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: p_3 -> r_11. r or ~u_3. r_11 -> s. r -> p_3.
p_3 -> s can be inferred via the transitivity rule. r -> r_11 can be inferred via the transitivity rule. u_3 -> r can be inferred via the rewriting rule.
