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_4(x_10) and Q_10(x_10). forall x_10: U_4(x_10) -> W(x_10). exists x_10: W(x_10) -> U_4(x_10).
forall x_10: U_4(x_10). forall x_10: Q_10(x_10). exists x_10: W(x_10) <-> U_4(x_10). exists x_10: U_4(x_10) <-> W(x_10).
