What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_6: P_6(x_6) -> ~Q_6(x_6). forall x_6: Q_6(x_6). forall x_6: T(x_6) or W_3(x_6). forall x_6: T(x_6) <-> P_6(x_6).
forall x_6: ~P_6(x_6). forall x_6: T(x_6) -> P_6(x_6). forall x_6: P_6(x_6) -> T(x_6).
