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_3(x_8) or T_3(x_8). forall x_8: P_1(x_8) <-> T_3(x_8). forall x_8: U_3(x_8) <-> P_1(x_8).
forall x_8: P_1(x_8) -> T_3(x_8). forall x_8: U_3(x_8) -> P_1(x_8). forall x_8: T_3(x_8) -> P_1(x_8). forall x_8: P_1(x_8) -> U_3(x_8).
