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.
politicians 依据的前提是a weak pundra made Darfir's manufactured products a bargain on world markets, and Darfir's exports were up substantially. Weaken 题目正确选项从来不会攻击前提，前提都是默认为真的。因此在寻找正确答案时，一定要找可以攻击到推理链的，不要找直接攻击前提的。 我认为E选项直接攻击了前提，即存在其他条件使得即使pundra不贬值Darfir的出口仍能获得成功。 而选项B直接攻击了推理链。即使pundra贬值可以使得出口获得成功，但是制造业产能已近顶点，使得结论的可能性减低。
原文逻辑链是这样的a weak pundra 导致export是上升 (B) After several decades of operating well below peak capacity, Darfir's manufacturing sector is now operating at near-peak levels.
