There is no evidence that the boy glides his fingers along the keys. Instead, he may be playing deliberately or in a stacatto style. Additionally, amputees have been shown to be able to play instruments with their feet; we cannot be sure he is playing the piano with his fingers.


Context: A young boy playing the piano.
Hypothesis: A young boy glides his fingers along the piano keys

Given this context, is the hypothesis true (Yes/No/I don't know)?
