Which amendment, ratified in 1920, guaranteed women's suffrage?

• A. 18th
• B. 20th
• C. 21st
• D. 19th

Answer: (C)

The main point is to know which change to the Constitution guaranteed women the right to vote. In 1920, an amendment was ratified that states the right to vote cannot be denied or abridged on account of sex. This amendment is what protects women’s suffrage. Because it specifically enshrined voting rights regardless of gender and it was ratified in 1920, it is the one that guarantees women's right to vote. The other amendments mentioned have different purposes—one established Prohibition, another set the dates for when federal offices begin, and the last repealed Prohibition—so they don’t address voting rights for women.
