Read the passage from Animal Farm. In the end they finished the harvest in two days' less time than it had usually taken Jones and his men. Moreover, it was the biggest harvest that the farm had ever seen. There was no wastage whatever; the hens and ducks with their sharp eyes had gathered up the very last stalk. And not an animal on the farm had stolen so much as a mouthful. What is the central idea of this passage? The animals are scared to steal. The animals work efficiently in harmony. The animals wish they had humans to help them. The animals do not have time to rest or eat meals

The central idea of this passage is (B). The animals work efficiently in harmony.

Explanation:

A. The animals are scared to steal.

There was no stealing involved in the passage.

B. The animals work efficiently in harmony.

The passage mainly talked about the "biggest harvest that the farm had ever seen" with the animals' hard work in unification.

C. The animals wish they had humans to help them.

Animals can't wish humans help them. That's impossible for animals to "wish".

D. The animals do not have time to rest or eat meals.

Not having time to rest or eat meals isn't the whole idea of this passage whatsoever. I also don't see anything that involved with animals eating food. Why is it a thing for animals to not have enough time to rest or eat meals?–– that makes no sense. Only humans are capable of having not enough time to rest or eat meals–– they have the power to do so.
