premise: Two young children are standing in hall.
hypothesis: The children have their feet on the ground.
explanation_1: The phrase young children is indicative of particular age range where "children" could be of any age. "standing in hall." specifies being inside a building or structure of some form, where "feet on the ground" could also mean, "outside".
