Because quitting smoking is very stressful and leads to weight gain, it is difficult to do so. The key to quitting, however, may be as simple as replacing an unhealthy activity with a healthy one. In one study, half of those attempting to quit were assigned to a smoking-cessation program alone, and the other half were assigned to the same program plus fifteen weeks of aerobic exercise. At the one month mark, none in the first group had quit, but 40 percent of those in the second group had not smoked.

Each of the following, if true, provides some support for the argument EXCEPT:

(A) Regular exercise prevents weight gain.
(B) Each group in the study included four hundred randomly selected participants.
(C) Nonsmokers accustomed to regular exercise do not gain weight when they stop exercising.
(D) Aerobic exercise can stimulate the brain's production of endorphins, which reduce tension.
(E) Of those in the second group in the study, 38 percent had not smoked at the one-year mark.

IMO C

EXCEPT:

(A) Regular exercise prevents weight gain.---addresses one of the reason and hence strengthens
(B) Each group in the study included four hundred randomly selected participants.---addresses one of the reason and hence strengthens
(C) Nonsmokers accustomed to regular exercise do not gain weight when they stop exercising.---Irrelevant
(D) Aerobic exercise can stimulate the brain's production of endorphins, which reduce tension.---addresses one of the reason and hence strengthens
(E) Of those in the second group in the study, 38 percent had not smoked at the one-year mark.---addresses one of the reason and hence strengthens, but only 2% increase but still an increase

Hi Mohitstarc, Welcome to the GMAT Club!

Did you notice it is an EXCEPT question. So the correct option choice would be the one choice that does not support the argument while all other choices would do so.

Let me know if you still feel the same.

Hi

I opted C due to following reasons:
Because quitting smoking is very stressful and leads to weight gain, it is difficult to do so. The key to quitting, however, may be as simple as replacing an unhealthy activity with a healthy one. In one study, half of those attempting to quit were assigned to a smoking-cessation program alone, and the other half were assigned to the same program plus fifteen weeks of aerobic exercise. At the one month mark, none in the first group had quit, but 40 percent of those in the second group had not smoked.

Each of the following, if true, provides some support for the argument EXCEPT:

(A) Regular exercise prevents weight gain. The key to quitting, however, may be as simple as replacing an unhealthy activity with a healthy one.

(B) Each group in the study included four hundred randomly selected participants. It gives you information about people involved in the experiment got selected on random basis for both the groups .
(C) Nonsmokers accustomed to regular exercise do not gain weight when they stop exercising. This statement is about nonsmokers weight gain. so irrelevent
(D) Aerobic exercise can stimulate the brain's production of endorphins, which reduce tension. Because quitting smoking is very stressful and leads to weight gain, it is difficult to do so.
(E) Of those in the second group in the study, 38 percent had not smoked at the one-year mark. It tells us atleast 2% people left smoking in the experiment.

Type- strengthen EXCEPT

(A) Regular exercise prevents weight gain.- incorrect; strengthens- weight gain, which is one of the factors that makes quitting smoking difficult, is prevented by regular exercise
(B) Each group in the study included four hundred randomly selected participants. - incorrect; strengthens- unbiased study--> credible results
(C) Nonsmokers accustomed to regular exercise do not gain weight when they stop exercising. - Correct - the results of nonsmokers are not relevant here.
(D) Aerobic exercise can stimulate the brain's production of endorphins, which reduce tension. - incorrect; strengthens- this deals with the stress aspect associated with quitting smoking
(E) Of those in the second group in the study, 38 percent had not smoked at the one-year mark. - incorrect; the effects of aerobic exercise were NOT temporary-- since quitting smoking is a permanent change
