The initial decay rate or activity (A0) = 532 `mu`Ci, time period = 389 days.


Decay constant, `lambda`  = 0.693/T, where T = half life = 54.9 days


Using `A = A_0 e^(-lambdat)`


Solving for a time duration, t = 389 days, we get A = 3.92 `mu`Ci


For 16.5% of the initial value, A = 16.5% of A0 = 0.165 A0


Substituting this into the equation, we get


`A/A_0 = e^(-lambdat) = 0.165`


substituting the value of decay constant, we get, t = 142.74 days.


Assuming there are 30 days in a month, it will take about 4.76 months for the activity to be 16.5% of the initial value.


Hope this helps.

What custom does Hamlet mean when he says "But to my mind, though I am native here and to the manner born, it is a custom more honour'd in the...

Hamlet is referring to the custom of heavy drinking. King Claudius is not the only heavy drinker, but he sets an example which others are expected to follow. Hamlet strongly disapproves of it, mainly because it gives the Danes a bad reputation in other nations. When Horatio asks, "Is it a custom?", this suggests that Horatio is something of a stranger to the Danish court. He must live in some other part of Denmark. When Hamlet first meets him in Act 1, Scene 2, he says:



We'll teach you to drink deep ere you depart.



Horatio has been a fellow student at Wittenberg. Hamlet is wittily implying that Elsinore is an intellectual and cultural wasteland which has nothing to teach but heavy drinking. Hamlet is alluding to King Claudius, who is the heaviest drinker of them all. Claudius is seen drinking throughout the play, and he is drinking at the end when he accidentally causes Gertrude to kill herself with a poisoned drink intended for Hamlet and is then killed with the same goblet after Hamlet has stabbed him with the poisoned foil. The king's heavy drinking is probably meant to be a symptom of his guilty conscience. He is eaten up with guilt and fear of eternal damnation for having murdered his own brother. In Act 3, Scene 3, when Hamlet overhears him trying to pray, Claudius reveals that he is not the happy, carefree man he pretends to be.



O, my offence is rank, it smells to heaven;
It hath the primal eldest curse upon't,
A brother's murder! Pray can I not,
Though inclination be as sharp as will;
My stronger guilt defeats my strong intent....



Hamlet hates and despises everything about his uncle. He is especially annoyed by his uncle's drinking because he considers it disgraceful for a monarch to behave in public the way Claudius behaves. Hamlet tells Horatio that heavy drinking is indeed a custom,



But to my mind, though I am native here
And to the manner born, it is a custom
More honour'd in the breach than the observance.
This heavy-headed revel, east and west,
Makes us traduced and tax'd of other nations;
They clepe us drunkards and with swinish phrase
Soil our addition; and indeed it takes
From our achievements, though perform'd at height,
The pith and marrow of our attribute.



By "more honour'd in the breach than the observance," Hamlet obviously means that the custom of heavy drinking would be more honored by giving it up altogether. This is one way in which Hamlet shows a character superior to that of the King. Hamlet is the legitimate heir to the throne. Claudius is an unworthy usurper. Hamlet states his true opinion of Claudius to his mother in privacy in Act 3, Scene 4:



A murderer and a villain!
A slave that is not twentieth part the tithe
Of your precedent lord; a Vice of kings;
A cutpurse of the empire and the rule,
That from a shelf the precious diadem stole
And put it in his pocket!


In Call It Courage by Armstrong Sperry, do Kivi and Uri share boar meat?

The answer to this question can be found on p. 68 of Call It Courage.  There, the author at least implies that Uri will share in the meat of the boar, but he clearly states that Kivi does not eat the meat.


On p. 66, Mafatu kills the boar with the spear that he has made.  He cleans the pig and stuffs it on p. 67 and puts it into the underground oven that many Pacific island cultures use to cook things like pigs.  On p. 68, the author tells us about the actual feast.  He does not specifically tell us that Uri had any of the boar meat.  However, he does imply that Uri will.  He says that, as the boar cooked, “Uri leaped about, sniffing at the delicious odors, barking his delight.  Pork! … how good it would taste!”  From this, it is clear that Mafatu is going to give Uri some of the meat even though, later on the page, the author describes Mafatu eating but does not specifically describe him giving any food to Uri.


On the other hand, it is clear that Kivi, the albatross, will not eat any boar meat.  On p. 68, he says “Kivi, no meat eater, looked on calmly…”  He goes on to say that Kivi would “join in the feast” by eating a coconut that Mafatu would split open for him.  From these quotes, we can see that Uri almost certainly does eat the boar meat but that Kivi does not.

In Praying for Sheetrock by Melissa Fay Greene, what are some of the similarities and differences between Thurnell Alston and Sheriff Poppell?

Melissa Fay Greene’s Praying for Sheetrock: A Work of Nonfiction tells the story of McIntosh County, a small, isolated Georgia town, where, in the 1970s, the civil rights movement had bypassed entirely.  Despite the desegregation achievements that were sweeping across the nation in the 1970s, McIntosh County was heavily stratified by race, with the white sheriff presiding over all social, ethical, and legal affairs.  The story is essentially about two men:  Thurnell Alston, a black man who took on the white hierarchy of McIntosh County, and Tom Poppell, the white sheriff who ruled over the community. 


First and foremost, both men are strong, charismatic characters who are steadfast in their beliefs and use their power to influence those around them.  Thurnell Alston was a disabled boilermaker, but he was not afraid to voice his opinions or stand up for what he thought to be right.  He states, “There’s a lot of people have been intimidated in McIntosh, but there was no fear of things for me.  I would tell it the way I see it.  Regardless of who they are, I mean they could kill me for it, because I’m going to say it anyway” (Greene 54).   Similarly, the narrator describes Sheriff Poppell as a resolute and affecting man: “In modern times Sheriff Poppell was the neighborhood headman who exerted his will and shaped the county, and the people acquiesced as people do when they are not, themselves, hungry for power and when they are permitted to make a living far from the rumpus” (Greene 13).  Sheriff Poppell uses his uncontested control to have his way in the community, and, much like Alston, Poppell rises up from a body of people who are afraid to voice their opinions or simply do not care to challenge the existing status quo. 


Another similarity between Alston and Poppell is the fact that both men become involved in criminal activity despite their political standings.  From the beginning, Poppell is introduced as a corrupt official who blatantly denies equal rights to African Americans and pulls the cars of black people over, claiming it to be a routine search, but instead stealing their money and giving it to his officers.   Poppell also loots crashed or broken-down trucks unfortunate enough to cross his county line: “If the truck drivers had realized their trucks had crashed in McIntosh County, Georgia (431 miles of swamp, marsh, and forest: population 7,000) they would have known—that it was nearing time for a little redistribution of wealth” (Greene 3).  Yet, while Poppell enters the story as a known corrupted official, Alston’s corruption arrives later in the story when he becomes accused of drug trafficking: “Thurnell Alston was acquitted on the two charges alleging that he possessed, with intent to distribute, cocaine.  But he was convicted of conspiring to possess, with intent to distribute, cocaine; and two counts of using a telephone to facilitate a deal” (Green 321).  While Alston repeatedly denies the charges, he is sentenced to six-and-a-half years.  This similarity highlights how political standings can facilitate corruption. 


While both men appear powerful and unyielding at the surface, they do possess sympathy and compassion.  For example, Poppell looks the other way when poor black families pillage a wrecked semi-truck for shoes: “All day long under a sky like white coals the High Sheriff stood spread-legged on the highway, directing traffic; the road crews swept and shoveled; and hundreds of local families quietly harvest shoes” (Green 4).  Similarly, Greene makes it a point to devote a considerable portion of the story to Alston’s life as a father to develop his compassionate and loving side.  She states, “Four sons were born to her and Thurnell: Thun, Anthony, LeVan, and Keith; and four foster children were taken in by them.  Chickens in the backyard, dogs all around, mother-in-law and sisters-in-law and brothers and aunts in cabins and trailers in the pine woods about the house” (Green 48).  This description characterizes Alston as a caring, family man, and it is important because it arrives in conjunction with his drug conspiracy accusations, thus presenting him as a complex character, much like Sheriff Poppell.


There are several differences between Thurnell Alston and Sheriff Poppell.  First, both men are fighting on opposite sides: Thurnell Alston is advocating race equality while Poppell desperately clings to the status quo of white hierarchy.  Second, Sheriff Poppell is deeply rooted in historical precedent—he inherited his post from his father and rules the community “much as they had since emancipation” (Greene 23).  On the other hand, Thurnell Alston is invested in change and progress:  “Thurnell had something to give the black county again, and the immediate future seemed full of novelty and progress” (Green 299).  Finally, Thurnell Alston lacks the oratory skills often associated with an effective leader, while Sheriff Poppell is described as charismatic and charming.  Alston talks with a stammer in a high-pitched voice, and “he rarely matched words to thought very happily.  In fact, in an inverse relationship, the more he desired to express something of deep importance to himself, the more tongue-tied he became” (Greene 53).  Conversely, Sheriff Poppell “had a lot of charisma . . . He would handle everything just as cool and brilliant, just country brilliances is all I know how to describe it” (Green 5).  The difference in the delivery of both men is important because it characterizes their methods for change.  Whereas Alston fights against tradition and tries to convince the community that change is needed, Poppell placates any concerns with smooth talking and eloquent speeches.

How does Pirsig introduce and develop the character of Phaedrus in Zen and the Art of Motorcycle Maintenance? Can you rely on the narrator to offer...

Pirsig introduces Phaedrus slowly and with great trepidation. The first mention of him is in the foreword, in a quote from Plato. "What is good, Phaedrus, and what is not good; need we ask anyone to tell us these things?" After this brief namedrop, Phaedrus isn't mentioned for almost sixteen pages, and even then he is called a ghost, caught in the corner of Pirsig's eye. This ghost haunts Pirsig, and reminds him of what he could become again. 


When Pirsig and Chris climb the mountain, for example, Pirsig decides against reaching the summit. He tells Chris he fears a rock-slide, and to some extent, he does. However, what he really fears is the possible return of Phaedrus; he sees his previous nights ramblings as warnings akin to the falling pebbles he hears, and rather than push his luck, he heads back. This powerful scene is a dramatic show of how Phaedrus is something to be feared and respected.


I believe Pirsig is a reliable narrator of his own insanity. He has memories of a man who is not him, and has full access to a lifetime of notes and writings. It could be said that he knows Phaedrus better than anyone else in the world. When he looks back on what Phaedrus wrote, the insanity is clear to him, and is the cause of his fears.


I believe Phaedrus was insane. He was committed in an asylum for almost two years, and delivered electroshock therapy. This is very strong evidence pointing to Phaedrus' insanity.

In Shakespeare's play Julius Caesar, how is Brutus' greatness also his weakness?

What distinguishes Brutus from the others is that he acts on noble intentions, but these also make him naïve. 


Unlike many of the other conspirators, Brutus has no ambition in the purest sense.  He involves himself in the conspiracy because he believes it is for the good of Rome.  As long as Caesar is in power, by Brutus’s thinking, Rome cannot remain a republic.  Caesar will make himself king. 


Brutus does not desire to be king.  He wants things to go back to the way they were in what he sees as the golden days of Rome.  He pictures an idealized Rome, where the senate and republic reign supreme.  To this end, he is willing to assassinate Caesar. 


When Brutus decides that Caesar has to die, he convinces himself with a flowery speech about Caesar’s death. 



It must be by his death: and for my part,
I know no personal cause to spurn at him,
But for the general. He would be crown'd:
How that might change his nature, there's the question.
It is the bright day that brings forth the adder;
And that craves wary walking. (Act 2, Scene 1) 



While it may be noble to want to kill Caesar only for the good of his country, Brutus’s desire to make the assassination honorable causes trouble for his group.  Noble and practical are not the same thing.  Brutus refuses to kill anyone other than Caesar, leaving Mark Antony free to wreak havoc.  He also insists that the killing be public in the capital at the senate meeting, which makes it more dangerous.  The group has to get Caesar to that spot on that day, and prevent anyone from interrupting them. 


Brutus even allows Mark Antony to speak after him at Caesar’s funeral.  This may be noble, but it is a huge mistake.  Antony turns the people against Brutus and the others, and they have to go on the run and on the offensive. 


After his death, Antony acknowledges that Brutus may have had good intentions. 



This was the noblest Roman of them all:
All the conspirators save only he
Did that they did in envy of great Caesar;
He only, in a general honest thought
And common good to all, made one of them.
His life was gentle, and the elements
So mix'd in him that Nature might stand up
And say to all the world 'This was a man!' (Act 5, Scene 5) 



Thus, Brutus’s greatest strength was also his greatest weakness.  He truly loved Rome, and he was not an ambitious person.  However, he also felt that he could control the forces that he was trying to direct, and make sure that everything fit his idealistic version of tyranticide.  He was in over his head, and continually failed to acknowledge how things were really going.

How did Great Britain's military control in India change after the Sepoy Rebellion ?

The biggest effect on British control of the colony, one which had major implications for the British military, was that control of India passed from the East India Company, a corporation chartered by the Crown that held state-like authority in India, to the British Crown itself. This resulted in regular British troops (as opposed to troops controlled by the East India Company) being permanently stationed in the colony. "Sepoys" were Indian soldiers that served the British, and the large-scale revolt that rocked the colony began as a mutiny by Indian soldiers. So another major reform was that the number of British troops relative to Indian soldiers was dramatically increased. British forts and arsenals were constructed around India as the military presence there became a permanent garrison. While the Rebellion resulted in some reforms, the main effect was this tightening of British control of its most important colonial possession.

Solve the system of differential equations with by using Laplace transforms.

Hello!


For this problem, we need some properties of Laplace transform. They are:


`f'(t) -gt sF(s)-f(0)`


(here `F(s)` is the Laplace transform of `f(t)` ).


`sin(t) -gt 1/(s^2+1),`  `cos(t) -gt s/(s^2+1),`


`sinh(t) -gt 1/(s^2-1),`  `cosh(t) -gt s/(s^2-1).`



From these properties we obtain


`sX(s)=Y(s)+1/(s^2+1),`  `sY(s)=X(s)+(2s)/(s^2+1).`


It is a linear system for `X` and `Y` (the Laplace transforms of `x` and `y` ).


Its solution is


`X(s)=(3s)/((s^2+1)(s^2-1)) = 3/2 (s/(s^2-1)-s/(s^2+1)),`


`Y(s)=(2s^2+1)/((s^2+1)(s^2-1)) = 1/2 (3/(s^2-1)+s/(s^2+1)).`



Inverting Laplace transform we see that


`x(t)=3/2 (cosh(t)-cos(t)),`  `y(t) = 1/2(3sinh(t)+sin(t)).`


This is the answer.

What is the significance of the title and how is it related to Daru's conflict?

In French, the title of this story is "L'hôte," and this word has two meanings when it is translated into English. Firstly, it means the 'guest' and relates directly to the Arab prisoner who is taken to Daru's school by Balducci and becomes his guest.


Secondly, the title of this story can also be translated as the 'host' and, in this instance, relates directly to Daru, who is forced to host the prisoner when Balducci arrives with him unexpectedly. It is this interpretation of the title which relates to Daru's conflict: he has no desire to host the prisoner and is disgusted by the crime the prisoner committed. Still, he refuses to hand him over to the police, as he explains to Balducci:



"Listen, Balducci," Daru said suddenly, "every bit of this disgusts me, and first of all your fellow here. But I won't hand him over. Fight, yes, if I have to. But not that."



It is only by letting the prisoner make his own choice (to flee or go to jail) that Daru is able to resolve this conflict.

What is Kit's opinion of each member of the Cruff family?

There were three members of the Cruff family. Kit first observed "a shabby, dour-looking man and wife" and their young daughter (The Witch of Blackbird Pond, Chapter 1). Kit thought that Goodman Cruff was a "cowed shadow of a husband" (Chapter 2). He was timid and hardly spoke a word, even when his wife treated their daughter cruelly. Kit realized that he did care for his daughter despite his apparent indifference. Goodwife Cruff was suspicious and Kit thought of her as a cold person. She treated Kit with contempt. Kit was sometimes frightened of Goodwife Cruff, who was frequently unkind to Prudence, her daughter. Kit thought that Goodwife Cruff was a gossip when she saw her with a small crowd of women in Wethersfield. She found her to be a serious woman and an overly strict mother.


Kit was very fond of Prudence Cruff, the young daughter. She found the child to be kind, intelligent, and pleasant to be around. Kit thought that Prudence was like



a young fawn that had wandered near the house one morning.  It had drawn nearer... quivering with eagerness at the food Mercy set out, yet tensed to spring at the slightest warning (Chapter 11).



Beyond Prudence's frail body and timid appearance, Kit discovered an eager child who wanted to learn and be loved. Kit came to treasure the time she spent teaching Prudence how to read.

What happened during Viola's interview with Olivia in Twelfth Night?

Olivia’s basic premise is that Orsino doesn’t really know her and has no reason to pursue her.  She tells Viola that she only got in because she was “saucy” at the gate and Olivia was curious.


Viola is able to get in the door by being stubborn.  Olivia is not seeing anyone, because she is in mourning for her father and brother.  Viola will not take “no” for an answer though, and Olivia wants to know more about this unusual young man at her gate.


Viola is pretending to be Cesario, a young man, and she is in the employ of Orsino.  Orsino is in love with Olivia, but she won’t see him, so he sends Cesario/Viola.  Viola’s cleverness gets her into the house.  However, then she has to match wits with Olivia.


Viola tries to start the speech she has prepared, based on Orsino’s script, but she has trouble at first figuring out which lady is Olivia, and then Olivia is veiled.  Viola asks her to show her face.



OLIVIA


Have you any commission from your lord to negotiate
with my face? You are now out of your text: but
we will draw the curtain and show you the picture.
Look you, sir, such a one I was this present: is't
not well done? (Act 1, Scene 5)



The conversation continues along this vein.  When Viola tells her she is beautiful and should not be keeping herself from the world, Olivia says that she has no problem with her beauty, and will “give out divers schedules” of it.  Viola accuses her of being proud.  Olivia explains that Orsino can’t really love her without knowing her.



OLIVIA


Your lord does know my mind; I cannot love him:
Yet I suppose him virtuous, know him noble,
Of great estate, of fresh and stainless youth;
In voices well divulged, free, learn'd and valiant;
And in dimension and the shape of nature
A gracious person: but yet I cannot love him;
He might have took his answer long ago. (Act 1, Scene 5) 



In the end, of course, Olivia falls in love with Cesario instead of Orsino.  She enjoys the matching of wits.  She surprises even herself by falling for him.  Viola doesn’t realize this until Malvolio brings her the ring, a ploy to get Cesario to come back.  Viola then realizes that Olivia loves her as Cesario, and she feels sorry for her, even though she loves Orsino.

Describe the effects Columbus' voyages had on Spain.

Columbus’ exploratory voyages had several effects on Spain. Because of his exploration new foodstuffs were introduced, Spain became more powerful, and the Age of Exploration was enhanced. As exploration continued, Spain gained land and treasures from what are now Mexico and Peru, including rich silver mines. These riches brought new found, although temporary, power for Spain. As Spain’s influence grew, other countries expanded their explorations to the New World as they attempted to reap the benefits that new land and wealth bring.


Although, Columbus did not find a route to Asia, he did find land that was unfamiliar to Europeans.  These lands were inhabited by native people who introduced the voyagers to new vegetation such as corn, potatoes, and tomatoes. These foods were introduced in Spain and other European countries becoming mainstays in European diets.


Columbus indirectly changed the course of history for Spain by opening avenues for further exploration.

In Lois Lowry's The Giver, why does the Giver tell Jonas to stay away from the river?

In chapter 18, Jonas asks the Giver about release. The Giver tells him about the previous Receiver-in-training, Rosemary, and what happened when she was released after just five weeks of training and memories. All of the memories she had received during that time flooded back to the citizens of the community and he had to help them cope with all of those feelings. Jonas wondered what would happen if he just happened to fall into the river and drown. The Giver said that Jonas has many more memories than Rosemary had; so, if he died, the community would suffer worse than they did after her release. Jonas tells him not to worry because he just happens to be a good swimmer. The Giver responds with the following remarks:



"'I'm glad you're a good swimmer, Jonas. But stay away from the river.' He laughed a little, but the laughter was not lighthearted. His thoughts seemed to be elsewhere, and his eyes were very troubled" (181).



The Giver seems to suggest staying away from the river as a serious joke. As oxymoronic as that sounds, he probably feels it's better not to tempt fate even if Jonas is a good swimmer. However, this conversation seems as if it might have planted seeds into the Giver's mind about a plan he later reveals to Jonas. When the Giver tells Jonas to flee the community and to cross the border, it may have been from his experience with Rosemary as well as this conversation about the river that gave him the plan to overthrow Sameness. 

What are poet Robert Frost's contributions to literature?

Robert Frost is one of the most popular modern American poets. Because his career as a writer began to take hold just after the turn of the century, he can be considered one of the 20th century's greatest poets. His work is widely anthologized and taught at all levels of education. One reason Frost's poems can be taught to students of a wide age range is that the language he uses is generally fairly simple. This is one aspect of his work that sets him apart from other modern poets working in the early 20th century. But despite the use of simple language, Frost often conveyed complex ideas in his imagery and settings. Some of his poems seem to be simple descriptions of outdoor activities (such as "After Apple Picking") or fairly uneventful journeys (as in "The Road Not Taken"). And images of nature are also prominent in Frost's poetry, earning him a reputation as a nature poet. But in many of his poems, Frost explores ideas about the human condition, in particular the arc of a person's adult life and career, and their attitudes towards death.


Lines like "I have promises to keep, and miles to go before I sleep" (from "Stopping by Woods on a Snowy Evening") have layers of meaning. At face value, the narrator is simply stating that he has an engagement and must hasten on his way to meet the people waiting for him, and has a long way to go before his night ends. But the poem can also be read as a meditation on how one approaches the later years of one's life: deciding to live life to the fullest before the inevitability of death.

How does ''A bullet only costs about two cents, and anybody can afford that," the last line of Chapter 2 in The Absolutely True Diary of a...

At the end of the second chapter of The Absolutely True Diary of a Part-time Indian, Junior says, "A bullet only costs about two cents, and anybody can afford that" to comment on the state of poverty in which his family exists. Junior's father has to shoot their dog Oscar because they cannot afford vet care for him. Junior has to carry Oscar out to the yard, and he thinks the dog knows exactly what his fate is going to be. Junior reasons that poverty doesn't make anyone stronger in terms of perseverance; he thinks being poor just teaches people how to continue being poor. Junior says poverty is an "ugly circle" in which he and others around him are caught. Junior's sentiment can be related to life today because there are many people caught in cycles of poverty. Income inequality allows some to reap extraordinary benefits and opportunities while others struggle just to make ends meet for their basic survival.

A cart with a mass of 65kg is being pulled by a force of 270 N. A friction force of 83 N opposes this motion. a. Calculate the weight of the cart....

(a) The mass is 65 kg, we're under normal Earth gravity of `9.8 m/s^2` , so the weight is the product of those: `(65 kg)(9.8 m/s^2) = 637 N`
(b) The net force on the cart is the sum of four forces: gravity, the normal force which exactly cancels gravity to hold the cart on the ground, the pulling force, and friction. Because the normal force cancels gravity, the net force is just the pulling force of `270 N ` minus the friction of `83 N`, so `F = (270 N) - (83 N) = 187 N`

(c) The acceleration can be found by `F = ma` , which solved for a is `a = F/m = (187 N)/(65 kg) = 2.9 m/s^2`

Can you help me analyse this image? I am looking for how the image highlights the internal and external factors that impact Macbeth's actions in...

I think you have a good start.  I would agree with your observations, and add to them:


The fire is very significant.  In the image, it is literally inside Macbeth.  It is consuming him from within, just as his ambition, jealousy and later paranoia consume him from within.  First, these qualities lead to his moral disintegration, and eventually his physical death.  Once a fire is started, it tends to spread out of control.  That is what happens to Macbeth.  Once he starts on the path of illicit violence, his choice sets in motion forces both within and outside of himself that he cannot control. 


Note also that the fire is burning in the background of the battle scene.  It is consuming Scotland as well as Macbeth.  This is appropriate, because Macbeth and Lady Macbeth between them manage to do a lot of damage to the whole country.  So, the fire is an internal force that eventually becomes an external one when the inner burning starts to have outer effects.  


I am not sure the battle scene is showing Macbeth's glorious past as a soldier.  It may be the final battle in which Macbeth meets his end, to the great loss of Scotland. 


Note that in the image, almost every other image is "inside" Macbeth.  I think this suggests that they are almost all internal forces.  Their influence interacts with Macbeth's secret desires to cause him to take the actions he does.  


For example, the witches give an ambiguous prophecy which turns out not to be true in the sense that it first appears.  But Macbeth, hearing it through the filter of his pride and ambition, takes the prophecy as a license to go ahead with his coup.  


Similarly, Lady Macbeth (note the cold look on her face) influences her husband by giving him a rationale or justification for acting out his darkest desires.  He would not have given in to her urging unless there was a similar desire in himself, alongside his conscience which initially held him back. 


Not having seen the movie, I am not sure whether Banquo appears in this image.  His ghost might be suggested by the ruin or graveyard that is visible behind the witches, or even by the stained-glass window at the top of the image. 


I assume that the figure on horseback looking out over a cliff is Macbeth himself, but it could possibly be Banquo.  Both are, in a sense, in a position of looking out over Scotland (either to rule or seek what is best for Scotland), and both find themselves poised on the edge of destruction.


Hope this helps.

What are some examples of kidney diseases, and what variables influence how they function?

The kidneys are a pair of vital organs that remove toxins, waste, and extra water from your blood.  After substances are filtered out of blood, they travel through the ureter to the bladder for storage until they can be passed through urine.


Diseases that progressively damage the kidneys and impair their ability to function are referred to as Chronic Kidney Disease (CKD).  If the kidneys are malformed during fetal development, they won't function as efficiently as fully formed kidneys.  Genetic diseases, such polycystic kidney disease, can impair kidney function because it damages the organ's tissue.  Lupus, an immune disorder, can reduce kidney function by causing inflammation in the kidney's filtration system.  This is referred to as lupus nephritis.   Kidney stones are accumulations of minerals that can become lodged in renal tissue, causing damage.  Individuals with diabetes often experience hypertension which can decrease the functioning capabilities of the kidney.  It is unclear why, but occurrence of diabetes varies depending on a persons' ethnicity


If a person's kidney disease progresses to the point where the damage is irreversible, they may experience kidney failure. At this point, they may like dialysis or transplantation, to help their body remove toxins and waste from their blood stream.

What are the origins, immediate causes, course of phenomenon and consequences of the Shoah/Holocaust?

Shoah, Hebrew for catastrophe or calamity, has become a preferred term among Jewish people referring to the events of the Holocaust.


The origins of the Holocaust can be traced back to German anti-Semitic sentiment as early as the Middle Ages. The mid to late 1800s brought the Völkisch movement, which espoused a pseudo-scientific view of Jewish people as a race threatening the purity of the Aryan race. These ideas were highly influential to the development of Nazi ideals.


Germany’s anti-Semitism had three main sources—cultural, racial, and religious. Immediate causes of the Holocaust include economic pressure from the Great Depression. Before Hitler came to power, the medical community was already starting to promote euthanasia as a cost-saving measure and eugenics to encourage racially valuable traits and get rid of racially undesirable traits. Hitler’s 1925 autobiography Mein Kampf admits to hatred of Jews and announced his intention to remove them from participation in German society.


The course of the phenomenon progressed from the Nazi party taking power in 1933 and Hitler becoming chancellor. Throughout the 1930s, the rights of Jewish people in Germany were increasingly restricted. The first concentration camp was established in Dachau, originally imprisoning Communists. In 1938, the terror increased on Kristallnacht, the “Night of Broken Glass,” when Nazis attacked and vandalized Jewish people, synagogues, and businesses throughout Germany and Austria, and 30,000 Jews were sent to concentration camps. By 1940, Jews were forced into ghettos. Nazis began deporting Jews and carried out the first mass murder of Jews in Poland. By 1942, Nazi officials planned to kill all European Jews. In 1944, Hungarian Jews were deported to the Auschwitz concentration camp where they were murdered. The loss of Jewish life is estimated at close to six million people.


Consequences of the Holocaust include the plight of displaced persons, often without surviving family members and facing persistent anti-Semitism in their home countries. An estimated 170,000 Jewish survivors immigrated to Israel by 1953, but many faced economic hardship there. Of the hundreds of thousands of Nazis responsible for these injustices, only 31,651 Nazis went to trial. The long-term cultural, social, and psychological effects of this large-scale genocide are still being felt.

What are some metaphors in Harper Lee's To Kill a Mockingbird?

One of the most famous metaphors in Harper Lee's To Kill a Mockingbird is said by Atticus to Scout early in the novel. In Chapter 3, after Scout has had a very disappointing first day of school, Atticus uses a metaphor to teach Scout the principle he lives by of understanding, accepting, and respecting other people:



You never really understand a person until you consider things from his point of view-- ... --until you climb into his skin and walk around in it. (Ch. 3)



Scout takes this message very much to heart, and it comes up several other times in the book. By the final chapter of the novel, Scout has grown enough that she can reword the metaphor on her own:



One time [Atticus] said you never really know a man until you stand in his shoes and walk around in them. (Ch. 31)



Scout recalls Atticus's lesson in understanding and accepting others as she stands on the porch of Arthur Radley and sees the neighborhood through his eyes. As she does so, she thinks about how Arthur observed the activities of "his children" with feelings of generosity, care, and even concern.

Another important metaphor is spoken by Atticus to Jem and helps develop the theme concerning courage. Jem has just had his experience with Mrs. Dubose in which he learns to see her as not just a cantankerous, hateful old woman but as a truly great lady due to her bravery. Atticus had wanted Jem to spend time reading to Mrs. Dubose with the express purpose of teaching him the true meaning of courage. Atticus uses a metaphor to explain what he wants Jem to see courage as being:



I wanted you to see something about [Mrs. Dubose]--I wanted you to see what real courage is, instead of getting the idea that courage is a man with a gun in his hand. (Ch. 11)



Atticus continues to explain that he wanted Jem to see courage as the ability to undertake a task one is unlikely to succeed in but following through with it regardless, simply because one knows it is the right thing to do, a message that is a central premise of the book.

How does Harper Lee foreshadow the guilty verdict?

There are many times throughout the novel where Atticus alludes to the fact that he knows he won't win the trial for Tom Robinson. These allusions are mixed in with the hope that he will win, but because of the prejudiced feelings of the people of that time period, there is always that sense of reality that tells him that he's fighting a losing battle. Friends, such as Link Deas, even say he'll lose, but that doesn't stop Atticus from standing up for what is right and doing his best for his client. In chapter nine, Scout asks her father if he is going to win the case and he says "No, honey." She then asks him why he is doing it. He responds with the following:



"Simply because we were licked a hundred years before we started is no reason for us not to try to win" (76).



Atticus is referring to the fact that the case will be fighting against racial prejudice more than any real evidence condemning Tom Robinson. This is definitely a hint to the future guilty verdict . Another example of a foreshadowing to the guilty verdict is when Atticus is talking with his brother Jack about it. Atticus says that the case is tough because of the following:



"The only thing we've got is a black man's word against the Ewells'. The evidence boils down to you-did--I didn't. The jury couldn't possibly be expected to take Tom Robinson's word against the Ewells'" (88).



Atticus gives the reader an insight into Maycomb's way of life. White people side with their own; and as long as they are in complete control of everything, they won't allow an African American's word to take precedence over a white man's. The case is most-like going to fail because of this prejudiced way of thinking.


Finally, there's one more quick foreshadowing that happens right when the jury comes in from their deliberations. Scout is watching them come back into the courtroom in chapter 21 and she says the following:



"A jury never looks at a defendant it has convicted, and when this jury came in, not one of them looked at Tom Robinson" (211).



The verdict is read immediately thereafter; but at this point, the verdict still hasn't been read. Tom could still be acquitted. Maybe Scout's assessment of the jury is wrong. Unfortunately, she is exactly correct; but the this foreshadowing right before the verdict is actually read does a great job creating suspense for the reader.

What is a sentence in Romeo and Juliet that has sight imagery in it?

While Shakespeare's Romeo and Juliet is full of outstanding imagery, the most famous example of imagery which appeals to sight is probably Romeo's declaration of Juliet's beauty when he first sees her across the room during Capulet's party in Act I, Scene 5:



O, she doth teach the torches to burn bright!
It seems she hangs upon the cheek of night
As a rich jewel in an Ethiop’s ear—



For Romeo, Juliet is literally the brightest light in the room, brighter than the numerous torches which would be needed for Capulet's hall. Her beauty is also as stunning as a "jewel" in the ear of an "Ethiop." This reference most certainly brings up the image of a dashing black man, maybe wearing a turban and a cloak, who is wearing a beautiful diamond, ruby, or emerald in his ear. This may have been just the sort of man who Romeo has seen previously in Verona. He may have been a trader or an envoy for some African nation. Numerous other references to Juliet that reference light or brightness appear later in the play, especially in the balcony scene.

What information is used to predict chemical reactivity of an element?

Chemical reactivity of a substance simply means the information regarding how it will react with other substances and what sort of chemical reactions it will undergo.


One of the most important predictive factors of chemical reactivity of an element is the number of valence electrons it has. These are the electrons in the outermost shell of an element and can be determined by knowing the electronic configuration of a given element. The valence electrons will determine how many more electrons are required to completely fill the valence orbital. Knowing the number of valence electrons, we can figure out if the electrons will be donated or gained or shared, in order to achieve the noble gas configuration. 


For example, sodium is a metal and has 1 valence electron. Sodium donates this valence electron and undergoes ionic bonding, especially with strongly electronegative elements (such as halogens). The reactivity of other elements can be similarly predicted. 


Hope this helps. 

What is the relationship between the embryo and the fetus?

Embryo and fetus are terms for a developing organism; they merely indicate different times during development. For humans, the embryo is an early stage of development, from approximately the fourth week after fertilization of an egg until about week 11. You will also see "embryo" refer to all early development from fertilization till week 11. Technically, the stages are fertilized egg (or zygote), blastula (a ball of undifferentiated cells), gastrula (the stage when indentation of the ball of cells occurs, and tissue layers form), and embryo. While the developing child is an embryo, its organs are forming and it begins to look somewhat human. At 11 weeks, most systems have begun to form; the developing human is now termed a fetus. This stage lasts until birth, and involves further growth and development.


Other animals go through this process, and the same terms are used. The time for each stage varies.

What are the steps for testing non-reducing sugar?

Non-reducing sugars do not have the aldehyde group and so they cannot reduce copper sulphate like reducing sugars would do when tested with the Benedict’s reagent.


To test for non-reducing sugar, therefore, an indirect test will have to be conducted by first hydrolysing (breaking down) the non-reducing sugar to its constituent monosaccharides (reducing sugars). The sample can then be tested for the presence of reducing sugars with Benedict’s reagent.


The steps to take would be as follows. First, the reducing sugar test would need to be carried out on the sample to ensure that a reducing sugar that may confuse the result of the test is not already present in the sample (see the source link below for the reducing sugar test with Benedict’s reagent). The reducing sugar test should be negative if reducing sugar is not already present in the sample.


The next step is to hydrolyse the sample into reducing sugars. Add 1cm cubed of dilute hydrochloric acid to 2cm cubed of the sample. Mix and boil the mixture for about 2 – 3 minutes. Allow the mixture to cool and then neutralise it by adding sodium hydrogen carbonate until the solution is slightly alkaline. Benedict’s reagent will only work in an alkaline environment, so check with a blue litmus paper to detect when the solution turns alkaline.


Perform the reducing sugar test on the mixture by adding 2cm cubed of Benedict’s reagent. The solution turns clear blue. Insert the test tube in boiling water for about five minutes. If the solution remains clear blue, it means the solution does not contain any reducing sugars.


An orange-red precipitate forms if reducing sugar is present. You can then deduce that non-reducing sugar was originally present because a negative result was obtained the first time the sample was tested for reducing sugar but a positive result is now obtained when the non-reducing sugar was hydrolysed to reducing sugar after hydrochloric acid was added.

How does Poe create suspense in "The Pit and the Pendulum"?

I think that a big part of the suspense in "The Pit and Pendulum" comes from two sources.  


The first is the unknown. The reader has no idea why the protagonist has been arrested and sentenced. The opening paragraphs have him in and out of conscious thought all while hallucinating. We don't know who he is or what he has done to deserve punishment. Once he is in his cell, the unknown continues. It's too dark to see anything, so the protagonist (and reader) has no idea where he is. After he successfully evades the pit, the protagonist must face the pendulum. There is always a sense of "what could possibly come next?" That's suspenseful reading.  


The second source for suspense is the protagonist's solitude. Being alone in an unknown place is scary. Having to suffer alone is scary. If the narrator had a cellmate, then readers might hope the two could at least help each other cope. That isn't an option for the protagonist, though. He must go about his torture alone. He's only dependent on himself, which I believe makes the story more suspenseful.

In Animal Farm, why don't the pigs like the pet raven Moses' stories about Sugarcandy Mountain?

In Animal Farm, Sugarcandy Mountain is a place where it is "Sunday seven days a week," where "lump sugar" grows on the hedges and "clover" is in season "all year round." As its name suggests, it is the animal equivalent of Heaven and its story is spread around the farm by Moses, the lazy and troublesome raven.


There a number of reasons why the pigs do not want Moses to tell the animals about Sugarcandy Mountain. First, this place acts as an unwelcome distraction on the farm. If the animals are dreaming of Sugarcandy Mountain, they are escaping from the realities of everyday life, like working hard and obeying the pigs. For the pigs, too much dreaming might cause laziness and promote lethargy.


Second, Sugarcandy Mountain poses a potential problem to the social order on the farm. If the animals are thinking about this utopia where all animals are equal, they may realize they are treated differently than the pigs. They may become aware that the pigs eat more and have greater control over the operation of the farm. If this happens, there is a danger that the animals will rise up and rebel.

How does Ruth support Walter in A Raisin in the Sun?

Ruth often puts her own needs and desires on the back burner for the sake of Walter’s dreams of owning a bar. She agrees to talk to his mother about giving her insurance money to him, even though she is reluctant about his choice. Ruth might not agree with Walter’s choices, but she does not seriously try to talk him out of them. Just as she supports Beneatha’s dream of being a doctor, she supports Walter’s dream of owning his own business. Privately, or with other characters, she may give a hint of her own doubts, but face to face she is supportive. When she finds out she is pregnant, she considers an abortion out of her fear that another child will put an undue burden on Walter to accomplish his dream. Whether she is wise to support Walter to the extent she does is questionable. How much should she look out for the family as a whole and admit that Walter has not been an adequate provider? In the end, Walter takes up his responsibilities and thinks more of the family than of himself. This has been Ruth’s desire all along: to give Walter the chance to do this.

Why do the mother and Maggie react awkwardly towards Dee in "Everyday Use"?

Maggie and the mother react awkwardly towards Dee because of the inherent differences between their identities and culture. In addition, Maggie and the mother expected to see a modern woman because Dee went to a city college. Instead, Dee shows up in a long African dress and jangling earrings. Dee also changed her name to Wangero Leewanika Kemanjo in reference to her African roots. All these changes came as a shock to both her mother and Maggie. Before she left for college, Dee was not happy with her family’s lifestyle or culture; upon her return, she seemed in touch with her origins. Dee asked for the butter churn her uncle made. She also asked for the handmade quilts pieced by her grandmother and assembled by her mother and her sister. The mother tells her the quilts were already promised to Maggie. Dee tries to take the quilts, but her mother takes them from her and offers her machine-stitched quilts instead.

How does the the sniper feel about the war at the beginning of the story?

The only hint in the beginning of the story about how the sniper feels about the war (in a mostly detached narration of his activities) appears in the second paragraph when the third person narrator refers to him by saying, "his eyes had the cold gleam of a fanatic." A fanatic is someone who is totally dedicated to a cause so the reader must assume that the Republican sniper is committed to his role in the Irish Civil War. The Republican army was steadfast in its opposition to Ireland's recent treaty with Great Britain. The history of the Irish Republican army often involved men who would rather die than live under the hegemony of the British and this sniper may have been just such a man. The sniper tends to do things without remorse, including killing an armored car commander, as well as a lady he perceives to be an "informer" who is out to reveal his position above the streets of Dublin. He is methodical in his tricking of the Free-State sniper and his killing of that enemy. Thus, it could certainly be argued, especially at the beginning of the story, that the sniper was in favor of the war because it was in support of giving Ireland its complete freedom. 

What were the social impacts that slave trade had on Africa?

The Atlantic slave trade had a variety of negative social effects on Africa. The European exploitation of African resources and human labor, as well as the constant demand for slaves to export to North America, was devastating to African society. Millions of Africans were taken as slaves, and local leaders waged war on neighboring groups to take prisoners of war to sell as slaves to Europeans. The slave raids within Africa resulted in famine, and many taken as slaves died on the route to the coast or on slave ships. Inter-ethnic conflict increased as a result of the slave raids, and African society was increasingly dominated by warlords who sold slaves for personal profit at the expense of Africa's economy. The fear of neighboring warlords caused some ethnic groups to migrate, resulting in economic and technological regression for the migrants. African society also restructured itself by creating a more rigidly hierarchical and authoritarian society in the hopes of protecting themselves against the slave trade. The Atlantic slave trade damaged Africa's economy, changed its governmental structures to predatory or authoritarian systems, caused mass displacement, and greatly reduced the population as people were taken as slaves or died in the process. Overall, the slave trade severely damaged African society.

What does the mud hut in Khaled Hosseini's The Kite Runner represent?

The mud hut in The Kite Runner is one symbol of the great contrast between Amir and Hassan and Baba and Ali. It also serves as a reminder that how one begins in life does not necessarily dictate one's worth. 


Baba and Amir live in "the most beautiful house in... the district," with floors of marble, chandeliers of crystal, four bathrooms, leather chairs, and custom-made cabinetry (4). Ali and Hassan are in a "little shack," which has no electricity, apparently no plumbing, and is clean, but sparsely furnished with mattresses for Ali and Hassan, one table, one worn rug, and a wooden stool (6). The mud hut is at the end of one of the gardens, far from the house. 


Baba and Amir are Pashtuns and Sunni Muslims, part of the ruling class of Afghanistan. Ali and Hassan are Hazara and Shi'a Muslims, part of the underclass of the country. They are the servants. Baba and Amir are the masters. 


Hassan is a good person, faithful friend, generous, hard-working, and honest, but Amir is an envious, cowardly, dishonest child. I think this shows one's environment need not control one's behavior. 


Housing can function quite well as a symbol, and it does so in this story. It shows us that no matter how humble one's beginnings may be, one can rise above them and be of good character.

In the musical "The Phantom of the Opera," what significant item does Christine leave for the Phantom at the end of the show?

In Act Two of The Phantom of the Opera, Christine stars as the leading role on the opening night of Don Juan Triumphant. Although she is tasked with singing with Ubaldo Piangi, she soon discovers while on stage that she is instead singing with the Phantom himself. The Phantom then kidnaps Christine and brings her to his lair, where he attempts to force her to marry him in order to save the captured Raoul's life. Christine kisses the Phantom, which changes his mind and causes him to agree to release the lovers.


Before fleeing the lair with Raoul, Christine returns the ring that the Phantom had given to her, and he professes his love. This is a powerful moment in the musical, as the Phantom is experiencing something he had not experienced before: true feelings for another human being and a willingness to show compassion. 

What do you know about Nnaemeka's father in "Marriage is a Private Affair"?

If we are discussing "what we know" about Nnaemeka's father, Okeke, then we are discussing aspects of his character. First, we know that Okeke values Ibo tradition more than anything else at the beginning of the story. Living in a rural Ibo village in Nigeria, there are many traditions to which Okeke adheres. For example, Okeke believes strongly that he should follow Ibo tradition and choose a wife for his son. According to Ibo tradition, wives must be Christians, good homemakers, and (above all) be of the Ibo culture. Nnaemeka rejects these traditions by falling in love with Nene and choosing to marry her instead of the Ibo maiden that Okeke has chosen for his son. For eight years, Okeke stubbornly disowns his son, even to the point of ripping his son's new bride out of their wedding photo. However, it is important to note that Okeke changes over the course of the story. The impetus for the change is Nene's letter about Okeke's two grandsons and how they wish to interact with their grandfather. This causes Okeke to cling to family over tradition and agree to meet with his grandsons. By the end of the story, Okeke only hopes that he lives long enough to "make it up to" the family.

Integral of sec^n(x)dx

You need to use reduction formula to integrate the function, such that:


`int sec^n x dx = int sec^(n-2) x* sec^2 x dx`


You need to use integration by parts, such that:


`int udv = uv - int vdu`


`u = sec^(n-2) x => du = (n-2)*sec^(n-3) x tan(x)`


`dv = sec^2 x => v = tan x`


`int sec^(n-2) x* sec^2 x dx = tan x*sec^(n-2) x - (n-2)*int sec^(n-3) x*tan x dx`


`int sec^(n-2) x* sec^2 x dx = tan x*sec^(n-2) x - (n-2)*int sec^(n-2) x*tan^2 x dx`


You need to replace `sec^2 x - 1` for `tan^2 x` , such that:


`int sec^(n-2) x* sec^2 x dx = tan x*sec^(n-2) x - (n-2)*int sec^(n-2) x*(sec^2 x - 1) dx`


`int sec^(n-2) x* sec^2 x dx = tan x*sec^(n-2) x - (n-2)*int (sec^n x- sec^(n-2) x) dx `


You need to put `I_n = int sec^n x dx,` such that:


`I_n = tan x*sec^(n-2) x - (n-2)*I_n + (n-2)*int sec^(n-2) x dx`


`I_n + (n-2)*I_n = tan x*sec^(n-2) x + (n-2)*int sec^(n-2) x dx `


`I_n*(n - 2 + 1) = tan x*sec^(n-2) x + (n-2)*int sec^(n-2) x dx `


Put `int sec^(n-2) x dx = I_(n-2)`


`(n-1)*I_n = tan x*sec^(n-2) x + (n-2)*I_(n-2)`


`I_n = 1/(n-1)* tan x*sec^(n-2) x + (n-2)/(n-1)*I_(n-2)`


Hence, evaluating the given integral, using reduction formula yields `I_n = 1/(n-1)* tan x*sec^(n-2) x + (n-2)/(n-1)*I_(n-2).`

What are at least three ethical issues displayed in the 2011 film, The Help? Please provide examples.

One ethical issue portrayed in the movie The Help (2011) is the way in which parents neglect their children. For example, Elizabeth Leefolt ignores or humiliates her young daughter, Mae Mobley. Elizabeth's main interaction with her daughter is to disparage or discipline her, which Elizabeth's maid, Aibileen, sees but cannot comment on. Aibileen is not allowed to comment because she is African-American and Elizabeth is her white employer, creating a power dynamic in which Aibileen sees the way in which Elizabeth, who is suffering from postpartum depression, ignores her daughter but cannot voice her concerns.


Additionally, the way the maids are treated creates several ethical issues. Skeeter's mother, Mrs. Phelan, fires their long-time maid, Constantine, just because Constantine's daughter, Rachel, challenges Mrs. Phelan's friends about why they don't include her in their all-white organization, the Daughters of the American Revolution, and eats with the white women instead of staying with the African-American help. This is an ethical dilemma because Mrs. Phelan fires Constantine in an instant after Constantine has spent much of her life working for the Phelans.


Finally, while Skeeter achieves a great moral victory by publishing the stories of the African-American women and giving them a voice, her secrecy and anonymous publishing of these stories creates an ethical dilemma. Is she right to deceive her family and friends? Some readers might think so, but it is still an ethical question.

Why does Johnny say “there’s got to be some place without greasers or Socs" in The Outsiders?

Johnny is frustrated with having to feel fear every time he sees a group of Socs. 


In this chapter, Johnny and Pony are afraid that they are about to get into a fight when a blue mustang drives by.  The boy in the mustang, Bob, is the same one who was one of the group that attacked Johnny before.  The experience left him traumatized and afraid of his own shadow. 


Johnny and Pony met two Soc girls at the movies, and they hit it off.  However, the girls’ boyfriends turn out to be the same ones who attacked Johnny.  The whole experience frustrates him.  He is tired of being judged by Socs, and tired of being scared in general. 



"I can't take much more." Johnny spoke my own feelings. "I'll kill myself or something."


"Don't," I said, sitting up in alarm. "You can't kill yourself, Johnny."


"Well, I won't. But I gotta do something. It seems like there's gotta be someplace without greasers or Socs, with just people. Plain ordinary people." (Ch. 3)



Johnny, Pony and Two-bit enjoy hanging out with the Soc girls.  When they are together, they are just kids being kids.  They can mostly forget about the different classes and gangs.


Johnny wishes that he did not have to worry about being jumped just because he is a greaser.  This is why he says that it would be better if there are no gangs.  He doesn’t want to be a target any more.  It is wearing him down.


It is ironic that Pony says he would like to go to the country, because that is where Johnny and Pony go after they are attacked by Bob.  Johnny killed Bob because he was scared to death and under stress. He thought that Bob was drowning Pony in the fountain.


Later, when Johnny is dying, he says that he did not get a chance to live.  He died too young, and his life was rough.  As bad as Johnny’s life was, he did not feel as if it was long enough.  The conflict between the greasers and Socs has now led to two deaths.  (There will be third when Dally essentially commits suicide out of grief over Johnny's death.)

What are the four key beliefs about Mary?

Thomas Jefferson's election in 1800 is sometimes called the Revolution of 1800. Why could it be described in this way?

Thomas Jefferson’s election in 1800 can be called the “Revolution of 1800” because it was the first time in America’s short history that pow...
