What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_8: U_1(x_8) -> ~W(x_8). forall x_8: T(x_8) <-> U_1(x_8). forall x_8: P_8(x_8) -> W(x_8). forall x_8: P_8(x_8) or Q_8(x_8). forall x_8: Q_8(x_8) -> W(x_8).
forall x_8: W(x_8). forall x_8: T(x_8) -> U_1(x_8). forall x_8: U_1(x_8) -> T(x_8).
