标题: 求教gwd 5-13 waiting on line

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?

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

the answer is D, i have been hesitating between B and D.which evidence can be offered to rule option B out ???

thanks thousand!

为什么,快被逻辑逼疯了~~~

原文的argument是，婚姻并不能使人们live longer，因为那些即将结婚的年轻人（那就是说，在结婚前）有比较少的不健康生活习惯

B，结了婚的人更容易戒掉不健康的习惯
D，在结婚前戒掉的坏习惯，结了婚后不会再染上

B对原argument是weaken而不是加强，因为B的意思是结了婚后，人们更容易戒掉不健康的习惯，这个和原文argument 婚姻不能使人长寿相反，是削弱甚至是否定原argument

D，结了婚后怀习惯不会再染上，再加上原本说的他们在结婚前已经戒掉怀习惯，说明婚姻对长寿真的没有影响，因为他们婚前戒掉了坏习惯，婚后不会再染上，所以决定他们长寿的因素在结婚前已经确定了，marriage has no effect on that.

有些明白了,B的确是削弱了argument,因为强调了结婚对人的影响.

D 中的most of those who give up an unhealthy habit after marriage do not resume the habit later in life.我怎么理解为结婚后改掉的习惯不会再染上呢???

对D 还是有点糊涂呢

谢谢指教＾－＾

怎么觉得E更好呢

D感觉是在加强marriage。

E说那些没有坏习惯的，不管结不结婚都活得一样长。恰恰否定了marriage causes people to live longer，而且如果和提干联系在一起更加强了unhealthy habit是造成寿命长短差别的原因。

对，E是对的，D我当时没有看清楚，也没有仔细看各个选项，因为lz问得是B和D

翻查以前的讨论帖子，当时讨论的结论也是E是正确的
