GMAT Question of the Day – 15/1/2021

ANSWER SELECTION

(A) numbers of annual convention attendees grew by more than a 200 percent increase

(B) numbers of annual convention attendees grew more than 200 percent

(C) numbers of annual convention attendees were raised by more than 200 percent

(D) number of annual convention attendees increased by more than 200 percent (THIS IS CORRECT!)

(E) number of annual convention attendees was raised by more than a 200 percent increase

ANSWER EXPLANATION

Since the count of annual convention attendees would be a single number, the sentence should use number, not “numbers.” There’s also a redundancy error, since “grew” already implies an “increase.” Due to these errors, (A) can be eliminated.

A vertical scan reveals that (B) and (C) also incorrectly use “numbers” and can be eliminated.

Next, examine (D) and (E). (E) unnecessarily introduces the passive voice and still contains the redundant “raised” and “increase.” (D), however, correctly uses the singular “number,” uses the active voice, and contains no redundancy. (D) is therefore correct.
