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: How long is the river in San Antonio where Jones drove cotton carrying wagon along the river? Passage:Walter "Wiley" Jones was born in Madison County in northeastern Georgia, on July 14, 1848. His parents were George Jones, a white planter, and Jones' slave, Anne, who had six children by George Jones: Matthew (who superintended the construction of the Wiley Jones Street Car Line), Thomas, Julia (wife of Ben Reed), Wiley, Taylor, and James (who managed many of Wiley's businesses). Wiley received his nickname because of his mischievous nature. At the age of five, he moved to Arkansas with his master and more than forty fellow slaves. They settled on the Governor Byrd plantation. George Jones died in 1858. Anne was called his wife in an 1889 biography of Jones, and she believed that George had promised to free herself and her children upon his death, but no manumission papers were found, and the family was kept as slaves and sold by the estate administer, Peter Finerty, to James Yell, a lawyer and planter in Pine Bluff. Jones worked as a houseboy and carriage driver for his new master. When Jones was ten, he was given to Yell's only son, Fountain Pitts Yell, on the occasion of Pitts Yell's marriage. Pitts was a state representative from 1860 to 1861. During the American Civil War, James Yell became a Major General of the Arkansas State Militia, and Pitts became a colonel in Company S of the 26th Arkansas Infantry Regiment in the Confederate Army. James Yell's was transferred to the Confederate States Army in the summer of 1861, and James left the service and moved to Texas. Jones served for Pitts during the war until Pitts' death in 1864 at the Battle of Pleasant Hill in Louisiana. Jones then joined James Yell and his family in Waco, Texas. There, he served as a porter in a mercantile house for one year. He was then hired to drive a wagon carrying cotton on a route along the Brazos River to San Antonio.
