In an American childhood by Annie Dillard the following passage is an example of what writing technique

"as he ran up and down the length of the field, following the football, i ran up and down the sidelines, following him."

A) long description

b) poor verb choice

c) repetition for effect

It is C

Just so its 20 characters

c) Repetition for effect

Explanation:

The author uses repetition, which is an rhetorical device, in order to covey certain meaning, to add emphasis, unity, power and an artistic effect to the ideas of both characters doing the same (running up and down and following something) but with different aims, perhaps in order to contrast that while the male's attention was on a superficial thing, like a ball, the speaker's attention was on a real person.
