Can someone explain why A is incorrect?

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.

This is one of the all time favorite things for the gmat.
This is a case of cause/reaction that can we reversed. What if the unhappy couples decided to sleep at different times, so that mismatched sleeping cycles are a RESULT of an unhappy marriage (not the cause)? The argument says "mismatched sleeping ==> jeopardized marriage", but what of "mismatched sleeping <== jeopardized 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.
The argument does not states that "Married couples in which both spouses follow the same sleeping and waking patterns" do not have arguments, it states that have FEWER arguments, so option A does not weaken the argument because the argument does not rely on this extreme position:
"Married couples in which both spouses follow the same sleeping and waking patterns have no argument (...)"
(D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses.
D is the correct answer because exposes the other possibility (that things happen the other way round).

(D) Cause & Effect has been reversed - that is one of the weakening techniques according to CR Bible
Argument: mismatched sleeping cycle --> jeopardize a marriage
(D) unhappy marriage --> partner adopt a different sleeping cycle to express hostility

Choice D

Type weaken
Conclusion: mismatched sleeping => unhappy marriage
Assumption: mismatched sleeping lead to unhappy marriage.

in choice B, season could lead to changes in sleep-wake cycles, but it happen for both partners. Hence, dispite B state a new possible cause, nut this cause does not effect the argument

Hi
I just have one question. According to oa:D ... Unhappy people tend to change to different sleeping cycles..OK fine but this could still mean that the marriage is affected.. Hence still support the conclusion correct?

On the other hand if the oa were E/B the conclusion is clearly refuted. E: says different cycles is easy to mend therefore marriage can be saved
B: seasonal effect means it has no effect on marriage ..both these refute the conclusion drawn by author..

What I mean is whether a->b or b->a... Presence of a indicates b and b indicates a, which is exactly what the author concludes.. That a->b
To refute this wing it be better if we altogether break the relationship between a and b and show them as unrelated events?

Can someone pls clarify this.. Thanks

D
Conclusion - mismatched sleeping and waking cycles can seriously jeopardize a marriage.
Premise - mismatch b/w cycles leads to more arguments
Weaken - More arguments may lead to mismatch b/w cycles

Option D: "People in unhappy marriages have been found to express hostility by adopting a different sleeping and

The way I read option D, it states that individual became hostile after adopting to different cycle. So this supports assumption ans hence strengthener. Does it anyway states that hostility induced difference in sleeping pattern. In that case it would be a weakener.
