Example Input: Question: Who was the older of the two - Joe Airey, or the original member of the radar team that Airey joined? Passage 1:This was the first World Series game ever played in Colorado. At 4 hours 19 minutes, it became the longest nine-inning game in World Series history until game five of 2017. Game 3 was also the 600th World Series game ever played. Starting pitcher Daisuke Matsuzaka pitched five innings of scoreless ball and left in the sixth with no runs allowed. The Red Sox struck first with a six-run third inning. Rookie Jacoby Ellsbury hit a leadoff double, moved to third on Dustin Pedroia's single, and scored on David Ortiz's double. After Manny Ramirez was intentionally walked, Mike Lowell's single scored two more runs. J. D. Drew popped out before Ramirez was thrown out at home on Jason Varitek's single with Lowell advancing to third. After Julio Lugo walked to load the bases, Matsuzaka hit a two-run single for his first base hit and RBI in the Major Leagues. Ellsbury capped the scoring with his second double of the inning to knock Colorado starter Josh Fogg out of the game. The Rockies' bats came to life in the sixth and seventh innings against a normally-solid but now-shaky Boston bullpen. After Matsuzaka walked two straight in the sixth with one out, reliever Javier López allowed back-to-back RBI singles to Brad Hawpe and Yorvit Torrealba. Mike Timlin allowed two straight leadoff singles in the seventh before NLCS MVP Matt Holliday brought the Rockies to within one run with a three-run home run off Hideki Okajima. Brian Fuentes gave back those runs in the eighth by walking Lugo with one out and allowing a subsequent single to Coco Crisp before Ellsbury and Dustin Pedroia, who had four and three hits, respectively, on the night (the first time in World Series history two rookies had at least three hits in a game) hit back-to-back RBI doubles, raising Boston's lead to 9–5. Jonathan Papelbon came on for a four-out save, getting Holliday to fly out on one pitch, leaving runners on first and second. Jason Varitek would tack on Boston's tenth run in the top of the ninth off of LaTroy Hawkins with a sacrifice fly, scoring Mike Lowell who, not generally considered a stolen base threat, had just stolen third base—the first time a Red Sox baserunner stole third base in the World Series since 1975—after hitting a leadoff single and moving to second on a sacrifice bunt. Papelbon came back out in the bottom of the ninth to complete the save, getting the first two outs before surrendering a two-out triple to Brad Hawpe, then finishing the game with a groundout from Yorvit Torrealba. The Red Sox took Game 3 by a final score of 10–5.
 Passage 2:Airey was born in Oldham, Lancashire on 25 August 1894. He joined Robert Watson-Watt in 1924, and was an original member of the radar team, responsible for masts and support equipment. He was Senior Technical Officer at Telecommunications Research Establishment. Alongside Arnold Wilkins, Airey is credited with having discovered Bawdsey Manor, Ordfordnessas a site for the Air Ministry department that was significant in the history of radar. In his book "Three Steps to Victory" Robert Watson-Watt proclaims Joe Airey's greatest constructional achievement as the installation of a mast atop the Great Pyramid at Cheops. During World War I, Airey was a member of the Dunsterforce in the Persia and the Middle East. By the time of his retirement, he was Station Engineer at the Royal Radar Establishment. He was appointed a Member of the Order of the British Empire (MBE) for his services by King George VI in his Birthday Honours on 14 June 1945. Airey died in Poole Dorset on 10 February 1976.
 Passage 3:The Venom entered service with the Royal Air Force (RAF), where it was used as a single-seat fighter-bomber and two-seat night fighter. A dedicated model for aerial reconnaissance was also operated by the Swiss Air Force. The Venom functioned as an interim stage between the first generation of British jet fighters – straight-wing aircraft powered by centrifugal flow engines such as the Gloster Meteor and the Vampire – and later swept wing, axial flow-engined combat aircraft, such as the Hawker Hunter and de Havilland Sea Vixen. Accordingly, the type had a relatively short service life in the RAF, being withdrawn from frontline operations by the service in 1962 as a result of the introduction of more capable designs. However, it was used in combat during the Suez Crisis, the Malayan Emergency, and the Aden Emergency.

Example Input: Question: Which artist that MNEK worked with on their albums sold more records, Madonna or Kylie Minogue? Passage 1:The Great Game began on 12 January 1830 when Lord Ellenborough, the President of the Board of Control for India, tasked Lord William Bentinck, the Governor-General, to establish a new trade route to the Emirate of Bukhara. Britain intended to gain control over the Emirate of Afghanistan and make it a protectorate, and to use the Ottoman Empire, the Persian Empire, the Khanate of Khiva, and the Emirate of Bukhara as buffer states between both empires. This would protect India and also key British sea trade routes by stopping Russia from gaining a port on the Persian Gulf or the Indian Ocean. Russia proposed Afghanistan as the neutral zone. The results included the failed First Anglo-Afghan War of 1838, the First Anglo-Sikh War of 1845, the Second Anglo-Sikh War of 1848, the Second Anglo-Afghan War of 1878, and the annexation of Kokand by Russia.
 Passage 2:Initially, Springsteen recorded demos for the album at his home with a 4-track cassette recorder. The demos were sparse, using only acoustic guitar, electric guitar (on "Open All Night"), harmonica, mandolin, glockenspiel, tambourine, organ, synthesizer (on "My Father's House") and Springsteen's voice. The songs also have sparse composition, and many are simple three chord songs. After he completed work on the demos, Springsteen brought the songs to the studio and worked with the E Street Band. in April 1982 on rock versions; these sessions are commonly referred to as "the Electric Nebraska Sessions." Only Springsteen and Jon Landau had any decision-making power in this process. They felt certain songs were too personal, and the raw, haunting folk essence present on the home tapes could not be duplicated or equaled in the band treatments; the tracks they felt this way about made up the album "Nebraska." However, eight of the 12 tracks that went on the 1984 album "Born in the U.S.A." were composed of "Electric Nebraska" success stories. They were led by "Born in the U.S.A.," which was completed on May 3, 1982; "Downbound Train," recorded April 28, 1982; "Cover Me," recorded at The Hit Factory, New York on Jan. 25, 1982; "I'm On Fire," recorded at The Power Station on May 11, 1982; "Glory Days," recorded at The Power Station on May 5, 1982; "Darlington County," recorded at The Power Station on May 13, 1982; "Working On the Highway," recorded April 30 and May 6, 1982, and "I'm Going Down," recorded on May 12 or 13, 1982.

Example Input: Question: Who did the reinforcements oppose in the Battle of the Dneiper? Passage 1:The business was founded in 1953, when Ottavio and Rosita Missoni set up a small knitwear workshop in Gallarate, Italy. They presented their first collection under the Missoni label in Milan in 1958. The business prospered, with the support of fashion editor Anna Piaggi, then at Arianna magazine. Rosita met the French stylist Emmanuelle Khanh in New York in 1965, which led to a collaboration and a new collection the following year. In April 1967, they were invited to show at the Pitti Palace in Florence. Rosita told the models to remove their bras, supposedly because they were the wrong color, and showed through the thin lamé blouses. The material became transparent under the lights and caused a sensation. The Missonis were not invited back the following year, but the business grew; a new factory in Sumirago was built in 1969. Missoni designs were championed in the USA by Diana Vreeland, editor of American Vogue, and a Missoni boutique was opened in Bloomingdales.
