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: If Jessica sleeps, then Michael is reading a book. It is raining or Michael is not reading a book. If Barbara goes running, then Jessica is sleeping.
If Barbara goes running, then Michael is reading a book can be inferred via the transitivity rule. If Michael reads a book, then it is raining can be inferred via the rewriting rule.
