OG一道CR，纠结纠结纠结中。。。

Outsider1988

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?

答案是(D)
People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses

非常的不理解，我觉得这个有点strengthen了啊

OG给的解释说The argument assumes that mismatched sleeping and waking cycles precede martial problems。不明白啊

原题是建立在一个前提之下，就是夫妻二人希望能够在同一same sleeping 和waking cycle之下，如果夫妻二人故意不处于same sleeping 和waking cycle，则就谈不上这个cycle对他们marriage的影响了这个题属于结论错误

原题说的是：经调查不在一起睡的人感情更容易变差。
前提是本来样本夫妻感情都是正常的，是因为分睡感情才变差的。

而选项说：感情差了才导致了不在一起睡。
这样就直接否定了题目的论述了：

不是因为不一起睡才感情不好，是感情不好才不一起睡。
