premise: Two people are running in the grass by a hill.
hypothesis: A man and a woman are running as part of their training for a marathon.
explanation_1: We cannot infer the sex of the two people running.  It also fails to tells us if they are doing as part of training for a marathon.
explanation_2: Just because men are running in the grass doesn't mean they are training for a marathon.
explanation_3: If you see two people running in the grass by a hill doesnt mean they are a man and a woman who are running as part of thier training for a marathon.
