OG12-Diagnostic Test-21

ttss

一道OG诊断测试部分的CR题，没有搜到旧帖，大概比较容易吧- -|||  如下：

21. Metal rings recently excavated from seventh-century settlements in the western part of Mexico were made using the same metallurgical techniques as those used by Ecuadorian artisans before and during that period. These techniques are sufficiently complex to make their independent development in both areas unlikely. Since the people of these two areas were in cultural contact, archaeologists hypothesize that the metallurgical techniques used to make the rings found in Mexico were learned by Mexican artisans from Ecuadorian counterparts.


Which of the following would it be most useful to establish in order to evaluate the archaeologists’ hypothesis?


(A) Whether metal objects were traded from Ecuador to western Mexico during the seventh century
(C) Whether artisans from western Mexico could have learned complex metallurgical techniques from their Ecuadorian counterparts without actually leaving western Mexico


答案是A，我选的C...看了解释后大致明白了为什么是A，但是对C又说不出理由来。。而且OG的解释是认为有了metal objects的贸易后就可能把技术也传过去，那为什么不能认为像C项那样，是有厄瓜多尔的同行直接过来教了呢。。该怎么排除C项？

顺带附上OG的解释，还请达人解答！谢谢！
Argument Evaluation
Situation Metal rings excavated from seventh-century settlements in western Mexico were made with the same complex techniques used in Ecuador before and during a period when the two cultures were known to be in contact. Mexican artisans are thought to have learned the techniques from Ecuadorian artisans.
Reasoning What point could best be applied in evaluating this hypothesis? Consider what specific information would help to assess the archaeologists’ theory. It is given that the two areas had some cultural contact. If it were determined that metal objects were traded from one culture to the other, it could be possible that the metalworking techniques were passed along as well. Such evidence would be relevant to the hypothesis that Mexican artisans saw the work of their Ecuadorian counterparts and, from this exchange, learned the techniques to make the metal rings.
A Correct. Th is statement properly identifies information that would be useful in the evaluation of the archaeologists’ hypothesis.
C The hypothesis is not about where Mexican artisans learned the techniques, but whether they learned them from the Ecuadorians.
The correct answer is A.

求救~~~我对这道题也有疑问。跟楼主的好像不一样。原命题是：墨西哥人从厄瓜多尔人那里学到了metallurgical ...

我也这么觉得，觉得OG解释很牵强

求救~~~
我对这道题也有疑问。跟楼主的好像不一样。
原命题是：墨西哥人从厄瓜多尔人那里学到了metallurgical技术并制造了这种金属指环。
问得知哪个选项的知识有助于评价此假设。
A选项说，17世纪有没有从厄瓜多尔贩卖到墨西哥的金属物件。
我也觉得应该选A，但我跟答案想的相反。答案认为如果有的话加强，无的话削弱，因为金属的贩卖可能伴随技术的传播。我认为有的话减弱，无的话加强，因为如果当时有贩卖，那么墨西哥出土的金属指环就不一定是墨西哥人自己做的了，可能是从厄瓜多尔运来的。
我这个想法有没有道理呢？做阅读是不是不应该用这种逻辑呢？OG里有好几道题都觉得答案是对的但解释我不认同，OG的出题人和编解释的人是同一个吗？

分析的精辟啊！偶也选错了~

谢谢，我也明白了点了

呵呵，明白了就好~可能我的表达不太清楚~呵呵！LZ应该是把加强当做是充分条件了吧？其实不是的，加强不是原命题的充分条件！不能直接退出原命题成立，只能使得原命题更加有可信度！我觉得LZ可能是在不停地举反例来削弱加强的条件吧？呵呵！加强的条件不是无懈可击的啦~

这条真说对了！我明白了~~~~谢谢~！！

还有，这道题目，就算还有别的国家传入的可能，依然不影响A的加强作用。因为A说了7世纪从E肯定传过来了，那么至少是问E国学习的可能性就大了，就是加强~~~至于别的国家有没有传过来无所谓！又不是要找可能性最大的国家，哪怕本来厄瓜多尔的可能性是1%，现在A选项让他变成了2%，也是加强！！！不是说加强就让他变成100%了！
