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 错选了C，答案给的A。A说女士比男士更可能做志愿活动，女士比男士活得长。这不是支持原文了么？可以题目不是应该驳斥吗？

圈出来的部分，说是用that不用which，但是没明白为什么

曼哈顿里的例句 A hard worker and loyal team player, the new project was managed by Sue. 书上说的是前面的modifier会错误修饰project,但平时阅读的时候读到这个是能够判断这个修饰语是不会用来修饰project的，会对阅读产生阻碍但不会令人误解。因此想问Gmat语法中这种例子是绝对不对还是不优呢。

还请MAY老师帮忙解答下这道题，我选的B，没弄明白，谢谢

请问数学老师 为什么这个题不是0.8*0.4+0.2*0.6。因为两个不同时发生啊

请问数学老师 这个题为什么不能直接是九分之二

请数学老师解答。这个题您没答完吗？这是系统出问题了吗？
