What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists z_2: U_2(z_2) -> ~P_3(z_2). forall z_2: T(z_2). forall z_2: P_3(z_2).
exists z_2: ~U_2(z_2). forall z_2: T(z_2) and P_3(z_2). forall z_2: P_3(z_2) and T(z_2).
