Smoking is a known cause of certain serious health problems, including emphysema and lung cancer. Now, an additional concern can be added to the list of maladies caused by smoking. A recent study surveyed both smokers and nonsmokers, and found that smokers are significantly more anxious and nervous than nonsmokers.
Which of the following is an assumption on which the argument rests?
1) Anxiety and nervousness can lead to serious health problems.
2) Anxiety and nervousness do not make individuals more likely to start smoking.
3) Equivalent numbers of smokers and nonsmokers were surveyed for the study.
4) Smokers are aware of the various health problems attributed to smoking, including lung cancer and emphysema.
5)Smokers who had smoked a cigarette immediately before responding to the survey were more anxious and nervous than smokers who had not smoked for several hours.
I selected the 3 as an answer but it s wrong. Acc to me study is only valid when selected groups are equal.
