Model response

AI
bass The instruments are drums, bass, flute, and trumpet. John plays drums, Mary plays flute, Pete plays trumpet. The remaining instrument is bass. Lucy doesn't play a wind instrument; flute and trumpet are wind instruments, so she can't play those. Drums are played by John, leaving bass as the only option.
