Answer:
They value efficiency and accomplishment.
Step-by-step explanation:
George Orwell's allegorical novella "Animal Farm" shows the animals of 'Manor Farm' rebelling against their human masters. They did succeed and began managing their own affairs, but also under the dictatorial power of a pig named Napoleon.
The excerpt given in the text from Chapter 6 shows the animals working hard to repair the windmill. And even though the humans were looking forward to seeing the farm collapse, and to see their failure, they were also impressed about the form of unity the animals showed in building the windmill. This is evident in the line "against their will, they had developed a certain respect for the efficiency with which the animals were managing their own affairs." This shows that even the humans value the efficiency and accomplishment of the animals, even though they had expected and wanted them to fail.
