Answer:
The correct answer is B.
Explanation:
During the migratory waves of the late 1800s and early 1900s to the United States, millions of citizens from southern and eastern European nations such as Italy, Russia or the Balkans began to arrive in the country.
These people, although they shared in principle the Caucasian condition of the Anglo-Saxon inhabitants of the nation, had with these many cultural differences, especially with regard to religion and social traditions. Thus, they were either Catholic or Orthodox immigrants, coming from more traditionalist societies, who arrived in many cases mired in poverty, with the objective of making economic progress motivated by the American Dream.
Now, these people were seen by the most conservative Americans as a threat, not only because they considered that they took away job opportunities from many Americans, but also because they jeopardized the Protestant culture of the nation.
