What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? P_10(a_10). forall x_23: T_3(x_23) -> T(x_23). forall x_23: T(x_23) -> T_3(x_23). forall x_23: P_10(x_23) -> T_3(x_23).
exists x: P_10(x). forall x_23: P_10(x_23) -> T(x_23). forall x_23: T_3(x_23) <-> T(x_23). forall x_23: T(x_23) <-> T_3(x_23).
