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 many years were The Screamers together before Roessler joined the band? Passage:Paul Roessler was born on August 27, 1958, in New Haven, Connecticut. In 1974, he moved to West Los Angeles where he met and befriended future Germs band members Darby Crash and Pat Smear at University High. After graduating from high school, Roessler went on to study classical music at California State University, Northridge, for a few semesters before leaving in early 1978 to join innovative electropunk band, The Screamers. After two successful years, The Screamers found themselves rapidly disintegrating as a band, causing Roessler to leave in January 1980, and would then go on to play in Nervous Gender with former Germs drummer Don Bolles as well as in Geza X and the Mommymen. After a few months of going between bands, he was recruited by Nina Hagen to join her for an upcoming European tour. After touring Europe and America with Hagen, they recorded Nunsexmonkrock. Before Roessler's second tour with Hagen, Pat Smear from the Germs joined the band. Later, when Smear left the band, Roessler left also. In 1981, he formed the band Twisted Roots with Smear and sister Kira Roessler. During this time, he was playing with 45 Grave, Josie Cotton, DC3 (with Dez Cadena of Black Flag) and Crimony (with Mike Watt) as well. Roessler was also doing sessions with many other bands such as the Dead Kennedys and Saccharine Trust. Roessler has continued to work with Nina Hagen and Josie Cotton. From 1998 to 2011, Roessler worked as the in-house producer at Satellite Park Studio with Geza X. In 2006, Roessler released an autobiographical poetry book entitled Eight Years (Brass Tacks Press, 2006). He continues to write his own music and is currently recording a new album. In 2010, Roessler produced and played keyboards on Nina Hagen's gospel album Personal Jesus (Universal). He has been a member of the Fancy Space People with Don Bolles and Nora Keyes since 2009. In October 2011, they joined the Smashing Pumpkins on their "Other Side of the Kaleidyscope" tour.

Example Input: Question: How old was Thomas Kenan's grandfather when he died? Passage:Thomas Stephen Kenan (February 12, 1838 – December 23, 1911) was a Confederate soldier, and later a politician. His parents were Sarah Rebecca Graham and Owen Rand Kenan; he was the grandson of U.S. Congressman Thomas Kenan and great-grandson of Revolutionary War general James Kenan. He started his education in Duplin County, North Carolina at Old Grove Academy in Kenansville (the town was named for his great-grandfather in 1818). Later he spent a year at Central Military Institute in Selma, Alabama. Thomas spent his freshman year of college at Wake Forest in June. Thomas then transferred his sophomore year to the University of North Carolina, where he would graduate in 1857. He studied law for two years with Judge Pearson at Richmond Hill where he practiced law in Kenansville. After graduation and during the Civil War he became Captain of the Duplin Rifles in the Confederate States Army, elected lieutenant colonel of the 43rd North Carolina Infantry Regiment in April 1862, and was promoted to colonel later that year. He was wounded at the Battle of Gettysburg. While on an ambulance train, he and his older brother James Kenan were both captured; they were then imprisoned on Johnson's Island, Ohio. On March 22, 1865, he was released on parole but never switched sides during the war. On his return home he was elected to the state legislature from 1865 to 1867. Later that year he ran for Congress and lost. Not letting that defeat end his political career, he moved to Wilson, North Carolina, where he became mayor and was elected North Carolina Attorney General, serving from 1877 to 1885. In May 1868 he married Miss Sallie Dortch, but they had no children; Sallie died in 1916.
