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_8 -> u. w_3 -> q_8. u -> w_3. u -> w_3.
q_8 -> w_3 can be inferred via the transitivity rule. q_8 -> w_3 can be inferred via the transitivity rule. w_3 -> u can be inferred via the transitivity rule. u -> q_8 can be inferred via the transitivity rule. u -> q_8 can be inferred via the transitivity rule.
