标题: 牛人帮忙看一道CR 急啊

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.
这题正确选B。来看下C为什么不对呢？
C说第一批文物会保护很好不受损失。那结合原文，不可以这样理解吗，因为第一批不会受损，所以因为没有发现文物，说明确实第一批没有来这个camp, 所以这个camp一定是在第一批来之前就已经废弃了。这camp年代肯定在第一批1620之前。
我的这种思路为什么不对呢？
