问题如下：
Jacques is preparing the valuation for PZ Inc.. Based on the company’s financial statements, Jacques noticed about 5 percent of PZ Inc.’s growth in FCFE has come from decreases in inventory. Shall we consider the decreases in inventory a sustainable source of long-term growth in FCFE?
选项：
A.Yes
B.No, decreases in inventory are a use rather than a source of cash
C.No, inventory reduction has a limit, particularly for a growing firm.
解释：
C is correct.
考点：FCFE
解析：C是正确的。存货最多降到零，此方法是不可持续的。
题干问减少存货能否提供可持续现金流？答案是否定的，因为存货是有下限的（最低减少到0，所以不能提供可持续性现金流），并不是因为它是一种用途或来源，所以B不对。
还是有点儿疑问，今年存货减少了，明年随着不断新的生产活动，存货还会增加啊，没有谁家的企业是存货一直减少的
