Which of the following most logically completes the argument?
When people engage in activities that help others, their brain releases endorphins, the brain’s natural opiates, which induce in people a feeling of well-being. It has been suggested that regular release of endorphins increases people’s longevity. And a statistic on adults who regularly engage in volunteer work helping others shows that they live longer, on average, than adults who do not volunteer. However, that statistic would be what we would expect even if volunteering does not boost longevity, because .
解释型,数据表明,自愿帮助别人的人寿命更长。结论:即使自愿活动不会使人长寿,上面的数据也会出现,因为——
A.in the communities studied, women were much more likely to do regular volunteer work than men were, and women tend to live longer than men do.我不认为A对,A还是在说it is volunteering activities that boost longevity
B.the number of young adults who do regular volunteer work is on the increase
C.the feelings of wellbeing induced by endorphins can, at least for a time, mask the symptoms of various conditions and diseases, provided the symptoms are mild.
D.it is rare for a person to keep up a regular schedule of volunteer work throughout his or her life.
E.Some people find that keeping a commitment to do regular volunteer work becomes a source of stress in their lives.
答案是A,我选的C,因为题目最后已经把volunteering可以boost longevity排除在外了作者: stevenckguo 时间: 2013-2-7 20:55
A survey on adults who regularly engage in volunteer work helping others shows that they live longer, on average, than adults who do not volunteer.
Someone suggested that this result is due to the release of a chemical. But the author thinks not. The author says that women are more likely to volunteer and women are more likely to live longer. Therefore it is more likely to see a long-living woman as a volunteer, whose volunteering work does not extend his or her life.作者: masushuang 时间: 2013-2-14 11:48
结论:However, that statistic would be what we would expect even if volunteering does not boost longevity,
可得出即便是V不能推出L,Statistic照样能得出V能推出L。
选项A,Women V 人数 > Men V 人数, 而且,Women L > Men L, 所以能推出 V 能得到 L 这个理论。
因为数据里面主要是 Women V,而刚好 Women L 更长。所以即便V得不到L,照样能从现在的这个statistic里面得到V能推出L 这样一个理论
希望我能说清楚
