Is Weena necessary to the story of the Time Machine?

Weena is the only representative of the Eloi that the Time
Traveler becomes very familiar with.  She represents all that is good and bad about this
future race of people that is bred like cattle by the Morlocks.  It is through observing
her behavior that the Time Traveler learns about the relationship between the Morlocks
and the Eloi.

In the story, Wells only gives names to
characters that are important, and Weena is one of them.  We are given an emotional
attachment to Weena and begin to care about the Eloi through her. Without her we might
not care enough about the Eloi or what the Time Traveler tries to do, and the story
would not have the emotional impact that it has.

In Going After Cacciato, who is Cacciato and what does he represent?

Cacciato is an American soldier during the Vietnam War who decides to leave his squad and go AWOL.  I think it can be argued that he represents control; specifically, the strict control and order wielded by the military structure.  When he decides to desert, he undermines that control, and the men must hunt him down in order to reestablish the order and discipline they need to survive in battle.

Control is a central theme in the story.  In his recollections, Paul is more naive than his comrades, and is not always sure about what he should do in a given situation.  This indicates a lack of control on his part, a deficiency which is accentuated when, at a moment of crisis, he loses control of even his physical body and wets himself.  The theme of control also extends to the larger war effort, and the need for absolute observance of military protocol on the part of an effective war machine.  When that control is compromised, as evidenced in Sidney Martin's violation of standard operating procedure in searching the tunnels, chaos is bound to ensue.

How do Pip and Joe's relationship change from the start of the novel to the end?Great Expectations by Charles Dickens

While Pip's relationship and view of Joe's friendship
does, indeed, undergo changes as Pip's values alter, from Joe's perspective, there is
absolutely no alteration in feelings or attitude toward Pip.  Even while Pip is a child,
Joe has respect for Pip, complimenting him on being an "oncommon scholar."  He protects
and cares for Pip at every turn.  When Pip bemoans being "common" and having coarse
hands and boots, Joe explains that Pip is not at all common in his heart.  Then, when
Pip is embarrassed by Joe on his London visit and neglects to visit when he is near the
forge, Joe's love is constant.  Rushing to aid the burned Pip, who expresses his
guilt--"Tell me of my ingratitude"--this friend
replies,

"Which dear old Pip, old chap,...you and me was
ever friends.  And when you're well enough to go out for a ride--what
larks!"

Constant in his
friendship for Pip, Joe's words of love echo like a refrain through the entirety of
Great Expectations by Charles
Dickens.

Eliezer is a healthy boy in the beginning of Night. At the end he refers to himself as corpse. What are some significant events that caused that?I...

Elie becomes a corpse by the end of the book for many reasons, but also in two facets: physically and emotionally.

Mrs. Schacter and her son in the train would be a good place to begin.  At first the people were compassionate to an old lady who appears to have lost it a little in a crowded train car.  Then, in front of her young son, the crowd begins to beat her senseless each time she calls out about the fire and flames. 

Obviously, starvation and lack of proper food and nutrition in the camps of Auschwitz, Birkenau and Buna reduce a healthy boy's physique to skin and bones.

In addition, the fact that he begins the "journey" as a loving son who is looking out for and protecting his father and ends up trying to lose him in one of the runs so he doesn't have to worry about anyone but himself will reduce a person emotionally from healthy relationships to corpse-like behavior.  The Nazis continually did things to reduce the Jews from humans to "animals".

Another event which dehumanizes Elie and the others is the loss of Juliak's beautiful violin music.  He was killed and his violin was crushed...a symbol for his soul, but also the human connection.

There are many other conflicts which contribute to Elie's metamorphosis--the fight for his shoes, his gold teeth, and all the selections he faced.  Each of these conflicts made him less human and more like the corpse he sees when the liberators appear.

What causes the fight between the Capulets and the Montagues in Act I, scene 1?

What really causes the fight is the fact that the
Montagues and Capulets hate each other.  They hate each other so much that even their
servants hate one another.

It is these servants who are the
immediate cause of the fight.  Sampson and Gregory (Capulet servants) are walking along
when some Montague servant come out.  Sampson insults them and they start fighting after
a bit of a verbal argument.

When Tybalt comes in, he makes
the fight worse.  Benvolio has been trying to break the fight up.  But Tybalt decides
that he wants to fight Benvolio because he hates Montagues so
much.
