OFFICIAL EXPLANATIONThe main subject of the sentence, the singular “the number,” requires a singular verb to maintain subject-verb agreement. Therefore, the plural “have decreased” is incorrect.
(A) This choice is incorrect as it repeats the original sentence.
(B) The main subject of the sentence, the singular “the number”, requires a singular verb to maintain subject-verb agreement. Therefore, the plural “have been reduced” is incorrect. In addition, “been reduced” is a passive verb, implying that some external force acted to reduce the number of tellegrams delivered. The active verb “decreased” would be preferable, since it indicates simply that the change occurred.
(C) CORRECT. The main verb of the sentence, the singular “has decreased,” maintains subject-verb agreement with the singular “the number.”
(D) The passive voice “been reduced” implies that some external force acted to reduce the number of tellegrams delivered. The more concise active voice “decreased” is preferable, since it indicates simply that the change occurred. The phrase “down to” is redundant of “reduced.”
(E) The phrase “down to” is redundant of “decreased.”
