What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? There is at least one x_10 for which x_10 will play a game or x_10 will not drive a car. For all x_10, if x_10 plays a game, then x_10 is driving a car. For all x_10, if x_10 plays a game, then x_10 is taking a plane.
There is at least one x_10 for which if x_10 drives a car, then x_10 is playing a game.
