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: Linda is a soldier or John is not driving a car. If it is sunny, then Robert is a janitor. If Linda were a soldier, then it is sunny. If Robert were a janitor, then it is cloudy.
If it is sunny, then it is cloudy can be inferred via the transitivity rule. If Linda were a soldier, then Robert is a janitor can be inferred via the transitivity rule. If John drives a car, then Linda is a soldier can be inferred via the rewriting rule.
