Let’s try completing the sentence in our own words.
It makes sense that statistics showing many cases of respiratory ailments among
construction workers would help prove the connection between asbestos exposure
and lung cancer. Now let’s scan the answer choices for our ideas. Choices (B) and
(D) complete the first blank much as we just did (incidence means “rate of
occurrence”). But choice (A) also completes the second blank much the same as we
did. So let’s focus on these three choices.
Although the second completion in choice (A) works well in the sentence by itself,
when put together with the first part, you have a pointless sentence telling us
that a reason proves a reason. So you can eliminate choice (A). As for choice (B),
to say that something “influences a causal connection” is confusing and vague,
and so you can eliminate choice (B) on this basis. That leaves choice (D). The
word underscore means “emphasize.” This certainly wasn’t the idea we originally
had in mind for completing the second blank, but it works well. So remember:
Don’t automatically eliminate an answer choice just because it doesn’t express
your own ideas.The correct answer is (D).
