Although it claims to delve into political issues, television can be superficial such as when each of the three major networks broadcast exactly the same statement from a political candidate.

(A) superficial such as when each of the three major networks
(B) superficial, as can sometimes occur if all of the three major networks
(C) superficial if the three major networks all
(D) superficial whenever each of the three major networks
(E) superficial, as when the three major networks each

答案是E, 我选C

现在基本明白C是怎么错的了, 但是还对E还不很明白, as 和 when 两个词不是重复的吗?~~~

谢谢!~~~
