Hi @bdeleon30, thanks for your post. Yes: the correct answer choice is framed as the contrapositive of the given premise.

Let's look at it carefully. The premise is: If a man never reads, he lives only once."

"If" introduces a sufficient condition; the other part of the statement is the necessary condition. Thus, the positive diagram of this statement is:

not R ==> LO1
(If never read, then live only once)

The contrapositive consists of reversing and negating both parts of this statement, as follows:
not LO1 ==> R

This is answer choice (A). Hope this helps! Please let us know if you have any additional questions.
