Read the passage from animal farm. on the third sunday after snowball's expulsion, the animals were somewhat surprised to hear napoleon announce that the windmill was to be built after all. he did not give any reason for having changed his mind, but merely warned the animals that this extra task would mean very hard work, it might even be necessary to reduce their rations. what is the central idea of this passage? the animals cannot believe that snowball is gone. napoleon expects the animals to work harder and eat less. the animals do not understand why they have to build a windmill. napoleon steals ideas from snowball and pretends they are his own.
