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.

[url=](B)[/url]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.

这道题选B。

我觉得做CR题思路最重要，所以我先说说我的思路，请大家纠正我的思路帮助俺进步  ORZ
这道题简单来说就是：曾经weak currency——>increase export，于是conclusion：politicians 建议再weak currency——>increase export。若要weaken此逻辑链，只需找到其他新的条件来割断weak currency和increase export之间的因果关系即可。
我选的是E，我觉的E选项对是因为提供了他因或者也可以说是新的情况——自身制造业的生产效率提高使得D的产品在世界市场上（也就是export）价格上具有优势，even without weakening of the currncy。这不就是很好的割裂了weak currency和increase export之间的联系吗？如果说这个选项有问题的话，是不是因为这里只说的是bargain而没有推到export？但是我觉得似乎这俩在文中就是一个层面的事了。
但是我觉得B比E更加不靠谱，因为B只说明了他的制造部门也就是产量达到了峰值从而暗示无法再增加产量了，但是这个没有直接推到export啊，一个国家的产量可以内销也可以出口，即便总量一定，但也不代表出口量也一定不变啊？
