※ 引述《ilovemozart (自由、民主、法治的台灣)》之銘言：
: 請問
: A recent study found that snoring, though not common in either group, is more
: commom among smokers than among nonsmokers. On the basis of this evidence,
: the author hypothesized that smoking by itself can inducingn snoring.
: Which one of the following, if ture, casts the most doubt on the author's
: hypothesis?
smoking==>snoring
: Ans: Stress induces both snoring and smoking in certain individuals.
否定因,變成Stress==> snoring and smoking.
: 我選的是
: Most smokers do not snore.
討論的是smoking==>snoring
most smokers do not snore並不能否定兩者的因果關係
說most,那是不是存在者some smoker do snore的例子
: 我後來想想他的答案也有道理，就說snore 跟 smoking 不見得有關連，可能是一個第三
: 因素, such as stress, 所造成。
: 我想問那為什麼我選的那個不行？謝謝
