Think about what you know about nativism and exclusion. Remember how these problems made it very difficult for Chinese and Japanese people to move to the United States. What most likely happened by the 1920s?

Nativism led to laws and policies that restricted immigration from China and Japan. As those barriers made it much harder for people from these countries to enter the United States, their immigration rates most likely declined by the 1920s. The correct choice is “Immigration rates for these groups declined.”
