What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_11: P_5(x_11) <-> T_4(x_11). forall x_11: S_1(x_11) <-> T_4(x_11). forall x_11: ~P_5(x_11).
forall x_11: S_1(x_11) -> T_4(x_11). exists x_11: P_5(x_11) -> T_4(x_11). forall x_11: T_4(x_11) -> S_1(x_11). exists x_11: T_4(x_11) -> P_5(x_11). exists x_11: ~T_4(x_11).
