I would say that the major aspect of narrative nonfiction that I can trace in this excerpt from Theodore Dreiser's "My Brother Paul" is A) reflection.
The narrator is reflecting on his past, and thinking about who the person who truly and completely understood him was.
The correct answer is D. charity.
A colon (:) should be placed after the word charity in the sentence above. This is because you are giving the name to her charity, and therefore, a colon should be there in order to separate the sentence from the actual name. So the sentence should be:
(...) who benefit from her charity: Hannah's Gold.
