问题如下：
6. Which of the following statements given by Trainee #1 in describing the approaches used by CGER is most accurate?
选项：
A.Statement 1
B.Statement 2
C.Statement 3
解释：
C is correct.
The External Sustainability Approach deals with stocks (i.e., levels of) outstanding assets or debt and the financial flows associated with the capital account. The comment correctly states the External Sustainability Approach focuses on adjustments resulting in long-term equilibrium in the capital account.
考点：这道题的内容虽然考纲上删除了，但是在原版书课后题还是有的，所以我们还是要掌握三个模型的特点。
解析：C选项的说法是完全正确的，External Sustainability Approach 更加关心资本账户的情况。
A选项说法错误在于 Macroeconomic Balance 并不过于关注资产以及负债，它主要关注的是进出口经常账户的状况。
B选项的说法错误在于 Reduced Form 对于预测汇率被高估或者低估方面不存在劣势，这是题目杜撰出来的选项。
这个题目没有在原版书上面找到呀？
老师上课强调这个知识点了么？
