Read the passage from Animal Farm. All through that summer the work of the farm went like clockwork. The animals were happy as they had never conceived it possible to be. Every mouthful of food was an acute positive pleasure, now that it was truly their own food, produced by themselves and for themselves, not doled out to them by a grudging master. With the worthless parasitical human beings gone, there was more for everyone to eat. Which detail best supports the central idea that the animals felt pride in growing and supplying their own food? “All through that summer the work of the farm went like clockwork.” “The animals were happy as they had never conceived it possible to be.” “Every mouthful of food was an acute positive pleasure, now that it was truly their own food.” “With the worthless parasitical human beings gone, there was more for everyone to eat.”
