Hi
I have taken the GMAT prep test today and was stuck with options D and E.
Though the post is quite old and i have gone through the explanations which states that three actions
to single out, begin and impose are required to be parallel.
But I read the sentence and understood that "and separated by commas" doesn't this makes the two parts of the sentences as independent clauses.
So the parallelism will be applicable to first independent clause only.
Please clarify.
