Because Halleyâ€™s comet changes orbit slightly during the seventy-six-year interval between passing close to Earth, it may veer onto a collision course with a planet sometime in the distant future.
(A) between passing
(B) of passing
(C) between its passes
(D) of its passes
(E) as it passes
MA could you please underline the SC's as they appear on the GMAT. Makes it easier on the eyes. Thanks
Here is my explanation:
A, C are eliminated because of "between". Use between when you are choosing from 2 things. The author isnt trying to choose "passing" and something else [not passing, maybe??].
The preposition "as" conveys the author's meaning.

close to Earth, <IC>
Dunno what is wrong with "B" and "D" gramatically. Except that when you say the following phrase "During the seventy-six year interval" AC "B" or "D" sound very awkard. But E makes sense of what the author is trying to say as the color code shows.
Any care to explain why B and D are grammtically wrong? I see a possessive form of the pronoun in D........
