Student asked: Premise: "An older woman in a white shirt is trying on a hat while glancing in the mirror while another older woman in a loud print shirt looks on."
Based on this premise, can we conclude that the hypothesis "A woman tries on a hat that she wants to buy as her sister looks on." is true?
Options:
- yes
- it is not possible to tell
- no
