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: p_3 -> ~w. s_1 -> q_11. ~q_11. w.
~s_1 can be inferred via the modus tollens rule. ~p_3 can be inferred via the modus tollens rule. ~q_11 and w can be inferred via the conjunction rule. w and ~q_11 can be inferred via the conjunction rule.
