Which young adult is more likely to live on her own? mae ling, a first-generation asian american aaliyah, an african-american college student julia, a well-off european american marisa, an unmarried latina?

The right answer is "a well-off European American Marisa". In the Caucasian culture, it is common for young adults to leave their parents' homes and live alone. Many are helped economically by their parents until they finish their university studies or when they stabilize in a job. In other cultures, such as Latin or Asiatic, it is common for children to leave home when they get married, or until they have the economic stability to become independent.

I hope my answer can help you.
