Input: Consider Input: Passage: The castle was built in the 13th century by Přemysl Otakar II or his son Václav II to guard royal paths and local mines. The first known owner was Mikuláš Winkler, burgrave of Loket Castle, who sold Hauenštejn to the monastery in Doksany. The monastery exchanged it for another building with King John of Luxemburg. His son Charles IV enlarged the castle‘s domain. The castle frequently changed its keepers in the second half of the 14th century and the 15th century but it more or less remained royal property. The rich family of Šlik that started silver mining near Jáchymov won the castle in the 16th century. The Šliks rebuilt the castle in the Renaissance style after a fire in 1600. In 1663 the Šliks sold the castle to the Saxe-Lauenburg ducal family and it became part of the Ostrov domain. The castle was in the hands of the Baden family from 1689. When the last male member of the family died in 1771, the property of the Badens in Bohemia was inherited by the royal family of Maria Theresa. The Habsburgs sold it to the Buquoy family in 1837. Countess Gabrielle Buquoy started to rebuild the castle in a Romantic style. Ferdinand Buquoy continued the reconstruction under the influence of historism, taking its examples from England (Windsor, Arundel, Belvoir, Lancaster or Oxford) and Bavaria (Hohenswangau, Lahneck).

Input: Consider Input: 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.

Output: How many universities did Boston have the year Vassos moved there?

Racing from a base at Woodbine Racetrack in Toronto, at age two his best performances were wins in an allowance race at Gulfstream Park in Florida, where he equalled the track record for 6.5 furlongs, and a win in Woodbine's Victoria Stakes. At age three, Alydeed won five of his ten starts. Near the end of April 1992, he was sent to Churchill Downs in Louisville, Kentucky where he won the Derby Trial. Based on his strong performance, his handlers decided to run him in the second leg of the U.S. Triple Crown series, the Preakness Stakes where he ran second to Pine Bluff. Back at Woodbine Racetrack, he won the Plate Trial Stakes then ran away from the field in the final quarter of a mile to win Canada's most prestigious race, the Queen's Plate. In the second leg of the Canadian Triple Crown series, the Prince of Wales Stakes, Alydeed was sent off as the prohibitive favorite at 1/9 odds. However, on a muddy Fort Erie Racetrack, Alydeed ran second to Benburb. Alydeed then elected to skip the third jewel of the Canadian Triple Crown opting for the Grade 1 Travers Stakes at Saratoga Race Course where he finished eighth to Thunder Rumble as the 8-5 favourite.
