Explanation

Reading the question: In this question we have a plan. The government will distribute brochures to fight counterfeiting. As we've seen before, a plan is like an argument with the main idea, "These actions are going to have this effect." We see that we want to choose an answer that strengthens the plan. To strengthen, we first weaken.

Creating a filter: To weaken a "plan" argument, imagine a situation in which all of the steps of the plan are completely or mostly fulfilled, but somehow the effect doesn't occur. We imagine that the brochures are printed and a brochure lands in the hands of every seller and consumer. We can imagine, even further, that everyone actually reads the brochure (which is imagining a lot). But it's easy to imagine that the plan won't have its effect even then. Maybe, even if everyone gets and reads a brochure; people won't care. The flaw in the argument is that maybe people won't care. So a great way to strengthen the argument would be to establish that people will care.

Applying the filter: Choice (C) matches our prediction. Choices (A), (B), and (D) have little to do with whether the plan will work. Choice (E) might weaken the argument, as more fleeting relationships might make it more difficult to target people to give the brochure to and might make it more difficult to report vendors. So (E) is out, and we're left with only (C).

Logical proof: we can confirm that (C) is correct either by the negation test or by analysis by cases. If sellers were unbelievably passionate to defend movie artists' rights, that attitude would indeed strengthen the plan. And if, on the other hand, they didn't care about defending rights--or wanted to defraud artists--then the plan would face a major hurdle. Choice (C) is indeed material to the plan. The correct answer is (C).
