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: For all x_10, x_10 will not listen to a song. For all x_10, x_10 will listen to a song or x_10 will not play squash. For all x_10, if x_10 drives a car, then x_10 is playing squash. For all x_10, if x_10 were a janitor, then x_10 is driving a car.
For all x_10, if x_10 were a janitor, then x_10 is playing squash can be inferred via the universal transitivity rule. For all x_10, if x_10 plays squash, then x_10 is listening to a song can be inferred via the universal rewriting rule.
