考古学家在密西根的Dumaw Creek附近发现了印第安人的营地.在营地里发现的兽骨中的放射性碳显示这个营地起源于1605和1755之间.然而,这个营地不会晚于1630,因为在这里没有发现欧洲的贸易品,并且欧洲的商人从1620年代开始在这里很活跃.

加强题..

B. 16世纪20年代后期,在这个区域内的所有的营地都发现了欧洲贸易品.

以前没有,而之后全都有..那肯定是以前建立的营地..显然是加强..

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.
