1. This questions is based on the article, "Signs of a slowdown," published by The Economist on June 6, 2015. The article discusses the trends in the value of the yen and its consequences during 2012 and 2015. The average annual rate of inflation during 2013 and 2014 was 1.55 percent in both the US and Japan.

By what percentage did the yen depreciate vis--vis the dollar in nominal terms in those two years? [4] By what percentage did the yen depreciate vis--vis the dollar in real terms in those two years?
