Final answer:
Nativism in the United States in the 1920s can be most accurately represented by the passing of the Immigration Act of 1924, which limited the number of immigrants from non-Western Hemisphere countries.
Step-by-step explanation:
The best example of nativism in America during the 1920s among the options presented is 'Congress passed a law in 1924 that strictly limited immigration'. Known as the Immigration Act of 1924 or the Johnson-Reed Act, it established quotas that essentially limited immigration from countries outside the Western Hemisphere, particularly those of Southern and Eastern Europe and Asia. The law reflected the nativist and xenophobic sentiments prevalent during this era. The rest of the options either happen outside the timeline or are not corroborated by factual historical events.
