问题如下：
A country that maintains a target exchange rate is most likely to have which outcome when its inflation rate rises above the level of the inflation rate in the target country?
选项：
A.An increase in short-term interest rates.
B.An increase in the domestic money supply.
C.An increase in its foreign currency reserves.
解释：
A is correct.
Interest rates are expected to rise to protect the exchange rate target.
目标国的通胀上涨会导致本国的汇率上升。通胀上升会导致本国货币贬值，为了保证本国货币不贬值，必须实施一个紧缩的货币政策。
A选项提高短期利率入选。
B选项增加货币供给是一个扩张的货币政策，利率下降，不入选。
C选项增加外汇储备和本题无关。不入选。
老师请问这道题是在问inflation高于target inflation的结果（通胀导致本币贬值、市场上流通本币过多、利率下降）还是面对这个结果应该的解决措施（紧缩型货币政策）？
