What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_17: T(x_17) -> Q_17(x_17). forall x_17: U(x_17) <-> U_2(x_17). forall x_17: U_2(x_17) <-> T(x_17). forall x_17: S_3(x_17) <-> U(x_17). forall x_17: ~Q_17(x_17).
exists x_17: ~T(x_17). forall x_17: U(x_17) -> U_2(x_17). forall x_17: U_2(x_17) -> T(x_17). forall x_17: S_3(x_17) -> U(x_17). forall x_17: U_2(x_17) -> U(x_17). forall x_17: T(x_17) -> U_2(x_17). forall x_17: U(x_17) -> S_3(x_17).
