What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_8, if x_8 drives a car, then x_8 is an astronaut. For all x_8, if x_8 plays a game, then x_8 is not an astronaut. There is at least one x_8 for which x_8 will play a game. For all x_8, x_8 will drive a car.
Since the premises are contradictory, we can infer anything from them.
