46. (33987-!-item-!-188;#058&007200)

Archaeologists in Michigan haveexcavated a Native American camp near Dumaw Creek. Radiocarbon dating of animal bones found atthe site indicates that the camp dates from some time between 1605 and 1755. However, the camp probably dates to no laterthan 1630, since no European trade goods were found at the site, and Europeantraders 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 NativeAmericans, some European trade goods would have reached the area before theEuropean traders themselves did.

(B) At all camps in the region thathave been reliably dated to the late 1620's, remains of European trade goodshave been found.

(C) The first European trade goodsto reach the area would have been considered especially valuable and preservedas much as possible from loss or destruction.

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

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

我的思路是这样的：C说欧洲货物都非常值钱且尽可能保存了，那么可以推出有goods的就是no later than 1630的，没有goods的就是1630以后的，这样就strengthen了原有argument。请问NN，我的思路错在哪里呢？谢谢！

我自己的理解：B说了At all camps...意思是说只要是追溯到1620‘s的camp,就一定可以找到欧洲人的货物。这个条件很强，意思是说没有没有找到欧洲人货物的camp，就一定不能追溯到1620s，所以B强烈strengthen了argument。
而C知识一个旁证，也有可能尽力保存但仍然没有保存下来，所以C不一定能帮助加强argument，因为没有发现可能是因为没有保存下来。
