Read the passage from Animal Farm.Sometimes the work was hard; the implements had been designed for human beings and not for animals, and it was a great drawback that no animal was able to use any tool that involved standing on his hind legs. But the pigs were so clever that they could think of a way round every difficulty. . . .. . . They met with many difficulties—for instance, later in the year, when they harvested the corn, they had to tread it out in the ancient style and blow away the chaff with their breath, since the farm possessed no threshing machine.
