What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? Name the inference rule being used: Jennifer is an electrician. For all x_9, x_9 will not drive a car. For all x_9, if x_9 were an electrician, then x_9 is driving a car.
Since the premises are contradictory, we can infer anything from them.
