Economist: The economy of the Republic of Nantau has experienced lower than expected growth in the past year, and the value of its currency has dropped against the Yen. As a result, purchases of imported goods, such as usually luxury items or high-end electronics, will likely decrease as people turn to cheaper domestic equivalents. However, this will likely help reverse the negative economic trends by creating a trade surplus as export goods become cheaper.

(D) The first provides evidence to support a prediction that the argument seeks to defend; the second is that prediction.
