Example Input: Question: How many soldiers died in the war that Charles K. Erwin fought in? Passage 1:The source of the river is Lake Hendricks on the boundary of Lincoln County, Minnesota, and Brookings County, South Dakota. It issues from the lake in Hendricks, Minnesota, and flows northeastwardly through northwestern Lincoln County as an intermittent stream on the Coteau des Prairies, a morainic plateau dividing the Mississippi and Missouri River watersheds, into western Yellow Medicine County, where it flows off the Coteau, dropping 250 feet (76 m) in eight miles (13 km). Continuing northeastwardly through flat till plains with occasional willows and cottonwoods along its banks, the river flows into eastern Lac qui Parle County, passing to the east of Dawson. It flows into the Minnesota River just below Lac qui Parle Lake in Lac qui Parle State Park, approximately ten miles (15 km) northwest of Montevideo, after flowing through a wooded valley in which it drops 210 feet (64 m) in 18 miles (29 km). Lac qui Parle Lake was formed by a delta at the mouth of the Lac qui Parle River, and is maintained by a dam.
 Passage 2:Born in Washington, Lycoming County, Pennsylvania, Erwin settled in Portage, Wisconsin in 1853. From 1855 to 1868, Erwin lived in Jo Daviess County, Illinois and then in Stephenson County, Illinois. During the American Civil War, Erwin served in the 45th Illinois Volunteer Infantry Regiment. In 1868, Erwin moved to Tomah, Wisconsin and was in the mercantile business. From 1879 to 1882 and 1886, Erwin served on the Tomah Board of Education and was president of the school board. From 1882 to 1889, Erwin served in the Wisconsin State Senate and was a Republican. In 1889, Erwin served as postmaster for Tomah, Wisconsin. In 1902, Erwin moved with his family to Milwaukee, Wisconsin. Erwin died suddenly in Savanna, Illinois just as he was about get on a train for a trip to Omaha, Nebraska.
 Passage 3:During the 2006/07 season, Liang reached at least the second round of qualifying in every ranking event. At the Northern Ireland Trophy, he beat Robert Stephen 5–0 before falling to David Gilbert 0–5 in qualifying. However, at the Grand Prix, Liang came top of his qualifying group, above more experienced players such as Gerard Greene and Barry Pinches. He finished fourth in his group at the round-robin stage, and although he did not progress to the next round, he did beat former world champion and world number one Stephen Hendry 3–0. At the UK Championship, he lost in the second round of qualifying to Jamie Burnett 7–9. In the following ranking event, the Malta Cup, he lost to Joe Jogia 3–5, again in the second round of qualifying. He qualified for the Welsh Open, his third ranking tournament, by beating Dene O'Kane, Joe Jogia and Mark Davis. He met Nigel Bond again in the last 48, this time losing only 3–5.

Example Input: Question: Which of the two universities in Ware's home state was founded first? Passage 1:Berg was born in Minneapolis, Minnesota, and expressed an interest in football at an early age. At one point, she played quarterback on a local team that included future Oklahoma Sooners head football coach Bud Wilkinson. At the age of 13, Berg took up golf in 1931 at the suggestion of her parents; by 1934, she began her amateur career and won the Minneapolis City Championship. The following year, Berg claimed a state amateur title. She attended the University of Minnesota where she was a member of Kappa Kappa Gamma sorority. She came to national attention by reaching the final of the 1935 U.S. Women's Amateur, losing to Glenna Collett-Vare in Vare's final Amateur victory. Berg won the Titleholders in 1937. In 1938, she won the U.S. Women's Amateur at Westmoreland and the Women's Western Amateur. With a victory in the 1938 Titleholders Championship and a spot on the winning Curtis Cup team as well, Berg was selected as the Associated Press Woman Athlete of the Year, the first of three times she earned the honor. In 1939, Berg won her third consecutive Titleholders, although she was unable to compete in the U.S. Women's Amateur due to an operation on her appendix.
 Passage 2:Before Hammer's successful career (with his mainstream/commercial popularity lasting approximately between the mid-1980s until the late-1990s) and his "rags-to-riches-to-rags-and-back saga", Burrell formed the Christian rap music group Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as "K.B." and then eventually M.C. Hammer once it was produced), was later released by Jon Gibson (aka "J.G."). This was Contemporary Christian music's first rap hit ever (by anyone), in particular by a Caucasian (Gibson) and/or from a duo. The track appeared on Gibson's album Change of Heart (1988), and "Son of the King" showed up on Hammer's debut album Feel My Power (1987) as well as the re-released version Let's Get It Started (1988). Burrell, along with Tramaine Hawkins, performed with Gibson's band doing several concerts in various venues such as the Beverly Theatre in Beverly Hills.
 Passage 3:Ware grew up in the Galveston, Texas region, hoping to play football at the University of Texas. He said "I was going to Texas. All they had to do was lie to me and tell me I was going to play quarterback once I got there. Thank goodness they told me the truth [that] they were going to move me to defense". After graduating from Dickinson High School, Ware instead played at the University of Houston, where he won the Heisman Trophy in 1989, along with the Davey O'Brien Award, the latter award given to the most outstanding college quarterback of the year. That year, his junior year, he threw for 4,699 yards, 44 touchdowns, and set 26 NCAA records. Many of the records were thanks to the innovative use of the run and shoot offense, which his successor, David Klingler, also used to great effect. The Cougars ended the season ranked the #14 team in the nation by the Associated Press. He then declared for the NFL Draft, foregoing his senior year.

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.
