25.   (30261-!-item-!-188;#058&004144)

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.是以前还有增长的空间，现在已经到顶了?

(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.

 我选的是E,但答案是B.不太明白B的意思,还有为什么E不对?谢谢.

lz对B的理解是对的，现在产量到顶了，再incent export都是没用了...

E只是解释了efficiency上升，会造成 Darfir's products成为a bargain的一个过程。对原文没有任何的削弱，支持关系。 应该说只是原文的principle改写罢了...

我感觉问题出在题干所问的问题，问的是政府对政治家的建议有效性（是否能达到目的）的质疑。政治家的建议的目的是为了达到相似的出口增量，方法是必须通过弱化本国货币。而E表达的是政府觉得现在的产品因为效率提高所以相对价格低廉，已经能够满足条件达到相似的出口增量——这里变成政府觉得没有必要follow该建议，但题目问的时候加了一句if followed，也就是已经假定了前提是follow这个建议，问效果是否能达到。

所以E是提供了跟原题假设前提完全相左的前提，不能够造成削弱。outside the scope

而B是即使follow了该建议也不能达到预期出口增加的效果，因为出口量已经到顶了。削弱了政治家的结论。
