Leo: Premise: "A man wearing a red name-brand shirt with stripes on it and red sun glass and a red hat has some kind of music player in his hand that he is listening to with blue earphones."
Hypothesis: "Someone is listening to a smartphone."
Do we know that the hypothesis entailed by the premise?
Mei: OK, So, let's think first...
Me:
A man with a music player and earphones does not imply that it is a smartphone.
Thus, the answer is it is not possible to tell.
