Answer:
Blank 1; Veto. Blank 2; Transport
Explanation:
I'm not sure that Veto fits the blank because it could be that or petition, neither really fit but I've narrowed it down to those two. Blank two I know and I'm confident that it's transport.
I would say 30,000 cause all the next developments were from the 1860's forward and that is when huge growth happened, after 1860.
This is the answer I hope I could help you!:)
