ff the economy is just beginning to come out of a recession, which of the following would represent a typical sequence of phases in the business cycle（）
A. Expansion, business peak, contraction, recessionary trough.
B. Expansion, business peak, recessionary trough, contraction.
C. Depression, expansion, business peak, contraction.
参考答案：A
解析：
If the economy is just beginning to come out of a recession, a period of expansion is beginning. In a typical business cycle, this will be followed by a business peak, and a period of contraction, leading to the next recessionary trough. This would complete one cycle from the time of the last recession. C is not appropriate since the question says that the economy is coming out of a recession. This suggests that the economy is getting better, not worse.
