Answer:
The plot events that are key parts of chapter 7 are:
* Squealer announces that the animals will no longer sing "Beasts of England.”
* The animals are told that Snowball visits at night and sabotages their efforts.
* Napoleon comes to an agreement with humans to sell them four hundred eggs a week.
* Napoleon orders the dogs to kill several of the animals that questioned his authority
Explanation:
In unit 7 from "Animal Farm" by George Orwell the key events happen in the following order as first Napoleon get to the agreement of selling four hundred eggs a week, thing that the animals didn't like since it was part of the complaints they had towards humans, then the animals hear that Snowball was sabotaging their work at the farm at night and Napoleon blames Snowball of every problem they had, As time passed by Napoleon became more intolerant and dominant and so he put the dogs to kill all the animals that according to him were snowball's allies, Then near the end of the chapter when the rebellion is no longer needed Squealer tells the animals to sing another song instead the one that encouraged them before.
