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: s -> r. p_3 -> q_4. w -> p_3. r -> w.
s -> w can be inferred via the transitivity rule. w -> q_4 can be inferred via the transitivity rule. r -> p_3 can be inferred via the transitivity rule.
