The split-household family was common and crossed national borders among which group?

• A. Mexican Americans
• B. Chinese Americans
• C. Mormons
• D. African Americans

Answer: (B)

The main idea here is transnational or split-household families—families where members live in two or more countries due to migration. Chinese Americans are the best example because, historically, many Chinese men came to the United States for work in the late 19th and early 20th centuries and were often prevented from bringing their families because of restrictive immigration laws. This led to long periods of separation across borders, with families staying connected from afar and eventual attempts at reunion later on. While other groups have cross-border ties, the pattern of widespread, long-term split households across the U.S.–China divide is most strongly documented for Chinese American families, making this the most fitting answer.
