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 is an office clerk or x_10 will listen to a song. For all x_10, x_10 is not an office clerk or x_10 will drive a car. For all x_10, x_10 is not curious. For all x_10, x_10 will listen to a song if and only if x_10 is curious.
For all x_10, x_10 will listen to a song or x_10 will drive a car can be inferred via the universal resolution rule. For all x_10, if x_10 listens to a song, then x_10 is curious can be inferred via the universal biconditional elimination rule. For all x_10, if x_10 were curious, then x_10 is listening to a song can be inferred via the universal biconditional elimination rule. For all x_10, x_10 will not listen to a song can be inferred via the universal biconditional elimination rule.
