What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_10: R_1(x_10) -> R(x_10). forall x_10: Q_4(x_10) <-> R_1(x_10). forall x_10: W(x_10) -> Q_4(x_10). exists x_10: Q_4(x_10) -> W(x_10). forall x_10: ~R(x_10).
forall x_10: ~R_1(x_10). exists x_10: Q_4(x_10) <-> W(x_10). exists x_10: W(x_10) <-> Q_4(x_10). forall x_10: Q_4(x_10) -> R_1(x_10). forall x_10: R_1(x_10) -> Q_4(x_10).
