Let's take a closer look at the difference between answer choice (B) and answer choice (E):
(B) If a TV show would be cancelled unless many people took certain actions, then everyone who feels that the show is worth preserving ought to take those actions.
(E) If a TV show would be cancelled unless many people took certain actions, then those who feel most strongly that it is worth preserving should take those actions.
So the only difference here is "everyone who feels that the show is worth preserving" vs. "those who feel most strongly that it is worth preserving."
Notice the conclusion in the stimulus states, "Thus, anyone who feels that a TV show is worth preserving ought to buy the products advertised during the show." There is no mention in the stimulus of "those who feel most strongly that it is worth preserving."
As such, (B) would be the correct answer.
Hope this helps! Please let us know if you have any other questions.
