I want to know the answer to the following question:
During what two decades were the Parliament House, Treasury Building, Victoria Barracks, State Library, and General Post Office commenced?
All the background I'm provided with is that "With the wealth brought on by the gold rush following closely on the heels of the establishment of Victoria as a separate colony and the subsequent need for public buildings, a program of grand civic construction soon began.". Is that enough to answer the question?
Answer: no
