请教一道gwd

T-4-Q22
            

Unlike mainstream American businesses, more than half of which fail, the failure rate for businesses in the Amish community hovers around 5 percent.
            

D\E

A.      Unlike mainstream American businesses, more than half of which fail

B.       Unlike mainstream American businesses, in which the failure rate is more than half

C.      Unlike mainstream American businesses, where more than half of them fail

D.      While the rate of mainstream American businesses failing is more than half

E.       While more than half of mainstream American businesses fail

这道题我选的是d，答案是e。我认为d选项前后很对称工整，没有问题，倒是e接的不舒服。请牛牛指教！

我觉得while the failure rate of mainstream American business is 。。。这样才工整和后半句对应吧~

而且用了while 就暗示说不用再去考虑主语的比较对称性问题了~，所以用了主动语态不是更优吗~？呵呵~个人看法~

就是说fail的名词是failure，这里不该用failing。
