Consider the question. Premise: "Two people sitting on a tree stump in front of a pond."
Hypothesis: "People sitting outside by a pond."
Do we know that the hypothesis entailed by the premise?
 What is the step-by-step reasoning process to arrive at the answer: yes?
Sitting in front of a pond is a way of sitting by a pond and a pond is outside so if people are sitting by a pond then they are sitting outside.
