Archaeologists in Michigan have excavated a Native American camp near Dumaw Creek. Radiocarbon dating of animal bones found at the site indicates that the camp dates from some time between 1605 and 1755. However, the camp probably dates to no later than 1630, since no European trade goods were found at the site, and European traders were active in the region from the 1620's onward.
Which of the following, if true, most strengthens the argument?
(A) Due to trade among Native Americans, some European trade goods would have reached the area before the European traders themselves did.
(B) At all camps in the region that have been reliably dated to the late 1620's, remains of European trade goods have been found.
(C) The first European trade goods to reach the area would have been considered especially valuable and preserved as much as possible from loss or destruction.
(D) The first European traders in the area followed soon after the first European explorers.
(E) The site is that of a temporary camp that would have been used seasonally for a few years and then abandoned.
问题分析：原文反复在谈的无非就是camp对在的时间和欧洲的trader是否在这个时间比较活跃这个信息，我们来看选项。
A说在trader来之前一些欧洲的货物就已经到达了，没说，干掉。
B说在camp里（注意这个对camp的修饰，如果所说camp和原文的camp没关系，这个选项就是无关答案了，但这个选项的时间和原文有关系），有一些欧洲的货物，这个选项整体谈的就是camp和欧洲那帮trader之间的关系，与原文所谈关系类似，留着。
C说第一批欧洲货被认为是很珍贵的并且尽可能避免被破坏，没说过，干掉。
D说第一批trader是紧随着第一批探索者之后就来的，没说过，干掉。
E说原文所说的那个地方用了几年后就被放弃了，原文没说过类似内容，干掉
