Could I understand that like this?
Nevertheless, such a generalisation does not take us far towards an understanding of why the revolution broke out when it did, and why it took the remarkable road it did.
---
why the revolution broke out when it(the revolution) did(broke out), and why it(the revolution) took the remarkable road [which] it(the revolution) did(took the remarkable road)
Could I understand that like this?
I really wonder why the last phrase(it did) of this sentence was used?
Is it for emphasis?
Please help me!
Thanks!^^
