请教各位大侠，对Prep1-25 的疑问

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.

(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.

why the answer is B. May i misunderstand the meaning of this Question! Please help me out, thanks

no anwer

答案是B

题目大致是说,12年前跟5年前,在两次时间里,Darfir Republic 的货币(currency)两次贬值, 由于贬值引起他们的出口大大地上升.结论,为了再一次促进出口的上升,D 国家的政客打算再次让货币贬值.

问题是问,如何削弱这些政客的建议.

B,说到,他们国家的生产能力(capacity)已经接近peak levels. 换句话说,就是再怎么贬值刺激他们, 所能生产的products数量也不会在提高, 从而出口也不会增加.

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.

12年前以及5年前，Darfir's的货币疲软，导致其出口的迅速上升。政治家们说为了使出口再一次上升，国家应该鼓励货币疲软。

文章推理：货币疲软导致出口

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.

只是说政治家们做了同样的决定，重复前提

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

正确，商家已经达到顶峰，已经没有可以增加的余地了。就算是疲软，出口也不会增加

(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.

和国家的健康发展无关，结论讨论不能增加出口

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

和其他国家的货币无关，重复前提

(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.

反对前提，文章讨论货币和出口的关系，属于张冠李戴
