Question

PART A: In paragraph 4, how does the author's use of "crumples,"

Answer 1

Answer: B. by helping the reader to imagine the violent movement  associated with convergent boundaries

Explanation:

The words "crumples,"  "buckles," "crashed," and "mash-up" are all descriptive words that when read, help the reader to visualize the subjects being acted on by these verbs.

In this scenario therefore, the author put these words so that the reader can imagine just how violent it can get when convergent boundaries move and meet without the reader needing to actually see it because these words when used on objects, serve to describe a certain level of destruction.
