Question

Because these are class actions, because of the wide applicability of this decision, and because of the great variety of local conditions, the formulation of decrees in these cases presents problems of considerable complexity.

Why does the Supreme Court describe these considerations?
to explain the historical context in which segregation was endorsed
to illustrate the different interpretations of the law throughout the nation
to compare the quality of education delivered throughout the years of segregation
to emphasize the challenges inherent in determining a ruling for a varied nation

Answer 1
