This was easy. The argument basically assumes that comprises are necessary for functioning properly. Only A and D come close.

(A) Achieving political compromises is not all that is necessary for the proper functioning of a government. -- Correct. Something else other than political compromises could be the reason for proper functioning.

(D) A political party's policies could turn out to be detrimental to the functioning of a government. -- "could". Okay, it could sure. When contrasted with A though, it points out that political comprises are not a necessary condition for proper functioning of govt or in other ways there could be something else. Hence, eliminate D.

Voters commonly condemn politicians for being insincere, but politicians often must disguise their true feelings when they make public statements. If they expressed their honest views—about, say, their party's policies—then achieving politically necessary compromises would be much more difficult. Clearly, the very insincerity that people decry shows that our government is functioning well.

P : politicians become insincere when making public statements.
P : expressing honest views make compromising more difficult.
C : insincerity -> smoother compromising -> government functioning well.

Which of the following, if true, most seriously undermines this reasoning?

Any statement that weakens the linkage written in the conclusion will undermine the reasoning of the argument.

(A) Achieving political compromises is not all that is necessary for the proper functioning of a government.
-> Correct, This option implies that other factors are needed for well-functioning government and compromise cannot guarantee a well-functioning government by own. If the insincerity of politicians is only beneficial in making compromise and is harmful in other factors, which are crucial in well-functioning government, the argument's reasoning is weaken.

(B) Some political compromises are not in the best long-term interest of the government.
-> This option implies that making a compromise is not always the best choice only in limited circumstance by saying 'some'. In other words, most of the political compromise can still be long-term interest of the goverment.

(C) Voters often judge politicians by criteria other than the sincerity with which they express their views.
-> How voters judge is not the interest in this argument. What only matters is 'can the insincerity mean well functioning government?'

(D) A political party's policies could turn out to be detrimental to the functioning of a government.
-> Irrelevant. Just talking about political party's policies does not give any information about sincerity. Moreover, even some party's policies can be detrimental for the government, still it's compromise with other parties can be beneficial to the government.

(E) Some of the public statements made by politicians about their party's policies could in fact be sincere.
-> Definitely some of the statements can be sincere. However, the argument is claiming that such sincerity signifies a government that is not functioning well. Generally, the willingness to become insincere is crucial for well-functioning government according to the argument.

Which of the following, if true, most seriously undermines this reasoning?

A. Achieving political compromises is not all that is necessary for the proper functioning of a government.
B. Some political compromises are not in the best long-term interest of the government.
C. Voters often judge politicians by criteria other than the sincerity with which they express their views.
D. A political party's policies could turn out to be detrimental to the functioning of a government.
E. Some of the public statements made by politicians about their party's policies could in fact be sincere.

After going through all the posts on this thread, I can see that while many of us have gotten the answer right, hardly anyone of us has gotten it right for the right reasons.



The crux of the argument is this: Since achieving politically necessary compromises would be much more difficult with honest views than with insincerity, the insincerity of the politicians shows that our govt is functioning well.

The reason given on this thread for accepting option A is that the option shows that achieving political compromises does not help in the proper functioning of a government. Or it delinks political compromises from the functioning of the government.

Neither of these reasons is correct.

If I tell you that achieving 760 on GMAT is not all that is necessary for getting admission in Harvard (which, as you know is true since there are many other requirements), does it mean that 760 on GMAT doesn't help in getting admission in Harvard? Or does it mean that 760 on GMAT is not linked to admission to Harvard?

The answer to both the questions is No. Right?

Just that one thing is not the "only" necessary requirement doesn't mean that it is not even one of the requirements. Right?

Similarly, option A doesn't mean achieving political compromises is not good for the functioning of a government.

Rather, if I change the conclusion to "the very insincerity that people decry is good for the functioning of the government", option A will become incorrect, for the abovementioned reasons.

The reason option A is correct is that the conclusion says that the insincerity "shows" that the government is functioning well.

It's like saying "your 760 on GMAT shows that you have gotten into Harvard".

Now, if someone tells me that 760 on GMAT is not the only requirement for Harvard, my above statement will be weakened.

Right?

Similarly, since option A says that achieving political compromises is not the only requirement for the proper functioning of the government, it means that even if we achieve political compromises, other requirements may not be met, and thus, the government may still not be functioning well. Therefore, just by knowing that we have probably achieved political compromises, we cannot say that the government is functioning well.

Does it make sense?

Option B is wrong because it says "some" political compromises are not in the best long-term interest of the government. One major reason for rejecting option B is that "some" means "at least one". So, essentially option B says that at least one political compromise is not in the.... Do we really need all political compromises to be in the "best long-term interests" of the government?

No. Right?

Secondly, it talks about "political compromises" in general, not specifically "necessary political compromises", as talked about in the argument. It could be that some political compromises are not good, but probably none of them is necessary. Probably, all necessary compromises are actually good for the government. Right?

Therefore, option B doesn't weaken the argument.

Option D says "A political party's policies could turn out to be detrimental to the functioning of a government". This option uses "could", which means, as in option B, that some policies could be detrimental to the functioning of a government. Now, even if some of the policies are detrimental to the functioning of the government, does it mean that politicians should express honestly?

No. Because the reasoning of the argument stands as is. If they express honestly, achieving politically "necessary" compromises would be much more difficult.

Therefore, even if option D is true, the reasoning of the argument stands as is.

Thus, option D doesn't weaken the argument and is incorrect.

Hi ChiranjeevSingh

Could you please elaborate about the below point which you have written in your solution?
"the very insincerity that people decry is good for the functioning of the government", option A will become incorrect, for the abovementioned reasons.

The option A looks strengthener to me :

(A) Achieving political compromises is not all that is necessary for the proper functioning of a government.

It accentuates that political compromise is one of the factors, if not all alone a self sufficient factor, for proper functioning of the government. If the government is san political compromises, then obviously it must not be functioning well.

Any insightful thought of this interpretation (or misinterpretation as it OG question)?

Focus on the keywords or intent of the conclusion:

Conclusion: A is the only way B works.
What will weaken it? If you say that B can work in another way C too.
We are not saying that A is not the way. We are saying that A is not the only way.

Conclusion: A is sufficient to show B.
What will weaken it? B needs other things too.
We are saying that A is not sufficient. It may be necessary but it is not sufficient.

Conclusion here: Insincerity shows that our government is functioning well.
You can weaken it by saying that just insincerity does not show that our Govt is functioning well. You need other things too.

Seems the question is giving trouble to many so here are my views on it.

Voters commonly condemn politicians for being insincere,
Politicians often must disguise their true feelings when they make public statements.
If they expressed their honest views—about, say, their party's policies—then achieving politically necessary compromises would be much more difficult.

Conclusion: Clearly, the very insincerity that people decry shows that our government is functioning well.

The argument links 'insincerity' to 'politically necessary compromises' to 'government is functioning well'. We need to undermine this reasoning.

(A) Achieving political compromises is not all that is necessary for the proper functioning of a government.

Correct. This says that "political compromises" does not lead to "proper functioning". There are other things required too. So we cannot conclude that the govt is functioning well only because it achieves political compromises.

(B) Some political compromises are not in the best long-term interest of the government.

"Long term interest of the govt" is not relevant to our argument.

(C) Voters often judge politicians by criteria other than the sincerity with which they express their views.

How voters judge politicians is irrelevant.

(D) A political party's policies could turn out to be detrimental to the functioning of a government.

Note that what the political party's policies are and how they impact the functioning of the govt is irrelevant to us. We are saying that "political compromises" lead to a well functioning govt. The argument mentions "political policies" only as an example - if politicians expressed their honest views about say political policies, political compromise may not be achieved. Actually the argument links "honesty of politicians" to "political compromise" to "functioning of a government" and that is what we need to worry about.

(E) Some of the public statements made by politicians about their party's policies could in fact be sincere.

This just says that politicians are not "always dishonest".

Answer (A)

KarishmaB
To clarify, the argument is basically saying that achieving political compromises IS ALL that is necessary for the proper functioning of a government?

In my view, the argument does not seem too full on to imply this because it uses phrases such as "often must" and "functioning well". "Often must" does not equal always. "Functioning well" does not necessarily equal properly functioning. No? Is Choice A an example of a case where this answer weakens the argument to an extent?

Thank you!

I am not sure but isn't D a strengthener here because we are saying that policies could be detrimental to the functioning of govt (probably because they cannot get compromise); so they must not be honest about it all the more because if they are detrimental and they are being honest about it, then definitely they will not get the necessary compromise.

Also I am bad with politics and I do not understand how this is working- which compromise is being referred to? Who will compromise with whom? How will any compromise be beneficial to anyone? How will being honest/ dishonest about it lead to any compromise? Why does member of A political party have to express honest opinions about them? MartyTargetTestPrep GMATNinja KarishmaB ThatDudeKnows avigutman

If you can explain by taking a case of 2 parties A and B and taking n example of such compromise/ policies, that may help

Conclusion: insincerity shows gov't functioning well
Premise: honesty would make compromising difficult
So, insincerity-->compromise-->gov't functioning well

Answer choice A does a good job of breaking that last arrow, so I hope you're comfortable that A is the right answer.

Okay, now for your questions.

First, a disclaimer: I can't caution you enough about spending too much time in the rabbit hole that is "what if the question asked __." Trying to figure out whether an answer choice on a weaken question would qualify as a credited response if we were instead asked to strengthen is a variation of that. People love to do this analysis, and I think it usually just distracts from the REAL take-aways from a question. My suggestion is never to do it.

That said, here's a little discussion on D. :| If you need to go through as many steps in a logical progression as you did in your explanation (and especially if your explanation includes the word "probably"), I can all but assure you that you've got the wrong answer choice. GMAC asks us to follow logical progressions, but keep in mind that with each step along the path (unless the steps are rock solid), the path gets a little shakier. Too many steps ends up with a very shaky path, and that's not what GMAC is after.

I don't agree with your path on D. If a policy is detrimental but I'm able to get it enacted by compromising with you, such that you support my detrimental policy in exchange for me supporting whatever it is that you want, then my detrimental policy won't result in the government functioning well, and government functioning well was our conclusion. But just because some policies could be detrimental, that doesn't show that government isn't functioning well. Maybe the detrimental policies won't get enacted for some other reason aside from the honesty/insincerity bit. As above, though, I'd get out of this rabbit hole and move on to a different question!

As for politics, generally, perhaps the second sentence of the preceding paragraph helps clarify how GMAC was using the concept of compromise in politics?

Hi KarishmaB : Two quick questions - i understand what you say in Red above. I believe the original question is similar to what you have in red

I DONT understand what you have in blue however.

Q1) Could you give a simple example of what you claim in the blue.

^^ KarishmaB -

Q2)

A is sufficient for B
vs
A is necessary for B

How are you so sure - that perhaps the original question is not the format of the 2nd type (i.e. A is NECESSARY for B)

If the format was to be instead - A is necessary for B , what would be the conclusion instead ?

Below are my attempts of what might the conclusion look like if the format is to be instead - A is necessary for B

Thoughts ?


Quote:
Attempt # 1
,,,,
Conclusion - political compromise is needed for good functioning of government.


Quote:
Attempt # 2
,,,,
Conclusion - political compromise is a must for good governance


Quote:
Attempt # 3
,,,,
Conclusion - if good governance is to occur, political compromises have to be made

Quote:
Attempt # 4
,,,,
Conclusion - without political compromise, good governance cannot be achieved.

Hi avigutman - what if (A) was saying this instead

Quote:

(A-original) Achieving political compromises is not all that is necessary for the proper functioning of a government.

(A-variant) Achieving political compromises is not all that is necessary for the proper functioning of a government.

I believe (A-variant) too would weaken the argument.

If Achieving political compromises is NOT NECESSARY for the proper functioning of a government - i think that would weaken the conclusion

Agreed. jabhatta2. The argument assumes that the proper functioning of a government requires only political compromises.
(A-original) weakens that assumption directly.
(A-variant) weakens that assumption as well (arguably even more so than (A-original) does.)

Voters commonly condemn politicians for being insincere, but politicians often must disguise their true feelings when they make public statements. If they expressed their honest views—about, say, their party's policies—then achieving politically necessary compromises would be much more difficult. Clearly, the very insincerity that people decry shows that our government is functioning well.

Which of the following, if true, most seriously undermines this reasoning?

(A) Achieving political compromises is not all that is necessary for the proper functioning of a government.

(B) Some political compromises are not in the best long-term interest of the government.

(C) Voters often judge politicians by criteria other than the sincerity with which they express their views.

(D) A political party's policies could turn out to be detrimental to the functioning of a government.

(E) Some of the public statements made by politicians about their party's policies could in fact be sincere.

Insincere Politicians

Step 1: Identify the Question

The word undermines indicates that this is a Weaken the Argument question.

Step 2: Deconstruct the Argument

V: P insincere

P must hide feelings

Else diff to compromise

Ó Insincere à gov functioning well

Step 3: Pause and State the Goal

On Weaken questions, the correct answer makes the conclusion less likely to be valid. Often on Weaken questions, you will want to attack gaps in the logic of the argument. Do you see any gaps between the premises and conclusion?

Step 4: Work from Wrong to Right

(A) CORRECT. The premise says that disguising true feelings is needed for compromises, while the conclusion says that insincerity shows that the government is functioning well. These are not the same thing. If things other than compromises are also necessary in order for a government to function well, then the ability to achieve compromises, by itself, does not mean that the government is functioning well overall.

(B) The argument states that political compromises are necessary. For this to be the case, not all political compromises need be in the government’s best long-term interest. Moreover, the relationship between a government functioning well and long-term interests is not clear; these two ideas are not necessarily the same thing.

(C) The argument states that insincerity is a criterion voters consider. The fact that voters consider other factors as well does not influence the conclusion drawn about insincerity.

(D) The conclusion relates to whether compromises promote the functioning of the government. Whether some policies may not help in this functioning does not directly relate to the conclusion.

(E) The fact that some statements may be sincere does not diminish the premise that politicians may still be insincere in certain instances.

Argument Evaluation

Situation
Politicians must often make insincere public statements because expressing their true feelings would make it harder for them to achieve politically necessary compromises.

Reasoning
What would suggest that the argument's premises do not establish that politicians' insincerity shows our government is functioning well? The implicit reasoning is that insincerity helps politicians achieve politically necessary compromises, and these compromises help our government to function well, so insincerity must show that our government is functioning well. Evidence that these necessary compromises do not ensure that our government functions well would undermine the argument's reasoning, as would evidence that politicians' insincerity has other substantial effects that hinder the government's functioning.

(A) Correct. If governments may function poorly even when insincerity allows necessary political compromises to be made, then the argument's premises do not establish that politicians' insincerity shows our government is functioning well.

(B) The argument does not require that all political compromises help government to function well, only that politically necessary compromises do.

(C) Even if voters often judge politicians by criteria other than their sincerity, they may also often decry politicians' insincerity, not realizing or caring that such insincerity helps the government function well.

(D) Even if a political party's policies impair the government's functioning, politically necessary compromises by politicians in that party could improve the government's functioning.

(E) Even if politicians sometimes speak sincerely about their party's policies, their general willingness to be insincere as needed to achieve politically necessary compromises could be a sign that the government is functioning well.

Factor 1:
Voters Opinion: People decry politician's insincerity
Factor 2:
Reason for politician's insincerity: To achieve politically necessary compromises

Conclusion:
Factor 1 shows that Factor 2 is valid
"the very insincerity that people decry "
"shows that our government is functioning well."

Logic:
Insincerity (Factor 1) => Politically Necessary Compromises(Factor 2) => Government is functioning well (Conclusion)

Conclusion in own words:
government is functioning well because politicians disguise their true feelings for achieving politically necessary compromises .

Which of the following, if true, most seriously undermines this reasoning?

(A) Achieving political compromises is not all that is necessary for the proper functioning of a government.
This weakens as this is not the only reason for proper functioning of a government.
