In Norway, however, where there has been a ban on tobacco advertising since 1975, smoking is at least as prevalent among teenagers as it is in countries that do not ban such advertising. Which of the following statements draws the most reliable conclusion from the information above? (A) Tobacco advertising cannot be the only factor that affects the prevalence of smoking among teenagers. (B) Advertising does not play a role in causing teenagers to start or continue smoking. (C) Banning tobacco advertising does not reduce the consumption of tobacco. (D) More teen-agers smoke if they are not exposed to tobacco advertising than if they are. (E) Most teen-agers who smoked in 1975 did not stop when the ban on tobacco advertising was implemented. OA: A Need free GMAT or MBA advice from an expert?

OA: A Boiled way down: In Norway teenage smoking is as prevalent as it is in other countries, despite a long-time advertising ban. Clearly, if these kids began smoking in the absence of advertising, there had to have been a factor other than advertising that prompted them to start.

Which of the following statements draws the most reliable conclusion from the information above?

(A) Tobacco advertising cannot be the only factor that affects the prevalence of smoking among teenagers.
(B) Advertising does not play a role in causing teenagers to start or continue smoking.
(C) Banning tobacco advertising does not reduce the consumption of tobacco.
(D) More teen-agers smoke if they are not exposed to tobacco advertising than if they are.
(E) Most teen-agers who smoked in 1975 did not stop when the ban on tobacco advertising was implemented.

OA: A
Put another way, if advertising were the only factor that impacted the prevalence of smoking in teenagers, it wouldn't make any sense for smoking rates to be no different in a country that banned advertising.

However, here's a backup strategy to consider: Negate each answer choice. If the NEGATED answer choice contradict the given information, then it is the correct answer. So A, when negated, becomes Tobacco advertising IS the only factor that affects the prevalence of smoking among teenagers. This negated answer choice makes no sense since we're told that there's no tobacco advertising in Norway and the teenagers there smoke just as much as teenagers in countries that have tobacco advertising.

Thus, negation in this case doesn't seem to hit the PREMISE in the ARGUMENT . Why it will be wrong ? An inference is a statement that MUST BE TRUE, given the information in the passage. One approach is to apply the NEGATION TEST. When the correct answer choice is negated, the passage will be contradicted. Passage: In Norway, where there has been a ban on tobacco advertising since 1975, smoking is at least as prevalent among teenagers as it is in countries that do not ban such advertising. In other words, countries with tobacco advertising do NOT have more teenage smoking than Norway, which bans tobacco advertising. A, negated: Tobacco advertising is the only factor that affects the prevalence of smoking among teenagers. Implication: Countries with tobacco advertising MUST HAVE MORE teenage smoking than countries without tobacco advertising, since tobacco advertising is the ONLY factor that affects the prevalence of teenage smoking. The negation of A contradicts the portion in red and thus the passage. Since the negation of A contradicts the passage, A is a valid inference: a statement that MUST BE TRUE, given the information in the passage. The correct answer is A. _________________ Mitch Hunt GMAT Private Tutor GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "Thank" icon.

Let's take that example and see if it can hold, logically. Say that advertising is the only factor that influences teenage smoking rates.

Could it be true that smoking ads were the only factor that contributed to smoking rates? Well, in 2017, the 40 smoking teenagers from 1974 are all middle-aged. So it's not as though the advertising ban dropped the number of smokers in this population from 40 to 20. Rather, we've got 40 middle-aged smokers (we'll say that no one was able to quit for simplicity's sake) and 20 new teenage smokers. How could smoking ads be the only determining factor for those 20 new smokers if the ads were banned before they were born? So in this scenario there has to be some other variable prompting those 20 smokers to begin smoking. Maybe it was peer pressure. Maybe it was the subconscious influence of movie scenes. Who knows? Ads might have been one factor for some of the 40 smokers in 1974. And the absence of ads might help explain why there aren't more smokers in 2017. But they cannot, logically, be the only factor that influences smoking rates. _________________ Veritas Prep | GMAT Instructor Veritas Prep Reviews Save$100 off any live Veritas Prep GMAT Course

I think, this time I got you -- the KEY here is : "How could smoking ads be the only determining factor for those 20 new smokers if the ads were banned before they were born?". Right ?

Essentially, it means that if if "tobacco advertising" is the the ONLY determinant/factor as far as the prevalence of smoking among teenagers is concerned, then in absence of this "tobacco advertising" how this new group of teenagers are taking up smoking in Norway -- so, that means there must be some other factor/aspect influencing smoking habits among teenagers.

Did I get you right ?

Since banning ads of tobacco did not reduce consumption among teens, we can say that advertising is not the only factor which can impact smokers. There must be other relevant reasons as well.
