Which best describes why an author might employ an allegory? a.) to develop complex and lifelike characters b.) to offer insight to the social structure of a society c.) to praise some personality traits and scorn others d.) to demonstrate the complexity of the justice system

The correct answer is b) to offer insight to the social structure of a society.

The allegory might be used by the authors as a rhetorical device to introduce more abstract topics into their writings. These abstract topics usually illustrate a social or political atmosphere related with the authors and their life experiences. Then, by the use of metaphors, symbolism and analogies, authors introduce deeper social conflicts into their pieces.

my best guess would be: d allusion

makes the most sense
