A study of marital relationships in which one partner's sleeping and waking cycles differ from these 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 pattens.Thus , mismatched sleeping and waking cycles can seriously jeopardize a marriage .

which of the following , if true ,most seriouly weakens the argument above ?

(A) Married couples in which both spouses follow the same sleeping and making pattens also occasionly have arguments that can jeopardize the couple's marriage.

(B) The sleeping and waking cycles of individual tend to vary from season to season

(C) The individuals who have sleeping and waking cycles that differ significantly from these of their spouses tend to argue little with colleagus at work

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

(E) According to a recent study , most people's sleeping and waking cycles can be controlled and modified easily.

答案是D~我选了A。我觉得A取反后是支持原文的，不就是削弱了吗，为什么选D呢？

我觉得A肯定不对，但是不看答案的话我肯定更不会选D。。。
根据答案的话，我理解的是原文的论点：mismatched sleeping and waking cycles 推出more violent arguments 导致unhappy marriages    D选项是 unhappy marriages 导致故意mismatched sleeping and waking cycles

我觉得D项是反过来了，所以当时没有选~那你能说下为什么不选A么？谢谢

teddyabc

因为原文里并没有说其他的不吵，只是如果sleeping and waking cycles

differ 会have more violent arguments ，A选项不矛盾啊~

我也对A有些疑问....虽然说是occasionally...但是好歹也是反对了原文所

谓的differ cycles can jeopardize a marrige...

因为这里是same cycles jeopardize a marrige~~~

大虾们再来讨论一下呀~~~

Correlation and causation.

When two events A and B happen together, the possibilities are:
1) A causes B
2) B causes A
3) C causes both A and B
4) C causes A and D causes B.

So in this argument, it says A causes B. D says B causes A.

个人觉得 D因果倒置是削弱题的最佳选项
