Question

during which decade did the us pursue a policy of isolationism?
1910s
1920s
1930s
1940s

Explanation:

After World War I, the U.S. sought to avoid European conflicts. In the 1920s, the government passed isolationist policies like immigration restrictions and refused to join the League of Nations, prioritizing domestic affairs over global involvement. The 1930s saw some shifts with early WWII tensions, the 1910s included U.S. entry into WWI, and the 1940s involved full U.S. participation in WWII, so these decades do not fit the peak isolationist policy pursuit.

Answer:

B. 1920s
