Answer:
When Christoph changes her daughter's name so she won't face any discrimination when she grows up, marries and lives her life is an example of Passing.
Explanation:
First of all to understand the answer we need to remember the concept of "passing".
Passing is the act to adapt to a new group to assure survival. The subject that performs "Passing" knows that her or his authentic self could find different problems for being who she or he is. So he or she claims, considers, and regards herself or himself to a different and new group to avoid the problems his or her former group characteristics could provide him or her. In this case, renaming his daughter was a perfect example.
