What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_6: Q_2(x_6) -> R_2(x_6). forall x_6: ~Q_6(x_6). forall x_6: R_3(x_6) -> Q_6(x_6). forall x_6: R_3(x_6) -> Q_2(x_6). forall x_6: R_2(x_6) -> R_3(x_6).
forall x_6: ~R_3(x_6). forall x_6: Q_2(x_6) -> R_3(x_6). forall x_6: R_3(x_6) -> R_2(x_6). forall x_6: R_2(x_6) -> Q_6(x_6). forall x_6: R_2(x_6) -> Q_2(x_6).
