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.
