Input: Question: Which lasted longer, World War Two or the Korean War? Passage:Ferrell's biography follows the course of Truman's life from his birth in 1884 in Lamar, Missouri to his 1972 death and burial at the Truman Library in Independence. The first five chapters examine his service as a captain in World War I, his pre-politics careers in banking, farming, and a failed run as a haberdasher which ended in bankruptcy, and marriage to Bess Truman in 1919. Chapters six to eight look at his early political career, launched by Kansas City boss Tom Pendergast, beginning with his election as a county judge in 1922, then senator in 1934, and in 1944, vice president to Franklin Roosevelt, in a behind-the-scenes compromise Ferrell calls "the most extraordinary political arrangement of the present century"—Democratic Party leaders could see that the extremely ill Roosevelt was unlikely to survive his fourth term in office, and had to convince him to drop then-VP Henry Wallace in favor of Truman, who was felt to be a more "reliable" man. Truman ascended to the presidency upon Roosevelt's death in 1945, and this period in Truman's life is covered in chapters nine to 17—the majority of the book—including Truman's decision to detonate atomic weapons on Hiroshima and Nagasaki to force an end to World War Two, his unexpectedly successful reelection in 1948, his civil-rights initiatives, and his administration's handling of foreign-policy issues, most prominently the Korean War.
