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.

Here's my explanation: The correct answer will logically complete the sentence, and so it logically has to have something to do with what has been mentioned in the first part of the sentence, which is about volunteer not boosting longevity. The sentence also contains the keyword "however", indicating that the answer must address the fact that the author is about to say something contradictory to what has come before. So, the answer must downplay the significance of the study. I found it by POE and ignoring irrelevant answer choices.

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. (correct - this gives an alternate explanation to the study, weakening it by showing that the average age is only higher for volunteers because most volunteers arewomen and because women live longer than men)
B. The number of young adults who do regular volunteer work is on the increase (outside scope - young adults were not mentioned)
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. (irrelevant)
D. It is rare for a person to keep up a regular schedule of volunteer work throughout
his or her life. (irrelevant)
E. Some people find that keeping a commitment to do regular volunteer work
becomes a source of stress in their lives. (irrelevant)

POE really helps with this one - eliminate what is outside scope or irrelevant.

I thought that B was the correct answer, the reason was that if the number of young adults who do regular volunteer work increases, then it would be true that, "And a statistic on adults who regularly engage in volunteer work helping others shows that they live longer."

Well, first off it isn't B because young adults were not mentioned at all, and in fact the question prompt says that the study is on adults, not young adults.

It is A because you're looking for something that will logically complete the sentence, and the sentence starts off with "However, that statistic would be what we expect even if volunteering does not boost longevity, because..." This means that whatever completes the sentence MUST provide evidence supporting the fact that the results of the study (that volunteers live longer) could have possibly been caused by something other than the act of volunteering itself. Therefore the answer must be A because A is the only answer that provides us with an additional reason that people from the survey live longer. Instead of living longer simply because they are volunteering and producing endorphins, the people in the survey are living longer because they are predominantly women (since the survey only looks at people who volunteer and the survey was done in an area where women volunteer more than men), and women live longer than men.

Does that make sense?

Thank you for your explanation. I have a question on the following: "Instead of living longer simply because they are volunteering and producing endorphins, the people in the survey are living longer because they are predominantly women".

The answWomen do more volunteer work. So how do we know women live longer is due to the fact that they are women or the fact that they do more volunteer work?er said Women are more likely to do volunteer work and women live longer. Now there are two variables: 1. They are women and 2.
