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.
(B) The sleeping and waking cycles of individuals tend to vary from season to season.
(C) The individuals who have sleeping and waking cycles that differ significantly from those
of their spouses tend to argue little with colleagues 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 easil

答案：D，同意，A中我认为错在occasionally,是部分否定，如果把这个词去掉，是不是削弱？谢谢。

我认为这里削弱的应该是mismatched sleeping and waking cycles
can seriously jeopardize a marriage.

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.
这里occasionally不是否定的意思而是说偶然.所以去除和不去除我觉得关系不大.A并没有针对结论削弱.
