Consider the question. Premise: "A woman wearing brown boots and holding a red cup walks through a large outdoor crowd."
Hypothesis: "A woman is drinking alcohol at a concert."
Do we know that the hypothesis entailed by the premise?
 What is the step-by-step reasoning process to arrive at the answer: it is not possible to tell?
A woman holding a cup doesn't imply drinking alcohol and walking through a crowd doesn't imply a concert.
