Answer:
Reversal is used to show how Clover, representing the people, has changed ideals.
Explanation:
In writing, reversal is usually a moment when something can be seen from a different perspective and form a different opinion than the one readers or characters had in the beginning.
In Animal Farm, a novella by George Orwell, the animals represent the people. They kick out the human who owned the farm where they lived and decide to establish a society where all animals are equal and free. Such ideals, however, are destroyed when the pigs, the most intelligent animals, realize that they enjoy being in power and begin to opress the other animals.
The paragraph we are analyzing here shows precisely that: Clover is disappointed by the cruelty of the system they have created. Even though she still believes them to be better off without the humans, her ideals concerning the animal society have changed.
