单项选择题
What occurred during the four centuries of attempted European conquest in the Americas merely extended the continuum of history into a new arena. The successes of these new arrivals and their descendants, consistent with the Line historical tendencies in human behavior, came at the expense of people whose kinship-based tribal system still operated on communitarian, if exclusive,
principles. Only the tribes of the southern hemisphere had become fully settled and had entered into their own era of empire-building. Unfortunately, the European people had achieved both technological and organizational superiority as these characteristics applied to the art of warfare whereas the tribes of the southern hemisphere had numbers in their favor but had no time for the adoption of European weaponry or strategy, a situation that contrasted sharply with that in North America where the tribes gained considerable access to modern weapons and were more flexible in their strategies. The two most important advantages the European-Americans possessed in the north was the endless stream of migration that more than replaced the population lost during warfare,and a production system centered in large and relatively secure population centers.
A、 Unfortunate on the whole, but surprising in historical terms
B、 Less disruptive in South America
C、 Too ethically complex to be easily judged
D、 Unexpected, given the history of similar conquests in Europe
E、 Tragic but inevitable, given historical circumstances
