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_5, if x_5 listens to a song, then x_5 is driving a car. For all x_5, x_5 will not drive a car. For all x_5, x_5 will listen to a song if and only if x_5 will drive a car.
For all x_5, x_5 will not listen to a song can be inferred via the universal modus tollens rule. For all x_5, if x_5 listens to a song, then x_5 is driving a car can be inferred via the universal biconditional elimination rule. For all x_5, if x_5 drives a car, then x_5 is listening to a song can be inferred via the universal biconditional elimination rule. For all x_5, x_5 will not listen to a song can be inferred via the universal biconditional elimination rule.
