Read the excerpt from Animal Farm . In the long pasture, not far from the farm buildings, there was a small knoll which was the highest point on the farm. After surveying the ground, Snowball declared that this was just the place for a windmill, which could be made to operate a dynamo and supply the farm with electrical power. This would light the stalls and warm them in winter, and would also run a circular saw, a chaff-cutter, a mangel-slicer, and an electric milking machine. The animals had never heard of anything of this kind before (for the farm was an old-fashioned one and had only the most primitive machinery), and they listened in astonishment while Snowball conjured up pictures of fantastic machines which would do their work for them while they grazed at their ease in the fields or improved their minds with reading and conversation. According to this passage, how would the electricity produced by the windmill most affect the animals? Choose two correct answers.
