Final answer:
The statement "Claire plays basketball with her friends. Claire is playing the piano." is False.
Step-by-step explanation:
The statement "Claire plays basketball with her friends. Claire is playing the piano." is False. The sentence suggests that Claire is simultaneously playing basketball and the piano, which is not possible as these activities require different sets of skills and physical presence. It is important to note that Claire can play basketball at one point in time and play the piano at a different point in time, but not simultaneously.
