Answer and explanation:
This is a passeage from a book called "1984" written by George Orwell and it is considered part of the classic literature. This is a political novel that is about how a citizen, a regular and ordinary man who goes by the name of Winston Smith is tired of how the government controls everyone in order for them to have them (the citizens) acting and thinking and living the way they (the government) want. He does not want to be part of that toxic behaviour, so he revels against the government.
