The answers are:
-“The animals had assumed as a matter of course that these would be shared out equally.”
-“All the windfalls were to be collected . . . for the use of the pigs.”
-“All the pigs were in full agreement on this point, even Snowball and Napoleon.”
In the first statement, the word “animals” refers to the population, the mass, who naively assumes they shall be treated equally. In the other two statements, the pigs are the animals chosen to represent the leaders who, in turn, are sure to deserve more and better than the rest of the population.
The critique we can take from this work, Animal Farm, is the fact that the real power comes – or should come - from the mass, the population. Leaders are chosen – by the population - not to be treated differently or specially, but to serve the interests of everyone.
In Animal Farm, the society described using animals is a satire of communism in the Soviet Union. Communism claims to work for the people, to guarantee equality, also accusing Capitalism of only promoting inequality. The author, George Orwell, criticizes how communist leaders easily walk away from that ideal when they find themselves superior and more deserving than the rest of the country.
