What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_11: P_11(x_11) -> Q_11(x_11). forall x_11: P_11(x_11). forall x_17: W_1(x_17) and Q_17(x_17).
forall x_11: Q_11(x_11). forall x_17: W_1(x_17). forall x_17: Q_17(x_17).
