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.

OA:B

各位大神，这个题我不太理解B的意思。看了一些网站的解释也没理解透。After several decades of operating well below peak capacity, Darfir's manufacturing sector is now operating at near-peak levels 这句话的意思怎么理解比较好？我能理解如果该国的出口能力已经达到上限，货币再贬值也没用。但是B选项貌似不是这个意思？产能接近峰值了，那么正好可以多出口呀？

谢谢！

货币贬值，那本国企业就要花更多钱进口更少钱出口，所以进口减少，出口增加，但出口增加是要增加生产的。这句话是说如果产能到峰值，那么贬不贬值就刺激不了出口了。因为商品就用来出口和国内售卖，产能峰值了数量就不变了，出口也不变了。

politicans' argument是不是说，现在如果让货币贬值，将会带来和以前一样的大幅度出口增长，B选项是说，现在产能已经到顶峰了，即使货币贬值，产能也无法支持出口大幅增长。
