一道从来没弄懂过的逻辑题……

GWD5-13
It is true of both men and women that those who marry as young adults live longer than those who never marry.  This dose not show that marriage causes people to live longer, since, as compared with other people of the same age, young adults who are about to get married have fewer of the unhealthy habits that can cause a person to have a shorter life, most notably smoking and immoderate drinking of alcohol.

Which of the following, if true, most strengthens the argument above?

A.    Marriage tends to cause people to engage less regularly in sports that involve risk of bodily harm.
B.    A married person who has an unhealthy habit is more likely to give up that habit than a person with the same habit who is unmarried.
C.    A person who smokes is much more likely than a nonsmoker to marry a person who smokes at the time of marriage, and the same is true for people who drink alcohol immoderately.
D.    Among people who marry as young adults, most of those who give up an unhealthy habit after marriage do not resume the habit later in life.
E.    Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry.

这道题说的是结婚和寿命长短的关系，我记得新东方小蓝上有一道是夫妻和睦与数字的关系。这两道题很想建议楼主对比着看。

这题的正确答案应该是E
原文：将要结婚的人很少有不健康习惯
结论：不是婚姻本身导致寿命长 （是将要结婚这群人的原有特性即少有不健康习惯导致寿命长）
E 选项  结婚和不结婚的人，当他们同样都少有不健康习惯时 ，寿命一样长  即少有不健康习惯导致寿命长
其他选项都没强调这一点 所以不对

我之前也没弄懂，
我觉得这题的结论是“This dose not show that marriage causes people to live longer”
只有E有这个意思
其它选项都支持结婚对寿命有好的作用
