请教OG-137 D选项

sunjueliang

137. A study of marital relationships in which one partner's sleeping and waking cycles differ from those of th e 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.
D. people in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses.
我做时能够用排除法选出D。可仔细研究选项时，好象觉得D虽然有关却没有起到削弱的作用啊。好象自己在读句子的时候对于句意的把握有些问题。
诸位帮忙分析一下D选项吧，谢谢咯

典型反因果削弱。结论：A -> B.削弱：B -> A.
conclusion: mismatched cycles -> bad marriage. Weaken: bad marriage -> adopt different cycles.

反因果削弱可以理解，但是希望那位XDJM能把我从牛角尖里拉出来。我总觉得E 也有weaken。

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

E说明，婚姻好坏和人们的作息习惯是没有关系的，因为作息习惯是可以控制和改变的。
