问题如下：
What will be the effect on a direct exchange rate quote if the domestic currency appreciates?
选项：
A.Increase
B.Decrease
C.No change
解释：
B is correct.
In the case of a direct exchange rate, the domestic currency is the price currency (the numerator) and the foreign currency is the base currency (the denominator). If the domestic currency appreciates, then fewer units of the domestic currency are required to buy 1 unit of the foreign currency and the exchange rate (domestic per foreign) declines. For example, if sterling (GBP) appreciates against the euro (EUR), then euro–sterling (GBP/EUR) might decline from 0.8650 to 0.8590.
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。如果本币升值，那么需要更少的本币就能购买一定数量的外币，汇率就会下降。
老师，针对何老师在Interest rate parity视频中11:36提及的知识点，当rate A大于rate B时，即期货币A是升值的。。。跟这题中的答案是相反的，要怎么理解哦？概念有点搞脑子。。。望指导，谢谢。
