In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it. Your job is to determine which sentence(s) from the passage can be used to search for further information needed to answer the question.

Example Input: Question: How old was the manager of the Movistar team when the 2015 Vuelta a Espana began? Passage:The first five stages took place in and around Andalusia in southern Spain; the 2014 Vuelta had also started there. The first stage was a team time trial along the coast from Puerto Banús to Marbella. The next four stages were fairly flat, although Stage 2 finished on a moderately difficult climb. The sixth stage started in Córdoba and finished in Sierra de Cazorla in Jaén on another moderately difficult climb. The seventh stage then returned to Andalusia for the first major difficulty of the race: the first-category summit finish at La Alpujarra. The route then continued along the eastern coast of Spain, with a medium-mountain seventh stage and another first-category summit finish at Benitachell on Stage 9. There was one more medium-mountain stage on Stage 10, taking the riders into the Province of Castellón. This was followed by a transfer that took the riders into Andorra for a three-day spell, beginning with the first rest day. The eleventh stage took place entirely in Andorra; though it was only in length, it included six categorised climbs, including a summit finish, and was described by Eusebio Unzué (the manager of the Movistar team) as "the toughest Vuelta stage that he has seen in more than 30 years". Stage 12 took the riders back into Spain for a fairly flat stage, before three consecutive stages with summit finishes. These took place in the mountains of Cantabria and Asturias and were followed by the race's second rest day. The final week of the race included no summit finishes: the first stage was a individual time trial in Burgos and was then followed by three mixed stages that took the riders nearer to the final stage of the race, a sprint stage in Madrid. For the first time, the race organisers also held a women's race on the same day as the final stage, using the same circuit. This race – called La Madrid Challenge by La Vuelta – was won by Shelley Olds.

Example Output: The eleventh stage took place entirely in Andorra; though it was only in length, it included six categorised climbs, including a summit finish, and was described by Eusebio Unzué (the manager of the Movistar team) as "the toughest Vuelta stage that he has seen in more than 30 years"

Example Input: Question: Which country represented in 1970 at the World Popular Song Festival is larger, the country Ted Mulry participated for or the country Jacques Michel participated for? Passage:Belgium was represented at the 1970 edition by Daliah Lavi, famous for her role in Casino Royale (1967), the James Bond parody featuring Woody Allen as well with Samantha Gilles in 1987 ending second with the song Hold Me. Lavi performed the chanson "Prends L'Amour" and ended up 13th in the Grand Final (the contest had two semi-finals and one final). The Netherlands delegated world-known jazz singer Rita Reys with the song "Just Be You", a composition by her husband Pim Jacobs. Czech singer Helena Vondráčková sang "Uncle Charlie" a novelty song inspired by Charlie Chaplin. Other famous 1970 participants were 1969 Eurovision winner Frida Boccara for France, Jacques Michel for Canada and Ted Mulry for Australia, who scored a national number 1 hit with his entry. Winner of the 1st WPSF was Israel with the duo Hedva & David. More than 2 million copies of their winning entry "Ani Holem Al Naomi" ("I Dream Of Naomi") were sold worldwide, giving a serious credibility boost to the new Festival.

Example Output: Other famous 1970 participants were 1969 Eurovision winner Frida Boccara for France, Jacques Michel for Canada and Ted Mulry for Australia, who scored a national number 1 hit with his entry

Example Input: Question: How long had the Jodrell Bank Observatory been in operation when Lyne retired? Passage:Andrew Geoffrey Lyne FRS (born 13 July 1942) is a British physicist. Lyne is Langworthy Professor of Physics in the School of Physics and Astronomy, University of Manchester, as well as an ex-director of the Jodrell Bank Observatory. Despite retiring in 2007 he remains an active researcher within the Jodrell Bank Pulsar Group. Lyne was educated at The Portsmouth Grammar School, the Royal Naval School, Tal Handaq, Malta and at St. John's College at the University of Cambridge (natural sciences), continuing to the University of Manchester for a PhD in Radio Astronomy. Lyne writes that he is "mostly interested in finding and understanding radio pulsars in all their various forms and with their various companions. Presently, I am most occupied with the development of new multibeam search systems at Jodrell and Parkes, in order to probe deeper into the Galaxy, particularly for millisecond pulsars, young pulsars and any that might be in binary systems."

Example Output:
Despite retiring in 2007 he remains an active researcher within the Jodrell Bank Pulsar Group
