Teacher: Now, understand the problem? Solve this instance: Question: What is the seating capacity of Ullevål Stadion? Passage 1:In 1857, he enlisted as a private in Company K of the 7th Regiment of the New York National Guard, and was attached to the staff of Brig. Gen. William Hall. At the start of the American Civil War, Pierson helped organize the 1st New York Volunteer Infantry Regiment, and was appointed captain in May 1861. He was promoted several times and assumed command of the regiment on October 9, 1862, with the rank of colonel. Attached to the 3rd Corps, Army of the Potomac, he led the 1st New York in actions at the Seven Days Battles, Second Manassas and the Battle of Fredericksburg. After the Battle of Chancellorsville in May 1863, Colonel Pierson was honorably discharged and mustered out on May 25, 1863. For distinguished service, he was brevetted brigadier general of the United States Volunteers for "gallant and meritorious services."
 Passage 2:Edward J. DeBartolo Corporation formed a joint venture with Homart Development Company, a shopping mall development subsidiary of the department store chain Sears, to begin development on Castleton Square in 1971. DeBartolo announced the mall's development in January of that year and began groundbreaking soon afterward. The original plans called for a Y-shaped enclosed mall with three anchor stores: Sears, J. C. Penney, and Rike Kumler Co. (Rike's), a department store chain based out of Dayton, Ohio. The mall would be situated on 82nd Street just outside the Interstate 465 beltway within the Castleton neighborhood on the northeastern side of Indianapolis. It was the second of three malls built by DeBartolo as a part of its expansion into Indianapolis, following Lafayette Square Mall in 1968 and preceding Washington Square Mall in 1974. The company chose to build on the northeastern side of the Indianapolis metropolitan area, as the area was projected for further suburban growth in the intervening years. Similarly, research conducted by Sears showed a trend in residential growth to the city's northeast side, thus creating a market which the chain deemed suitable for a new store. To accommodate for mall traffic, the Indiana Department of Transportation expanded 82nd Street to a four-lane divided highway. Federated Department Stores (now Macy's, Inc.), then-owners of the Rike's chain, confirmed that the third anchor of Castleton Square would instead be Lazarus, a Columbus, Ohio-based chain then also under their ownership. Also confirmed as tenants for the mall by 1972 were a Kroger supermarket, an F. W. Woolworth Company dime store, and a three-screen movie theater. Inline tenants would include Robert Hall Clothes, Hickory Farms, Kinney Shoes, Zales Jewelers, Waldenbooks, and Orange Julius.
 Passage 3:Nordre Aker is best known as the site of Ullevål Stadion, the stadium of the Norway national football team. Tenants on club level have been Vålerenga Fotball, and FK Lyn before the latter club faced a series of relegations. Vålerenga originally has no connection to Nordre Aker, whereas Lyn origins from the north of the borough, around Kringsjå. Ullevål is traditionally the area of Ullevål IL, and though this club has dropped association football from its programme, it operates the bandy field Bergbanen adjacent to Ullevål Stadion. Other bandy clubs in the borough are Tåsen IL and Skeid Bandy. Skeid Bandy, a part of the multi-sports-club Skeid, has a headquarters at Nordre Åsen, but the club has a geographic connection to Sagene borough. Lyn is also a multi-sports club, SFK Lyn, which in addition to football is involved in Nordic skiing. Other skiing clubs in the district are IL Koll (which also professes in volleyball), Kjelsås IL (which also professes in football) and Nydalen SK (which also professes in orienteering). Korsvoll IL is best known for football and handball. IK Akerselva is a floorball club competing on the highest national level.
