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_8: Q(x_8) -> Q_8(x_8). exists x_8: Q_8(x_8) -> S(x_8). forall x_8: R_6(x_8) -> Q(x_8). forall x_8: Q_6(x_8) -> Q(x_8). forall x_8: ~P_6(x_8) or R_6(x_8). forall x_8: P_6(x_8) or Q_6(x_8).
forall x_8: R_6(x_8) -> Q_8(x_8) can be inferred via the universal transitivity rule. forall x_8: Q_6(x_8) -> Q_8(x_8) can be inferred via the universal transitivity rule. exists x_8: Q(x_8) -> S(x_8) can be inferred via the existential transitivity rule. forall x_8: Q_6(x_8) or R_6(x_8) can be inferred via the universal resolution rule.
