Input: Consider Input: Question: Which of the two companies that posted previews  of Somebody to Love was founded first? 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".

Input: Consider Input: Question: What was architect's  age when the Wakeman obelisk was set in the square at Richmond, Yorkshire? Passage:The first obelisks may start to appear in the later 16th century and it is suggested that the obelisk on Compton Pike is Elizabethan in date. More securely dated is a series of obelisks which start to appear in the 18th century. The first of these was the Wakeman obelisk of 1702 by Nicholas Hawksmoor, which is set in the square at Richmond, Yorkshire. Probably several hundred obelisks exist in the British Isles dating from 18th and early 19th centuries. Most of these obelisks, which are often landmarks commemorate famous people and their achievements. At Stowe in Buckinghamshire an obelisk was erected in memory of Wolfe's victory at Quebec in 1752, while at the death of the Duke of Cumberland in 1765 was noted by an obelisk at Englefield Green in Surrey. Thomas Coke, Earl of Leicester, Coke of Norfolk the farming pioneer has a particularly fine obelisk, set up in the park he created at Holkham in Norfolk. Sometimes an obelisk was used to mark the site of a battle such as the obelisk on the site of English Civil War battlefield at Naseby in Leicestershire. Occasionally obelisks are used as mile markers, as on the Great North Road at a mile from Westminster. In Lincoln an elaborate obelisk was set up on the High Bridge in 1762–63 as a conduit for dispensing water, while Anthony Salvin used obelisks as water fountains on the Belton House estates in Lincolnshire.
