刚在大牛贴出来的帖子上看到的，弱弱的问，这题选神马啊
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.、

是选c么？意思就是说他们不是真正的长寿，只是被假象所掩盖了？

A is the right answer. The argument builds its case of connection between helping others and increasing life span. A says both properties are related to another host - woman.

This is a typical correlation and causation question.

When two things - A and B - happen together, it could be
1) A causes B
2) B causes A
3) c causes both A and B

似乎有点懂了，ls的意思就是说，其实这个只是个巧合，意思就是说是因为women的原因导致了volunteer和longevity同时发生，即你说的情况三，对么？
但是如果这么想呢，women做volunteer所以longevity，men不怎么做volunteer所以不longevity，那这样岂不是不能削弱了？反而变成对题目的加强了？
然后我又有一个想法，如果真的是加强，就不能分women或者是men，换而言之，如果说的是对people进行整体研究，这样就是彻底的加强了。我这个想法是想解释你的说法。不知道我的意思你没有看懂呢？我的语文不大好。。。请见谅啊
