Why was the 9th amendment included in the bill of rights

Because it states rights that were not added in the constitution, i'm pretty sure. Good luck! ^.^

you should think about the answers you give and expect the same form your questions.

an informal structure in a bureaucracy would be something like so-called "office politics". where there's a formal structure set up for the organization, but then an informal subculture as well that has a way of organizing the bureaucracy further. this can be positive because it sets up an added degree of organization, albeit informal, within the bureaucracy.
