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.

这是46题呀亲
说在密歇根的人类学家在某处挖掘到了一个美洲土著人的营地。用某种方法鉴定这里动物骨头，发现这个营地大概是在1605-1755年间存在的。然而，这个营地不太可能是在1630年后还存在（存在于1630年之前），因为没有在这里找到欧洲贸易商品的遗迹，但是来自欧洲的商人从1620年代开始就已经活跃在这个区域了。

B选项说，那些被精确定位确实在1620年代之后的土著人营地，都有发现欧洲贸易商品的遗迹。
直接证明文中（有没有欧洲贸易商品遗迹）的标准的正确性，如果在1620‘s后则有遗迹，最给力强化了提出“因为没有遗迹所以不可能在这个时期之后”的结论。
