What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_5: Q_3(x_5) <-> T_2(x_5). forall x_5: P_4(x_5). forall x_5: T_2(x_5) -> ~U_4(x_5). forall x_5: P_4(x_5) -> U_4(x_5).
forall x_5: U_4(x_5). forall x_5: Q_3(x_5) -> T_2(x_5). forall x_5: T_2(x_5) -> Q_3(x_5).
