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

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
答案是E，不是很理解，虽然D有不好的地方，例如falling。不过感觉E的表达也有问题，强调的中心有转移吧
先谢谢啦，哪位能帮忙分析一下哈？
