What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall y: S_3(y) -> Q_3(y). forall y: T(y) -> S_3(y). forall y: Q(y). exists y: T(y).
exists y: S_3(y). forall y: T(y) -> Q_3(y). exists y: T(y) and Q(y). exists y: Q(y) and T(y).
