I believe the answer is true
hey there! I think it's D. (been awhile since i've read edgar allan poe.
It describes the setting of the excerpt because it describing the dust and season.
It is not the climax because it isn’t the most intense part of the story.
It is not the conflict because it’s a flashback of the narrator’s hometown. However the conflict could seem that it is very dry, but how would the protagonist solve that problem. Drink some water?
Lastly, It is not describing the characters of the excerpt because the main focus is on the hometown of the narrator.
It depends, but splash is a word that could be used :D Hope this helps!
