Answer:
The Civil Rights Act of 1968
Step-by-step explanation:
It can't be Brown v . Board of Education of Topeka or Title IX of the Education Amendments as these both are specifically about racial segregation in schools.
Civil Rights Act of 1964, prohibiting discrimination based on race, color, religion, sex, and national origin by federal and state governments as well as some public places. Civil Rights Act of 1968, prohibiting discrimination in sale, rental, and financing of housing based on race, creed, and national origin.
1968 had expressly to do with housing; 1964 did not. The 1968 act prohibited discrimination based on race, religion, and national origin, was expanded in 1974 to include gender, and was expanded again in 1988 to protect people with disabilities and families with children.
