What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_17: Q_17(x_17) -> T(x_17). forall x_17: T(x_17) -> Q_17(x_17). exists x_17: Q_17(x_17) -> ~Q_14(x_17). forall x_17: P_14(x_17) or Q_14(x_17). forall x_17: ~P_14(x_17).
forall x_17: Q_14(x_17). forall x_17: Q_17(x_17) <-> T(x_17). forall x_17: T(x_17) <-> Q_17(x_17).
