What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_16: P_3(x_16). forall x_16: W(x_16) -> T_2(x_16). forall x_16: T_2(x_16) -> W(x_16). forall x_16: T_2(x_16).
forall x_16: W(x_16). exists x_16: P_3(x_16) and T_2(x_16). exists x_16: T_2(x_16) and P_3(x_16). forall x_16: W(x_16) <-> T_2(x_16). forall x_16: T_2(x_16) <-> W(x_16).
