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 connection between "trade goods came to the area" and "trade goods came to this camp".注意区分camp和region，traders在这一块区域内活动，不代表每一个camp都会有goods，这是一个weaken，反过来，要是说每个camp都有goods，这就是strengthen
B. The argument says that the camp is pre-1630 since there were no European trade goods. The gap in logic is that anything that is post-1630 must have European trade goods
C. Just because they were preserved by those who had them, doesn't mean all would have them.
C选项，即使第一个没被保存下来没事，欧洲人如果真的来过，那一定会留下些东西作为痕迹，但既然一点都没有，就说明真的就没来过，所以不能strengthen
