What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall z_2: Q_3(z_2) -> T(z_2). exists z_2: Q(z_2) -> Q_3(z_2). forall z_2: T(z_2) -> Q(z_2). forall z_2: Q(z_2).
exists z_2: Q_3(z_2). forall z_2: Q_3(z_2) -> Q(z_2). exists z_2: Q(z_2) -> T(z_2). exists z_2: T(z_2) -> Q_3(z_2).
