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？

请数学老师解答 谢谢老师

老师，我选的是D选项，因为我认为前后表达的语意上没有因果关系，所以没有必要用A那种形式，doubling作结果状语。D选项就是一种对前面增长多少的修饰，感觉比较合理，希望老师能够完整解答一下这道题的解题思路和步骤，谢谢老师。

在AC两个选项中间纠结了很久，因为这两个选项只有时间状语语序上的区别，最后觉得C把时间状语放在前面表意比较清楚一点，请老师纠正一下我的错误，再讲讲这道题的解题思路，谢谢！

请数学老师解答下 为什么选a 谢谢老师

我的思路是这样的:看到A选项有because 和so就给排除了，B选项句子结构太碎了，而且觉得好像larger than和farther than是并列的不能一个当做修饰一个重点说，C选项句子结构不完整，E选项缺少主句。D选项的句子前面成分可以看成是sun的修饰成分，觉得还是比其他选项优秀的，就选了D。请老师纠正一下我的错误并解答一下这道题的解题思路。谢谢！*^_^*

这道题我就没看懂句义，错选了B,认为原句想表达的句义是:就像.....一样。请老师完整解答一下这道题的解题思路，谢谢老师。

麻烦老师给我解答一下，刚才是我选择B答案纠结了一下，就是顺着读下去that are inseparable很容易理解成修饰social phenomena 主谓不一致，就是that 从句是可以跳跃修饰到emotions 上的吗？这个部分不是很清晰。

请老师给我讲解下这一题，我自己是采取带值的方法，感觉这样子不是很合理。
