我一开始也是错选C了,看了解释后明白了:
此题结论为- volunteer works -> llive longer. 然后问weaken。
题目最后一句话为解题关键:即使volunteer works不能-> longevity; 数据仍显示volunteer works -> endorphines -> longevity.
为什么呢?
因为(1)数据里sample里面女生数量>男生数量(女生相较于男生更爱去做志愿者帮助他人),
plus (2)女生寿命>男生寿命
所以不是volunteer works make people live longer而是女生志愿者作为majority比较长寿而已。

这个和常识无关,而且GMAT中根本就不能用常识做题A对是因为女人本来就比男人寿命长(women tend to live long ...
I don't agree with you.
There are two reasoning types in the GMAT CR questions.
When you deal with one type of questions, such as Must be true and Main point, you have to eliminate your real world thinking. Everything you want to get in the answer choices must come from the stimulus.
However, when you deal with another type of CR questions, such as Assumption, Weaken, and Strengthen, you have to put yourself back into the mode of real world thinking. Fore instance, he assumption has to be true in order for the conclusion in the stimulus to be true. If you follow the exact information provided in the stimulus, how could you get the right answer choice?
Remember, when you deal with GMAT CR questions, go to extreme! Either real world thinking or formal logic. Get yourself used to the changes in the two different reasoning.
引用一下RON在视频里的解释:
填空题其实本质上跟weaken的题目是一样的
将题目简化后如下:
statement:do volunteer work help people live longer
however:people can live longer without doing volunteer work
所以这个问题本质上等于弱化原有的“做志愿者可以使我们活的更久”这个逻辑链
