问题如下：
Wakuluk is most likely to make signifcant adjustments to her estimate of the future growth trend for which of the following countries?
选项：
A. Country Y only
B. Country Z only
C. Countries Y and Z
解释：
B is correct. Country Z is a developing market. Less-developed markets are likely to be undergoing more rapid structural changes, which may require the analyst to make more signifcant adjustments relative to past trends.
解析：本题中提到Z国是一个发展中市场。欠发达市场可能会经历更迅速的结构性变化，这就要求分析师相对于过去的趋势做出更重大的调整。所以本题只有B是正确。
题干是Y move into next economy cycle，这样不是也需要调整预期的嘛？
