I want to know the answer to the following question:
How many subordinate divisions did the National Military Establishment contain?
All the background I'm provided with is that "The act created the National Military Establishment (renamed Department of Defense in 1949), which was composed of three subordinate Military Departments, namely the Department of the Army, the Department of the Navy, and the newly created Department of the Air Force.". Is that enough to answer the question?
Answer: yes
