-ING vs. Verb, Semicolon, Verb Tense, Pronoun Agreement
As a rule, a statement begun by a conjunction (although) is a clause and therefore must contain a verb rather than an –ING word. That eliminates (A) and (B). (C) is incorrect because the past perfect (had gained) should only be used to describe an action that came before a second action, and here that tense is used to describe an action that came after a previous action. (Action 1: The Bartered Bride was not immediately popular. Action 2: It became popular after numerous revisions.) (E) is incorrect because The Bartered Bride is singular whereas they is plural. In fact, there is no plural noun to which they could refer. That leaves (D), which correctly provides a verb (did) and makes the tense of the underlined portion consistent with the tense of the rest of the sentence.
