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.

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.

i believe it is capitalists.
