How a judge’s role in government different from a senator or the president?

The judges role is very different from the president and the senetor becuase they allow the new rules of the president, and its a branch of the congress

It's most likely choice a, it makes the most sense in my opinion.

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.
