Final answer:
Women in the U.S took up various roles upon the nation's entry in World War I. They notably served in the Women's Land Army, performed industrial work symbolized by the figure 'Rosie the Riveter', worked in medical fields, primarily as nurses, and some also served in the military.
Step-by-step explanation:
Immediately after the U.S entered World War I, women were enlisted on a large scale into various job titles, including female service members, nurses, and industrial workers. The most notable job title that saw a significant increase in female enlistment was the Women's Land Army. Thousands of women, also referred to as Farmerettes, stepped up to run farms and undertake other agricultural tasks as men left for armed forces.
Another significant sector where women contributed was the industrial field, symbolized by the icon 'Rosie the Riveter'. They worked behind desks in offices and industries, and their number in the banking sector had doubled towards the end of the war. In the medical field, women primarily served as nurses, with some also worked as ambulance drivers and in x-ray units.
Approximately 350,000 women served in the U.S military in varying capacities like nurses, drivers, airplane repairers, and clerical workers. A notable group among them, known as 'Hello Girls', served as telephone operators in France. Other women served in humanitarian organizations such as the Red Cross and YMCA.
