premise: A girl in a green knit cap stands ready to push a sled, with a little boy behind her.
hypothesis: A sad girl in a green knit cap stands ready to push a sled, with a little boy behind her.
explanation_1: You can not infer the girl is sad.
explanation_2: It is not sure whether she is happy or sad
explanation_3: Sentence one does not indicate the girl's emotional state. Being sad is just one of many emotions she could be feeling. She could be happy because she is playing, angry because she has to push a sled or bored because she is not sledding.
