Answer:
Cultural Assimilation
Step-by-step explanation:
Cultural assimilation occurs when a minority that lives in a different area gives up their own culture to adopt traits and beliefs from the dominant culture. In this case, Heather is giving up both her citizenship and religion to accept the main culture in Egypt.
Many times cultural assimilation has a negative connotation because it has a history of diminishing minority cultures. This is not happening in Heather's case as she is converting from a large religious group. Additionally, it is her choice to convert. It is common for minority immigrants to have to assimilate in order to survive in a new, foreign environment.
