What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? exists x_10: P_10(x_10) or Q_1(x_10). forall x_10: ~P_10(x_10) or U(x_10). forall x_10: Q_7(x_10) <-> U(x_10). forall x_10: Q_1(x_10) <-> Q_7(x_10).
exists x_10: Q_1(x_10) or U(x_10). forall x_10: Q_7(x_10) -> U(x_10). forall x_10: Q_1(x_10) -> Q_7(x_10). forall x_10: U(x_10) -> Q_7(x_10). forall x_10: Q_7(x_10) -> Q_1(x_10).
