premise: An old woman in a green and blue plaid shirt is standing on a crowded sidewalk smiling.
hypothesis: A woman watching a street performer play guitar.
explanation_1: We don't know she is smiling because she's watching a street performer play guitar
explanation_2: A woman is standing on a crowded sidewalk smiling doesn't imply a woman is watching a street performer play guitar.
explanation_3: The woman may not be watching a street performer play guitar while on the crowded sidewalk.
