Example Input: Question: Who was Akbar's predecessor to the Mughal throne? Passage:Gauda was once the "capital of the ancient bhukti or political division of Bengal known as Pundravardhana which lay on the eastern extremity of the Gupta Empire." During the rule of the Sena Dynasty, in the 11th-12th century, Gauda was rebuilt and extended as Lakshmanawati (later Lakhnauti), and it became the hub of the Sena empire. Gauda was conquered by Muhammad bin Bakhtiyar Khalji in 1205. During the Turko-Afghan period, "the city of Lakhnauti or Gauda continued to function initially as their capital but was abandoned in 1342 by the Ilyas Shahi sultans in favour of Pandua because of major disturbances along the river course of the Ganga." "Pandua then lay on the banks of the Mahananda, which was the major waterway of the sultanate at the time. However, when the Mahananda too began to veer away from the site of Pandua in the mid-15th century, Gauda was rebuilt and restored to the status of capital city by the Hussain Shahi sultans"... With the ascent of Akbar to the Mughal throne at Delhi... the Mughals annexed the ancient region of Gauda in 1576 and created the Diwani of Bengal. The centre of regional power shifted across the Ganga to Rajmahal. Following the demise of the independent sultanate, the regional importance of the Gauda or Malda region declined irreversibly and the city of Gauda was eventually abandoned.

Example Input: Question: Which cup competition that Krul played in has a longer history? Passage:Krul returned to Newcastle as backup to first choice Steve Harper. He made his senior league debut on 8 August 2009 in the opening Football League Championship game of the season away to West Bromwich Albion, coming on as a half time substitute for the injured Harper.

He later played the full Football League Cup match against Huddersfield Town on 26 August 2009, which Newcastle won 4–3. Krul also started the 2–0 League Cup defeat to Peterborough. Against Swansea City on 28 November, he again came on to replace the injured Steve Harper. On 2 January, he played in the FA Cup Third Round tie against Plymouth Argyle, the game ending 0–0.

Example Input: Question: How many year's after the creation of Yale did Henry M. Hoenigswald serve as a research assistant? Passage:He was educated in the German Gymnasium, where he learned the classical languages, and trained as an Indo-Europeanist and a historical and comparative linguist in universities in Munich, Zurich, Padua, and Florence. His refugee status compelled these moves (his grandparents were Jewish, and by 1933 Jews were forbidden to attend German universities). In 1939 he escaped to the United States, where he was at first a research assistant at Yale. He taught at the University of Pennsylvania from 1948 until his retirement in 1985. He was a member of the Linguistic Society of America, of which he was elected President in 1958, and a member of the American Philosophical Society for more than 30 years. He was elected to the National Academy of Sciences. He spent a year at Oxford in 1976 and was elected a Corresponding Fellow of the British Academy in 1986.
