  dante alighieri wrote the divine comedy, a description of a spititual journey. when he wrote it , he was in exile. in florence, dante's native city, there was a social strife, they had political turmoil, and some of the   florentine names included in the narrative may have been a way that dante used to criticize his fellow citizens.

its d! the final exam asked good luck

i think it's either 'to expose the corruption of the communists in russia', or 'to criticize animal brutality by communists in russia.'
