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_2 -> ~w. t_2. q_1 -> w_2. w.
~w_2 can be inferred via the modus tollens rule. q_1 -> ~w can be inferred via the transitivity rule. t_2 and w can be inferred via the conjunction rule. w and t_2 can be inferred via the conjunction rule.
