D because it contradicts the passage's assertion that sleep cycles cause an unhappy marriage, whereas D gives an alternative explanation for the sleep cycles

We have been asked to weaken X=>Y. The easiest way to do it is show that Y=>X

Ill go against the grain and pick (E). If sleeping schedules can be easily changed, then spouses would be able to modify their circadian rythum and thereby improve relations. This would NOT jeapordize their relationship, therefore weakening the argument.

Another vote for (E)

I don't see any reason why (D) is right - it actually supports the argument

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 that 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 adifferent 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.

D for me as well.

E in fact offers another way of saying that the cycles are not brought upon by nature but are something that can be controlled/modified ..in other words folks (if they so desire) can use it to their advantage ..which goes against the ASSUMPTION that sleeping and waking cycles end up ruining marriages because they are inherent characteristics of human beings.

I will go with E.

Statement E will solve sleeping cycle differences between married partners and smoothen their relationship. This way it's weaken the argument.

Here only A and D are in scope.
However A somehow tries (although not complete) contradicts information given in the passage.

Moreover,
Conclusion can be weakened by a reasoning that is of equal strength in other direction. D serves the purpose.

No D doesn't strengthen it...

Conclusion is ----

Thus, mismatched sleeping and waking cycles can seriously jeopardize a marriage.

however D says that a jeopardized marriage leads to mismatch in sleeping and waking cycles. So it provides another explaination for the conclusion....

I thought D in fact reverses the cause and effect and hence doesn't weaken or for that matter has no role to play?

Best answer for me seemed to be A..but OA is OA ..can't help much..

If U2lover can post the OE, it would be good to see the reason.

BTW, on a lighter note, do any of you see a banner related to "sleep deprivation.com" or something of that sort at the bottom of the topic? Was wondering if these days these banners are coming up based on the topic of discussion?

The conlusion says, "mismatched sleeping and waking cycles can seriously jeopardize a marriage" i.e. A causes B

But "D" says "A doesn't cause B" in fact "B causes A", hence the answer.

I think this is from OG10, the OE is the best in OG10!

Thanks Vivek. You are absolutely right, its problem #137 in the OG10. Your explanation parallels that of the OE and it all makes sense now. E attempts to prove the conclusion wrong, whereas D actually indicates an entirely different cause.

Thanx for sticking around and helping us out!! You are both a great mentor and moderator
