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_____ .
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.
B. the number of young adults who do regular volunteer work is on the increase
C. the feelings of well-being 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.
A和C搞不清楚
题目是不是让找一个不是volunteer的理由？

我觉得可以这么说吧.
that statistic would be what we would expect even if volunteering does not boost longevity
即使志愿工作不能延长使命,但是

可是答案是A，理解不了

文章说了：帮人会让脑子产生endorphins，产生的endorphins可能让人长寿。调查说做义工的人毕不做的人平均活得更长。
结论是：但这调查数据可能得到义工不会让人长寿。
sorry 刚翻译的不够精准，题目说，就算义工不增寿，那个统计结果也和我们期待的一样。
找一个理由。

B. 说的是做义工人的数量，这个没意义，和长寿与否没关系
C. 说的是endorphins的作用原理，这个也对结论的长寿问题无帮助
D. 说的是做义工很难坚持，这个和长寿不长寿也没关系
E. 说的是做义工反而成了一些人的生活压力来源，压力也长寿的关系也不明确

A. 说的是做义工的人里，女性比男性更容易长寿，这个至少还说了长寿，而且说了男性可能还短命了……
要说正式推断是这样：女性更男性喜欢做义工，女性比男性更长寿，所以做义工的好像更长寿了。

所以，不选A没别的可选了……

不太理解了,不过后来看了下C是MASK THE SYMPTOMS,的确有问题
尤其是提干最后的EVEN IF VOLUNTEER DOES NOT BOOST LONGEVITY

马上楼上的解释下最后一句话,

但这调查数据可能得到义工不会让人长寿?

sorry 刚翻译的不够精准，题目说，就算义工不增寿，那个统计结果也和我们期待的一样。

A要说正式推断是这样：女性比男性更喜欢做义工，女性比男性更长寿，所以做义工的好像更长寿了。这就说明就算义工不增寿，我们解释统计结果了……符合结论

呵呵,这个题目的确是个有意思的题目,符合ETS特殊题目的思路

mickleon

楼上老兄，这个题目很特殊吗？
能帮忙elaborate一下ETS特殊题目的思路特征吗？

Rebeldom

在我眼里,做不来就特殊
你分析手法就是用了最直接的相关法则了么
相关性,概率性是GMAT王道
