Not until did man accept that fact that all living things must die.
A. did many years pass
B. many years past
C. many years had passed
D. many years have passed

@@A. did many years pass@@B. many years past@@(答案)C. many years had passed@@D. many years have passed
解析：
从后面的did man accept可以看出not until后面连接的是一个时间状语从句，不能用倒装句；同时也应该判断出，many years的流逝是发生在accept之前的，所以这个时间状语从句应该用过去完成时态。句子的意思是“直到很多年过去，人们才接受这么个事实：一切生物都是要死亡的”
