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 it is windy, then it is snowing. It is not windy. It is windy or it is not snowing.
It is not snowing can be inferred via the disjunctive syllogism rule. If it snows, then it is windy can be inferred via the rewriting rule.
