Trevor watches a violent television show and then pretends to shoot his brother with a toy gun. A psychologist would say that Trevor has learned this behavior through Classical conditioning

Operant conditioning

Latent learning

Observational learning

observational learning

Explanation:

Trevor observed someone being a shot in a television show, then learned that behavior from seeing it. It'd be the same as learning how to play a game by watching someone else do it, or learning about marine life through a nature documentary.

answer; i believe that the correct answer is culture based resources;

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.
