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 Susan takes a plane, then Patricia is cooking. If Patricia cooks, then it is windy. It is snowing or it is not windy.
If Susan takes a plane, then it is windy can be inferred via the transitivity rule. If it is windy, then it is snowing can be inferred via the rewriting rule.
