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
KEY: E
當初選C 因為動詞 broadcast作單數
但是考慮 if 會改變句意則可排除C
E中的the three major networks each 能作複數嗎??
