premise: A red bi-plane leaves a white trail in a blue sky.
hypothesis: The red plane is landing on the ground.
explanation_1: A plane can only land on the ground, not in the sky.
explanation_2: A plane landing on the ground cannot be busy leaving a white trail in the sky.
explanation_3: A bi-plane and a plane are not necessarily the same thing. If the plane is leaving a trail in the sky, it is not landing.
