Consider the question. Premise: "A child is looking through the glass at the child squirting a water hose onto the glass."
Hypothesis: "A child makes fun of the other."
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 child looking at someone else through a glass does not mean that child makes fun of that person.
