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: 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.
C: The value of Argonia's exports was lower last year than it was the year before.
D: 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.
