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?  削弱

(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.无关

(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.无关

(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.

答案居然是b,不能理解，此题不就是削弱the politicians' recommendation？非a ---b这种削弱方式不对吗？ b 达到了peak capacity 有什么逻辑关系，期待妞妞解答，谢谢先

谢谢  真是好人

我还不是很信服，因为汇率下降可以使得价格降低，这样使得产品在国际市场有竞争力，出口上升；

B说明生产能力不会有显著提高，和价格无关啊，

如果选B就是默认了出口量有两个因素：价格和产品数量，那么这次只能保证价格优势，但是出口数量没有前面的多。

这道题目很早以前就在gwd和og上出现过了，只不过名字稍微改了一下而已。答案确实是B，解释如下：由于该国的生产能力已经接近峰值，所以即便货币继续贬值，由于已经没有剩余的产能了，所以出口也不会再提高了。换句话说，就是现在已经把能卖出国的都卖了，你的钱再不值钱也没用了，因为都没什么东西可以卖了。
