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_12: ~Q_12(x_12) or R_6(x_12). forall x_12: P_12(x_12) or Q_12(x_12). forall x_12: R_6(x_12) -> Q(x_12). forall x_12: ~P_12(x_12) or R_12(x_12). forall x_12: R_12(x_12) -> Q(x_12). forall x_12: P_8(x_12) or ~Q(x_12).
forall x_12: Q_12(x_12) or R_12(x_12) can be inferred via the universal resolution rule. forall x_12: Q(x_12) -> P_8(x_12) can be inferred via the universal rewriting rule.
