An international study recently examined the effects of second hand smoke on health. surprisingly, although the dosages of harmful chemicals form second hand smoke are so small that their effect should be negligible, the study found that nonsmoking souses of smokers displayed an incidence of heart disease that was significantly greater than that of nonsmokers who were not as regularly exposed to second hand smoke.
Each of the following if true could contribute to an explanation of the unexpectedly high incidence of heart disease in smoker's spouses EXCEPT:
A. A disproportionately high number of people married to smokers are among the older segment of the married population, a group that inherently has a higher than average risk of heart disease
B. on average, more alcohol and coffee both of which have been linked to heart disease, are consumed in the homes of smokers than in the homes of nonsmokers.
C. A disproportionately high number of smokers are married to other smokers and the risk of heart disease increases in proportion to the number of smokers living in a household.
D. Smokers generally tend to live in higher stress environments than do non smokers and stress is a factor associated with above average incidence of heart disease.
E.A disproportionately high number of smokers live in areas with a high level of industrial pollutants, which have been shown to be a factor in increased risk of heart disease
OA is C, IMO D
