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？
