What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_17: P_3(x_17). forall x_17: T_3(x_17) <-> Q_17(x_17). forall x_17: P_3(x_17) -> W(x_17). forall x_17: W(x_17) -> Q_17(x_17).
exists x_17: W(x_17). forall x_17: P_3(x_17) -> Q_17(x_17). forall x_17: T_3(x_17) -> Q_17(x_17). forall x_17: Q_17(x_17) -> T_3(x_17).
