Explanation
This question asks something we already know the answer
to: the third paragraph gives some definitive answers to the closest-relative
and living-fossil questions. Let's see which choices match that expectation.
Choice (D) is right on the money. (A) is out, because the third paragraph
introduces new information; it doesn't use information from paragraph two. (B) is out, because it doesn't introduce new topics. (C) is out,
because there is no view earlier in the passage as to whether the c-fish or the
lungfish was a closer relative, and the use of the term "living fossil" is not
really a "view" that is contradicted, so much as an idea or a description. (E) is out, similarly, because there was no view or conclusion
prior to the final paragraph.
The correct answer is (D).
