Which of the following was not a result of the growing fear that was part of nationalism in 1920s america?

I believe the answer is: The Sacco and Vanzetti Trial and sentencing

In 1921,  Sacco and Vanzetti were sentenced to death by the court for their crime. Many people said that the sentencing was driven by anti-immigrant bias. But the court had a really strong evidence that both of them were committing first-degree murder.  So it is unlikely that the decision was influenced by nationalism.
