Example Input: Question: How long had Fenway Art School been operating the year Vassos moved to Boston? Passage:Vassos moved to Boston, Massachusetts in 1919, where he attended the Fenway Art School at night. He studied alongside American artist John Singer Sargent and worked as an assistant for Joseph Urban. In 1924 he moved to New York, where he attended the Art Students League of New York, studying under George Bridgman, John Sloan, and others. He opened his own studio creating window displays for department stores, like Wanamakers, murals, and advertisements for Saks Fifth Avenue, Bonwit Teller, and Packard Motor Cars in his unique black and white illustrated style. At the same time, he illustrated a series of books by Oscar Wilde for E.P. Dutton followed by others including Phobia on which he based his life-long design focus on psychology, his area of expertise as noted by Fortune Magazine's list of top designers in the country. He entered the emergent field of industrial design and was hired by rapidly-growing RCA Victor, under the leadership of David Sarnoff, who discovered Vassos while painting murals at the WCAU skyscraper in Philadelphia. The company had recently acquired Victor Phonograph, built Radio City, and owned NBC Broadcasting, but needed to amplify and modernize their radio manufacturing business. By hiring Vassos, an up-and-coming industrial designer who created their first Styling department, launched Vassos on a four-decade relationship with the company for whom he designed hundreds of items, while also consulting for numerous other clients like Coca-Cola, Waterman, Universal Artists, Remington, and the United States Government. Vassos's work as an interior designer included the Chrysler Building apartment of photographer Margaret Bourke-White, Nedick's Hot Dog stands, displays for RCA in department stores and the World's Fair,and many others for which he employed modular furniture. He eschewed trendy styles like the extreme-streamlined look, popular in the 1930s, and favored the clean, modern look unadorned with unnecessary elements. He expressed his design philosophy for magazines like Pencil Points and in lectures on modern design and art. Although he was hailed as a top designer in the United States during the 1930s, he slipped away from the spotlight of his industrial design peers like Raymond Loewy, Henry Dreyfuss, and Norman Bel Geddes, largely because he did not open a large firm. Unique among the industrial designers of the 20th century, his work was focused on the intersections between interior decorating, furniture design, and the shapes of phonographs, radios and televisions. His contributions include creating a futuristic living room including television, the slide rule dial on radios, emphasis on the haptic experience of media (knobs and buttons), and the "user experience," years before this term was coined.

Example Input: Question: When did the person who overthrew President Momoh achieve the rank he held at the time? Passage:On 29 April 1992, a group of Junior soldiers in the Sierra Leone Army led by a 25 year old Captain Valentine Strasser overthrew President Momoh, and Sierra Leone was under Military rule from 1992 to 1996 during the civil war. Sierra Leone returned to a democratically elected government when the military Junta under Brigadier General Julius Maada Bio who had ousted Strasser in a coup in 1996, handed the presidency to Ahmad Tejan Kabbah of the SLPP after his victory in the 1996 Sierra Leone presidential election. However, on 25 May 1997, the Sierra Leone military overthrew President Kabbah in a coup and Major General Johnny Paul Koroma became the country's Head of State. However, in February 1998, a coalition of West African Ecowas armed forces led by Nigeria reinstated President Kabbah by military force, and the leaders of the coup were executed after they were sentenced to death by a Sierra Leone military court. In January 2002, President Kabbah announced the ending of the civil war with the help and support of Ecowas, the British government, the African Union, and the United Nations. Sierra Leone has had an uninterrupted democratic government from 1998 to present.
