Yes you can. The Administrative Center building isn't unique like the Summer Palace was (which has been removed by the way, forgot to mention that), so it works like Cathedrals: you can build one for every X prereq buildings.
Thanks. I agree about the bias, but everything helps.
The graphics help and don't help. Having female graphics will be very useful in a while, but I still also need male graphics, and the icon should reflect that most examples will be male imo.
