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: How old was Mark Tulin in 1965? Passage:The band originated from a surf rock-influenced garage rock group, the Sanctions, in 1965. The Sanctions, which included James Lowe (vocals, guitar), Mark Tulin (bass guitar), Ken Williams (lead guitar), and Michael "Quint" Weakley (drums), recorded 12 cover songs on an acetate disc on March 27, 1965, in a home studio owned by Russ Bottomley. For their next set of recordings on September 29, 1965, the group, then known as Jim and the Lords, was joined by keyboardist Dick Hargrave, who left shortly afterwards to pursue a career in graphic arts. The songs went unreleased until Heartbeat Productions distributed the 2000 album, Then Came The Electric Prunes, which was commended for its good sound quality, considering the circumstances in which it was recorded. Back to a quartet, the band, while rehearsing in a garage, met a real estate agent named Barbara Harris. Harris had connections in the music industry, and introduced the group to Dave Hassinger to record demos at Sky Hill Studios. Hassinger, who had been working as the resident sound engineer at RCA Studios, recently completed development for The Rolling Stones' album, Aftermath, and expressed a desire to produce a record. He suggested to the group that they change their name, and they considered a list of alternatives. According to Lowe, the name Electric Prunes started off as a joke, but he eventually convinced other band members, saying, "It's the one thing everyone will remember. It's not attractive, and there's nothing sexy about it, but people won't forget it." As a result of the recordings, a single, featuring a cover of the Gypsy Trips' folk rock tune, "Ain't It Hard", and the Lowe-penned song, "Little Olive", was released in early 1966, but failed to chart.
