premise: A group of people prepare hot air balloons for takeoff.
hypothesis: There are hot air balloons on the ground and air.
explanation_1: You can not infer they are on the ground and air.
explanation_2: Preparing hot air balloons for takeoff doesn't necessarily mean there are already hot air balloons in the air.
explanation_3: Takeoff implies the ballons are still on the ground and not yet in the air.
