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: ~q. p. q or ~q_11.
~q_11 can be inferred via the disjunctive syllogism rule. ~q and p can be inferred via the conjunction rule. p and ~q can be inferred via the conjunction rule. q_11 -> q can be inferred via the rewriting rule.
