Which former U.S. president authored 'The Audacity of Hope'?

• A. Bill Clinton
• B. George W. Bush
• C. Ronald Reagan
• D. Barack Obama

Answer: (D)

Identifying who wrote a famous presidential book. The Audacity of Hope is a work by Barack Obama, published in 2006 when he was serving as a U.S. senator and emerging on the national stage. The book presents his ideas on unity, opportunity, and public service, and the phrase itself became closely associated with his vision and later political campaigns. The other presidents listed did publish memoirs, but under different titles—so they don’t match this particular book. In short, Barack Obama is the author of The Audacity of Hope.
