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_1 -> q_2. ~w. p_11 -> w. ~q_2.
~t_1 can be inferred via the modus tollens rule. ~p_11 can be inferred via the modus tollens rule. ~w and ~q_2 can be inferred via the conjunction rule. ~q_2 and ~w can be inferred via the conjunction rule.
