Input: Consider Input: Question: What is the height of the peak of the mountain where the Aspen Mountain ski resort was established? Passage: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.

Input: Consider Input: Question: Did Ida's father have more than one child? Passage:The Anglo-Saxon Chronicle indicates that Ida's reign began in 547, and records him as the son of Eoppa, grandson of Esa, and great-grandson of Ingwy. Likewise, the Historia Brittonum calls him as the son of Eoppa and the first king of Berneich or Bernicia. The Anglo-Saxon Chronicle elaborates that he ruled for twelve years and built the Bernician capital of Bamburgh Castle. Later, however, the Chronicle confuses his territory with the later Northumbria, saying that lla, historically a king of Deira rather than Bernicia, succeeded him as king after his death. Northumbria did not exist until the union of Bernicia with the kingdom of Deira; this happened for the first time under Ida's grandson thelfrith. The genealogies of the Anglo-Saxon kings attached to some manuscripts of the Historia Brittonum give more information on Ida and his family; the text names Ida's "one queen" as Bearnoch and indicates that he had twelve sons, naming among them Adda, thelric, Theodric, Eadric, Theodhere, Osmere and Ealric. Several of these are listed as kings. One of them, Theodric, is noted for fighting against a Brittonic coalition led by Urien Rheged and his sons. The genealogical preface to Chronicon ex chronicis names six sons, Adda, Bealric, Theodric, Ethelric, Osmere, and Theodhere, born to his wife and six born to concubines, Ocga, Alric, Ecca, Oswald, Sogor and Sogothere. Ida's successor, Glappa, does not appear among his sons in any of the early sources. Ida's descendants would rule Bernicia and later Northumbria.

Output: The Anglo-Saxon Chronicle indicates that Ida's reign began in 547, and records him as the son of Eoppa, grandson of Esa, and great-grandson of Ingwy
