I was between C and E and ended up choosing incorrectly. I picked E because the argument says "immediate strike," and the conclusion states that "we must not strike now." Those words made me think that this was an argument about when / when not to strike. If we were supposed to just consider cost-benefit analysis, shouldn't the conclusion just say "we must not strike," period, with no timeline descriptor? Am I looking too far into this?

I put C rather than B because B seemed to talk about the quality of all books, not just the ones with intrinsic merit. The first premise that states the history of book publishers makes it sound like, in the past, publishers picked up a few books with intrinsic merit, but the rest of the books they published (different genres, children's books, whatever) were of less intrinsic value, but more profitable. So, I assumed that publishers now that don't pick up books with intrinsic value were still publishing other books of good quality but of less intrinsic value. Wouldn't the answer choice need to specify that the books of intrinsic value were of less quality, not just all books?
