问题如下：
Zimt AG wrote down the value of its inventory in 2007 and reversed the write-down in 2008. Compared to the ratios that would have been calculated if the write-down had never occurred, Zimt’s reported 2007:
选项：
A. current ratio was too high.
B. gross margin was too high.
C. inventory turnover was too high.
解释：
C is correct.
The write-down reduced the value of inventory and increased cost of sales in 2007. The higher numerator and lower denominator mean that the inventory turnover ratio as reported was too high. Gross margin and the current ratio were both too low.
我没太明白题目意思，难道不是如果没有减值，会怎么样嘛？
