"may men of merit be motivated to act!" is an alliteration quote from Old Major in the book animal farm.
One instance of alliteration in Old Major's speech is: ""Is it not crystal clear, then, comrades..."
Chapter 10.
I believe it was Old Major in Chapter 1 of Animal Farm.
An example of a hyperbole is in chapter 5, when snowball says "Napoleon is always right". No one is completely right 100% of the time.
He is evil..
Snow ball
He is overthrown by the animals and kicked off of the farm in Chapter 4.
Old Major (the old boar who tells the other animals about the possible future of the farm in chapter 1)
Boxer
Chapter 2
Depends on the chapter.
In chapter 7 of Animal Farm, several animals are killed during an assembly of the animals. The animals are killed for being traitors against The Farm.
