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.

答案是A ，我选了E，实在想不通为什么选A,求解释啊

我是这样想的：

A correct是因为社区研究表明，女性比男性喜欢作义工，女性又普遍比男性活得长，但并没有体现是由于做义工所以活得长的因果关系。所以即使作义工不能促进长寿，但从这句话中的表面中可以推出出作义工可以长寿。

E wrong是因为虽然有压力产生，但压力大并不能说明人就不能活得长寿（虽然好像一般是压力大寿命短，但文中并没有明确告诉我们是这样的。）而且不符合这句话的意思“that statistic would be what we would expect even if volunteering does not boost longevity”。这句话是说，即使作义工不能促进长寿但是从数据统计上可以得到我们所想要的东东（我们所想要的东东就是前面所说的作义工可以长寿的结论）

没看明白对A的解释。

A选项说样本不具代表性。
E是无关选项。题目根本没说stress这件事情
