Model input

User/Human

What instrument does Lucy play based on the following text? Only return the instrument, nothing else.

In the school band, there are four instruments: drums, bass, flute, trumped.
John plays the drums, Mary plays the flute, and Pete plays the trumpet. Lucy doesn't play a wind instrument.

Model response

bass
The instruments are drums, bass, flute, and trumpet. John plays drums, Mary plays flute (a wind instrument), and Pete plays trumpet (a wind instrument). Lucy doesn't play a wind instrument, so she can't play flute or trumpet. The remaining instruments are drums (played by John) and bass. Thus, Lucy plays bass. Only "bass" is returned.
