Read the passage from animal farm. At the gate they paused, half frightened to go on, but clover led the way in. They tiptoed up to the house, and such animals as were tall enough peered in at the dining-room window. There, round the long table, sat half a dozen farmers and half a dozen of the more eminent pigs, napoleon himself occupying the seat of honour at the head of the table. The pigs appeared completely at ease in their chairs. The company had been enjoying a game of cards but had broken off for the moment, evidently in order to drink a toast. A large jug was circulating, and the mugs were being refilled with beer. No one noticed the wondering faces of the animals that gazed in at the window. What is the central idea of this passage?.
