Example Input: Question: During what years was "Joliet" Jake Blues in prison? Passage:Blues vocalist and petty criminal "Joliet" Jake Blues is paroled on good behavior grounds from Joliet Correctional Center after serving three years of a five-year sentence, and is picked up by his blood brother Elwood in his Bluesmobile, a battered, decommissioned police car. Elwood demonstrates its capabilities by jumping an open drawbridge. The brothers visit the Roman Catholic orphanage where they were raised, and learn from Sister Mary "the Penguin" Stigmata and old friend Curtis that it will be closed unless $5,000 in property taxes is collected. Jake offers to steal the money, but Sister Mary is offended. During a sermon by the Reverend Cleophus James at the Triple Rock Baptist Church, Jake has another idea: they can re-form their band, the Blues Brothers, which disbanded while Jake was in prison, and raise the money to save the orphanage.

Example Input: Question: How many students are enrolled at the University of Bergen? Passage:A legal purge took place in Norway after WWII in which 53,000 people were sentenced for treason and 25 were executed. The post-war years saw an increased interest in Scandinavism, resulting in Scandinavian Airlines System in 1946, the Nordic Council in 1952 and the Nordic Passport Union along with the metric system being introduced. Reconstruction after the war gave Norway the highest economic growth in Europe until 1950, partly created through rationing private consumption allowing for higher industrial investments. The Labor Party retained power throughout the period and maintained a policy of public planning. The University of Bergen was created in 1946. The 1950s saw a boom in construction of hydroelectricity and the state built the steel mill Norsk Jernverk and two aluminum works. State banks such as the State Housing Bank, the State Educational Loan Fund and Postbanken allowed for governmental control over private debt. Oslo hosted the 1952 Winter Olympics.
