问题如下：
Exhibit 1
Exhibit 1 shows the supply and demand for money, There is an excess demand of money when the interest rate is:
选项：
A.I0.
B.I2.
C.I1.
解释：
B is correct.
If bonds offered an interest rate of I2, there would be an excess demand for money(M2-M0). Corporations and individuals would seek to sell bonds in order to increase their money holdings. So the price of bonds would fall and interest rate would rise until it reaching I0.
考点：MS & MD
解析： excess demand of money 是指货币需求MD超过了货币供给MS。
在本题中，水平方向上，MD＞MS所对应的点是I2点，因此应该选B
供给多的话，不就相当于需求少，MS小，竖线向左移动，所以选L0，为啥这样理解不对呢
