19. 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）为什么（C) 不对呢，觉得各个方面都没有问题呀！坦率地讲倒觉得（E）有点罗嗦。NN们帮助一下吧，谢谢！

C is misleading in that "if not" may mean "television can be not superficial". Or, to be easier to understand, "if" may mean "if only".

Thanks tianwan, but still a little confused. Why the original sentence can be what (C) expresses. Among all the five choices, is there any one that set the tone of the meaning, is it (A)? But what if there is logic error in (A). Help please!

非常感谢tianwan, 让我再好好想一想。不知道你是不是已经考完了，如果有一样东西或资料你现在没有，但一旦有了以后你觉得会特别有帮助（真提除外），你告诉我我会尽量帮你搞到。
