Dear, Patrick!
I struggled with this question, I panicked
I was down to (B) and (C) and I understood the conclusion was about a relative ineffectiveness of TV Ad in attracting quality viewers compared to that favored by producers.
With this relativity issue in mind, (B) sounded too strong for a necessary assumption question.
I thought the Ad that producers favored just needed to misrepresent LESS than the TV ones. It was not necessary that they do not misrepresent at all. However, the author is concluding that one is less effective than the other, because the former has a negative quality. He must assume the other one is LESS likely to have it. And in here, “grossly” misrepresent means the Ads producers want definitely have this bad quality. so, even if it is a bit strongly worded, (B) is a needed assumption. Or are strong words (would not have) not an issue here?
On the other hand, I misunderstood (C) as saying “most of those who watched the first episode did not become loyal viewers because of TV Ad.” After negation, I thought ‘if most people who watched the first episode became loyal viewers as a result of TV ads, it means Ads were effective.’ And this seemed to weaken the argument. Although that still leaves open the possibility that Ads favored by Producers are more effective, if over half of people who tuned into the first episode became loyal viewers due to the TV ad, this seems to weaken the argument. Would this be a necessary assumption?
And also, my understanding of why the correct negation of (C) does not weaken the argument is as follows. ‘Okay, most people who watched the first episode and became loyal viewers DID tuned in as a result of the TV ad.’ We don’t know how large this group is. What if this group (those who watched the first ep. and now loyal viewers) is really small? Then, it is consistent with the conclusion that TV Ad is less effective compared to Ad favored by producers.’
Are there any flaws in my reasoning?
Thank you so much for helping me out. I really appreciate every one of your insights!
