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 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.

The conclusion is that "mismatched sleeping and waking cycles can seriously jeopardize a marriage."

How does the author arrive at this conclusion?

  • There was a study of marital relationships in which one partner's sleeping and waking cycles differ from those of the other partner.
  • This study revealed that such couples (those with mismatched sleeping/waking cycles) 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.

The author reasons that a mismatched sleeping/walking cycle can lead to fewer shared activities and more violent arguments, which in turn can jeopardize a marriage. We are looking for the answer choice that most seriously WEAKENS this argument:

Quote:
(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.

The author does not claim that mismatched sleep cycles are the ONLY cause of arguments that can jeopardize a marriage. Partners with the same sleeping/waking patterns might also have serious arguments, but does having mismatched sleep cycles lead to an increase in violent arguments? Choice (A) doesn't suggest otherwise, so it does not weaken the argument. Eliminate (A).

Quote:
(B) The sleeping and waking cycles of individuals tend to vary from season to season.

The sleep cycles of BOTH partners could follow the same seasonal patterns. So regardless of whether (B) is true, couples may or may not follow the same sleeping and waking patterns.

Do mismatched sleeping/waking cycles jeopardize marriages? Seasonal variability doesn't strengthen or weaken the argument, so eliminate (B).

Quote:
(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.

The argument is concerned with marital relationships in which one partner's sleeping and waking cycles differ from those of the other partner. We don't care about the effect of mismatched sleep cycles on the professional relationships of individuals in those marriages. We only care about how their MARRIAGES are affected. Eliminate (C).

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

The study shows that couples with mismatched sleeping/waking cycles 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. But does that necessarily mean that mismatched sleep cycles CAUSE a decrease in shared activities or an increase in violent arguments?

What if the hostility CAUSES the mismatched sleeping/walking cycles? Choice (D) suggests that the mismatched sleep cycles are a product of the unhappiness and hostility, not the cause of the problems. In that case, instead of mismatched sleep cycles leading to marriage problems, marriage problems lead to mismatched sleep cycles.

This reversed cause and effect relationship weakens the idea that mismatched sleeping cycles can seriously jeopardize a marriage. (D) doesn't disprove the author's argument, but it certainly works against it. Keep (D).

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

Choice (E) is tempting. This suggests that couples with mismatched sleep cycles might be able to do something to remedy their problems. But will such couples 1) realize the source of their problems, 2) be willing to do something about it, and 3) be able to undo the damage that has already been done?

We have to consider the data cited in the passage, which links mismatched sleep cycles to more violent arguments and fewer shared activities. Even if it is possible to remedy the mismatched sleep cycles, the data implies greater marriage trouble for couples with mismatched sleep cycles.

Even though there is an easy way to modify sleeping/waking cycles, we still have a correlation between mismatched sleep cycles and marriage problems. Thus, it still seems reasonable to suggest that mismatched sleeping and waking cycles can seriously jeopardize a marriage.

Choice (E) doesn't seriously weaken the argument, and (D) is the best answer.

I would choose option D.

Lets break it into two pieces:-
1)When people are unhappy about their marriages,
2)they tend to adopt a different sleeping and waking cycle from that of their spouses.

1 is responsoble for 2 which is contrary to the conclusion in the para. :-)

I also think it’s D.

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. (The argument concerns the impact of sw cycles, so this statement is irrelevant)

(B) The sleeping and waking cycles of individuals tend to vary from season to season. (Seasonality is not important for the argument)

(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. (the argument concerns marriage, not work relationship)

(D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses. (Yes! Here it is. Argument says that mismatched sleeping and waking cycles are one of the causes that could jeopardize a marriage. This statement, however, tells that this is not a cause, but an effect; i.e. unhappy marriage -> adopting of different sw cycles)

(E) According to a recent study, most people's sleeping and waking cycles can be controlled and modified easily. (says nothing about the effect of sw cycles on 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).

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.
--The argument is about those couples that have different sleeping cycles. This option is out of scope

(B) The sleeping and waking cycles of individuals tend to vary from season to season.
--Out of scope

(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.
--Argument with colleagues is out of scope

(D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses.
--Correct. This reverses the causality i.e. sleeping cycles don't cause unhappiness but in-fact it is the opposite

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