Consider the question. Premise: "Several men and woman dressed in orange vests walking down a snow-covered road in winter."
Based on this premise, can we conclude that the hypothesis "The construction workers had to work in the snow." is true?
Options:
- yes
- it is not possible to tell
- no
 What is the step-by-step reasoning process to arrive at the answer: it is not possible to tell?
People are not 'construction workers' just because they wear orange vests. Walking together does not imply work being done.
