Answer:
George Orwell uses allegory in Animal Farm for the following purposes:
1. to expose the corruption of the communists in Russia
2. to represent the struggles of the labor class in Russia
Explanation:
In this well-known and widely read Animal Farm, the author employs allegories to freely give symbolic expressions to human figures and actions, using fictional figures, storytelling, and painting of truths in disguise.
Leaders of the Animal Farm come to power promising ideal conditions for the citizens. Before long, they fall into complacency because the temptation to live a more luxurious life and pursue personal interests is higher for leaders in power as they too often forget their campaign promises and backgrounds. The citizens must ensure that there are "checks and balances" to ensure that, for example, a democratically elected president "does not legislate from the bench."

Answer: 2- The poet repeats the word “perched” to show that the raven is threatening to the speaker, and this contributes to the mood of powerlessness in the poem.
Explanation: repetition is a literary device that consists in repeating certain words or phrases in a sentence or paragraph, in order to create an impact in the reader. In the given excerpt from "The Raven" we can see an example of the repetition of the word "perched" this shows that the raven is threatening to the speaker (it is always watching the speaker) and this contributes to the mood of powerlessness in the poem (because the speaker doesn't seem to be able to do something to stop the raven from watching him).
