问题如下：
There are some limitations when using the cyclical/ non-cyclical descriptive approach to classifying companies. Which of the following is not one of these limitations?
选项：
A.Two cyclical companies operating in different countries may be experiencing different cyclical stage.
B.Business-cycle sensitivity is more like a discrete phenomenon instead of a continuous spectrum.
C.Cyclical company may contain growth behavior.
解释：
B is correct.
Firms can be classified by their sensitivity to the phase of the business cycle. So the business-cycle sensitivity is a continuous spectrum phenomenon instead of a discrete one.
C也是错的吧，成长性行业应该包含在非周期行业里
