Thanks for posting,
robinzhang7!
I think the primary thing that's throwing you off here is that you're missing a critical distinction between actual advertisements (and reader's responses to them) and the idea of mentioning products
in the articles (and reader's responses to
that practice). The editor isn't talking about actual advertisements at all! He's only talking about what will happen if they start loading up the articles with product placements!
As a result, the editor's argument depends on some assumptions about how readers will respond to 'product placements in articles', but it does not depend on any assumption about how readers respond to advertisements themselves.
I'd break this argument down from the top, but
nicholasasquith did such an absolutely killer job above, I'm just going to steal his (bolding mine):
nicholasasquith Wrote:Magazine editor says:
(P) Our magazine needs loyal readership to be effective at advertising
(P) We'll lose loyal readership if our readers suspect our integrity has been compromised by pandering to advertisers.
(C) Promoting products in our articles will actually hurt the advertisers
The gap I see here is that he's assuming ads in articles will cause readers to be suspicious of the magazines editorial integrity. It's a reasonable assumption, but nevertheless, an assumption.
Ad-sales guy says:
(P) Readers can recognize that advertisements are not articles.
(SC) The way readers respond to ads is therefore, not dependent on the magazine's editorial integrity.
(C) You're underestimating the readers' sophistication.
The editor's point is essentially that once readers see a lot of product placement in articles, they'll just stop reading the magazine, and then they won't even see the advertisements. The director may well be right that the readers could still respond favorably to the ads, but if they aren't reading the magazine anymore, then it doesn't really matter!
As a result, his argument doesn't depend on any assumptions whatsoever about how readers respond to ads that they see, making
(D) fit perfectly.
Let's take a look at each wrong answer choice:
(A) The only factor the editor points out as potentially affecting an advertisement's effectiveness is the existence of a loyal readership - in other words, we have to have readers in the first place for the ads to be effective. Not only is this pretty reasonable, it's also one of the editor's premises, not an assumption. Additionally, the director does not attempt to undermine this point!
(B) The director certainly claims that the readers are sophisticated enough to distinguish ad from article, but the editor never suggested they couldn't.
(C) This answer choice accurately reflects what the editor's argument is about: advertisers influencing articles. However, the director's argument doesn't touch on this at all.
(E) The editor has no view about how readers respond to advertisements - his entire argument is about how readers respond to product placement in articles!
Please let me know if that helped clear a few things up!
