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
(B) Whether travel between western Mexico and Ecuador in the seventh century would have been primarily by land or by sea
(C) Whether artisans from western Mexico could have learned complex metallurgical techniques from their Ecuadorian counterparts without actually leaving western Mexico
(D) Whether metal tools were used in the seventh-century settlements in western Mexico
(E) Whether any of the techniques used in the manufacture of the metal rings found in western Mexico are still practiced among artisans in Ecuador today

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. This statement properly identifies information that would be useful in the evaluation of the archaeologists’ hypothesis.
B The means of travel is irrelevant to the hypothesis about the source of the techniques.
C The hypothesis is not about where Mexican artisans learned the techniques, but whether they learned them from the Ecuadorians.
D The existence of metal tools provides no helpful information in establishing whether the Ecuadorians were the source of the metallurgical techniques.
E The comparison to the present day is irrelevant to the hypothesis.

The correct answer is A.

我的选的是D，但是在我选的时候，我自己就给自己找到反例了。即使有工具，也不能说明是墨西哥人用的，就更不能说明是墨西哥人从厄瓜多尔人那里的学技术，再用这技术自己制造metal ring. 但是，我找不出更好的答案了，就选了这个答案。错了。

我对A支持结论，如果不看答案，真是一点感觉也没有。这是在验证确实在cultural contact 中，有mental trading 这样的事情存在。

不是很了解什么叫加强条件。请大家帮帮我这个逻辑盲吧

A解释的是"墨西哥人从厄瓜多尔人那里的学技术"还是"厄瓜多尔人从墨西哥

人那里学的技术“.........= =!

D不用解释了吧， metal tool是不是用在两国的清算中和技术是从哪儿方传给

哪儿方的没关系吧。。。。

题目提供了三方面信息：
1\Conclusion: archaeologists hypothesize that the metallurgical techniques used to make the rings found in Mexico were learned by Mexican artisans from Ecuadorian counterparts
2\Reason： the people of these two areas were in cultural contact
3\Fact： 从 W.M，seventh-century settlements 中挖出来的metal rings制作技术和差不多那个时期的 Ecuadorian artisans 使用的技术一样（另外强调了技术的复杂性和唯一性）
原因里说的cultural contact没有明确具体发生时间
A选项，明确了原因中的cultural contact是两个地区之间的trade，且from E to W.M。更关键的是点明时间seven-century。
如果trade不发生在挖出来的metal rings被埋的seven-century，就是weaken；反之就是strengthen。

个人愚见。还请各位NN指点。

恩恩。这个解释很好，我接受。

这个题其实就是想一想 “如果不是墨西哥人从亚洲人那里学习的”，还有其他方法可以让两个地区同时出现这一种技术吗？

A的意思正好吻合这个假设 “即便不是学来的，也可以是贸易来的”学习和贸易就是两个对立面

没有削弱或者加强的意思层面，只是排除其他原因
