Anthropologist: Violence is an extreme form of aggression, and is distinct from the self-expression sufficient for survival under normal conditions. Human beings in certain situations react to unpleasant stimuli with violence -- but only because they are conditioned by their culture to react in this manner. Each of the following can be logically inferred from the anthropologist's statements EXCEPT: ["Violent behavior is a product of one's cultural environment.", 'The self-expression required for survival is generally nonagressive.', 'Some behaviors are influenced by the cultures in which human beings live.', 'Not all aggression is violent.']
