Example Input: Question: What year was the university Lawrence Lessig taught at founded? Passage 1:Promoted lieutenant-colonel in 1852, and colonel (and commanding officer of the 5th Uhlans) in 1853, Manteuffel was sent on important diplomatic missions to Vienna and St Petersburg. In 1857 he was promoted to major-general and chief of the Prussian Military Cabinet (the King's military advisers). He gave strong support to the Prince Regent's plans for the reorganization of the army. In 1861 he was violently attacked in a pamphlet by Karl Twesten (1820–1870), a Liberal leader, whom he had wounded in a duel, for which Manteuffel insisted on being briefly imprisoned. He was promoted to lieutenant-general for the coronation of William I on 18 October 1861 and saw active service in that rank in the Danish War of 1864, then at its conclusion was appointed civil and military governor of Schleswig. In the Austrian War of 1866 he first occupied Holstein and afterwards commanded a division under Vogel von Falkenstein in the Hanoverian campaign, then in July succeeded Vogel in command of the Army of the Main.
 Passage 2:Remix culture, sometimes read-write culture, is a society that allows and encourages derivative works by combining or editing existing materials to produce a new creative work or product. A remix culture would be, by default, permissive of efforts to improve upon, change, integrate, or otherwise remix the work of copyright holders. While a common practice of artists of all domains throughout human history, the growth of exclusive copyright restrictions in the last several decades limits this practice more and more by the legal chilling effect. In reaction, Harvard law professor Lawrence Lessig who considers remixing a desirable concept for human creativity has worked since the early 2000s on a transfer of the remixing concept into the digital age. Lessig founded the Creative Commons in 2001 which released Licenses as tools to enable remix culture again, as remixing is legally prevented by the default exclusive copyright regime applied currently on intellectual property. The remix culture for cultural works is related to and inspired by the earlier Free and open-source software for software movement, which encourages the reuse and remixing of software works.
 Passage 3:Sabita Devi (1914–1965) was a Hindi film actress in Indian cinema. She is stated to be one of the "prominent" leading ladies of the "pioneering era" of Indian cinema along with Mehtab, Bibbo, Durga Khote, Gohar, Devika Rani and Seeta Devi.

After initially working with British Dominion Films Ltd., Calcutta, she shifted to Bombay and performed mainly in films produced by Sagar Movietone with her co-star in most films being Motilal.

 Passage 3:Anna Kraus, Op. 30 is a radio opera in one act by composer Franz Reizenstein. The work uses an English language libretto by Christopher Hassall to tell the tragic tale of a German woman who is forced to leave her country due to oppression from the Nazi regime, as the Nazis did not like her political views. The opera was commissioned by the British Broadcasting Corporation following the popular success of Reizenstein's 1951 cantata Voices of Night. The opera premiered on 25 July 1952 on BBC Third Programme with conductor Norman Del Mar leading the BBC Symphony Orchestra and singers Victoria Sladen (as Anna) and Lloyd Strauss-Smith (as Pavel). It was submitted by the BBC later that year for the Prix Italia. Critical reaction to the work was mixed. The New Statesman described the work as "engaging" and a "worthwhile experiment". The Annual Register wrote that the opera "suffered from the composer's emotion being too closely engaged in the sufferings of the heroine, a refugee from political oppression".
