Which of the following applies to the process of integrating different cultures into one?

The process of integrating different cultures into one is best described as cultural assimilation, which occurs when individuals or groups from one culture adopt the customs, values, and beliefs of another culture, leading to a blending or merging of cultural identities. This often results in the minority group gradually adopting the characteristics of the dominant culture, sometimes to the point of losing distinct cultural traits.

Cultural integration, while it does refer to the combining of different cultural practices, usually emphasizes cooperation and interaction without necessarily implying that one culture absorbs another. Cultural harmony suggests a peaceful coexistence of different cultures, highlighting respect and mutual support rather than integration. Cultural adaptation refers to the adjustments individuals make when they come into contact with a new culture but does not fully encompass the idea of merging one culture into another.

In summary, cultural assimilation focuses specifically on the process where one culture becomes dominant, effectively integrating or absorbing other cultures into it, which aligns accurately with the question's context of integrating distinct cultures into a unified whole.
