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: Thomas is a bartender or it is not sunny. If Thomas sleeps, then it is sunny. If it snows, then Thomas is sleeping.
If it snows, then it is sunny can be inferred via the transitivity rule. If it is sunny, then Thomas is a bartender can be inferred via the rewriting rule.
