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.

 

考古学家在密歇根发现了一处遗址，根据激光显示这处遗址应该在1605到1755期间。但是实际上应该不晚于1630，因为在遗址中没有发现欧洲的交易品，并且欧洲交易在1630以后才发生在这一区域。

 

没有欧洲交易品推出不晚于1630

 

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.

和这个区域并没直接的关系

(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.

正确，在1620年后的遗址中，欧洲商品就出现了。属于异因异果。

(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.

和欧洲商品的价值无关，和遗址没有关系

(D) The first European traders in the area followed soon after the first European explorers.

和欧洲商人什么时候进入无关

(E) The site is that of a temporary camp that would have been used seasonally for a few years and then abandoned.

并不能加强1620这个年代

我不明白,为什么没有欧洲货,就说CAMP一定是在30年前形成的呢? 是否说如果有了欧洲货,就可以是30年后的呢,但是欧洲货不是1620年来的吗，为什么不说是在1620年前的．　

1620-1630间有什么因果

(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. 1620年之后的就都发现欧洲人的东西，强烈对比，说明没有发现的就是没有欧洲人

(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. 并没有排除就没有保存下来的可能，不是很好

题目假设的关键是：
        欧洲货的出现和欧洲人出现有必然联系

(A) Due to trade among Native Americans, some European trade goods would have reached the area before the European traders themselves did.  没有欧洲人来之前它们之间也会交易，能否发现欧洲货和年代无关，削弱了原文，否定了题目假设

(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. 1620年之后的就都发现欧洲人的东西，强烈对比，说明没有发现的就是没有欧洲人的年代。肯定了题目假设

(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. 并没有排除就没有保存下来的可能，而且没有说明是否欧洲货出现和欧洲人出现的时间有必然联系，也有可能是native自己倒卖过来的啊，那就和A一样错误了

题目的意思是说1620前有这些东西,1620年后没有,B直接说出了这一点.

A只说了可能有,但是没有说明确的时间,不如B那样明确和坚决(all)

对於17楼的老兄，您所说的应该是1930後没有吧，题目时间焦点是以1920~1930当范围的

hsuanhao

对不起手误，应该是1620~1630

同意8楼对c的说法， 我也是觉得 “would have been“ 很能说明问题。
