Based on the given text, Lucy does not play a wind instrument. Since the wind instruments mentioned are the flute and the trumpet, and assuming there are only four instruments in the band, Lucy must play one of the other two instruments: drums or bass. Given the information provided, it is not explicitly stated which one Lucy plays. However, if we must choose one based on the options given (drums, bass, flute, trumpet) and assuming a simple, binary question regarding Lucy's instrument cannot be precisely answered due to lack of detail, the most accurate response considering the options given (excluding wind instruments) could be: **Drums or Bass**
