GMAT Critical Reasoning Discussions

Answer is C.Reason-:-To undermine the advertisement's claim, we have to look for an option that provides the reason for the increased sale other than the effectiveness of the drug. Option C fits here.

My take is on C too. We have to undermine the reason why hospitals are prescribing Novarex as pain killer.

My Take E.Since sleeping cycles can be easily modified , it can not jeopradise marriage.In D , it is expressed that the people in unhappy marriage express hostility by following different sleeping/waking cycles.This statement weakens the argument because the effect is confused with the cause.Although D is also logically correct,but i see the E to be best choice


The biggest point we all miss out is that in a "strengthen/weaken" question, we need to see what argument will strengthen/weaken the relationship between the evidence and the conclusion (I learnt this off Kaplan, and it sure does help me :)).

Now, if you see (E)

"According to a recent study, most peoples sleeping and waking cycles can be controlled and modified easily."

Agreed that most people's sleeping and waking cyclces can be controlled and modified easily. How does it link to the conclusion? The conclusion states

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

So, how does (E) affect the conclusion? Any person would deliberately modify his/her cycle to jeopardize a marriage? and if it is so, why don't we choose a direct answer (D) that states it explicitly. Why go with (E)?

What we need to presume here is all the statements (including the argument and conclusion) to be true. We should only point out a counter-argument which will weaken the author's stand at that point in time. Not necessarily prove them wrong completely. We don't see the author coming up with a rebuttal and hence we assume that we need to prove his/her point wrong.

I'd go with (D) anyday. Since, you are aware of OG11, please go through the CR question (I can't recollect the number as of now) that has to do with the study of drug addicts and the manipulative behavior. You'll know why the answer is (D) and not (E). I'll try and post the question here today sometime later.



@magic...

My take is on E. D is not correct since its talking about unhappy marriages not about reasons which lead to marraige failure.


Hello shashank,After your reply, i researched into other sources to find out the correct answer and reasoning for the question above and i found the following reasoning.Assumption in the question-: mismatched sleeping/waking cycle is a cause of marital issues. Statement D: marital issues leads to mismatched sleeping/waking cycle. Thus D Weakens the argument.This question is the typical example of the trick used my GMAT to confuse between the cause and effect.Choice E is incorrect.This question is from OG10. and OA is D. Thanks for bringing my attention to this question. Hope i added value to the discussion.
@magic...

And how does (E) talk about marriage failure? I fail to see that in (E).

Plus, jeopardize does not mean marriage failure, it just means rough patches which could lead to failure but not necessarily a failure in itself.

Ye, I saw that. It's a mistake that would help you learn better stuff, so it's not a mistake after all :). And thanks to you, I get to think about other options as well, otherwise I choose one and move on :).

one from me..

An international study recently examined the effects of second-hand smoke on health.Surprisingly, although the dosagees of harmful chemicals from second-hand smoke are so small that their effect should be negligible, the study found that nonsmoking spouses of smokers displayed an incidence of heart disease that was significantly greater than that of nonsmokers who were not as regularly exposed to second-hand smoke.

Each of the following , if true , could contribute to an explanation of the unexpectedly high incidence of heart disease in smokers' spouses EXCEPT.

(A) A disproportionately high number of people married to smokers are among the older segment of the married population , a group that inherently has a higher than avrage risk of the heart disease.
(B) On Average, more alcohol and coffee, both of which have been linked to heart disease, are cosumed in the homes of smokers than in the homes of nonsmokers
(C) A disproportionately high number of smoker are married to other smokers, and the risk of heart disease increases in proportion to the number of smokers living in a househod.
(D)Smokers generally tend to livevin higher-stress enviroments than do non-smokers, and stress is a factor associated with above average incidence of heart disease.
(E) A disproportionately high number of smokers live in areas with a high level of industrial pollutants , which have been shown to be a factor in inceaed risk of heart disease.


Let us discuss and try to find the correct answer to this question.

We have to find an ODD MAN OUT Statement.Best approach in these type of questions is to go by choices.
(A) A disproportionately high number of people married to smokers are among the older segment of the married population , a group that inherently has a higher than avrage risk of the heart disease.
This statement supports the explanation. Thus not the answer.
(B) On Average, more alcohol and coffee, both of which have been linked to heart disease, are cosumed in the homes of smokers than in the homes of nonsmokers
This statement also supports the explanation. Thus not the answer.
(C) A disproportionately high number of smoker are married to other smokers, and the risk of heart disease increases in proportion to the number of smokers living in a househod.
This satement is fishy. We are looking for the reason for increased number of heart diseases in second hand smokers. if smoker is married to smoker there is no second hand smoker in house. But the second part of statement states that the heart disease increases in proportion to the number of smokers living in a househod i.e. Risk of heart disease for nonsmoker living with smoker is more than for the nonsmoker living with nonsmoker. Thus this statement also supports the explanation
(D)Smokers generally tend to livev in higher-stress enviroments than do non-smokers, and stress is a factor associated with above average incidence of heart disease.
If smoker is living in higher stress environmnt, it does not means that the nonsmoker spouse is also living in high stress environment . According to me this statement doesn't support the explanation.
(E) A disproportionately high number of smokers live in areas with a high level of industrial pollutants , which have been shown to be a factor in inceaed risk of heart disease.
This statement also supports the explanation. Thus is not the answer. Please pour in your take along with explanations

There are fundamentally two possible changes in an economy that will each cause inflation unless other compensating changes also occur. There changes are either reductions in the supply of goods and services or increases in demand. In a prebanking economy the quantity of money available, and hence the level of demand,is equivalent to the quantity of gold available. If the statements above are true , the it is also true that in a prebanking economy A. Any inflation is the result of reductions in the supply of goods and services B. If other factors in the economy are unchanged, increasing the quantity of gold available will lead to inflation. C. If there is a reduction in the quantity of gold available ,then , other things being equal, inflation must result D. the quantity of goods and services purchasable by a given amount of gold is constant E. whatever changes in demand occur , there will be compensating changes in the supply of goods and services.

My response is B because increase in gold quantity will lead to more money and thus more demand. If demand is increased then as per the passage inflation is bound to increase

Is it "d" ? From the question it looks we need to find a fact that is true in this economy.

I'd go with (B). Here they speak of consumption of alcohol and coffee, but not necessarily by the non smoking spouses. So, it doesn't quite add up for me.

My take is B

Inflation results from :- Goods and services reduced supply OR Increase in demand

pre banking day settlement: any transfer of financial instruments, and / or cash, prior
to the opening of the relevant central bank on any given
day. It is also often referred to as overnight settlement.

A. It cannot be inferred because it may be due to high demand
B. This is my answer. Because increasing the quantity of gold will lead to increasing demand and since other factors like supply or compensating factors reain constant, it will lead to high inflation.
C. Reducation of gold will result in reduction of demand, so its against the premise.
D. If this is true then inflation will never occur.
E. If compensating factor occurs along with demand then there is no inflation.

OA
'B'.

I expected 'C' answer. In 'B' if quantity of gold increases it will result in decrease demand not increase. When a supply is lowered its demand increases and vice a versa. demand and supply are inversly proportional . Is there any other justification for 'B' to be correct???

Finally my text alignment problem is solved.. :drinking:

Guess you're confusing gold to be the goods. But as stated, it is actually the level of demand (in other words, money). So, if the level of demand increases and there are no goods and services to meet the demand, inflation increases. Hope this clarifies your doubt.

none of the answer seems correct.
