问题如下：
Assuming a periodic inventory system, technology company TBC is facing decreasing prices. Which of the following methods will make its reported profits look higher?
选项：
A. Special identification method.
B. LIFO method.
C. FIFO method.
解释：
B is correct. When the price is decreasing, the newly-purchased inventory costs less than before, adopting the LIFO method will lead to less cost of sales, and then lead to higher profit.
商品价格下降，为什么会代表inventory cost降低？我的理解是商品价格下降，利润少了，相对inventory cost是上升的。
