Teacher: Now, understand the problem? Solve this instance: Question: How many months long was the Danish War of 1864? Passage 1: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. A Jewess by birth, she changed her name to find acceptability in Hindi cinema like the other Anglo-Indian and Jewish actresses of her time, Sulochana (Ruby Myers), Seeta Devi (Renee Smith), Madhuri (Beryl Claessen), and Manorama (Erin Daniels). 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. Some of the popular films with Motilal were Dr. Madhurika (1935) and Kulvadhu (1937) directed by Sarvottam Badami. Their first film together was Shaher Ka Jadoo (1934), which was also Motilal's debut film, and then Lagna Bandhan (1936) both directed by Kaliprasad Ghosh. She acted in Silver King (1935) with Motilal. It was an action film directed by C. M. Luhar, which became a "huge success".
 Passage 2: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 3:Page attended the Okemos Montessori School (now called Montessori Radmoor) in Okemos, Michigan, from 1975 to 1979, and graduated from East Lansing High School in 1991. He attended Interlochen Center for the Arts as a saxophonist for two summers while in high school. Page holds a Bachelor of Science in computer engineering from the University of Michigan, with honors and a Master of Science in computer science from Stanford University. While at the University of Michigan, Page created an inkjet printer made of Lego bricks (literally a line plotter), after he thought it possible to print large posters cheaply with the use of inkjet cartridges—Page reverse-engineered the ink cartridge, and built all of the electronics and mechanics to drive it. Page served as the president of the Beta Epsilon chapter of the Eta Kappa Nu fraternity, and was a member of the 1993 "Maize & Blue" University of Michigan Solar Car team. As an undergraduate at the University of Michigan, he proposed that the school replace its bus system with a personal rapid transit system, which is essentially a driverless monorail with separate cars for every passenger. He also developed a business plan for a company that would use software to build a music synthesizer during this time.
