At the beginning of the divine comedy, dante the pilgrim believes he is in mortal danger and experiences extreme mental distress. why then does dante consider this work a comedy? your answer should be at least one hundred words.

Well, the first reason is that back then, in Dante's time, "comedy" didn't really mean funny. In this case, it meant that even though the whole story/poem is full of despair and torture and torment, it actually ends  with a happy ending. Back in Dante's era, this meant that instead of being a tragedy, this epic poem was considered a comedy. 
Consider Shakespeare's work Romeo and Juliet. It ends with the two young lovers dying, right? That is a tragedy. There is no happiness there. But at the end of Inferno, Dante the Pilgrim actually succeeds in his goals.  

This would be third person because they are using the correct pronouns that belongs to third person like he, the name, etc
