What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_10: U(x_10) -> R(x_10). forall x_10: R(x_10) or W(x_10). forall x_10: W(x_10) -> U(x_10). forall x_10: R(x_10) -> U(x_10).
forall x_10: W(x_10) -> R(x_10). forall x_10: U(x_10). forall x_10: U(x_10) <-> R(x_10). forall x_10: R(x_10) <-> U(x_10).
