Explanation


The “Yet” that begins the second sentence indicates that Wills’ position would be supported by evidence that the newer parasites are in humans, the more harmful they are. So Wills’ position must be that more recent parasites are especially harmful, implying that “malignant” is the correct choice for the first blank. What follows “therefore” is a potential explanation for the trend that Wills expects, namely an evolution toward harmlessness, implying “benignity” for the third blank, with newer species having had “insufficient” time (second blank) to evolve toward harmlessness.
Thus, the correct answer is malignant (Choice B), insufficient (Choice E), and benignity (Choice H).

Please explain why the third blank inclines toward harmlessness? What is the clue for this?

The question had medium tag as difficulty. However, it is hard indeed.

The “Yet” that begins the second sentence indicates that Wills’ position would be supported by evidence that the newer parasites are in humans, the more harmful they are.

the clue is Yet.

Actually, the overall meaning is that parasites mute them into harmless host if stay longer inside humans. However, we do not have enough information to ascertain this with certainty. It is just another supposition.

Now is more clear ??

The key to solve TC is to catch as close as possible the meaning of the sentence as whole.

I think this question is a stretch, because how are we to know that mosquitoes evolve towards benignity, the longer they are exposed to their human hosts? At the same time, the other two choices do not work.

I think this question asks us to make quite a bit of a logical leap, maybe a bit too much!

By the way, what is OG SECOND REVISED EDITION?
