Consider the question. Premise: "A man and a woman stare at the ground."
Based on this premise, can we conclude that the hypothesis "The man and women are trying to find a ring that they lost." is true?
Options:
- yes
- it is not possible to tell
- no
 If the answer is 'it is not possible to tell'; explain the reasoning:
A man and woman staring at the ground aren't necessarily trying to find a ring that they lost.
