An electric piano designed to have perfect frequency for

narrowed down to D & E.....marked E....****!

Let us first look at what the stimulus is telling us.

1. Electric pianos have better frequencies than the recognized Grand Pianos
2. Professional Pianists don't accept these as better because they sound different from the recognized Grand Pianos.
3. These people are the only accepted judges of piano quality.

What is the conclusion you can draw from this?

That professional pianists wouldn't accept electric pianos to being superior over Grand pianos. Now let's look at answer choices. Comments in red/green.



Hope this helps.



No, if the stimulus doesn't explicitly or specifically state anything about the preferences of other people, then we can rule out the possibility of it being the right answer under the argument of it being "out of scope". An answer in an inference type question must be fully supported by the stimulus. Hence the correct answer would have the tone of "certainty" as opposed to "possibility". Hope this clears up your doubt.

Whiplash,
I am confused.
D says it is IMPOSSIBLE to... Well the stimulus says that "an electric piano designed to..", and that the "professional pianists are the only ones to judge".. If professional pianists are the only ones to judge and clearly they don't like the sound of the so-designed pianos, and it is clear that the world is made up of people other than the professional pianists, why cannot we infer that there are other people to whom the pianos would sound better than they do to the professional pianists? To me D is strongly worded. E leaves a possibility open. What is really in-scope and what is really out of scope.

if the stimulus says A does not like B, is it not reasonable to infer that not(As) might like B?

Professional pianists are a group of people who can judge whether a piano is better than the existing grand pianos. The stimulus says that these people don't like the sound of the electric pianos. Hence it would be IMPOSSIBLE for these judges to ever admit that an electric piano is better than the existing Grand Pianos.

It is currently impossible to create an electric piano that [highlight]accepted judges[/highlight]will evaluate as being an improvement on existing grand pianos.

We are clear on the notion that accepted judges, i.e. the professional pianists will never accept an electric piano to be better than the existing pianos. This is exactly what option D says, that it is IMPOSSIBLE to create an electric piano that the accepted judges, i.e. professional pianists, would evaluate as being better than existing pianos.

This basically breaks down to saying that professional pianists will NEVER accept any electric piano to being better than a grand piano. This is what the conclusion from the stimulus says as well.

Because we don't care about the other people. Option D talks about accepted judges, and that refers only to the professional pianists. Not anyone else.

Well then "An electric piano designed to have perfect frequency for each note would sound different than the best Baldwin or Steinbach Grand Piano currently available." reading this I assumed there are other electric pianos that can behave differently, meaning that this only refers to a class of electric pianos that are "designed to have a perfect frequency', clearly there are other electric pianos out there.. I note that the stimululs says that these professional pianists dislike the "pianos that sound different", it does not say "electric pianos".. So with this mind:

D - refers to electric pianos. What about the electric pianos that are not designed the way the stimulus mentions them.. perhaps they can be liked by professional pianists?
E- also refers to electric pianos. It is a possibility.

I would tend to agree with you had the stimulus flat out stated that the professional pianists disliked electric pianos, however it refers to "pianos that are different sounding".. Are all electric pianos different sounding? I can't make that conclusion from the stimulus...

The stimulus clearly states that electric pianos would sound different. And we can take this as a given.

The thing that struck me as odd about E was the fact that we are NOT given ANY information about how other people perceive these pianos. So we cannot assume the stimulus supports that when there is no information given to us at all.

Well I see your point.. I guess the thing is it is what GMAT thinks is right.. However, I still am not convinced that saying "A object designed to have X" means that all A's have X. If that were the case then it would just say "All As have X", the designed to is not required... And I noticed that the pianists were dealing with "different sounding" pianos, no reference to electric pianos anymore..

I think in the Verbal section the best you can do is in SC, then RC and then in CR. CRs can be debatable unlike SC... Good discussion though

Haha, that is true. There is no concrete example because it's all a matter of perspective sometime. You just gotta learn to think like the GMAT.

Whiplash really well explained.Even i felt for the trap.Really liked this CR.Once again for the wonderful healthy discussions....Gmat Club Rocks!

Is this a 700+ question??? Does anyone know?

It's tagged as a 700 Level Question. Please look for these things before posting, thank you.

D is the only ans..
E is incorrect..as we dnt know abt everyone..may b everyone agree with professional pianist...

Shouldnt we try to avoid extreme and biased answer on Gmat . " Impossible seems to me as quite an extreme word ; however E does leaves some room for a possibility ;

So to sum up - i generally avoid these extreme words like - impossible , unanimous , Never , Surely , only -

Am i wrong in my approach ? Can any of the experts reply to this please .
