Final answer:
Geraldine Ferraro became the first woman to be nominated as a major-party vice presidential candidate in 1984, running with Walter Mondale on the Democratic ticket.
Step-by-step explanation:
The first woman to be nominated as a major-party vice presidential candidate in 1984 was Geraldine Ferraro. She was on the Democratic ticket with presidential candidate Walter Mondale. Although they did not win the election, her nomination was a historic moment for women in politics, demonstrating progress towards gender equality in American political life. This event paved the way for future female politicians, including Kamala Harris, who later became the first woman vice president of the United States as well as the first person of Black and South Asian descent to hold the office.
