What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Sarah is driving a car or it is late. For all x_8, x_8 is a server if and only if x_8 will drive a car. For all x_8, x_8 is not a server.
For all x_8, if x_8 were a server, then x_8 is driving a car. For all x_8, if x_8 drives a car, then x_8 is a server. For all x_8, x_8 will not drive a car.
