What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? For all x_3, x_3 is an artist or x_3 will drive a car. There is at least one x_3 for which if x_3 were an artist, then x_3 is fast. For all x_3, x_3 will drive a car if and only if x_3 is fast.
For all x_3, if x_3 drives a car, then x_3 is fast. For all x_3, if x_3 were fast, then x_3 is driving a car.
