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.
preserve sth from ……，保存/保护某物使其免于
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.第一个到达的欧洲商品会被认为尤其珍贵，被尽可能地保护，以免于损毁。
Michigan的考古学家在Dumaw Creek发掘了一座美国原住民曾经生活过的的遗址。追溯动物骨头上的放射性碳元素表明这处遗址大约是在1605年到1755年之间。但是，这处遗址应该是在1630年之前的，因为1620年以后，欧洲的贸易商人在这一带就很活跃，但是这一带并没有发现有欧洲的贸易商品。
问加强。
B从1620年开始就有生活痕迹的所有地区，我们都能找到欧洲商品的遗迹
C第一个欧洲商品到达当地时，它一定是非常有价值并且会被保存起来免受侵害的
