24-14: In 1983 Argonia’s currency, the argon, underwent a reduction in value relative to the world’s strongest currencies. This reduction resulted in a significant increase in Argonia’s exports over 1982 levels. In 1987 a similar reduction in the value of the argon led to another increase in Argonia’s exports. Faced with the need to increase exports yet again, Argonia’s finance minister has proposed another reduction in the value of the argon.

Which of the following, if true, most strongly supports the prediction that the finance minister’s plan will not result in a significant increase in Argonia’s exports next year?

A) The value of the argon rose sharply last year against the world’s strongest currencies.

B) In 1988 the argon lost a small amount of its value, and Argonians exports rose slightly in 1989.

C) The value of Argonia’s exports was lower last year than it was the year before.

D) All of Argonia’s export products are made by factories that were operating at full capacity last year, and new factories would take years to build.

E) Reductions in the value of the argon have almost always led to significant reductions in the amount of goods and services that Argonians purchase from abroad

答案为D。偶好晕，一点儿背景知识都没有，还是不用背景知识也可以解这道题？ 谢谢xdjm们

你可以使用很多以前经典的逻辑方法进行做题;

这里偶主要还是想说一下, 不需要任何背景, 偶也不关心背景知识;

1987年前后(虽然1987之前有两次行为,但跟一次没什么区别)的差异; 如果两个时间段的其他条件都是相同或者相似的,那么就是加强, 只要存在差异,那么就达到削弱的目的;

其实这个题跟之前之后没有什么关系。

D说，去年所有的工厂已经满负荷运转了，而新工厂要花好几年才能建成。

实际上明年出口不可能再增长了。你货币跌倒0也没用。

所以这个是他因削弱。
