Philosopher: Graham argues that since a person is truly happy only when doing something, the best life is a life full of activity. But we should not be persuaded by Graham's argument. People sleep, and at least sometimes when sleeping, they truly happy, even though  they are not doing anything.
 
Which one of the following most accurately describes the role palyed in the philosopher's argument by claim that at least  sometimes when sleeping, peoopel are trully happy, even though they are not doing anything?

B It is an example inteneded to show that a premise of Graham's argument is false.

D.It is an example intended to disprove the conclusion of Graham's argument.

为什么D不对呢?"But we should not be persuaded by Graham's argument" 难道作者不是反对 G的结论吗?

Graham说“A(a person is truly happy only when doing something) --> B(the best life is a life full of activity)”。

作者那句只是反对了A。但A不成立不一定说明B不成立。作者的话并没有驳斥B的存在 ：）

the conclusion of Graham's argument is "the best life is a life full of activity"

问题问的是play what role？不是哪个选项是正确的

作者的argument一直在G的那个conditional reasoning的premise里打转，所以说问的作者的话play的是个什么role，就是在否认G的前提。同意2楼。

例证为“前提假，结论必然假”。

This question is to test if you can distinguish between Premise and Conclusion. If you are not sure which part is premise and which part is conclusion, add "therefore" to the beginning of each part. For example, "Graham argues that since a person is truly happy only when doing something, [THEREFORE,] the best life is a life full of activity", then you know the first part is Premise, and is what author is against.

好像有点儿明白这个意思了, 问的是ROLE,  所以它本身的内容更重要? 结论到底是什么不重要? 不知道理解的对不对?

------------------------------------------
这个是什么意思啊? 前提假,为什么结论就一定是假的?
比如: 一个 survey 支持一个结论 , 如果survey的方法错了, 结论就是错的吗?

“前提假，结论必然假”。
这是逻辑学的基本结论。
