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 Thomas were excited, then it is raining. Thomas is excited or it is not raining. Thomas is not excited.
It is not raining can be inferred via the disjunctive syllogism rule. If it rains, then Thomas is excited can be inferred via the rewriting rule.
