问题如下：
Based upon the following data, which country is expected to be assigned the lowest sovereign credit rating?
选项：
A.Costa Rica
Dominican Republic
El Salvador
解释：
C is correct.
El Salvador is expected to have the lowest credit rating due to its high long-term external debt-to-GDP ratio. While the Dominican Republic has lower currency reserves than El Salvador, it also has a lower external debt burden and higher economic growth.
currency reserves是EI Salvador高而Dominican低，而Long-term external debt/GDP又是相反，考试中如何判断哪个国家信用好呢？如果按照对信用的影响程度，这三者怎么排呢？原版书或者讲义上有没有对应的部分？
