According to surveys by the National Institute on Drug Abuse, about 20 percent of young adults used cocaine in 1979, doubling those reported in the 1977 survey.

(A) doubling those reported in the 1977 survey

(B) to double the number the 1977 survey reported

(C) twice those the 1977 survey reported

(D) twice as much as those reported in the 1977 survey（E）

(E) twice the number reported in the 1977 survey

答案为什么是E呢? twice 是adv 能修饰后面的名词么? 多谢!!! 帮忙解释一下好么?

虽然, A的those也不太好,当double是动词,看起来总比E好.

Choice A is phrased illogically in that it says the young adults in the 1979 survey somehow doubled the people in the 1977 survey, not that the number of young adults using cocaine doubled. The infinitive to double, used unidiomatically in B, carries the sense of in order to double. Again in choice C, twice the number would be preferable to twice those(people).It is not clear in choice D whether twice as much… refers to the number of young adults using cocaine in 1979 or the amount of cocaine they used. Choice E is best for this moderately easy question.
