What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall y_3: S(y_3) -> T(y_3). forall y_3: ~T(y_3). forall y_3: S(y_3) -> T(y_3). forall y_3: U_3(y_3) -> S(y_3). exists y_3: T(y_3) -> U_3(y_3).
forall y_3: ~S(y_3). forall y_3: ~S(y_3). forall y_3: U_3(y_3) -> T(y_3). forall y_3: U_3(y_3) -> T(y_3). exists y_3: T(y_3) -> S(y_3). exists y_3: S(y_3) -> U_3(y_3). exists y_3: S(y_3) -> U_3(y_3).
