问题如下：
The inventory/sales ratio is most likely to be rising:
选项：
A.as a contraction unfolds.
B.partially into a recovery.
C.near the top of an economic cycle.
解释：
C is correct.
Near the top of a cycle, sales begin to slow before production is cut, leading to an increase in inventories relative to sales.
考点：Resource Use Through The Business Cycle
解析：经济位于顶点的时候，销售快要卖不动了，存货也逐渐开始挤压，所以 inventory/sales 最有可能将要上升。C选项正确。
A选项的条件下inventory/sales已经上升了
B选项的条件下inventory/sales开始出现下降
as a contraction unfolds 这句话怎么理解
不是在通货紧缩阶段 sells 减少 所以inventory/sales 增加嘛
