premise: Two girls one in a gray dress the other in a black striped dress are playing with hula hoops.
hypothesis: The girls are sisters and are playing together outside.
explanation_1: Girls can have many relationships, not all girls are sisters.  Hula hoops can be played with inside or outside, the location cannot be inferred.  Two girls playing the same thing in proximity to each other does not indicate that they are playing together.
