premise: A US Air-force member is handing off a little girl and her toy unicorn to a local citizen.
hypothesis: A marine is dancing with kids and their toys.
explanation_1: A US Air-force handing off a little girl and her toy is not the one dancing with the kids and their toys.
explanation_2: One cannot be both a marine and a US Air-force member. Dancing and handing off a little girl are different actions.  A little girl is one kid, not kids. "Toy" is singular, "toys" is plural.
explanation_3: It is either a marine or a member of the air force.
