Which of these was NOT a problem during the interwar period?
Ccc

the interwar period was the period between the end of the First World War on 11 November 1918 and the beginning of the Second World War on 1 September 1939.

Explanation:

the period represented an era of significant changes worldwide. Petroleum-based energy production and associated mechanisation expanded dramatically leading to the Roaring Twenties, a period of economic prosperity and growth for the middle class in North America, Europe, Asia and many other parts of the world. Automobiles, electric lighting, radio broadcasts and more became common among populations in the developed world.
