The lobbyists argued that because there is no statistical evidence that breathing other people’ s tobacco smoke increases the incidence of heart disease or lung cancer in healthy nonsmokers, legislation banning smoking in workplaces cannot be justified on health grounds.
Of the following, which is the best criticism of the argument reported above?
It ignores causes of lung cancer other than smoking.
It neglects the damaging effects of smoke-filled air on nonsmokers who are not healthy.
It fails to mention the roles played by diet, exercise, and heredity in the development of heart disease.
It does not consider the possibility that nonsmokers who breathe smoke-filled air at work may become more concerned about their health.
It does not acknowledge that nonsmokers, even those who breathe smoke-filled air at work, are in general healthier than smokers.
tobacco smoke increases the incidence of heart disease or lung cancer in healthy nonsmokers, 注意这里有个qualification： in healthy nonsmokers。限定条件要么是不得不加，使reasoning更经得起质疑；要么就是无谓之举，给自己的reasoning挖坑。这里属于第二种。
