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: w_3 -> t_1. ~w. p_1 -> w_3. t_1 -> w.
~t_1 can be inferred via the modus tollens rule. w_3 -> w can be inferred via the transitivity rule. p_1 -> t_1 can be inferred via the transitivity rule.
