premise: A person wearing a red shirt is falling off a white surfboard.
hypothesis: A surfer is being flung in to the waves after hiting a large crest.
explanation_1: Surfers have plenty of reasons to fall off of a surfboard, other than being flung by the crest of a wave.
explanation_2: Just because a person wearing a red shirt is falling off a white surfboard, doesn't mean he is a surfer.
explanation_3: A person falling off a surfboard does not imply that he is being flung into the waves, or has hit a large crest.
