Answer: C
Explanation: The behavior of Irish immigrants attempting to learn the traits and behaviors of the dominant white culture represents assimilation. Assimilation is the process by which individuals or groups adopt the norms and values of the dominant culture in order to fit in and be accepted. In this case, the Irish immigrants were trying to assimilate into white American culture in order to improve their social standing and opportunities in the United States. This is different from pluralism, where different cultural groups coexist without necessarily adopting the dominant culture, and segregation, where cultural groups are forcibly separated based on race or ethnicity. Amalgamation, also known as racial mixing, refers to the mixing of different racial or ethnic groups through intermarriage.
