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 for which x will drive a car if and only if x will go running. For all x, if x plays a game, then x is running. For all x, if x drives a car, then x is a soldier. For all x, if x were a soldier, then x is playing a game.
