Bass Explanation: - From the text, we know that there are four instruments in the school band: drums, bass, flute, and trumpet. - John plays the drums and Mary plays the flute, which are both wind instruments. - Pete plays the trumpet, which is also a wind instrument. - Lucy doesn't play a wind instrument. - The only option left for Lucy to play is the bass since all the wind instruments are already assigned to John, Mary, and Pete. Therefore, Lucy plays the bass instrument.
