问题如下：
To better advise the firm’s clients on the likelihood of
currency crises, Analyst Kwantries to formulate an early warning system for the
episodes of currency crises. She recognizes that a typical currency crisis
tends to be triggered by a number of economic problems, not just one.
选项：
A.correct
incorrect, because
there are few historical crises involving currencies of countries with sound
economic fundamentals
incorrect, because
there are few historical episodes in which a sudden adverse shift in market sentiment
occurs that is unrelated to economic fundamentals
解释：
Even countries with sound economic
fundamentals can be subjectto a currency crisis, including instances when
market sentiment shifts for noneconomic reasons.
解析：即使那些经济基本面良好的国家也可能遭遇货币危机，包括市场情绪因非经济原因而发生变化的情况。因此只有A选项是正确的。
economic problems仅仅指经济基本面相关的因素，还是包括市场情绪等非经济因素？
1.如果a number of economic problems包含非经济因素，那么A选项没有问题，但是economic的表述就很容易混淆；
2.如果a number of economic problems仅仅只包含经济基本面因素，那么A选项也不正确。
感觉题干表述有点迷惑。
