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: q_13 -> r_13. r_13 -> w. p_3 or ~w. p_3 -> q_13.
q_13 -> w can be inferred via the transitivity rule. p_3 -> r_13 can be inferred via the transitivity rule. w -> p_3 can be inferred via the rewriting rule.
