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?

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

2. In 1988 the argon lost a small amount of its value, and Aronian exports rose slightly in 1989.

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

4. 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.

5. 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.

答案是D，可就是不明白什么意思啊，D中的new factories would take years to build和currency有什么关系？

 The argument says that "reduction in the value of the argon led to  increase in Argonia’s exports"

The question want us to prove that "the finance minister’s plan will
                not result in a significant increase in Argonia’s exports next year?"

D says "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"  That is, it is impossible to increase export next year.

Hence, D is the answer.
