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.

这题的正确选项是B 看了笔记觉得可以理解但是我纠结的是C选项
题目问的是加强 C选项说的第一次交易到达该地的商品是最有价值的因此会被很好的保存以防止破损或者丢失我想说既然会被很好的保存就不会存在找不到的问题既然没有被找到就说明真的是因为当时就不存在不是刚好加强了追溯到不会晚于1630年的时间吗？
我一直觉得自己的思维很纠结...向请问各位大牛我这么想问题在哪里呢？

C貌似更像assumption

我也觉得c阿~~ 同求解~! >,<

非牛~~个人意见~

总觉得LZ想太多了吧。。。。
被很好的保存了可以说明找不到，但是有可能第一次交易的记录所证明的时间是晚于1630，比如说1640,1650？
那这样这个第一次的记录就没有什么意义了，也不能加强原文的结论 no later than 1630了啊~
相反B选项给出了明确的时间。。。。

总感觉CR的题不能想太多。。。要直接得出结论的那种。。。。

同意楼上,楼主想太多了,CR题不能深思考,在我看来C选项是个无关项,至少无法支持

FROM RON:

-----------------------
i can think of at least 2 reasons:

#1:

read the wording carefully: preserved as much as possible from loss or destruction

this statement carries no guarantee that 'as much as possible' will be successful in preserving those trade goods all the way to the present day, some four hundred years later. the trade goods could have been preserved as much as possible - in accord with this statement - and still disappeared before the present.

by contrast, there is no such problem with choice b, because that choice states that the goods 'have been found' at the sites (present perfect = this is a pattern that continues into the present)

#2:

'the first european trade goods to reach the area' may not have reached this particular camp.

quite clear and comprehensive~ Thanks a lot~

Addicted潇潇 · 发表于 2012-6-7 12:30:52

谢谢~

我也发现很多时候不能深想~ 但往往会克制不住自己~ 呵呵~

迷迭青 · 发表于 2013-6-23 15:18:55

楼主。。我俩的思维完全一样。。

joyce92pipi · 发表于 2013-6-23 21:19:27

我来试一下吧。
因：没有欧洲的goods 被找到；欧洲的traders很active
果：camp所以不会超过1630.

因果加强：
1.加强因果联系
2.特殊因素

a. 欧洲会在trader到之前就到了。削弱因果联系阿
b.所有1620的camp，都会发现欧洲的货物。
c.货物有没有价值的问题，跟因果结论没啥关系吧？
