premise: A man jumps from one boulder to another and two men try to catch him as he barely makes it. hypothesis: A man leaps across the gap between two boulders and two other men attempt to break his fall as he narrowly makes it.
entailment: Jumping is the same as leaping. Jumping from one boulder to another means there is a gap between the two boulders. Two men attempting to break one man's fall are trying to catch him. Narrowly and barely can be used in place of each other.
