I want to know the answer to the following question:
During what years did the five Departments of State do the work of the modern Ministry of Defence?
All the background I'm provided with is that "From 1946 to 1964 five Departments of State did the work of the modern Ministry of Defence: the Admiralty, the War Office, the Air Ministry, the Ministry of Aviation, and an earlier form of the Ministry of Defence.". Is that enough to answer the question?
