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:

the answer is E, what is wrong with B?

年轻时就结婚的男女比没结过婚的人长寿。但这并不说明结婚使人长寿，因为和同龄人相比，打算结婚的人没有很多会让人折寿的坏习惯，尤其是吸烟和喝酒。

结论是结婚没有使人长寿

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.结了婚的有坏习惯的人比没结婚的有坏习惯的人更可能改掉坏习惯，这不是说结婚让人改掉坏习惯，进而使人长寿吗，是支持了结论反对的观点，既削弱结论。
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.在不吸烟喝酒的年轻人里，不结婚的和结婚的活得一样长。这正好说明是因为不吸烟不喝酒而活得长的，而不是因为结婚活得长，支持结论。
