Example Input: Question: In what city did Raiford major in communication? Passage:'Robert D. Raiford (December 27, 1927 November 17, 2017) was an American radio broadcaster and actor, best known for his political/social commentaries delivered during The John Boy and Billy Big Show, a morning radio program heard on stations throughout the American South. He was from Concord, North Carolina and majored in communication at the University of South Carolina. Raiford got his start in broadcasting in 1944 by calling play by play at baseball games. His first real radio job was at WEGO (AM) in Concord, North Carolina. Raiford has appeared in 28 movies, often portraying judge characters. He frequently closed his commentaries with the line "Who says that? I say that!", which also served as the title of a book containing excerpts from these segments. Early in his career, Raiford worked for WTOP radio and WTOP-TV, both CBS News affiliates in Washington, D.C.. His best-known work was a live radio broadcast on WTOP, a CBS Radio affiliate, covering the state funeral of President John F. Kennedy. He also worked at Charlotte radio station WBT. Raiford also hosted a show on WIST, which aired Charlotte's first telephone talk radio format. He later taught Communications at the University of North Carolina at Charlotte. From 1978 to 1986, Raiford was a news anchor and talk show host for Charlotte's NBC television affiliate. It was known as WRET-TV and then WPCQ-TV during his tenure there; it is now WCNC-TV. On the June 9, 2016, episode of The John Boy and Billy Big Show, John Isley ("John Boy") announced that Raiford had retired from the show, due to suffering a stroke the previous August that greatly affected his speech and mobility. Raiford had not delivered any commentaries during the intervening months, choosing to focus on his recovery instead.

Example Input: Question: How many soldiers did Britain send to World War I the year Roebuck arrived on the Western Front? Passage:As a boy, Roebuck worked as a trammer and after being sentenced to one month's imprisonment for stealing a watch in 1904, he enlisted in the York and Lancaster Regiment. Over the next seven years, he was stationed in India and Ireland and was promoted to lance corporal, but was demoted back to private in 1910 for "misconduct". He married in 1908 and had two children. Roebuck was discharged into the reserves in 1912 and likely returned to work as a miner prior to becoming a professional footballer in 1913. After Britain's entry into the First World War in August 1914, he was called up by the York and Lancaster Regiment and arrived on the Western Front in September 1914. On 18 October 1914, Roebuck recorded as "presumed dead" after an attack near Beaucamps-Ligny during the Race to the Sea. His death was confirmed by two comrades in January 1915. Roebuck is commemorated on the Ploegsteert Memorial to the Missing.

Example Input: Question: Were both Zwart partners born in the same country? Passage:Mike Phillips attempted to enter an A410 at the 24 Hours of Daytona in 2001, but did not attend the race. The Sports Racing World Cup had been renamed to the FIA Sportscar Championship, but the A410, now driven by Lupberger and Ben Collins, started the season as it had finished 2000; with a retirement, although it did last for 74 laps before blowing its engine with half an hour to go at Barcelona. Next up was the Donington Park of the European Le Mans Series, which saw both A410s entered; although the A410 of Patrick Lemarie did not make the start of the race, due to engine problems, Lupberger and Collins were classified 23rd, having retired after 54 minutes and 35 laps due to another gearbox problem. The 1000 km of Monza, part of the FIA Sportscar Championship, saw the first success for the A410; Collins and Lupberger brought their car home in second, 7 seconds behind the Ferrari 333SP-Judd of Giovanni Lavaggi and Christian Vann. The upturn in form continued at Spa-Francorchamps, where Collins and Lupberger brought the A410 home in fourth, a lap down, but having set the second fastest lap of the race. Lupberger and Collins were partnered by Harri Toivonen for the 24 Hours of Le Mans in the A410-001 chassis, whilst Zwart partnered Xavier Pompidou and Scott Maxwell in the other; neither finished, as the A410-001 retired due to fuel pump issue after 11 hours and 134 laps, and the other car crashed out after 15 hours and 66 laps. Having returned to the FIA Sportscar Championship, Collins and Lupberger took a pair of fourth-place finishes, at Brno and Magny-Cours. The team went even better at Donington Park; Collins and Lupberger won by almost a minute, for the car's maiden victory. The penultimate round of the season, held at Mondello Park, was a little less successful, as the team finished ninth overall, and sixth in the SR1 class. In the final race of the season, held at the Nurburgring, the car was disqualified from third place due to issues with its dimensions. Team Ascari finished the season in fourth, with 71 points; nine behind Racing for Holland in third, but 30 ahead of R&M in fifth. The team's one European Le Mans Series race resulted in them being classified in eighth, with 11 points.
