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?
Due to trade among Native Americans, some European trade goods would have reached the area before the European traders themselves did.
At all camps in the region that have been reliably dated to the late 1620's, remains of European trade goods have been found.
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.
The first European traders in the area followed soon after the first European explorers.
The site is that of a temporary camp that would have been used seasonally for a few years and then abandoned.
A：可能有一点点加强，但不如B（fills in a needed assumption; 原文的gap在于 没有被找到=原来不存在）
C：原先的人们保存的很好≠ 直到现在也保存的很好；reach that area ≠ that camp
