1.It reaffirmed the rights granted in the Thirteenth, Fourteenth, and Fifteenth Amendments.
2.Women were given the right to vote by the passage of the act.
3.The right to vote was given to citizens who were 18 years old.

Answer 1

The civil rights act was considered an expansion of rights in U.S political thought primarily because it reaffirmed the rights granted in the Thirteenth, Fourteenth, and Fifteenth Amendments. These amendments had been enacted in the aftermath of the Civil War, and the civil rights act reinforced and protected the rights provided by these amendments. The act aimed to prohibit discrimination based on race, color, religion, sex, or national origin, ensuring equal treatment and protection under the law for all citizens. While the other options mentioned in the question are important historical developments, they are not directly related to the civil rights act and its specific impact on expanding rights in U.S political thought.
