Which of the following quotations best describes how the animals feel about their work on the windmill?
"All that year the animals worked like slaves. But they were happy in their work; they grudged no effort or sacrifice, well aware that everything that they did was for the benefit of themselves and those of their kind who would come after them, and not for a pack of idle, theiving human beings."
"When the boulder began to slip and the animals cried out in despair at finding themselves dragged down the hill, it was always Boxer who strained himself against the rope and brought the boulder to a stop. To see him toiling up the slope inch by inch, his breath coming fast, the tips of his hoofs clawing at the ground, and his great sides matted with sweat, filled everyone with admiration."
"The animals were not badly off throughout that summer, in spite of the hardness of their work. If they had no more food than they had in Jones's day, at least they did not have less. The advantage of only having to feed themselves, and not having to support five extravagant human beings as well, was so great that it would have taken a lot of failures to outweigh it."
"Yes, there it lay, thr fruit of all their struggles, levelled to its foundations, the stones they had broken and carried so laboriously scattered all around. Unable at first to speak, they stood gazing mournfully at the litter of fallen stone."
"By the autumn the animals were tired but happy. They had had a hard year, and after the sale of part of the hay and corn, the stores of food for the winter were none too plentiful, but the windmill compensated for everything. It was almost half built now. After the harvest there was a stretch fo clear dry weather, and the animals toiled harder than ever, thinking it well worth while to plod to and fro all day with blocks of stone if by doing so they could raise the walls another foot."
