In this task, you're given a passage, further information available on a particular linked term from the statement, and a question. Your job is to generate the answer to the question by using the information provided. If there is no clear answer obtainable, output 'none'.

Input: Consider Input: Passage: New College dominates the south side of the street. At the western end of the street is the King's Arms public house on the north corner, a favourite with Oxford University students, and the Indian Institute (now the home of The James Martin 21st Century School) to the south. On the north side is the Holywell Music Room, an historic chamber music venue built in 1742. Opposite a small cul-de-sac, Bath Place, leads via a small winding footpath to the historic Turf Tavern public house close to the old city wall. The wall remains, in places, and follows the course of Holywell Street to the south, partly through New College. The buildings on the corner of Holywell Street and Mansfield Road, along with the Alternative Tuck Shop, are owned by Harris Manchester College, and are used as student accommodation.
 Link Information: The college started as the Warrington Academy in 1757 Question: When was the educational institution that owns the buildings on the corner of Holywell Street and Mansfield Road established?

Output: Answer: 1757 


Input: Consider Input: Passage: As designed in 1931, the He 46 was a two-seat sesquiplane of mixed construction. The upper wing was swept back 10°. This is a common trick when a change in an aircraft's design moves the center of gravity to the rear; rather than moving the whole wing back to counter for the shift, it is easier to simply angle the wings back slightly, which requires very little change to the basic design, or even the overall structure of the wing. (The similarly angled wings on the Fairey Swordfish are due to just such a mid-program change to the weight distribution of the aircraft.) The tailplane was mounted high and braced by struts. The undercarriage was fixed, and the tail was fitted with a skid rather than a wheel. The He 46 prototype first flew in late 1931; its flight characteristics were good, but design improvements were incorporated. The small lower wing was removed, while the mainplane was increased in area by 22% and braced to the fuselage, transforming the He 46 into a parasol-wing monoplane. A more powerful engine was added to the second prototype, and a single 7.92 mm (.312 in) MG 15 machine gun for the rear seat was added to the third prototype.

Input: Consider Input: Passage: In 2006, Klausner presided over United States v. Ancheta, the federal prosecution of Jeanson James Ancheta of Downey, California, the first botnet-related prosecution in U.S history. Following Ancheta's guilty plea, Klausner sentenced Ancheta to 57 months in prison for various botnet-related crimes. In 2016, Klausner presided over a copyright case filed by the estate of Spirit guitarist Randy Wolfe against Led Zeppelin founders Robert Plant and Jimmy Page. The estate of Wolfe alleged that Wolfe was entitled to a writing credit for the song "Stairway to Heaven"; Klausner ruled in April 2016 that a jury could find "substantial similarity" between the elements of the two songs. In another copyright case arising from the Star Trek fan film Prelude to Axanar, Klausner rejected various motions by both parties in January 2017, setting the stage for a civil trial on the matter to go forward. The parties settled the suit. In August 2017, Klausner dismissed a class-action lawsuit filed by boxing fans who contended that the 2015 Floyd Mayweather Jr. vs. Manny Pacquiao boxing match was deceptively marketed because Pacquiao failed to disclose a shoulder injury that affected his performance. Klausner ruled that fans of sporting events have no right to have the event meet their expectations for excitement. In October 2017, Klausner ruled in favor of the plaintiff Coachella Music Festival in a lawsuit against the fledgling "Filmchella" film festival, finding that the names were likely to cause consumer confusion.

Output: Answer: none
