Leo: Premise: "Young girl playing the violin in a long-sleeve white shirt."
Hypothesis: "The child wears long sleeves and plays an instrument."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
Since the violin is an instrument then if a young girl is playing the violin in a long-sleeve white shirt then the child wears long sleeves and plays an instrument.
Thus, the answer is yes.
