premise: Small red airplane flies over mountaintop dropping red substance over fire.
hypothesis: the plane is a firefighter.
explanation_1: Not all planes are firefighter planes.
explanation_2: Dropping a red substance over the fire does not make the plane a firefighter.
explanation_3: If a small airplane flies flies over the mountaintop dropping red substance over fire, it does not mean that the substance dropped is meant to fight the fire and hence it also does not mean that the plane is a firefighter.
