Consider the question. Premise: "Three children in a ball pit."
Hypothesis: "The brothers shriek with joy as they jump up and down among the balls."
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?
Not all children are brothers. The fact that three children in a ball pit doesn't imply that they shriek with joy as they jump up and down among the balls.
