OG12-Q34

34, 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.

B. whether it can broaden its membership and leave

E the ability for it to broaden its membership and leave 

个位NN们，我想问下，E如果改成the ability to broaden its membership and leave对不对

还有我觉得B的逻辑上好像有点不太对，怎么是它的生存depends on 是否有能力，不是一面对两面的错误吗？
