OG10-Q137. A study of marital relationships in which one [#permalink] New post 18 Jun 2008, 01:22
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.

[Reveal] Spoiler: OE
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.

The correct answer is D.

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 occasionallyhave arguments than can jeopardize the couple's marriage.-> irrelevant
(B) The sleeping and waking cycles of individuals tend to vary from season to season.-> irrelevant
(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.->irrelevant
(D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses.-> this weakens as this reverses the quoted part above.
(E) According to a recent study, most people's sleeping and waking cycles can be controlled and modified-> eliminate it
easily.

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)

study of married people : partner's sleeping & waking cycles differ
reveals (it doesnt say causes) such couples share fewer activities and have more violent arguments than couples with same sleep/waking pattern.
Mismatched sleeping/waking cycles seriously jeopardizes a marriage.

The conclusion jumps too far. For conclusion to be true, we need to be sure that marriage is not jeopardized by anything else other than mismatched sleeping/waking cycles or what if the marriage was bad to start with and causes mismatched sleeping/waking cycles ?
D falls in line with the above.

IF, X & Y co-exist. It does not mean X -> (causes) Y. For this to be true, we need to be sure that Y does not cause X.

Ritula : you said you dont agree with OA. What is the OA anyway....
if OA = D, think now you have some reasons why it should be D.
if OA is not D, then probably all of us agree with you. :)

Conclusion is : Mismatched sleeping and waking cycles CAN seriously jeopardize a marriage.

Mismatched sleeping -leads to - marriage in jeopardy.

(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.
Our conclusion speaks about couples whose sleeping pattern is mismatched, we are not bothered about couples whose sleeping pattern is similar. This is a Shell Game Ans (powerscore CR)

(D) People in unhappy marriages have been found to express hostility by adopting a different sleeping and waking cycle from that of their spouses.This one truely weakens the argument by showing a reverse relationship.

Re: A study of marital relationships in [#permalink] New post 05 Jul 2011, 08:50
B, C and E are out of scope i think.
One may get confuse between A and D.
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.
i would reject this choice based on 2 factors - (1) the use of word 'occasionally' and (2) it is just a trap from the original argument merely by not stating anything about the couples who follow different patterns of sleeping / waking.

D is the best choice. It is not X causes Y. but it is because of Y people do X.

Re: OG10-Q137. A study of marital relationships in which one [#permalink] New post 23 Mar 2012, 13:40
I have chosen the answer D for this question:

This is a cause and effect relationship - mismatched sleep and waking cycles can cause problems in a marriage.

There are a few ways in which we can weaken this argument. We can try to find an alternate cause for the same effect; show that when the cause occurs the effect does not occur; show that when the effect occurs the cause never occurred; show that the reversed relationship can happen; or show that there is a problem with their study.

A. This a tricky answer choice. It definitely seems like it could be right, but upon closer look, we know that is in fact an incorrect answer. The reason is because it does not have the form of one of the weakening arguments. Essentially it is negating the cause and effect relationship and saying that this will weaken the argument. However, just by negating the cause and effect relationship, it doesn't mean that the argument is undermined.

B. We are not concerned with how sleeping and waking cycles vary with the seasonal change.

C. We are concerned only with how sleeping and waking cycles affect a marriage, not the relationship with coworkers.

D. This is the correct answer. The reason is because the reversed relationship of the cause and effect is present here. Therefore, we have a presented a statement that weakens the argument.

E. We are not concerned with modifying and controlling people's sleep and waking cycles.
