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: William is a bartender or Charles is a nurse. If Charles goes running, then it is windy. If Charles were a nurse, then Charles is running. It is windy or William is not a bartender.
If Charles were a nurse, then it is windy can be inferred via the transitivity rule. If William were a bartender, then it is windy can be inferred via the rewriting rule.
