Which of the following conclusions about pre-Columbian Mesoamerica is best supported by the information contained in this map?

(A) The region was governed by a centralized state. (B) Cultures there did not trade extensively. (C) Much of Mesoamerica was heavily urbanized. (D) Mesoamerican societies remained isolated from each other.Explanation: (C) This question requires use of evidence. Be careful in these cases not to pick answers that may be true according to general knowledge, but not proven or indicated by the map (or whatever stimulus material is provided). The map contains no evidence for A, and the directional arrows make B or D unlikely. The proliferation of cities in such a relatively small space makes C the best choice.
