A. ①
B. ②
C. ③
答案
参考答案：A
解析：
At higher price levels, consumption, investment, and net exports all decrease. A rising price level decreases consumers’ real wealth, so they consume less. The higher price level will increase interest rates, which causes business investment to decrease. Rising domestic prices will also reduce foreign purchases of the country’s goods, decreasing net exports.
