Answer:
de facto segregation
Step-by-step explanation:
Clearly, the word segregation leaves no doubt as to its more general meaning, when we search the dictionary for the word segregation means separation; division in order to avoid contact; isolation. In the case shown in the question above we can see that there is a case of de facto segregation, since African American children have been separated from white-skinned children in order to avoid contact between these two "races" of children.
