Q13:

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?

1. Marriage tends to cause people to engage less regularly in sports that involve risk of bodily harm.
2. 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.
3. 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.
4. 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.
5. Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry.

answer is E

文中比较的对象应该是又坏习惯的人中结了婚的和没有结婚的人比较吧？

d说结了婚的人会改掉坏习惯，而且不会再养成那些坏习惯，所以更健康，所以支持结论

e说的是没有坏习惯的人，不是文章讨论的范围吧？

另外b说，有坏习惯的人中，结婚的比那些没结婚的人更容易改掉坏习惯，应该是支持文章结论吧？为什么不选呢？

我个人觉得B和D似乎表达同一个意思,但是我觉得B更合适,因为文章结论要比的就是那

些结婚和不结婚的人,是不B更合适呢?
