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

答案是B。

这题还是挺简单的，所以CD上貌似还没人问过的样子……

但是看了答案我有点点疑惑，希望NN们解答一下，thxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx！

解释是这样的：
Logical predication;  Diction;   Verb form

The sentence compares the number of apples produced today with the number of apples produced in 1910. The 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. The two elements being compared must be grammatically parallel. The same amount... produces is paralleled by as it did (produce understood). The subjects amount and //are parallel, as are the verbs produces and did (produce).

A     The 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.

标红字的部分是我特别不明白的，我觉得应该是用 twice as many as 才对

还有第二个问题，就是B项中的 apples 为什么放在那个位置，B项能不能改成 apples twice as many as it did?

谢谢NN！！！
