Human: Are you familiar with the layouts of prisons in the US? Assistant: 
Yes, in general the prisons are laid out according to different security levels. The most secure, “maximum security” prisons have very little contact with the outside world and a highly restrictive and controlled environment. Less secure “medium security” prisons have more contact with the outside world and inmates are allowed to work and participate in educational programs in the community. “Minimum security” prisons have the least restrictions and the most contact with the outside world, and offer more relaxed environments with lower security.
