46.(33987-!-item-!-188;#058&007200)

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.

题目要求是strengthens the argument，意思是加强‘the camp dates from some time between 1605 and 1755’？
所以B选项的内容否定了‘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.’
使‘the camp dates from some time between 1605 and 1755’得到了加强.
请问是这样的推理过程吗??
谢谢！！！

同问  既然最后一句说了since no European trade goods were found at the site， 为什么b答案又有那些东西呢，到底要加强的是哪部分？求解！

counyo

要加强the camp probably dates to no later than 1630，since后面是一个evidence来support这个argument

问题是要你用另外一个evidence来支持the camp probably dates to no later than 1630
