<span>A sociologist who is studying how populations of certain countries influences and affects the population and environment of other neighboring countries is likely a functionalist, who focuses on social/cultural development, international social change and or culture sociology. The focus area described allows for may courses of sub-study. The dynamic of entire populations especially those separated by boarders and boundaries can have vastly different cultural norms, the result of which when mixed can have a catastrophic difference on the perceived efficiency of that population as a whole. One example of this explanation is cultural social conflict, evident in most if not all large cities with discontinuous ethnic groups.</span>

I briefly learned about the Aztec and Inca's and from what I know, Cortes and Pizarro were both Spanish conquistadors. Cortes conquered the Aztec empire brutally, killing many common people as well as soldiers, much of Aztecs wealth was taken away and the Aztec people lived under Spanish rule for approximately 300 years.
I suggest reading back into your lesson and taking notes; it helps a lot!
