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: t -> w_3. q -> t_1. r or q. q_11 -> t. t_1 -> q_11. r -> w_3.
q -> q_11 can be inferred via the transitivity rule. q_11 -> w_3 can be inferred via the transitivity rule. t_1 -> t can be inferred via the transitivity rule.
