Q31

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          .

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 through-

out 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.

The answer is C, but I think A is right. Kindly please help me to check this question!

要找出當義工不會長壽的原因

然而，即便當義工不會真的長壽，这个调查也会给到我们想要的这个结果（即當義工會長壽），因为

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.

說了當義工會長壽

因为當義工多是女人，而女人本来就比男人长寿 

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.　

說了endorphins掩飾了病況．只是讓症狀減輕而已.

支持當義工真的會長壽，违反原文最后一句话

D.    it is rare for a person to keep up a regular schedule of volunteer work through-

out 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.
