Example Input: Question: Did Eric Ashton win his first game against New Zealand? Passage:In 1954, Ashton was spotted playing rugby union during his national service in the Royal Artillery and was subsequently invited for a trial with Wigan. He attended the trial and was seen by the directors of the club as being a player with exceptional talent, after Wigan offered him a spot in their top level side he offered his home town club St. Helens the chance to sign him but they passed and he then signed for Wigan in 1955 for £150. He made his first representative later that year, appearing for Lancashire against New Zealand. He represented Rest of the World in the 11-20 defeat by Australia at Sydney Cricket Ground on 29 June 1957, and represented Great Britain & France in the 37-31 victory over New Zealand at Carlaw Park, Auckland on 3 July 1957. After signing for Wigan he quickly linked up with Welsh Billy Boston, and formed one of the most devastating right-hand side threequarters partnerships of modern times. Ashton played right-, i.e. number 3, in the 8-13 defeat by Oldham in the 1956–57 Lancashire County Cup Final during the 1957–58 season at Station Road, Swinton on Saturday 19 October 1957. He played and was captain in the 13–9 victory over Workington Town in the 1957–58 Challenge Cup Final during the 1957–58 season at Wembley Stadium, London on Saturday 10 May 1958, in front of a crowd of 66,109, such was the impact of both Ashton and Boston it led to Ashton being promoted as captain of the Wigan side after just two years at the club at the age of 22. It was a position he would go on to hold for the next twelve years. He made his international début at the age of 22 for the Great Britain side against France in 1957. He would go on to collect a total of 26 caps for the Great Britain side with his first Southern Hemisphere tour coming in 1957 as the British side competed in the World Cup. He was a true professional in every sense, being sent off just twice in his whole career and due to his professionalism, talent and intelligence he would go on to achieve a long and distinguished footballing career. Ashton's honours and achievements are nothing short of impressive, with 3 victorious Wembley Stadium Challenge Cup finals (out of a possible six), a Championship in 1960, a Lancashire Challenge Cup and two Lancashire League Championships as well as a BBC Floodlit trophy. He played , and was captain in Wigan's 30-13 victory over Hull F.C. in the 1958–59 Challenge Cup Final during the 1958–59 season at Wembley Stadium, London on Saturday 9 May 1959, in front of a crowd of 79,811.

Example Input: Question: How many engines does the Boeing bomber that land at Taichung International Airport have? Passage:Taichung International Airport was constructed during the era of Japanese rule and was named . The United States Air Force (USAF) had been garrisoning the base with two fighter squadrons until the Sino-American Mutual Defense Treaty came into force on March 3, 1955. The airport then expanded in 1954 according to the Sino-American Mutual Defense Treaty, and later renamed Ching Chuan Kang Air Base (CCK) in memory of General Qiu Qingquan. In 1966 the American Air Force established a joint forces air-base at CCK. It was the largest air force base in the Far East at the time, allowing Boeing B-52 Stratofortress bombers to land. During the Vietnam War, CCK became a depot for the USAF. The US Military used CCK and Shuinan Airport to run many of its long-distance Vietnam, Cambodia and Laotian bombing, scouting and cargo transport runs during the Vietnam War era. This base was shut down and most American facilities were removed after U.S. established diplomatic relations with the China in 1979.

Example Input: Question: Who is the founder of the company who completed sound design for the Hulk movie? Passage:Eric Bana commented that the shoot was, "Ridiculously serious... a silent set, morbid in a lot of ways." Lee told him that he was shooting a Greek tragedy: he would be making a "whole other movie" about the Hulk at Industrial Light & Magic. An example of Lee's art house approach to the film was taking Bana to watch a bare-knuckle boxing match. Computer animation supervisor Dennis Muren was on the set every day. One of the many visual images in the film that presented an acting challenge for Bana was a split screen technique employed by Lee to cinematically mimic the panels of a comic book page. This required many more takes of individual scenes than normal. Sound design was completed at Skywalker Sound. Muren and other ILM animators used previous technology from Harry Potter and the Chamber of Secrets (for the Dobby character) to create the Hulk with computer-generated imagery. Other software used included PowerAnimator, Softimage Creative Environment, Softimage XSI, and RenderMan Interface Specification. ILM started computer animation work in 2001, and completed in May 2003, just one month before the film's release. Lee provided some motion capture work in post-production.
