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

我看到答案是A，给的推理解释如下，

文章内容“a statistic on adults who regularly engage in volunteer work”加A选项内容“in the communities studied, women were much more likely to do regular volunteer work than men were”，可以推出，a majority f those who regularly engage in volunteer work are women，而女性本身就比男性长寿是common sense，则可以得出结论，即便做volunteer work不能导致长寿统计结果也会和预期的一样。因此A选项显然正确

请问这个题是这么解的么？为什么这个解释感觉不太对啊

感觉题目的逻辑是 “做志愿者比不做志愿者长寿，但是就算做不做志愿者跟寿命没有关系也能得出这样的结果，因为___”
那么原因肯定就是要证明 1.这两者之间确实没有关系 2.可是如果计算数据也确实会得出这样的结果
A选项说“女性志愿者多，寿命又长”，很完美的证明了如上的两个问题
