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: Michael is climbing a mountain or Barbara is not a politician. If it is windy, then Barbara is a politician. If James cooks, then it is windy.
If James cooks, then Barbara is a politician can be inferred via the transitivity rule. If Barbara were a politician, then Michael is climbing a mountain can be inferred via the rewriting rule.
