Explanation
This question requires us to visit lines 20-24 and
determine what kind of "case" is described there. The lines refer to
now-familiar excessive administration of antibiotics. But we are asked to
identify a benefit of such a case--a
case of overmedication that may be harmful. That might be hard to imagine, so
we can simply apply ourselves to the answer choices and look for one that is
consistent with the passage. Choice (A) describes a negative outcome, so it's
out. Choice (D) is inaccurate, because the author has identified this case as
especially problematic, so it's out. Choice (B) makes a claim that has no
support in the passage, and which is implausible, to boot. Choice (C) must be true, because it's a recurring
theme of the passage that patients demand these treatments and that their wants
are less-informed. Choice (E) describes the spending of public funds, which has
not been equated with the case of harmful medication, so it's out.
The correct answer is (C).
