问题如下：
6. After Regulation Q was imposed, the demand for money market funds most likely:
选项：
A.increased.
B.decreased.
C.remained unchanged.
解释：
A is correct.
Regulation Q set a ceiling on the interest rates paid by banks for various types of deposits, which resulted in investors’ shifting funds to money market funds.
考点： Analysis of Regulation
解析:货币市场和银行储蓄市场是两个市场。Regulation Q使得银行储蓄利率不能超过某个临界值，是针对储蓄市场而言的，所以会降低投资者的储蓄比重。鉴于此人们会把更多的钱用来买货币基金（比如国债等，不包含储蓄），因此会使货币基金的需求量上升。
蒙对的，可以理解为，对银行有准备金的上限要求，是促进市场货币流通的一个举措吗？
