Passage Summary: Violence isn't a natural survival instinct; it is a learned behavior that people only use because their culture taught them to react to unpleasant things that way.

Reasoning: Violence is defined as an extreme form of aggression that is distinct from survival-based self-expression and occurs only due to cultural conditioning.

Analysis: This is a 'Must be True EXCEPT' question, which means four of the choices are supported by the text and one is not. The stimulus provides a very strong conditional: Violence occurs ONLY because of cultural conditioning (Violence -> Cultural Conditioning). It also explicitly separates violence from survival. You should look for an answer choice that contradicts these rules—for example, any claim that violence is innate, biological, or necessary for survival would be the 'EXCEPT' because it violates the anthropologist's strict definitions.
