Read the passage. The piano tuner warned that the instrument would never sound new, but Nikhil did not want new. He wanted the uneven middle C, the pedal that sighed before settling, and the thin scratch his sister had made near the music rack. As the tuner worked, Nikhil understood that repair was not the same as erasure. The piano's worth lay in making old sounds playable, not in hiding that time had passed. Which choice gives the clearest restatement of the passage's stated main idea about repairing the piano?
