OG11-28

 Beyond the immediate cash flow crisis that the museum faces, its survival depends on if it can broaden its membership and leave its cramped quarters for a site where it can store and exhibit its more than 12,000 artifacts.

(A) if it can broaden its membership and leave

(B) whether it can broaden its membership and leave

(C) whether or not it has the capability to broaden its membership and can leave

(D) its ability for broadening its membership and leaving

(E) the ability for it to broaden its membership and leave

正确答案B。关于E选项，OG给的解释是：The ability for it to broaden is wordy,awkward,and ungrammatical. 我的问题是为什么会awkward ungrammatical呢？

另外OG11-32题也有这种类似的结构 it might have been expected for it to rise  OG的说法是not complete the idiomatic expression correctly 是不是对于for it to结构GMAC不prefer呢？
