Answer:
The answer is letter C): the constant threat of strikes by the men and women who worked in the factories.
Step-by-step explanation:
When the United States entered into World War I, there was a surge in labor strikes: within 6 months, American workers went on strike over 3,000 times, and over 10,000 workers participated in at least 67 of the strikes. These levels of unprecedented and incessant strikes prompted the federal government to form and establish a close relationship between its ruling Democratic Party and the AFL leader, Samuel Gompers, who pledged that there would be no strikes during the war. Samuel Gompers, who was appointed to the Advisory Council on Labor (Council on National Defense), ensured that union representatives worked together with government agencies to prevent strikes.
