premise: A girl holds onto a rope above the water.
hypothesis: A girl is trying to escape from a crocodile.
explanation_1: Sentence 1 does not mention anything about present danger, especially from a crocodile.
explanation_2: the sentence doesn't state there is a crocodile near the girl let alone trying to escape.
explanation_3: Just because a girl holds onto a rope above the water does not mean she is trying to escape from a crocodile.
