What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_17: P_17(x_17) <-> T(x_17). ~p -> q. p -> T(f). forall x_17: ~P_17(x_17).
forall x_17: P_17(x_17) -> T(x_17). forall x_17: T(x_17) -> P_17(x_17). forall x_17: ~T(x_17).
