According to a study of more than 50,000 Norwegian smokers, smokers who reduced their nicotine intake from cigarettes, even by up to 50 percent, did not achieve significant health benefits. The mortality rate for those who cut back on cigarettes was not lower than that for heavier smokers; moreover, the rate of cardiovascular disease was similar across all subsets of smokers in the study. As a result, the sponsors of the study claim that reducing nicotine intake does not improve one's health.

Which of the following, if true, most seriously jeopardizes the findings of the study described above?

A. The majority of study participants minimized their nicotine withdrawal symptoms through the use of skin patches and chewing gum that provide nicotine to the body.

B. Many of the study’s participants periodically dined in restaurants in which smoking was permitted.

C. The study’s participants started smoking at different ages and had varied initial nicotine intake.

D. Quitting smoking entirely results in a marked reduction in the ill effects of smoking.

E. Men and women who smoked pipes and cigars were excluded from the study.

I picked B. Seems like the ans is A.
Please voice your opinion?

"A" should be the correct answer..

The conclusion: "the sponsors of the study claim that reducing nicotine intake does not improve one's health."

Now "A" states that the smokers adapted other means of nicotine intake that donot show symptoms of nicotine intake..Now during the survey these smokers will be treated as if they have quit smoking/ nicotine intake thereby they should show the signs of health improvement but infact they have continued nicotine intake and nobody will make it that they are taking nicotine intake becoz the symptoms are supressed though the body is still taking nicotine intake thereby not showing health improvement..

hence the conclusion is weakened..
