I want to know the answer to the following question:
What did David Lloyd George's coalition government reject in 1921?
All the background I'm provided with is that "During the 1920s and 1930s, British civil servants and politicians, looking back at the performance of the state during World War I, concluded that there was a need for greater co-ordination between the three Services that made up the armed forces of the United Kingdom—the British Army, the Royal Navy, and the Royal Air Force.". Is that enough to answer the question?
Answer: no
