Input: Question: What is the height of the peak of the mountain where the Aspen Mountain ski resort was established? Passage 1:The Company was founded in 1946 by Friedl Pfeifer, an Austrian ski instructor and racing champion, Walter Paepcke, a successful Chicago industrialist, Judge William E. Doyle, James J. Johnston, and H. F. Klock. Paepcke also founded cultural institutions in the city, such as the Aspen Institute and the Aspen Music Festival. The Aspen Skiing Company established the Aspen Mountain ski resort on Aspen Mountain above the town of Aspen, Colorado. The first chair lift, Lift-1, opened on December 14, 1946, and was the world's longest chairlift at the time. In 1950, the company hosted the FIS World Alpine Championships, the first international skiing competition in the United States. In the following decades, the company opened Buttermilk in 1958 and the Snowmass (originally the Snowmass-at-Aspen Ski Area) in 1967. In 1993 the company assumed ownership and operation of Aspen Highlands, which was founded in 1958 by Colorado Ski Hall of Famer: Whip Jones. Previously, Jones successfully sued Aspen Skiing before the Supreme Court for antitrust violations in Aspen Skiing Co. v. Aspen Highlands Skiing Corp.
 Passage 2:There were 45 entrants for the race, but only the quickest 30 drivers during the elimination trials would qualify for the race. The first day of trials was completed on the Monday before the race, 25 May. Caleb Bragg set the fastest official time on the first day, recording 1:36.8, though it was reckoned that Howdy Wilcox went quicker, but his time was not officially recorded. Ralph DePalma, a crowd favourite, struggled in his Mercedes and could only manage a quickest time of 1:47.4, slower than the 1:45 that it was predicted drivers would have to beat in order to qualify. Only fifteen of the drivers ran on the first day, and they continued with two session on the Tuesday. On the second day, three drivers set record times around the Speedway: first the 1912 winner, Joe Dawson, set an unofficial lap time of 1:34.8. Later in the day Teddy Tetzlaff completed a lap in 1:33.4, while Jules Goux finished the day as the fastest driver, with a time of 1:31.7. Tetzlaff's lap was completed in a Maxwell which was fuelled with a 50:50 mix of gasoline and kerosene; the other Maxwell, driven by Billy Carlson, set a time of 1:36.6 fuelled by a combination of kerosene and lucubrating oil, with no gasoline. Ray Harroun, who had won the inaugural Indianapolis 500 in 1911, designed the Maxwell car, and was given $10,000 () by the company's president as a reward for the cars qualifying with sub-1:37 times.
 Passage 3:Newton's first PDC major was the 2003 UK Open where he lost 8–6 to Mark Thomson in the last 32. He was beaten in the semi-finals of the Eastbourne Open in 2003 and 2004 and reached the first final of his career at the Golden Harvest North American Cup, but lost 4–0 to John Part. Newton qualified for the 2004 Las Vegas Desert Classic and was beaten 2–1 by Wayne Mardle in the first round. His World Championship debut came in 2005 when he lost 3–0 to Gerry Convery in the second round. His first semi-final in a major event was at the 2005 Las Vegas Desert Classic where he knocked out George Walls, Mark Walsh and Ray Carver, before losing 4–0 to Phil Taylor. Newton suffered a broken collarbone by slipping in the shower shortly after the event which kept him out of action for three months but returned to play in his first World Grand Prix, losing 3–0 in the second round to Colin Lloyd.
