[EX Q]: 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.

[EX Q]: Question: When did the program on which song made its premier first air? Passage:A preview of the video was posted on AOL's PopEater.com, and subsequently on Bieber's VEVO channel, including behind the scenes clips of Bieber with the dancers, and highlights of the video with Usher and in front of a green screen. Bieber said, "It's really awesome to be able to work with professional dancers, you know, people that were in, like, ABDC, and also got an approval from choreographer Jamaica, who said Bieber was "killing it" and that she didn't have to give him any corrections. It made its premiere during the June 17, 2010 results show of the seventh season of So You Think You Can Dance, and was introduced by Usher after his performance of "OMG". It later premiered that night on VEVO and on June 18, 2010 on 20/20at the end of their show. The video features dance crews including, America's Best Dance Crew season 5 winners Poreotics, and Season 3's runner up Beat Freaks, as well as The Syrenz, LXD, Medea Sirkas, solo acts Simrin Player and Bboy Fly, and other dancers and crews. Singer/actress and model Katerina Graham makes a cameo in a scene with Poreotics. Bieber's best friend Ryan Butler, who appeared in the "One Time" video, also appears alongside Bieber, wearing a T-shirt advertising his Twitter account. According to Tamar Antai of MTV News the video "makes vague allusions" to clips for Busta Rhymes' "Pass the Courvoisier, Part II" and Chris Brown's "Wall to Wall". A backpack choreography scene with LXD recalls Usher's 1997 video for "You Make Me Wanna".

[EX Q]: Question: What country is Zeesen a part of? Passage:The name "Lord Haw-Haw of Zeesen" was coined in 1939 by the pseudonymous Daily Express radio critic Jonah Barrington, but this referred initially to Wolf Mittler (or possibly Norman Baillie-Stewart). When Joyce became the best-known propaganda broadcaster, the nickname was transferred to him. Joyce's broadcasts initially came from studios in Berlin, later transferring (because of heavy Allied bombing) to Luxembourg and finally to Apen near Hamburg, and were relayed over a network of German-controlled radio stations that included Hamburg, Bremen, Luxembourg, Hilversum, Calais, Oslo, and Zeesen. Joyce also broadcast on and wrote scripts for the German Büro Concordia organisation, which ran several black propaganda stations, many of which pretended to broadcast illegally from within Britain. His role in writing the scripts increased over time, and the German radio capitalized on his public persona. Initially an anonymous broadcaster, Joyce eventually revealed his real name to his listeners; and he would occasionally be announced as "William Joyce, otherwise known as Lord Haw-Haw". Urban legends soon circulated about Lord Haw-Haw, alleging that the broadcaster was well-informed about political and military events to the point of near-omniscience.
