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: forall x_5: P_5(x_5) or Q(x_5). forall x_5: ~P_5(x_5) or R_5(x_5). ~Q(a_3) or p_1.
forall x_5: Q(x_5) or R_5(x_5) can be inferred via the universal resolution rule.
