一道GWD语法题请教大家

31. GWD26-Q31 A

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.


疑问：虽然我没觉得其他选项是对的，但也没觉得A是有道理的，题目中不是已经假设了even if volunteering does not boost longevity嘛，但A还是说boost longevity了啊，大家怎么理解？

这道题的关键在于看懂问题：
However, that statistic would be what we would expect even if volunteering does not boost longevity,because____

“就算志愿劳动无法延长寿命，这个数据也会符合我们的预期，因为？”
【这数据指的是： 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——经常参加志愿活动帮助别人的人比那些不参加志愿活动的人，活得长~】

即，题目问的是：找一个神马样的原因，使结论加强。

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
“研究表明，女性比男性做志愿活动更多，而且女性比男性活得长。”
正确。这个题考的是调查样本和调查整体。
调查整体中女性志愿活动比例高，而女性寿命长，所以样本整体的调查结果肯定也符合这个规律。
