Why are the elements of an autobiographical narrative similar to those of a short story?
a. because the form its about stories from real events in a writer's life
b. because most writing forms include narratives
c. because it includes causes and effects
d. because the form its nonfiction

I believe the correct answer is B. Because most writing forms include narratives.

The first and last options aren't correct because an autobiographical narrative depicts real events from the writer's life, whereas a short story is fictional, which means the events and characters aren't real (and it doesn't have to be written in the 1st person).

The third option can be correct, but not in every case. Some of the best short stories don't include causes and effects. Actually, the causal relations are often concealed, and require a specific interpretation to explain them.

However, there is a narrative in both these forms. It means that they have a plot - introduction, climax, resolution (although they don't need to happen in a chronological order).

He does this as a prank because he loves playing tricks on mortals and and fairies alike.
