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. How-
ever, that statistic would be what we would expect even if volunteering does not
boost longevity, because          .

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.

the number of young adults who do regular volunteer work is on the increase

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.

it is rare for a person to keep up a regular schedule of volunteer work through-
out his or her life

Some people find that keeping a commitment to do regular volunteer work
becomes a source of stress in their lives.

不能理解此题，能请牛牛再详细的解释一下吗？

选A.

题目的意思是说人们在帮助他人时,大脑会分泌E这种物质,这会让人感到幸福安宁.说有经常的分泌E能够使人长寿.统计数据表明那些经常自愿去帮助别人的成年人比不去帮助别人的人要活得长..然而,即使帮助别人不能促进长寿,我们依然能得到上面统计数据同样的结果.自愿去帮助别人的人比不去帮助别人的人还是要活得长.是否帮助别人与是否长寿无关.

那么A说在被调查的社区里,女人们比男人更可能去做一些志愿者的工作,而且女人比男人长寿.也就是说是因为女人本身比男人寿命长,性别差异导致的长寿,而不是因为帮助别人导致的长寿.

我觉得关键是对文章最后一句话的理解：However, that statistic would be what we would expect even if volunteering does notboost longevity, because          .统计结果也是我们所期望的，即使是义务劳动本身也不能延长寿命，因为－－。可以推断出选项必须是1、不延长寿命，2、统计结果可能被其它原因误导了。我支持选A。

汗，一开始也错选了C。

谢谢6楼的解释，支持答案选A。最后一句中“expect”如果理解为“预期”，这题也就不难了，唉！还是语言本身的问题。

How-ever, that statistic would be what we would expect even if volunteering does not boost longevity, because          .

然而，即使Volunteering不能促进长寿，这个统计也是我们能够预期的到的，因为：_______.
