A violin constructed to have improved sound would sound different from the best-sounding existing violins.
To professional violinists, a violin that sounds different from the best-sounding existing violins sounds less like a violin and therefore worse than the best-sounding existing violins.
Professional violinists are the only accepted judges of the sound quality of violins.
Would be the best supported by those statements?
My guess is D (assuming the question is what is the best conclusion?)
(A) Only amateur violinists should be asked to judge the sound quality of newly constructed violins.
Who should be asked to judge is out of scope.
(B) Professional violinists supervise the construction of violins.
Supervision of construction is out of scope.
(C) The best-sounding existing violins have been in existence fro several centuries.
How long these violins have been in existence is out of scope.
(D) It is currently impossible to construct a violin that the only accepted judges will evaluate as having improved sound.
This is what the passage implies.
(E) It is possible to construct a violin that sounds better than the best-sounding existing violins to everyone but professional violinists.
We do not know what non professionals think.
