Example Input: Question: Which of the two cities where McCartney was scheduled to headline has more residents? Passage:On 15 February 2016, McCartney announced two initial festival dates in Europe for the upcoming summer. These two headlining performances at Pinkpop Festival in Landgraaf, Netherlands and Rock Werchter in Werchter, Belgium were revealed before the initial revelation of the "One on One" tour. These tours would feature mostly similar elements of the "One on One" performances yet with a condensed set list to allot for festival curfew limits and less stage elements given restrictions. In the wake of the passing of notable Beatles and McCartney producer George Martin, McCartney announced the initial "One on One" dates for North America and Europe. In North America, McCartney's visit to Fresno, California would mark his first performance in the city, and his performances in North Little Rock and Sioux Falls would be his first performances in the states of Arkansas and South Dakota respectively. Elsewhere in North America, McCartney would perform in Portland after an eleven-year absence following his 2005 'US' tour. The two shows in Vancouver would follow his previous performance in the city at the BC Place stadium in 2012, yet this tour would feature two shows in the neighboring Rogers Arena after the pyrotechnics during his concert at BC Place accidentally damaged the stadium's new roof. McCartney's Seattle show would mark his shortest absence from any North American city on the tour announced currently, as he performed at the city's Safeco Field during the inaugural year of the 'Out There' tour. McCartney announced a performance on 16 March in Minneapolis at the Target Center. This show would take place on 4 May 2016, less than two years after McCartney's last performance in the city at the adjacent baseball stadium sharing a corporate sponsor with the arena, Target Field. Due to high demand of tickets a second show in Minneapolis was announced the next day and would take place on 5 May.

Example Input: Question: How old was Stalin the year that the Meskhetian Turks were forced out of Meskheti? Passage:The Meskhetian Turks first arrived in Azerbaijan at the end of the nineteenth century, and more followed in 1918-1920. However, migration to Azerbaijan increased dramatically after World War II when the Soviet Union was preparing to launch a pressure campaign against Turkey. Vyacheslav Molotov, then Minister of Foreign Affairs, demanded to the surrender of three Anatolian provinces (Kars, Ardahan and Artvin); thus, war against Turkey seemed possible, and Joseph Stalin wanted to clear the strategic Turkish population situated in Meskheti, located near the Turkish-Georgian border which were likely to be hostile to Soviet intentions. Thus, in 1944, the Meskhetian Turks were forcefully deported from the Meskheti region in Georgia and accused of smuggling, banditry and espionage in collaboration with their kin across the Turkish border. Nationalistic policies at the time encouraged the slogan: "Georgia for Georgians" and that the Meskhetian Turks should be sent to Turkey "where they belong". Joseph Stalin deported the Meskhetian Turks to Central Asia (especially to Uzbekistan), thousands dying en route in cattle-trucks, and were not permitted by the Georgian government of Zviad Gamsakhurdia to return to their homeland.

Example Input: Question: When was the university that Thomas Kenan graduated from in 1857 founded? 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.
