Question

how does orwell use satire to achieve his purpose in this passage?
by having clover neigh repeatedly to show a
reversal in roles
by having the pigs walk awkwardly on two legs
as an imitation of humans
by having the animals return to the buildings
to show a change in fortune
by having the dogs frolic around napoleon to
make fun of the pigs

Explanation:

In Orwell's work (e.g., Animal Farm), satire is used to critique human behavior/ideology. Pigs walking on two legs imitates humans, mocking how the pigs (representing ruling class) adopt human - like (corrupt) behavior, which is a key satirical element. The other options: Clover neighing repeatedly doesn't relate to role reversal satire; animals returning to buildings isn't a main satirical device here; dogs frolicking around Napoleon doesn't mock pigs in a satirical way related to the purpose.

Answer:

B. by having the pigs walk awkwardly on two legs as an imitation of humans
