A recent study has concluded that, contrary to the claim of those trying to ban cigarette advertisements altogether, cigarette ads placed on bill boards and in magazines have little to no effect on the smoking habits of the smokers who views the ads. The study, which surveyed more than 20,000 smokers and solicited their reasons for continuing to smoke, found that practically no one in the survey felt that these advertisements influenced their decision to smoke.

The study's conclusion is based upon which of the following assumptions.

a) people do not switch cigarette brands based on their exposure to cigarette ads on bill boards and in magazines.

b) Cigarette ads on bill boards and in magazines do not encourage non smokers to take up the habit.

c) Banning cigarette ads altogether will encourage people to give up smoking

d) people are consciously aware of all reasons they choose to smoke

e) People who decide to smoke do so for rational reasons.

OA is D....

My doubt: In assumption question we can go for external details, in this argument study was based on the smokers reaction with cigarette ads placed on billboards and magazines. This argument failed to include non smokers reaction to the ads.

So as in option B we may assume that these ads do not encourage non smokers to take up the habit.( Assumption Q)

But in option D, it can be inferred that smokers are aware of the reasons of their smoking.( inference Q)

So, why option D but not B is correct.

To find the assumption behind the conclusion of the study, we need to understand the study first.
Who was studied? The study, which surveyed more than 20,000 smokers
What did the study do? and solicited their reasons for continuing to smoke
What did the study conclude? That the ads dont affect smoking behavior of [u]the smokers
who view these.
Why did the study conclude this? no one in the survey felt that these advertisements influenced their decision to smoke

okay now coming to the options:
A. Cigarette Brands? whoever talked of cigarette brands here? beyond the scope of the study at least in the context of present argument and conclusion. hence incorrect.
B. Non smokers: The study no where, to the best of our knowledge from the argumnet provided, talks of non smokers, It is a study which surveyed smokers, and talked of their reasons for continuting smoking. It didnt go to non smokers, so its conclusion is not even meant to apply to non smokers, why will it assume anything about non smokers then?
C. This is not an assumption, in fact it sounds like soething that the study would refute
D. Now the study bases its conclusion on what the smokers "felt". This means that the study assumes that the smokers know correctly and consciously what affects them or not, and thus this assumption option is correct. the study assumes that the smokers know for fact all the many fatcors which influence them, whihc might not be the case. the key word here is 'felt'
E. rationality of reasons is not of importance here, since neither smoking behavior nor advertismenets claim themselves to be on rational reasons in this argument's context.

Between B and D,

B talks about non-smokers who are not being discussed here in the argument.If we negate this it doesn't really effect the conclusion about Smokers decision.

D If Smokers are not Consciously aware of their decision,there is a high probability that their decision might be effected by the Advertisements,subconsciously.

Thus D.
