The days ________ black people in the country could not trave without a passbook are gone for ever.
A. in which B. on which

Which of the answers are suitable? Why?

Thanks

[Eric Thompson]

Dear jasonlulu_2000: The answer is 'in which'. Why? Because we use the preposition 'in' in such phrases as 'in the old days', 'in the year 2000', 'in the past'. So, in describing time, use 'in', except 'on Saturday' and 'at 5 o'clock'. ok? -- Eric
