Student: Premise: "A determined professional skier is going down the slopes in a tournament."
Hypothesis: "A skier is passing another competitor in a tournament while racing down a slope."
Do we know that the hypothesis entailed by the premise?.
Teacher: Let's think:
The skier may already have passed everyone or may be at the back and it may be impossible for him to be passing anyone. So the final answer is it is not possible to tell.
