Final answer:
Assimilation is the process by which individuals or groups adopt the culture of the dominant group, abandoning their original cultural identity.
Step-by-step explanation:
An acculturation strategy in which the person adopts the new culture and rejects the old culture is known as Assimilation. When individuals or groups assimilate, they give up their own cultural identity and take on the characteristics of the dominant culture. This process can involve changes in language, dress, values, religion, and social practices. Assimilation is often seen in the context of immigration, where immigrants adapt to their host country's culture. While assimilation can lead to greater integration within society, it can also result in the loss of unique cultural traits and heritage.
