The argument states in a premise that a good-quality piano is expensive, whether we buy it second-hand or not. We don't want to question that premise, even if it might not be true in real life. It's true that we don't know that a poor-quality piano makes unpleasing sounds (maybe it's just ugly to look at, or maybe it doesn't last long), but A at least gives us a reason to reconsider buying a poor piano, even for a beginning student.
Your examples about art and motorcycles are tricky, since we need to distinguish among characteristics such as quality, speed, value, and whether something is "real art." The original argument doesn't require so much complexity. If we know that all good pianos are expensive, then the second-hand part becomes irrelevant. We just need to know whether there is any reason to buy a good piano for a new student. Answer A doesn't prove that we should--maybe it's not a worthwhile investment, or maybe (as we already speculated), a poor piano does not make any bad sounds, but then again, Str/Wkn answers almost never prove the conclusion true or false. They just push in one direction or the other, like evidence in a court case.
Dear
DmitryFarber,
That's very kind of you, thank you very much for your response.
I fully agree with every word you wrote. My rationale here was that sometimes correct ACs, even though you can see that they push in the required direction, are not sound enough. To state more explicitly, since GMAT is more of a LOGIC exam sometimes what you are given is not logical
enough...
Though, the "push in one direction is enough" mentality sometimes gets lost between the lines. I think I am bit excessively critical thinker, and still working on blunting this.
Regards...
