Answer: 4. Regents of the University of California v. Bakke
Explanation:
In June 1978, the Supreme Court declared that affirmative action was legal insofar as racial quotas were not used. The case was brought by a white California man, Allan Bakke who said he had suffered reverse racism as he had higher scores than minority group members but was refused admission because of a University rule that reserved 16% of admission slots for minority groups. The Supreme Court ordered the University to admit Bakkie as using quotas was unconstitutional but also held that race can be used as a valid factor in admissions decisions.
This showed that affirmative action was legal but subject to scrutiny.
We know this thanks to archaeologists who excavated many places and discovered that many early civilizations gathered around large rivers where they could develop agriculture. This was seen in places such as Mesopotamia, India, China, Egypt, etc.
