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.
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。
