Read the passage from Animal Farm. By the late summer the news of what had happened on Animal Farm had spread across half the county. Every day Snowball and Napoleon sent out flights of pigeons whose instructions were to mingle with the animals on neighbouring farms, tell them the story of the Rebellion, and teach them the tune of "Beasts of England."

Which social insight does Orwell develop in the passage?

Corrupt leaders use propaganda to push their agendas.
Oppression over many people can be devastating.
Dystopian societies live by specific modes of conduct.
Educated people will not give in to totalitarianism.
