og11th-4没问过的一个语法点

4.       A survey by the National Council of Churches showed that in 1986 there were 20,736 female ministers, almost 9 percent of the nation's de twice as much as 1977.

(A)        twice as much as 1977

(B)        twice as many as 1977

(C)       double what it was in 1977

(D)       double the figure for 1977

(E)        a number double that of 1977's

e向中number指代不清，为什么d中的figure就可以亚

同感。不过错误选项嘛，无法深究，OG的官方说辞是：awkward(好像就是错误的委婉说法似的）。OG推荐的as many as in 1997偶也觉得挺别扭的，好像as many as that in 1997更完整一些，阁下一下如何？

(E)a number double that of 1977's

"that of 1991's" is wrong. Either "a number doubled 1997's" or "a number doubled that of 1997" will be correct.   

不太清楚楼上的意思，能在解释一下吗，double是可以做形容词的亚

我还没清楚呢？偶认为D中的 the figure  指代不清 ：既可以指代20,736  也可以 指代 9；
