Consider the question. Premise: "Four men are standing in front of a wall that is full of graffiti as another man is poised above looking down on them."
Hypothesis: "Four men are sitting on a bench."
Do we know that the hypothesis entailed by the premise?
 What is the step-by-step reasoning process to arrive at the answer: no?
The four men cannot be both standing in front of a wall while simultaneously sitting on a bench.
