While the Hmong people have since settled in Vietnam and Laos in large numbers, I omitted those two nations from this quiz as their migration to these countries has only taken place during the last three centuries. If this criteria was replicated for each of these people groups, widely multiethnic nations such as the United States could be valid answers for the majority of these people groups. I believe that this would skew the intention of this quiz (namely, that it is asking the quiztaker to identify the ancient origins of these people groups).
