b. it allows chaucer to write his poem in english because he is capturing the speech of english commoners.
c. it provides chaucer with an opportunity to write about characters that represent a wide range of social classes.
d. it makes the messages of the pilgrims more persuasive because a reader in chaucer’s time would have respected them for their fervent religious beliefs.
