What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_11: Q_11(x_11). forall x_11: R(x_11) <-> Q_1(x_11). w -> R(b). forall x_11: Q_1(x_11) -> ~Q_11(x_11).
forall x_11: ~Q_1(x_11). forall x_11: R(x_11) -> Q_1(x_11). forall x_11: Q_1(x_11) -> R(x_11).
