Which describes one reason that the U.S. Constitution was amended in the twentieth century?

One reason the U.S. Constitution was amended in the twentieth century was to address societal changes and evolving democratic values. For example, the 19th Amendment, ratified in 1920, granted women the right to vote, reflecting the growing movement for gender equality. Similarly, the 26th Amendment, ratified in 1971, lowered the voting age to 18, acknowledging the role of younger citizens in civic engagement, especially during the Vietnam War era. These amendments illustrate the Constitution's adaptability to reflect the changing needs and rights of American citizens.
