Final answer:
The correct option illustrating a cause and effect relationship is the Red Scare leading to the demand for limits on immigration in the 1920s, reflecting how fears of radicalism influenced immigration policy.
Step-by-step explanation:
Among the given choices, the option that illustrates an accurate cause and effect relationship is Red Scare - demand for limits on immigration. The Red Scare refers to the period of intense fear of communism and other politically radical ideas in the United States that followed the Russian Revolution and the end of World War I. It led to widespread suspicion of subversive activities and a fear of widespread infiltration of communists in American society. This pervasive fear contributed directly to the demand for stricter immigration laws to limit the influx of foreigners, who were often associated with radical political movements at the time.The Red Scare significantly impacted the political climate of the United States in the 1920s. Americans were deeply concerned about communism and anarchy, which were associated with recent immigrants, especially those from Eastern Europe and Russia. As a result, there was strong support for legislation that would restrict immigration and reduce the threat of radicalism. The Immigration Act of 1924, also known as the National Origins Act, effectively reduced immigration by establishing quotas that discriminated against individuals from countries deemed less desirable. The fear induced by the Red Scare therefore had a direct and tangible effect on immigration policy.In conclusion, the cause and effect relationship between the Red Scare and the demand for limits on immigration in the 1920s is a clear example of how national security concerns can influence domestic policy, specifically in regulating the composition and number of people allowed to enter the United States.
