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

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

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

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

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

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

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

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

我自己选了E，看了解释，答案是B。不是太理解！跪求牛解释啊！

B项说产能已经接近饱和，即使降低currency也不会促进export，因为没有更多产品可供出口了。从而weaken了那些politician的建议。
