解释：
此处的Price是理解为存货出售价格还是COGS呢
NO.PZ2018062018000039问题如下The LIFO reserve will not cline if:A.prices are rising.B.prices are falling.C.a firm is liquiting its inventory.A is correct. The LIFO reserve will increase when prices are rising aninventory quantities are stable or increasing. If a firm is liquiting its inventory, or if prices are falling, the LIFO reserve will cline.如题，画个向下的箭头，代表价格持续下跌，这样lifo reserve不是也会增加吗

The LIFO reserve will increase when prices are rising aninventory quantities are stable or increasing. If a firm is liquiting its inventory, or if prices are falling, the LIFO reserve will cline. 不是说LIFO Reserve是持续上升的才对吗？正常来说物价就是上涨的那为啥LIFO Reserve还能下降

The LIFO reserve will increase when prices are rising aninventory quantities are stable or increasing. If a firm is liquiting its inventory, or if prices are falling, the LIFO reserve will cline.当原材料价格上升时，如果企业进行LIFO liquition，那么LIFO reserve就会下降呀，为什么题目说不会下降？
NO.PZ2018062018000039 prices are falling. a firm is liquiting its inventory. A is correct. The LIFO reserve will increase when prices are rising aninventory quantities are stable or increasing. If a firm is liquiting its inventory, or if prices are falling, the LIFO reserve will cline.答案可以当结论记下来吗
请问，当原材料价格下降的时候，企业没有动力去使用原来便宜的存货，可以直接在市场购买更便宜的原材料。此时，LIFO reserve应该不会下降的。所以B正确啊。为什么是A呢。
