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

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.\

对于答案A实在想不通。HOWEVER不是显示与前文不同吗

41.: GWD-23-Q39

In Gandania, where the government has a monopoly on tobacco sales, the incidence of smoking-related health problems has risen steadily for the last twenty years. The health secretary recently proposed a series of laws aimed at curtailing tobacco use in Gandania. Profits from tobacco sales, however, account for ten percent of Gandania’s annual revenues. Therefore, Gandania cannot afford to institute the proposed laws.

Which of the following, if true, most seriously weakens the argument? a

A.      All health care in Gandania is government-funded.

B.       Implementing the proposed laws is not likely to cause a significant increase in the amount of tobacco Gandania exports.

C.      The percentage of revenue Gandania receives from tobacco sales has remained steady in recent years.

D.      Profits from tobacco sales far surpass any other single source of revenue for the Gandanian government.

E.       No government official in Gandania has ever previously proposed laws aimed at curtailing tobacco use.

这题为什么不选B呢

31题前面说做志愿工作有利于长寿，however,即使志愿工作对长寿没有作用统计数据也会是这样的。也就是文削弱前半部分的。

A说参加志愿活动的女人多而女人本来就长寿，给出他因。

41题选A，因为禁烟以后的政府的医疗费用可以节省下来。B我觉得significant increase 不准确，也许slightly increase就可以compansate loss.也许出口本来就是赔钱的，increase反而对政府不好。总之没有A直接提政府fund与原文紧密
