premise: Young barefoot girl begins to lose balance.
hypothesis: The girl is falling onto the concrete.
explanation_1: A girl losing her balance does not imply she is falling onto the concrete.
explanation_2: Losing balance doesn't always result in a fall. A young girl could be standing on any type of floor not always concrete.
explanation_3: Not all girls who begin to lose their balance end up falling.  Not all falls happen on concrete.
