Example Input: Question: Who earned the bronze medal in the event where the Austrian athlete earned the gold? Passage:Sonja Henie of Norway won her third straight gold medal in the ladies' singles figure skating event, her last Olympic medal as she turned professional shortly after the Games. Karl Schäfer of Austria also successfully defended his men's singles figure skating title from Lake Placid. Sweden swept the medals in the cross-country 50 km, as did Norway in the Nordic combined. Norway's Ivar Ballangrud was the most successful athlete, winning three golds and a silver in speed skating and taking his career total to seven Olympic medals. Other multiple medal winners were Oddbjørn Hagen of Norway (one gold, two silvers), Ernst Baier of Germany (one gold, one silver), Joseph Beerli of Switzerland (one gold, one silver), Erik August Larsson of Sweden (one gold, one bronze), Birger Wasenius of Finland (two silvers, one bronze), Olaf Hoffsbakken of Norway (two silvers), Fritz Feierabend of Switzerland (two silvers) and Sverre Brodahl of Norway (one silver, one bronze).

Example Input: Question: How old was the Liberal Unionist MP when he died? Passage:Morton first stood for Parliament at the 1885 general election, when he contested Hythe, and was unsuccessful again in Christchurch at the 1886 election. He won a seat three years later, when he was elected at a by-election in October 1889 as the Member of Parliament (MP) for Peterborough, after the death of the Liberal Unionist MP John Wentworth-FitzWilliam, becoming the 81st new MP since the general election in 1886. His victory was unexpected, and when the result was declared he said that he hoped his victory would be seen as a gesture of conciliation Ireland. He was re-elected in 1892, and raised in Parliament the issue of the appointment of Justices of the Peace (magistrates) in April 1893. In November that year, 280 Gladstonian MPs met the Lord Chancellor, Lord Herschell, in the House of Lords to discuss the system. Morton led the response to the Lord Chancellor's explanation and defence of the existing system of appointment, and denounced the reliance on advice from Lord Lieutenants who were entirely dependent on what Morton called "class cliques". He was also a member of a Select Committee set up to examine the accommodation provided for members and officials of the House of Commons. Great Western Railway

Example Input: Question: How many games did Millwall lose the season they had 11 consecutive clean sheets in? Passage:In the 1925–26 season Millwall had 11 consecutive clean sheets, a Football League record, which they hold jointly with York City and Reading. Millwall became known as a hard-fighting Cup team and competed in various memorable matches, notably defeating three-time league winners and reigning champions Huddersfield Town 3–1 in the third round of the 1926–27 FA Cup. In the 1927–28 season Millwall won the Third Division South title and scored 87 goals at home in the league, an English record which still stands. Matches against Sunderland and Derby County saw packed crowds of 48,000-plus in the 1930s and 1940s. Their 1937 FA Cup run saw Millwall reach the semi-finals for the third time, and a fifth-round game against Derby still stands as Millwall's record attendance of 48,762. Millwall were the 11th best supported team in England in 1939, despite being in the Second Division. Millwall were one of the most financially wealthy clubs in England. The club proposed plans to improve the Den and signed international players. Winger Reg 'JR' Smith was capped twice, scoring two goals for England in 1938. The Lions were pushing for promotion to the First Division toward the end of the decade, but one week into the 1939–40 season, World War II broke out and Millwall were robbed of their aim.
