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_11 or ~w. ~p. ~p_11. p or q_1.
~w can be inferred via the disjunctive syllogism rule. q_1 can be inferred via the disjunctive syllogism rule. ~p and ~p_11 can be inferred via the conjunction rule. ~p_11 and ~p can be inferred via the conjunction rule. w -> p_11 can be inferred via the rewriting rule.
