问题如下：
1. For Concept 1, the statement is correct regarding the effects on:
选项：
A.the real tax savings from depreciation, but incorrect regarding the real after-tax interest expense.
B.both the real tax savings from depreciation and the real after-tax interest expense.
C.neither the real tax savings from depreciation nor the real after-tax interest expense.
解释：
C is correct.
The value of the depreciation tax savings is increased, and the value of the real after-tax interest expense is also increased. Due to the lower inflation, the value has increased (essentially discounting at a lower rate).
请问老师，这道题的意思是，tax saving of depreciation还有after tax interest expense绝对值是不变的，但是由于inflation低于预期，这两者的实际价值是增加的，对吗？
