题目：
Which of the following factors is most likely to increase aggregate demand（）
A. Increasing real interest rates.
B. An expected decrease in future prices.
C. An increase in real wealth.
答案：
参考答案：C
解析：
While an increase in real wealth will shift the AD curve to the right, an increase in the real rate of interest will shift the AD curve to tile left as consumers and businesses reduce their borrowing and spending. An expected decrease in prices will shift the AD curve to the left as households and businesses postpone their consumption in anticipation of lower prices in the future. An expected decline in profits will cause firms to decrease investment.
