question: piano:playing
choices.label: A B C D
choices.text: art:sketching calligraphy:exhibition brush:paint erhu:dubbing
explanation: one can "play" the "piano". "sketching" is a way of painting, and painting is a form of "art". "sketching" and "art" correspond, but the corresponding relationship is inconsistent with the query. there is "calligraphy" in the "exhibition", but "calligraphy" is not a tool, and the corresponding relationship is inconsistent with the query. one can "paint" with a "brush". "erhu" and "dubbing" have no obvious logical relationship.
