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 ________________________

Which of the following most logically completes the argument?
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.

there is contradictory opinion on its answer.. let's discuss together

my pick is C.. bcuz the main point is about volunteer work, boosting longevity and wellbeing.. the Q asks about another alternative effects volunteer work can have rather than boosting longevity...i think C can fit here well

+ 1 for A

A only provides an alternate explanation as in why the stat would remain the same.

the Q asks about another alternative effects volunteer work can have rather than boosting longevity
The question rather asks about what else other than the release of endorphins could be the source of longevity in the communities studied ". However, that statistic would be what we would expect even if volunteering does not boost longevity, because ________________________ "

So you should be looking for an alternate causal of the long age of the community serving member

Which is very clearly given by A
