问题如下：
If the domestic currency depreciates, what will be the effect on a direct exchange rate?
选项：
A.Decrease
B.Increase
C.No change
解释：
B is correct
For a direct exchange rate, the domestic currency represents the price currency and the foreign currency represents the base currency . If the domestic currency depreciates, then more units of the domestic currency are need to buy certain mount of foreign currency, So the exchange rate will rise.
考点： direct exchange rate
解析：对于直接汇率，本币代表价格货币，外币代表基准货币。如果本币贬值，那么就需要更多的本币才能购买一定数量的外币，汇率就会上升。
以RMB USD表达为例：
6.9RMB/USD中，USD是价格货币也就是本币，RMB是基准货币也就是外币。本币贬值也就是USD贬值，6.9这个数值应该会变小不是吗？？？？
