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: It is not windy. James is a police officer or William is not a cashier. If James were a police officer, then it is windy.
James is not a police officer can be inferred via the modus tollens rule. If William were a cashier, then James is a police officer can be inferred via the rewriting rule.
