Premise: "A janitor stands on a moving walkway whilst cleaning in an airport."
Hypothesis: "A janitor is cleaning the front area of the airport."
Do we know that the hypothesis entailed by the premise? Step by step answer:
The front area of an airport does not always necessarily have to have a moving walkway. And moving walkways do not have to be placed in the front area of the airport. They can be put anywhere in the airport. Or the airport can just not have them. Therefore, the final answer is it is not possible to tell.
