Example Input: Question: Which publication that Cannon contributed more substantial articles to came into existence first? Passage:Helped by his association with The Guardian, Cannon was able to contribute more substantial articles to the Los Angeles Times and the Chicago Sun-Times, and to underground magazines such as Creem. He wrote the 1970 documentary film London Rock, focusing on the UK's counterculture movement. He recalls that, together with Rolling Stone journalists David Dalton and Jonathan Cott, he joined Granada Television documentary-makers such as Jo Durden-Smith, John Sheppard and Michael Darlow in devising "prime-time networked shows designed as anthems of the revolution". Among these late-1960s projects, he says that the Johnny Cash at San Quentin TV special was his idea, and he "share[s] credit" for the ideas behind the concert films The Doors Are Open and The Stones in the Park. He also directed the film of Frank Zappa's performance at the 1970 Palermo Pop Festival, for RAI, Italy's national public broadcaster.

Example Input: Question: Was the coach that Culverhouse hired younger than the person he replaced? Passage:Former Atlanta Falcons coach Leeman Bennett was named by owner Hugh Culverhouse as the replacement for retired head coach John McKay. Other candidates interviewed included Buccaneer defensive coordinator Wayne Fontes, Seattle Seahawks defensive coordinator Tom Catlin, former Michigan Panthers head coach Jim Stanley, former New England Patriots head coach Ron Meyer, Washington Redskins quarterback coach Jerry Rhome, former Pittsburgh Steelers defensive coordinator Bud Carson, and former Florida Gators coach Charley Pell. Bennett was an unexpected choice, as Fontes had long been considered to be the leading candidate and had the near-unanimous support of the players and existing staff. Culverhouse almost gave Fontes the job without conducting an interview process, before having second thoughts and soliciting recommendations from McKay, Tex Schramm, and Dan Rooney. Described as "heartbroken", Fontes learned while attending a scouting combine in Arizona that he had been passed over for the job. Bennett indicated that nobody who had been a candidate for the head coaching job would be hired as an assistant, ending speculation that he might retain Fontes or bring in his former assistant Jim Stanley. Fontes eventually accepted the defensive coordinator position with the Detroit Lions.

Example Input: Question: In what country is Nelson, Caerphilly located? Passage:Nelson was originally called Ffos-y-Gerddinen ("ditch of the rowan"), a relatively flat piece of land at the southern extremity of the Taff Bargoed Valley to the south of the hamlet of Llancaiach. It existed on a drovers trail from the South Wales coast towards Merthyr Tydfil and onwards to Brecon and Mid Wales, where an enterprising man built a coaching inn that he called Nelson, possibly after Admiral Lord Nelson and his victory at the Battle of Trafalgar. Had it not been for the development of the South Wales coalfield, Nelson would have remained just a coaching inn surrounded by fields. When the Llancaiach Colliery was developed from 1811, it created a need for new housing for the workers and heavy transport for the coal, which spilled onto the flat lands below the colliery.
