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. p_11 or ~w_1. q.
~w_1 can be inferred via the disjunctive syllogism rule. ~p_11 and q can be inferred via the conjunction rule. q and ~p_11 can be inferred via the conjunction rule. w_1 -> p_11 can be inferred via the rewriting rule.
