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_3 -> w_1. q -> q_3. w_1 -> q.
q_3 -> q can be inferred via the transitivity rule. q -> w_1 can be inferred via the transitivity rule. w_1 -> q_3 can be inferred via the transitivity rule.
