What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_12, if x_12 plays a game, then x_12 is driving a car. For all x_12, x_12 will play a game if and only if x_12 will work. For all x_12, x_12 will work or x_12 will not drive a car.
For all x_12, if x_12 drives a car, then x_12 is working. For all x_12, if x_12 plays a game, then x_12 is working. For all x_12, if x_12 works, then x_12 is playing a game.
