Question: What skiier placed first in the 2007 giant slalom event where Karlsen finished sixth? Passage 1:In the 10th century, Abd al-Rahman al-Sufi (Azophi) carried out observations on the stars and described their positions, magnitudes, brightness, and colour and drawings for each constellation in his Book of Fixed Stars. He also gave the first descriptions and pictures of "A Little Cloud" now known as the Andromeda Galaxy. He mentions it as lying before the mouth of a Big Fish, an Arabic constellation. This "cloud" was apparently commonly known to the Isfahan astronomers, very probably before 905 AD. The first recorded mention of the Large Magellanic Cloud was also given by al-Sufi. In 1006, Ali ibn Ridwan observed SN 1006, the brightest supernova in recorded history, and left a detailed description of the temporary star.
 Passage 2:In 1923, Calhern left the movies, deciding to devote his career entirely to the stage, but he would later return to the screen after the advent of sound pictures. In films, He was primarily cast as a character actor, while he continued to play leading roles on the stage. He reached his peak in the early 1950s as a Metro-Goldwyn-Mayer contract player. Among Calhern's many memorable screen portrayals were Ambassador Trentino in the Marx Brothers classic Duck Soup (1933) and three diverse roles that he appeared in at MGM in 1950: a singing role as Buffalo Bill in the film version of the musical Annie Get Your Gun, as a double-crossing lawyer and sugar-daddy to Marilyn Monroe in John Huston's film noir classic The Asphalt Jungle, and his Oscar-nominated performance as Oliver Wendell Holmes in The Magnificent Yankee (re-creating his role from the Broadway stage). He was also praised for his portrayal of the title role in the John Houseman production of Julius Caesar (adapted from the Shakespeare play) in 1953, directed by Joseph L. Mankiewicz. Calhern also played the role of the devious George Caswell, the manipulative board member of Tredway Corporation in the 1954 production of Executive Suite.
 Passage 3:Truls Ove Karlsen (born 25 April 1975 in Oslo) is a retired Norwegian alpine skier. He made his Alpine Skiing World Cup debut in Sölden in 2001. He made a total of 143 World Cup starts, finishing third in a slalom in Sestriere in December 2002 and scoring his only World Cup win in a slalom in Kranjska Gora in February 2004, leading home team-mate Tom Stiansen in a Norwegian one-two ahead of Austrian Mario Matt. His best World Cup seasons were 2003 and 2004, where he finished eighth in the slalom standings. His best results at the Alpine Skiing World Championships were achieved at the 2007 Championships in Åre, where he finished sixth in the giant slalom and seventh in the slalom. He represented Norway at the 2010 Winter Olympics. Karlsen announced his retirement from competition in February 2013. Since then he has worked as a personal trainer. He graduated from the Norwegian University of Science and Technology with a bachelor's degree in History and Psychology in 2004, and started studies for a master's degree in law at the University of Oslo in 2013.
