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

D偷换概念了

对，选E,大家不要被D选项的前后 对应性 迷惑了。E is the best of all the five.

D  对吗？ABC不能与后面的对应，UNLIKE 后面接的不是rate，D 与后面的平行

wordance

D is just plain awkward.
No native speaker will express it that way

E明显比D简洁，D主干是 the rate is more than half，不顺

failing用的不对？
