(A) doubling those reported in the 1977 survey

(B) to double the number 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

D those改称it，可以吗？？

我的理解是E的比较项是正确的,D 的比较项不正确

E比较项是:20 percent 对应the number

D的比较项是:20 percent 对应those

中心词比较的是数字,不是人,所以选E
