Example Input: Question: How many years had Gary Tallon been playing professionally by the year Boulding turned professional? Passage:Boulding maintained his links with football and trained with Doncaster Rovers, and in 1998 he joined non-league Hallam near his home in Sheffield. His form at Hallam attracted the interest of a number of league clubs, and Boulding was offered a trial by Mansfield Town. He was given a contract by the Division Three side and turned professional in 1999, which brought an end to his tennis career. He made his debut with Mansfield in a League Cup game against Nottingham Forest on 11 August 1999 as a late substitute for Gary Tallon, before his first league game came three days later against Cheltenham Town. He had to wait until his 12th game as a professional to register his first goal when he scored in a 2–1 victory over Shrewsbury Town on 23 October. He eventually finished his first season with six goals with Mansfield coming 17th but 17 points above Carlisle United, the only side to be relegated out of The Football League.

Example Input: Question: Is the political party that held a Second Congress in Brussels still active? Passage:Yakov Hanecki was born in Warsaw, then in the Russian Empire, the son of Stanislav von Fürstenberg, a beer manufacturer of German descent, who had adopted Poland as his homeland. In 1896 he joined the Social Democracy of the Kingdom of Poland (SDKP - later the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL)) led by Rosa Luxemburg and her lover, Leo Jogiches. He moved to Germany in 1901 and studied in rapid succession at Berlin, Heidelberg, and Zurich universities. From 1902, he was a professional revolutionary, normally based in Cracow, under Austrian rule, organising the transport of illegal literature across the Russian border. In August 1903, as a member of the Main Administration of the SDKPiL, he was one of two Polish delegates to the Second Congress of the Russian Social Democratic Labour Party (RSDLP) in Brussels. The Congress later adjourned to London, under pressure from the Belgian police, and there the RSDLP split into its Bolshevik and Menshevik factions, but Hanecki and the other Polish delegate, Adolf Warski, did not make the journey to London, having failed to agree terms on which the RSDLP and SDKPiL could collaborate.

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.
