Example Input: Question: When was the organization founded to which Cross received appointment as a chevalier? Passage:Colonel Marie Augstin Gaston Cros (known as Gaston Cros) (6 October 1861 – 10 May 1915) was a French army officer and archaeologist. He was born in Alsace and was displaced when that territory was incorporated into the German Empire. He joined the French Army as a lieutenant and saw action in Tonkin before spending several years surveying in Tunisia, receiving the honours of membership of Vietnamese and Tunisian orders and appointment as a chevalier of the Legion of Honour. In 1901 Cros was appointed head of the French archaeological expedition to Girsu, Iraq to continue the work of Ernest de Sarzec. His work over the next five years included the tracing of the thick city wall and for his work there received a letter of commendation from Gaston Doumergue, the Minister of Fine Arts, and the award of the Golden Palms of the Ordre des Palmes Académiques. Promoted to lieutenant-colonel, Cros served in the French protectorate of Morocco from 1913, seeing action in the Zaian War.

Example Input: Question: What was the Hertford Town club record the year that Scott Neilson joined? Passage:Neilson was a member of Norwich City's youth teams at the age of 11, went on to Charlton Athletic and also won schoolboy honours for Wales. His senior career started at his brother Tony's club Hertford Town of the Isthmian League in 2005. He was top goalscorer for the reserves when he made his debut on 25 October in an Isthmian League Associate Members Trophy game against Clapton, before going on to play 15 games in his first season and scoring one goal. In his second season, he played 24 games upping his goal tally by another nine, before he earned a move in December 2006 to Ware – a second club where his brother also played. In one game in January 2008, Neilson came off the bench to score four goals for Ware against Tilbury in a 5–2 victory. The goals went towards Neilson's total of 23 from 40 games for Ware in the Isthmian League First Division North, helping Ware towards the end-of-season play-offs. However, he left Ware before the end of the season to join Cambridge City in March 2008 for the rest of the club's Conference South campaign.

Example Input: Question: What was the circulation of the Daily Express the year that Cameron stopped working there? Passage:Cameron began as an office dogsbody with the Weekly News in 1935. Having worked for several Scottish newspapers and for the Daily Express in Fleet Street, he was rejected for military service in World War II. After the war, his experience of reporting on the Bikini Atoll nuclear experiments turned him into a pacifist and a founding member of the Campaign for Nuclear Disarmament. He continued to work for the Express until 1950, after which he briefly joined Picture Post, where he and photographer Bert Hardy covered the Korean War, winning the Missouri Pictures of the Year International Award for "Inchon". Tom Hopkinson, the editor of Picture Post, lost his job as publisher when he defended the magazine's coverage of atrocities committed by South Korean troops at a concentration camp in Pusan. Cameron wrote, "I had seen Belsen, but this was worse. This terrible mob of men - convicted of nothing, un-tried, South Koreans in South Korea, suspected of being 'unreliable'." The founder of the Hulton press, Edward G. Hulton, decided to "kill" the story.
