问题如下：
In explaining the downward slope of the aggregate demand curve, the interest rate effect suggests that a higher price level will:
选项：
A.lead to lower interest rates, which will lead to higher levels of consumption and investment.
B.lead to higher interest rates, which will lead to lower levels of consumption and investment.
C.not affect interest rates and therefore will lead to a higher level of aggregate demand.
解释：
B is correct. Given the fixed money supply, a higher price level leads to a higher money price.Since the interest rate is the price of money, as the price level rises, so will the interest rate.Consumption and investment fall as interest rates rise
老师好，这道题我有2个疑问
1. 这里的利率是不是指实体经济投资的利率（比如企业家投资设备厂房等），不是指金融工具的投资（比如股票债券）？
2. 价格和实体经济投资利率的关系能不能这样理解：价格上升代表出现通胀，此时为了解决通胀，人行会制定紧缩的货币政策，上调实体经济投资利率，最终导致利率上升
