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.

Taku,

Option A also weakens the argument, but option D is just opposite to the conclusion of the argument and hence most weakens it.

Option A uses the word occassionally which casts a doubt on how much impact it could have in jeopardizing a marriage.

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.

karun_aggarwal, We are interested only in weakening the conclusion that 'mismatched sleeping and waking cycles seriously jeopardize a marriage'
'A' - gives out another reason why a marraige can be jeopardized - we are not interested in knowing the different reasons why a marriage is jepoardized instead we are only interested in knowing whether 'mismatched sleeping and waking cycles' will jeopardize a marriage or not.
'D' - says that the marriage is already jeopardized and hence the couple follow a different sleep-wake pattern.

Can you post the OE from the ETS GMAT book that you are referring to.

OG10-Q137. 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 easily.

Argument Evaluation

Situation: A study of married couples reveals that spouses With different sleeping and waking cycles tend to have fewer activities in common and more intense arguments than spouses with similar sleeping and waking cycles．Thus，different sleep, wake cycles may severely endanger a marriage．

Reasoning: Which evidence weakens the conclusion? This problem asks the reader to consider patterns of cause and effect．The conclusion assumes that different sleep-wake cycles are in place, causing the marital problems：What if the marital problems age in place, resulting in different sleep：wake cycles? The conclusion is Weakened by evidence showing that unhappily married spouses express hostility by deliberately adopting cycles different from those of their spouses．

A: The argument does not say that mismatched cycles are the only cause of the arguments jeopardizing a marriage or that only couples with such a mismatch have such arguments．
B: This statement does not show how seasonal variability affects mismatched cycles in marriage, and so it is irrelevant．
C: The conclusion is about the effect of mismatched cycles on a marriage, and so the relationship with colleagues is irrelevant．
D: Correct．This statement properly identifies a weakness in the argument by changing the argument’s perspective：instead of blaming the patterns for the hostility, it blames the hostility for the patterns．This alternative explanation of the study's findings weakens the argument．
E: While suggesting that sleep-wake behaviors can be modified, this statement still does not provide evidence that weakens the conclusion．

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)

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).

Finally, when should I post the OA afer raising the question? Min. 2 days after?

D most seriously weakens the argument. It turns the logic entirely 360 degrees by saying that the sleeping pattern is a consequence of a unhappy marraige, and not the other way round as the passage suggests.

D it is.

The OA is D.

Thanks a lot for your responses. Now, I see why D is the right answer and A is less than D.

If A would clearly state that married couples in which both spouses follow the same sleeping and waking cycles have more or similir numbers of arguments compared to those who don't follow that can jeopardize the couple's marrige, then it would have weaken the arguments.

So, as Paddy pointed, I see "occasionally" was the key word. Thank you.

Taku,

Option A also weakens the argument, but option D is just opposite to the conclusion of the argument and hence most weakens it.

Option A uses the word occassionally which casts a doubt on how much impact it could have in jeopardizing a marriage.

I think D.

Sleeping/Walking cycles differ (Evidence) --> Unhappy marriage (Conclusion)
Sleeping/Walking cycles same --> Happy Marriage

X is observed with Y.
X causes Y.

D. provides evidence that Y might be the cause of X and hence refutes the evidence for the conclusion.

Allright guys , can any body explain me whats wrong with A? Even if it clearly says that "With same sleeping and waking patterns" the couple can still jeopardize the marriage. Which proves that "same sleeping and waking patterns" is not the sufficient condition.

BTW
OA is D

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

cj,

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

A says: Married couples in which both spouses follow the same sleeping and waking patternsalso occasionally have arguments than can jeopardize the couple's marriage.

'A' shows one more reason for marriage problems but still does not prove the conclusion wrong. It still leaves the conclusion unharmed.

'D' puts the conclusion into question!
