What actually brought about the rebellion in Animal Farm?Like what caused it?

The animals of Manor Farm are disgruntled with the living
conditions imposed by their human owner, Mr. Jones. Often drunk, Jones allows his
animals to go hungry and without warmth in cold weather. Old Major, Jones' prize white
boar, calls the animals together to unite them against their human master, who he claims
takes without producing. If the animals revolt and rid themselves of the humans, they
will become rich and contented. Humans are enemies of animals, Old Major tells them, and
four-legged creatures deserve the right to be free just as their two-legged
counterparts.

Three days after his speech, Old Major dies,
and the other animals make preparations for a revolt. When the drunken Jones forgets to
feed them, the animals break into the barn and help themselves to the feed. When Jones
and his men arrive with whips, the animals drive them off the farm. "Animal Farm" is
established with a set of commandments for the loyal creatures to
follow.

Why did Father Gilligan grieve? Why did he repent?

The details you need to answer your question are in the
second and third stanzas of the poem.  Here's the first four stanzas, to give you the
full context, of "The Ballad of Father Gilligan," by Yeats.  They include the details
you ask about:

The old priest Peter Gilligan
Was
weary night and day;
For half his flock were in their beds,
Or under
green sods lay.

Once, while he nodded on a chair,
At the
moth-hour of eve,
Another poor man sent for him,
And
he began to grieve.

‘I have no rest,
nor joy, nor peace,
For people die and
die’;
And after cried he, ‘God forgive!
My
body spake, not I!’

He knelt, and leaning on the
chair
He prayed and fell asleep;
And the moth-hour went from the
fields,
And stars began to peep.

I've emboldened
the lines that include what the priest sees as his grievous sin, and italicized his
repentence.  Actually, his reaction is probably quite natural.  Members of his flock are
dying faster than he can deliver the Last Rites to them.  He is dozing off in his chair
when he gets summoned by yet still another dying parishioner.  He is overworked and
exhausted, but when he reacts to the summons in a very human way, he sees his words and
behavior as not fitting for a priest.  He grieves and explodes, figuratively, and then
is immediatley sorry for what he says right after he says
it.

God, in the poem, though, seems to understand.  While
the priest is praying, begging for forgiveness, he falls asleep and misses the man's
dying moments, but God sends an angel in the priest's place to administer the Last
Rites.

In Life of Pi, Pi in the human story is represented by Richard Parker. What does Pi in the animal story represent?He could be the cook, minus the...

Pi, in the animal story, represents his more humane,
decent, polite, religious, polite and controlled self.  Richard Parker, in the animal
story, also represents Pi, just his more barbaric, animalistic self that does all of the
difficult things that enable him to survive.  Pi is thrust into a very difficult
situation, where he is forced to do things that are extremely uncomfortable for him, and
even abhorrent, in order to survive.  He is normally an educated, respectful, vegetarian
boy who would never hurt anyone or anything.  However, if that part of himself reigns,
he would die quickly on the ocean. So, he gives in to his more animalistic side in order
to survive.  He lets that side take over to kill, take control, be dominant, fight the
odds, and survive the tragedies.

Often, in stressful
situations, people have to do things they never would have imagined themselves doing. 
Pi does that here, and embodies all of those horrific acts in the animal of Richard
Parker, a fierce tiger in whose nature it is natural to fight and kill.  Pi separates
himself from the horrible things he does by putting them outside of his normal self.  So
Pi, in the animal story still represents himself, just the human, humane, decent part of
himself, the part that would never do horrible things or hurt others.  He has to
maintain that part on himself in order to remain sane, and to keep a semblance of his
old nature.  So both Pi and Richard Parker, in the animal story, represent Pi, just
different parts of his nature that, in order to survive, work together.  I hope that
those thoughts helped a bit; good luck!

What is Atticus's strategy; in other words, his plan of defense in the Robinson case?I dont understand Atticus's plan in the Tom Robinson case. It...

If you are looking for this in Chapter 9, you are going to
need to look at the end of the chapter where Atticus is talking to Uncle Jack.  He
doesn't say a whole lot about the strategy, but he says a
little.

First, Atticus says that it is a case of Tom
Robinson's word against the Ewells' words.  He does not think he can win that way.  So
we see his defense is to try to make the Ewells look like liars and to use Tom's words
in his own defense.

He also says he intends to shake the
jury up a bit, but we do not really know what he means by that.

What is the significance of Piggy's plea to join the expedition in Lord of the Flies?

In the first chapter, when Ralph, the newly appointed
chief says they need to see if they are indeed, on an island, and therefore they need to
explore, Piggy says he wants to go with Ralph, Jack, and Simon.  Ralph tells Piggy that
he's no good on a job like this; Jack just says, "We don't want you." The significance
is that Piggy is the voice of reason and intellect - a voice needed among the boys. 
Piggy does not get any respect from Jack and even Ralph is slow to show him much,
but Piggy wants and deserves respect.  Piggy even tries another tactic by telling Ralph
that he was hurt that Ralph told the boys his nickname was "Piggy".  Ralph makes Piggy
feel a little better by telling him it could be worse, and that it was Piggy's job to
get the names of all the other boys.  This shows that Ralph has empathy for Piggy, the
sign of the civility which the reader sees in Ralph throughout the
story. 

JUST TIPs will help! Rubber band cars, have my own ideas also i like you to hear.need to make a rubber band powered car that runs at least 6...

Hmmm. For the wheels and axles, you could use plastic
drinking straws, and the plastic lids from cups that you get at fast food places. If you
have some sort of a plastic box or bowl that has holes in the sides, you could put the
straws through the holes, and thread the lids on so they would turn like wheels. You'd
have to secure them with string, or something similar; maybe bread bag ties. I am not
sure how you can get them to run off the rubber bands, but I am thinking of those balsa
wood toy airplanes we all had as kids. Twist the bands, and as they unwind, they would
have to turn the "axles" (straws) of the car.

Hope this
helps some!

What are some internal character traits of Scout Finch in the beginning of the story and what are some at the end of the story?

INTERNAL
CHARACTER TRAITS
OF JEM
FINCH.

We know that Jem still
has feelings for his mother during the early chapters of To Kill a
Mockingbird. Scout does not remember her mother (she was very young when her
mother died of a heart attack), but Jem does.

readability="9">

He remembered her clearly, and sometimes in the
middle of a game he would sigh at length and then go off and play by himself behind the
car-house. When he was like that, I knew better than to bother
him.

Jem has become sort of a
mother hen to Scout by the end of the story. He gives her advice, comforts her when
necessary, and in Chapter 28, he walks her to and from the Halloween carnival. When the
mysterious attacker (Bob Ewell) goes after Scout, Jem fights him off. He succeeds in
keeping Bob away until Boo comes to their
rescue.

INTERNAL
TRAITS OF
SCOUT
FINCH

Scout's temper gets the
best of her often in the early chapters of the novel. She is ready to fight at the drop
of a hat, and she is warned by Atticus that he "will wear me out" if she continues. By
the end of the novel, Scout has grown three years older and has matured dramatically.
She actually entertains lady-like ideals on occasion, and she learns to hold her temper
when she is tempted. She is also able to distinguish fantasy (the stories about Boo
Radley) from fact (Miss Gates' conflicting statements concerning Maycomb's Negroes and
Hitler's treatment of the Jews).
