In this question, you did not include the stories that you are meant to be studying. Therefore, we cannot provide information on that subject. However, we can still discuss how the United States changed and developed between the 1920s and the 1940s.
During this time period, the country experienced an enormous amount of change. The 1920s was a period of abundance and economic success. Many people consider it a time of great improvement, as the economic situation of the country improved in a very significant way. However, this all came to a stop in 1929, as the New York Stock Exchange crashed. Many lost their money and their jobs, and this led to what is known as the Great Depression. The Great Depression, along with the Dust Bowl, pushed many people to poverty. However, the economic situation finally improved again in the late 1930s, as well as during and after the war. First, this improvement was the result of the New Deal, an economic plan implemented by Franklin D. Roosevelt. Second, the economy benefited from the industry that was developed to address the needs of the war.
