Good question! We are trusting the passage for this one, so it looks like a Prove, but we're also trusting the answer choices ("if one also knows that"), so it looks like it might be anything. So consider the exact task. We trust the stimulus, and trust the correct answer, and that correct answer will be sufficient to prove the conclusion that's given in the question itself. Isn't that what a Justify does? Trust the original premises, add the correct answer, and the combination gives you sufficient information to prove the conclusion. Rewriting this question by putting the "conclusion" into the stimulus would have made it more clear that this was a Justify, but note that you're not drawing an inference from the stimulus, so you can see this isn't a Prove (or Disprove) family question. And the answer helps, so it must be Help. From there we just consider what we're helping - we're helping make an argument perfect. That's Justify.
