问题如下：
One of the reasons aggregate demand curve is downward sloping is because a lower price level means that the real exchange rate:选项：
A.depreciates, making domestic goods cheaper in other countries and imports less competitive, resulting in a higher level of net exports. B.appreciates, making domestic goods more expensive in other countries and imports more competitive, resulting in a higher level of net exports. C.appreciates, making the country’s exports and imports less competitive and leading to lower net exports解释：
A lower price level results in a weaker real exchange rate, making domestic goods cheaper to people in other countries and imports less competitive, resulting in a higher level of net exports.
中文解析：
较低的价格水平导致较弱的实际汇率，使国内产品对其他国家的人来说更便宜，进口产品的竞争力下降，导致净出口水平上升。
为什么上一题才说了demand curve is downward 的话 interest rate是增加的？汇率是下降的？
