I was caught between A and E, but chose A
(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
On second glance, Subject verb agreement gets rid of A. Hence E is good. The statement is basically trying to give an instance of how the TV can be superficial.
A- S-V donot agree - broadcast is plural.
B - trying to compare so wrong
C - conditions apply - wrong
D - tries to deal with time -"whenever"
E - Correct - use of the conjunction "as" is trying to compare or illustrate the superficiality of TV.
Hard one for me
