The trends depicted in the map above led most directly to which of the following social developments?

(A) Social stratification based on division of labor (B) Increased discrimination against ethnic minorities (C) Heightened influence of organized religion (D) Proto-industrialization of agricultural productionExplanation: (A) This question deals with causation and also requires knowledge related to the stimulus material, but not directly addressed by it. In this case, consequences are at stake. Answer B is far removed from the subject of the map. Answers C and D could conceivably be considered long-term or indirect aftereffects of the rise of sedentary societies based on agriculture, but the social stratification caused by the division of labor would have happened more immediately and more obviously.
