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
答案是E没问题，但是我觉得E是伴随的结果，E中的twice是不是应该是twicing？求助nn~
