Example Input: Question: What year did the grammar school that Richard Burt attended open? Passage:Burt was born in Perth to Gladys (née MacMurtrie) and Frederick Julius Augustus Burt. His grandfather was Septimus Burt, who was also a member of parliament and served as Attorney-General of Western Australia. Burt attended Guildford Grammar School, and after leaving school went to the North-West, working variously as a crayfisherman, stationhand, pearler, and tin miner. He opened a machinery and hardware store in Cue in 1935, and in 1939 was elected to the Cue Road Board, of which he eventually became chairman. Burt entered parliament at the 1959 state election, narrowly winning the seat of Murchison from Everard O'Brien of the Labor Party. He transferred to the new seat of Murchison-Eyre at the 1968 election, and retired from parliament at the 1971 election. After leaving politics, Burt held directorships with various mining companies. He died in Perth in November 1993, aged 84, and had married Mary Groom in 1937, with whom he had three sons.

Example Input: Question: How many Roman monuments are located in Mérida, Spain? Passage:Mérida has been populated since prehistoric times as demonstrated by a prestigious hoard of gold jewellery that was excavated from a girl's grave in 1870. Consisting of two penannular bracelets, an armlet and a chain of six spiral wire rings, it is now preserved at the British Museum. The town was founded in 25 BC, with the name of Emerita Augusta (meaning the veterans – discharged soldiers – of the army of Augustus, who founded the city; the name Mérida is an evolution of this) by order of Emperor Augustus, to protect a pass and a bridge over the Guadiana river. Emerita Augusta was one of the ends of the Vía de la Plata (Silver Way), a strategic Roman Route between the gold mines around Asturica Augusta and the most important Roman city in the Iberian Peninsula. The city became the capital of Lusitania province, and one of the most important cities in the Roman Empire. Mérida preserves more important ancient Roman monuments than any other city in Spain, including a triumphal arch and a theatre.

Example Input: Question: How old was John Yates when he began investigating the News of the World phone hacking scandal? Passage:In March 2006, several men nominated for life peerages by then Prime Minister Tony Blair were rejected by the House of Lords Appointments Commission. It was later revealed they had loaned large amounts of money to the governing Labour Party, at the suggestion of Labour fundraiser Lord Levy. Suspicion was aroused by some that the peerages were a quid pro quo for the loans. This resulted in three complaints to the Metropolitan Police by Scottish National Party MP Angus MacNeil, Plaid Cymru parliamentary leader Elfyn Llwyd, and a third individual who continues to remain unidentified, as a breach of the law against selling honours. The investigation was headed by Assistant Commissioner John Yates who later resigned over the News of the World phone hacking scandal. During the investigation various members of the Labour Party (including Tony Blair), the Conservatives and the Liberal Democrats were questioned, and Labour's Lord Levy was arrested and later released on bail. The investigation continued to have political impact throughout, as a range of stories continued to leak from the police investigation and damaged the government and Labour Party.
