问题如下：
Which duration measure should be matched when implementing Strategy 2?
选项：
A.Key rate
B.Modified
C.Macaulay
解释：
C is correct.
An investor having an investment horizon equal to the bond’s Macaulay duration is effectively protected, or immunized, from the first change in interest rates, because price and coupon reinvestment effects offset for either higher or lower rates.
请问continuously matching duration该怎么理解？我可能是被这个单词误导了，我一直以为是“连续不断地”或者“持续地” match duration，那这样就包含了利率非平行移动的情况，所以就选了A。
