2道定语从句的题的比较~~

1.you may call on me from one to five o'clock,during ____ always at home.
A.the time B.what time C.which time D.which
为什么不选C而选D?
2.而为什么这道题就只能选by which time了?
In the office I never seem to have time until after 5:30 p.m. ___ many people have gone home.
为什么不用by which了?

原因在于第一题的时间是时间段,which代指前面的from one to five o'clock.而第二题.by which time中,which time指的不是after 5:30而是就5:30这个时间点,就在这个确切的时间点(by到这个时间点)和它之后都有空.我个人觉得相当与when 和 what time 的区别.只是猜测!
