Twelve years ago and again five years ago, there were extended periods when the Darfir Republic's currency, the pundra, was weak:its value was unusually low relative to the world's most stable currencies.Both times a weak pundra made Darfir's manufactured products a bargain on world markets, and Darfir's exports were up substantially.Now some politicians are saying that, in order to cause another similarly sized increase in exports, the government should allow the pundra to become weak again.

Which of the following, if true, provides the government with the strongest grounds to doubt that the politicians' recommendation, if followed, will achieve its aim?

(A) Several of the politicians now recommending that the pundra be allowed to become weak made that same recommendation before each of the last two periods of currency weakness.

(B) After several decades of operating well below peak capacity, Darfir's manufacturing sector is now operating at near-peak levels.

(C) The economy of a country experiencing a rise in exports will become healthier only if the country's currency is strong or the rise in exports is significant.

(D) Those countries whose manufactured products compete with Darfir's on the world market all currently have stable currencies.

(E) A sharp improvement in the efficiency of Darfir's manufacturing plants would make Darfir's products a bargain on world markets even without any weakening of the pundra relative to other currencies.

答案是B，但是我觉得B和结论无半毛钱关系啊

个人理解哈，一起讨论讨论

B的意思是说之前的low value使得出口上升的很快。那么工厂为了满足出口的上升必须加大生产。如果已经达到顶峰了，即使weak  pundra，出口也还是那么多而不会上升。

其他选项可以用排除法我觉得
A那些人之前两个时期就那么说了则代表那时候做法是有效的，加强了结论
C无关选项
D其他竞争国家价格稳定，则降价势必有出口优势，加强了结论
E无关选项，说生产效率上升使得DARFIR的产品有讨价还价的优势，有讨价还价优势与出口关系不知道。

要想论证的是，弱货币可以导致出口增加。那么灭掉这个结论，就要说明，弱化了货币也不会导致出口增加，B的意思是，出口生产受限制，因此没有了增加的空间，弱化货币也不会对出口有影响了

我觉得C不是无关选项啊，C说的是想要出口经济如果想要更加健康的话，那么货币就必须保持强势啊，这个难道不能削弱结论吗

(C) The economy of a country experiencing a rise in exports will become healthier only if the country's currency is strong or the rise in exports is significant.


C主要是在说明一个经历出口上升的国家经济能变得健康与国家货币的强度和出口上升的关系，但是本题叫我们对结论“采取以前的方法weak currency就能够增加出口”进行削弱。仔细看看，这两者之间有关系么。不要自己再增添信息到题目里。只能由题目里给的信息推结论。而且C选项着重说的是the economy of a country，而不是关于a rise in exports.所以说的是与国家经济相关，跟是否增加出口一点关系都没有。

哦，明白，谢谢了

请问各位，选项 (e) 为什么不能 doubt 原文？

原文说贬值，产品便宜了，会增加出口。选项 (e) 说提高效率的话，产品也会便宜，汇率无须变动。

就是还有另外的方法可以做同样的事情，而不一定要原文的方法。
