What can be inferred from the following premises in a single inference step (ignoring inferences that add new predicates or constants)? forall x_22: W_3(x_22) <-> Q_12(x_22). forall x_22: P_22(x_22) or Q_22(x_22). forall x_22: Q_14(x_22) -> W_3(x_22). forall x_22: Q_22(x_22) -> Q_14(x_22). exists x_22: ~P_22(x_22).
forall x_22: Q_22(x_22) -> W_3(x_22). exists x_22: Q_22(x_22). forall x_22: W_3(x_22) -> Q_12(x_22). forall x_22: Q_12(x_22) -> W_3(x_22).
