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.

 

这个题目选B 我也在网上找了下解释  可是还是没看懂
哪位可以好心帮我翻译下题目再解释下答案吗？ 那个DATE TO的东西真搞不清楚是之前还是之后
先在此谢过啦···

人类学家在密歇根Dumaw Creek附近发掘了一个印第安的营地，营地发现的兽骨的放射性碳试验表明这个营地始建于1605到1755之间。但是这个营地绝不会晚于1630，因为在营地内没有发现欧洲的舶来品---欧洲的倒爷从16世纪20年代以后在这一地区很火。

a，一些欧洲舶来品会流散到欧洲倒爷没到达的地方

b，所有这一地区16世纪20年代以后的印第安营地里都发现欧洲舶来品

c，第一品欧洲舶来品到达的不拉不拉，无关项，看不下去。。

d，无关

e，什么临时营地，季节性被使用，无关

营地没有欧洲舶来品+20年代以后的营地都有舶来品，所以能加强结论：这营地应该建于1630年以前。

哈哈  非常感谢啦~~~~

我当时觉得如果题干说是不会晚于20s会比较好 后来一想 可能30s也差不多 哈哈

对B没有疑问 但E有些不明白 E错是因为没有与1620这个数字建立起联系所以无关么？

camp date between 1605 - 1755                                    no European trade goods were found+E traders were active before 1620's-->camp dates before 1630 (B)all remains of E trade goods have been found in late 1620's

是推翻的题目原本叙述no European trade goods were found ???

所以 remains of E trade goods have been found in late 1620's+E traders were active before 1620's-->camp dates before 1630???
