Question: Which lasted longer, World War Two or the Korean War? Passage 1:He was born in Saint-François on the Île d'Orléans, Canada East, the son of Louis Asselin and Marie Laperrière, and was educated at the Séminaire de Québec and the Université Laval. Asselin was called to the Quebec bar in 1870 and set up practice in Rimouski. In 1876, he married Théotiste-Malvina-Louise Derome. He served as crown prosecutor for Rimouski district in 1880 and 1881. Asselin ran unsuccessfully for a seat in the Quebec assembly in 1880, losing to Joseph Parent, and then defeated Parent in the 1881 general election. He was defeated by Édouard-Onésiphore Martin when he ran for reelection in 1886, also losing a by-election in 1889 and then elections for the Quebec assembly in Matane in 1890 and in Rimouski in 1908. Asselin was mayor of Rimouski from 1885 to 1887, was school commissioner from 1895 to 1898 and from 1903 to 1915 and was sheriff for Rimouski from 1895 to 1898. He was a founder and director of the newspaper Progrès du Golfe. Asselin was president of the Rimouski Saint-Jean-Baptiste Society. In 1914, he was named a repatriation officer at Biddeford, Maine for the Canadian government, charged with encouraging former Quebec residents who had emigrated to the United States to return to Quebec. He died there seven years later at the age of 71.
 Passage 2: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.
 Passage 3:The widespread use of the swan as a badge largely derives from the legend of the Swan Knight, today most familiar from Richard Wagner's opera Lohengrin. A group of Old French chansons de geste called the Crusade cycle had associated the legend with the ancestors of Godfrey of Bouillon (d. 1100), the hero of the First Crusade. Although Godfrey had no legitimate issue, his family had many descendants among the aristocracy of Europe, many of whom made use of the swan in their heraldry or as a para-heraldic emblem. In England these included the important de Bohun family, which used the so-called Bohun swan as its heraldic badge; after the marriage in 1380 of Mary de Bohun (d. 1394) to the future King Henry IV of England, the swan became adopted by the House of Lancaster, who continued to use it for over a century. The swan with the crown and chain is especially associated with Lancastrian use; it echoes the crown and chain of Richard II's white hart, which he began to use as a livery badge from 1390. As well as several of his own white hart badges, Richard's treasure roll of 1397 also includes a swan badge with a gold chain, perhaps presented by one of his enemies mentioned above: "Item, a gold swan enamelled white with a little gold chain hanging around the neck, weighing 2 oz., value, 46s. 8d". He declared to Parliament that he had exchanged liveries with his uncles as a sign of amity at various moments of reconciliation.
