In "we wear the mask" by paul laurence dunbar, the tone can be described as bitter. The tone of the poem not only can be described as bitter, I would say that author set very angry tone, he is angry about <span>having to hide begind a mask, to avoid showing people's emotions. The last lines from the poem maintain authors negative opinion towards this conflict: </span><span> "We wear the mask!" </span>
C. a theme focuses on what the story reveals about human nature.
I say C because all the other ones sounds right
