What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_3: R(x_3) -> ~Q_3(x_3). forall x_3: Q_3(x_3). forall x_3: Q_1(x_3) <-> R(x_3).
exists x_3: ~R(x_3). forall x_3: Q_1(x_3) -> R(x_3). forall x_3: R(x_3) -> Q_1(x_3).
