Does region having the 4 choices of domain mean that this has a collection of 4 answers , so you have to make a entity for it. Or does is it an attribute because it only holds 1 choice? Lol i dont know if that makes sense . But i keep goin back and forth on those 2 choices. But im leaning towards making it its own entity because they give you a collection of choices
