Answer:The interwar period in the United States, and in the rest of the world, is a most interesting era. The decade of the 1930s marks the most severe depression in our history and ushered in sweeping changes in the role of government. Economists and historians have rightly given much attention to that decade. However, with all of this concern about the growing and developing role of government in economic activity in the 1930s, the decade of the 1920s often tends to get overlooked. This is unfortunate because the 1920s are a period of vigorous, vital economic growth. It marks the first truly modern decade and dramatic economic developments are found in those years. There is a rapid adoption of the automobile to the detriment of passenger rail travel. Though suburbs had been growing since the late nineteenth century their growth had been tied to rail or trolley access and this was limited to the largest cities. The flexibility of car access changed this and the growth of suburbs began to accelerate. The demands of trucks and cars led to a rapid growth in the construction of all-weather surfaced roads to facilitate their movement. The rapidly expanding electric utility networks led to new consumer appliances and new types of lighting and heating for homes and businesses. The introduction of the radio, radio stations, and commercial radio networks began to break up rural isolation, as did the expansion of local and long-distance telephone communications. Recreational activities such as traveling, going to movies, and professional sports became major businesses. The period saw major innovations in business organization and manufacturing technology. The Federal Reserve System first tested its powers and the United States moved to a dominant position in international trade and global business. These things make the 1920s a period of considerable importance independent of what happened in the 1930s.
Plant domestication: Cereals such as emmer wheat, einkorn wheat and barley were among the first crops domesticated by Neolithic farming communities in the Fertile Crescent. These early farmers also domesticated lentils, chickpeas, peas and flax.
