Commemorative plaques cast from brass are a characteristic art form of the Benin culture of West Africa. Some scholars, noting that the oldest surviving plaques date to the 1400s, hypothesize that brass casting techniques were introduced by the Portuguese, who came to Benin in 1485 A.D. But Portuguese records of that expedition mention cast-brass jewelry sent to Benin's king from neighboring Ife. So it is unlikely that Benin's knowledge of brass casting derived from the Portuguese.

Which of the following, if true, most strengthens the argument?

Commemorative plaques cast from brass are a characteristic art form of the Benin culture of West Africa. Some scholars, noting that the oldest surviving plaques date to the 1400s, hypothesize that brass-casting techniques were introduced by the Portuguese, who came to Benin in 1485 A.D. But Portuguese records of that expedition mention cast-brass jewelry sent to Benin’s king from neighboring Ife. So it is unlikely that Benin’s knowledge of brass casting derived from the Portuguese.

Which of the following, if true, most strengthens the argument?

A.        The Portuguese records do not indicate whether their expedition of 1485 included metalworkers.
B.        The Portuguese had no contact with Ife until the 1500s.
C.        In the 1400s the Portuguese did not use cast brass for commemorative plaques.
D.        As early as 1500 A.D., Benin artists were making brass plaques incorporating depictions of Europeans.
E.        Copper, which is required for making brass, can be found throughout Benin territory.

ans. B

無法理解B為什麼正確?然後也想請問C錯在哪裡
謝謝~

很精彩的一道题,经历了一些思考后写下自己的理解,可能会比较费时。
通过选项B来透视过程:
确定的时间线:公元(注意不是公元前)1400-1499年B国有了铜物件---1485年P国人到访---1500年后P国与I国才建交---建交后才记录了铜首饰从I国贸易到B国
反向论证:如果1485年冶铜工艺就已经从P国传到B国,那B国就不会从I国买入铜首饰;与事实相反,所以假设不成立,即冶铜工艺不是(1485年)从P国传到B国的
精彩点:不要纠结冶铜工艺的来源,题目只是确认P国没有扮演工艺输出者的角色
另外,有一个必要的假设:能做铜物件的B国是可以自产铜首饰的。

  1. A.无关选项,因为1400年就有plaques了,1485年带没带工匠就不重要了。

我跟层主理解的不太一样,也可能是我中文不好。

首先不是1400年,而是1400s. 1400s refers to the period from 1400 to 1499, almost synonymous with the 15th century (1401 to 1499) ---- from wikipedia.
证据关于在1485A.D.有没有metalworkers很重要。

A. The Portuguese records do not indicate whether their expedition of 1485 included metalworkers.
records既没有说有metalworkers也没有说一定没有metalworkers,基本就是没有提关于metalworkers。所以这个选项不能strengthen or weaken the argument.

如果A写成"The Portuguese records indicate that their expedition of 1485 did NOT include metalworkers. 这是strengthen the argument. 反之,weaken。

A.无关选项,因为1400年就有plaques了,1485年带没带工匠就不重要了。
B.正确,如果葡萄牙人没有和Ife的交流,那么Ife的传到Benin的技术肯定就和葡萄牙无关了。所以加强了观点。
C. 这个选项不能算完全错误,毕竟gmat不是一个完美性的测试,但是它以偏概全了,不会使用brass for commemorative plaques不能推出不会brass-casting techniques。
D.1500年发生的事情已经不重要了
E.能找到原材料不一定和技术有关,无关选项

希望能帮到楼主

结论:贝宁人的brass-casting技术不大可能来自葡萄牙人
文中已说 葡萄牙人记录中贝宁人的铜首饰来自隔壁的Ife,如果葡萄牙和Ife直到1500s才有来往,那贝宁人的冶铜技术更可能来自邻居Ife而不是葡萄牙人,这不就进一步增强了作者的观点了

C错得很明显啊,In the 1400s the Portuguese did not use cast brass for commemorative plaques不等于葡萄牙人在1400s没有brass casting技术(有可能只是还不会做纪念碑啊),如果有这技术,这不就weak了作者的结论了

不知道说得对不对,共同探讨下
