How does the dialogue in paragraphs 78-94 develop the plot of the story?

A
It reveals that Mr. White’s wish has been granted but not in the way they expected.
B
It shows that the visitor is uncomfortable with what he has to say, even though he is bringing a gift.
C
It suggests that Mrs. White is concerned about her husband and takes steps to help him deal with the news he’s received.
D
It shows the sergeant-major reappearing in the story and causing more problems within the family.

the answer is:  

he is voicing feelings shared by all humans regardless of race.

in paul laurence dunbar's poem "we wear the mask," he replicates the words mask and we to emphasize how people in general -not just black americans- hide their true feelings. he suggests the masks cover people's faces and eyes, which are the main parts that display their emotions. he also thinks people's pain conceal behind those masks, so that they cannot see reality and nobody is able to see one another's sorrow.
