Stars

This miniscule amount of matter, spread over almost infinite distances, acts like a curtain obscuring the stars that lie behind. If it were not for this material we would see no dark patches in the sky at night: the sky would be entirely covered with stars.

The two parts in boldface play what roles in the argument above?

BF 1 : The distance between stars have spaces and spaces is filled with some material.
BF 2 : sky would be full of stars if the spaces between stars were not filled with some material.

Paraphrase : the author presents a fact in bf 1 and in bf2 tells us what would happen if the fact in b1 is not true.

A. The first is a suggestion that the author wishes to dispute. The second is hypothesis that the author wishes to explain.
Incorrect : bf 1 is NOT a suggestion. Eliminated.

B. The first is the main point the author wishes to make. The second is a hypothetical result of accepting that point.
Incorrect : The author has only stated a fact in bf1. He does not wish to make any point here.

C. The first is a fact that the author thinks is important in explaining a certain phenomenon. The second is a result that the author would expect if that fact were not true.
Correct : This correctly restates our paraphrase above.

D. The first is a speculation that the author wishes to justify. The second is a consequence that would result if that speculation is not true.
Incorrect : bf1 is certainly not a speculation.

E. The first is an established fact that the author wishes to explain. The second is a consequence of accepting this fact.
Incorrect : bf 2 is not a consequence of accepting the fact stated in bf 1.
