The correct answer to this open question is the following.
Although there are no options attached we can say the following.
The Chinese Exclusion Act the Gentleman Agreement, and the National Origin Act, all show that at times the United States has favored limiting immigration at different times in the nation’s history, rejecting the entrance of foreign people into the United States territory.
For instance, there was the case of the Workingmen's Party that showed prejudice against Chinese immigrants because they feared competition for jobs. As a result of this, people on the West Coast persuaded Congress to pass the Chinese Exclusion Act, a law that ended most Chinese immigration to the United States.
Nativism in the United States had a big impact on immigration. White people were angry because they said immigrants such as the Chinese took jobs that belonged to them.
