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. 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.

I get A.

A states that gender skewed the result of the studies and therefore, we cannot conclude that increased release of endorphins increases longevity.
Had the study compared men who do volunteer work with men who don't or women who do volunteer work and women who don't then we would be making a different assessment.

Agreed its A
because it states that the "statistics would be the same" if even if volunteering does not boost longevity

The only reason could be that women live longer than men and women do volunteer work more often.
