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: Mary is driving a car or Karen is listening to a song. Mary is not driving a car or James is sad. For all x, x will not listen to a song.
Karen is listening to a song or James is sad can be inferred via the resolution rule. If Karen makes tea, then Mary is driving a car can be inferred via the rewriting rule.
