To support the central idea that the animals on Animal Farm had a great influence on animals at other farms, the following four key details from the passage can be selected:
- “Rumours of a wonderful farm, where the human beings had been turned out . . .”
- “A wave of rebelliousness ran through the countryside.”
- “Bulls which had always been tractable suddenly turned savage.”
- “Above all, the tune and even the words of 'Beasts of England' were known everywhere.”
These details illustrate the impact of the events at Animal Farm on other animals, demonstrating how the idea of rebellion and the influence of the song spread among them.
