Answer :
The correct answers are A) cultural classes and B) newspapers.
Immigrants in the early 20th century used cultural classes and newspapers to help them learn the culture of North America.
One of the most difficult thing for an immigrant is the integration into the new society. This was the case for the immigrants that arrived in the United States. Cultural classes helped them to understand the way American people thought and behave. This allowed immigrants to get an idea of the belief systems of the U.S. citizens. And through the newspapers, immigrants learned about the situation and context of what was happening in those moments, which helped them to be familiar with the political, economic, and social issues affecting the American people.
