Question

Which statement best explains how paragraph 2 makes the essay clearer?

Answer 1

Answer: B. It gives background for the more practical information on  volcanoes that follows.

Explanation:

There is no passage attached nor referenced as such I could not find it. The above option however, should be the answer.

When a section of a passage gives background information about what is to follow, it lays the groundwork and gives the reader context about what is being described thereby making the essay clearer. Option B is therefore the most probable answer.
