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: Sarah is listening to a song or it is not windy. Jessica is not working. If Sarah listens to a song, then Jessica is working.
Sarah is not listening to a song can be inferred via the modus tollens rule. If it is windy, then Sarah is listening to a song can be inferred via the rewriting rule.
