137. A study of marital relationships in which one partner's sleeping and waking cycles differ from those of the other partner reveals that such couples share fewer activities with each other and have more violent arguments than do couples in a relationship in which both partners follow the same sleeping and waking patterns. Thus, mismatched sleeping and waking cycles can seriously jeopardize a marriage.
Which of the following, if true, most seriously weakens the argument above?
(A) Married couples in which both spouses follow the same sleeping and waking patterns also occasionally have arguments than can jeopardize the couple's marriage.
(D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle fro m that of their spouses.
对于D.没有问题. 我想问A. 不考虑occasionally程度问题, 为什么A不可以理解为 非A--->B的削弱.
难道他因不可weaken因果型结论吗?
"Lawyer实战篇: 因果型结论weaken的4种方法: A。是其他原因或可能导致该结果。B。割断因果:或有因无果或有果无因。C。因果颠倒了。D显示因果关系的资料不准确。 "
这题到底是因果型削弱还是充分必要型削弱?
另: lawyer大牛以前的讲解:
因果型结论的weaken:
结论是: 24小时上CD导致我考800分
i) 其他原因或可能导致该结果: 因为我刻苦学习 所以我考上 800;
ii) 割断因果(有果无因): 我没有24小时上CD 也考上800分;
iii) 割断因果(有因无果): 我24小时上CD 我也没考上800分;
iv) 因果倒置: 因为我考上800分 所以我24小时上CD.
这题A的削弱就是i)的方法. 为什么在这题中不对呢?
我觉得关于因果型,充分必要型,很重要. 想了好几天了,都没个结果. 望大N指点迷津!!!!
