Which action is an example of nativism in the 1920s?

In the 1920s, the Ku Klux Klan promoted laws restricting immigration and promoted eugenics in the United States. This is an example of nativism in the 1920s because it promotes policies that favor native-born Americans over immigrants, and because it promotes the selective breeding of humans in order to "improve" the genetic makeup of the population.
