Today, because of improvements in agricultural technology, the same amount of acreage produces double the apples that it has in 1910. (A) double the apples that it has (B) twice as many apples as it did (C) as much as twice the apples it has (D) two times as many apples as there were (E) a doubling of the apples that it did Logical predication; Diction; Verb form Th e sentence compares the number of apples produced today with the number of apples produced in 1910. Th e phrase double the apples is not very exact but it could be understood to mean twice as many or as many as; the verb form has confounds the sequence of events and makes the comparison illogical. An action that occurred in 1910 requires a verb in the past tense. Th e two elements being compared must be grammatically parallel. Th e same amount … produces is paralleled by as it did (produce understood). Th e subjects amount and it are parallel, as are the verbs produces and did (produce). A Th e comparative construction as many as is needed; the verb tense has is incorrect with in 1910. B Correct. As many as is used for a countable quantity; the two elements being compared are parallel; the verb is in the past tense. C Much is used where many is required; the verb tense has is incorrect with in 1910. D Two times is wordy; there were is vague because it does not refer to amount of acreage. E A doubling of the apples is awkward and, when joined with that it did, suggests doubling the apples themselves, not the amount of apples. Th e correct answer is B.
