Final answer:
Not an example of assimilation is an immigrant being denied college access unless they change their name, as assimilation involves voluntary cultural integration, not forced conformity.
Step-by-step explanation:
Assimilation is a process where an individual or a minority group loses its original identity by adopting the characteristics of a dominant or host culture. The question asks which scenario is not an example of assimilation. The correct answer is: an immigrant from Italy is denied access to the U.S college of their choice unless they change their name to an English name. This situation represents a form of forced conformity and discrimination but is not an assimilation process, where the integration is a voluntary and complete integration into the dominant culture's system.
