In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: In what country did Boreal make his first appearance outside Germany? Passage:On his first race of 2002, Boreal made his first appearance outside Germany when he contested the Dubai Sheema Classic at Nad Al Sheba Racecourse on 23 March. Ridden by Kieren Fallon, he stayed on strongly in the straight and finished third behind Nayef and the New Zealand gelding Hades with the other beaten horses including Marienbard and Tobougg. On 7 June, the colt was sent to England and attempted to become the first German-trained horse to win the Coronation Cup over one and a half miles at Epsom Racecourse. Racing on soft ground, he started 4/1 third favourite behind Kutub (Preis von Europa, Gran Premio del Jockey Club, Singapore Gold Cup), and Storming Home. The other three runners were Marienbard, Zindabad (Yorkshire Cup), and Pawn Broker (Arc Trial). Fallon positioned the German challenger just behind the leader Zindabad before taking the lead entering the straight and tracking across to the stands-side (outside) rail. Boreal went clear of his rivals in the last quarter mile and won by three and a half lengths from Storming Home with Zindabad six lengths back in third. After training the first German winner at Group One level in Britain since Star Appeal took the 1975 Eclipse Stakes, Schiergen said, "He travels smoothly on good ground but is more at home on soft. It's a special thrill to have a winner in Britain, and extra-special when it's a Group 1 at the home of the Derby."

Example Input: Question: Which location has a higher elevation, where the sixth stage finished or where the first category of the seventh stage finish? 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 Input: Question: What years are the setting for Davidson's first novel? Passage:When the war ended, he returned to the Keystone Agency and travelled all over Europe as a freelance reporter. It was during one of these trips that he came up with the idea for his first thriller, The Night of Wenceslas (1960). The novel is set in Czechoslovakia during the Cold War, and tells the story of young Nicolas Whistler, a 24-year-old Londoner whose business trip to Prague goes horribly awry. The Night of Wenceslas was an instant success, inviting favourable comparisons with such luminaries as Eric Ambler. Davidson became one of the handful of living writers to have their first novel appear in a green Penguin jacket. The book won the Crime Writers' Association's Gold Dagger Award (the top prize for crime and spy fiction in Britain) as well as the Authors' Club First Novel Award. It was filmed as Hot Enough for June (1964), with Dirk Bogarde in the role of Whistler.
