3.  Zone Enumeration             (b)       A proposal exists that reconciles these two, or it is obvious they can be, or they are unrelated
4.  Zone Enumeration II                     (b)       No proposal exists to reconcile these two, nor is it obvious they can be
5.  Zone Enumeration III               (b)       These two cannot be reconciled
