The correct answers are:
1. Corruption of power is B. Napoleon murders animals falsely accused of treason.
Napoleon’s excess of power, control and paranoia leads him to murder any animal in the farm who opposes to his plans and decisions. This is a clear example of the corruption of power, as he becomes a dictator going against the principles of the rebellion.
2. Social-class hierarchy is D. The pigs sleep in beds while the other animals do not.
As the dictatorship of Napoleon and the pigs advances, the farm undergoes several changes from the beginning of the rebellion. One of these is the return of the social-class hierarchy, in which the pigs are at the top, benefitting themselves from some luxuries that used to be forbidden.
3. Working-class loyalty is C. Napoleon is always right.
Squealer convinces the other animals that their leader is always right, even if Napoleon seems not to take the best decisions for the progress of the farm. In order to succeed in ensuring the animals’ loyalty, Squealer creates the motto “Napoleon is always right.”
4. Manipulation of language is A. Lies are circulated about Snowball.
Squealer, under the order of Napoleon, distorts facts and the words of Snowball to make the animals think that he is the major enemy of Animal Farm. When the animals remember Snowball teachings, Squealer changes the facts to the opposite to turn him into a villain.
