[Q]: Question: Was Nathan Sivin alive when Han Zhenhua claimed that Nanhai referred to the Scarborough Shoal? Passage:The People's Republic of China and the Republic of China (Taiwan) claim that Chinese people discovered the shoal centuries ago and that there is a long history of Chinese fishing activity in the area. The shoal lies within the nine-dotted line drawn by China on maps marking its claim to islands and relevant waters consistent with United Nations Convention on the Law of the Sea (UNCLOS) within the South China Sea. An article published in May 2012 in the PLA Daily" states that Chinese astronomer Guo Shoujing went to the island in 1279, under the Yuan dynasty, as part of an empire-wide survey called "Measurement of the Four Seas" (四海测验), however, no such 13th century map has been made public by China nor such evidence on the existence of the map is known. In 1979 historical geographer Han Zhenhua (韩振华) was among the first scholars to claim that the point called "Nanhai" (literally, "South Sea") in that astronomical survey referred to Scarborough Shoal. In 1980 during a conflict with Vietnam for sovereignty over the Paracel Islands (Xisha Islands), however, the Chinese government issued an official document claiming that "Nanhai" in the 1279 survey was located in the Paracels. Historical geographer Niu Zhongxun defended this view in several articles. In 1990, a historian called Zeng Zhaoxuan (曾昭璇) argued instead that the Nanhai measuring point was located in Central Vietnam. Historian of astronomy Chen Meidong (陈美东) and historian of Chinese science Nathan Sivin have since agreed with Zeng's position in their respective books about Guo Shoujing.

[Q]: Question: How many employees did Columbia Pictures have the year The Living Desert was released? Passage:Before 1953, Walt Disney's productions were distributed by Winkler Pictures, Powers Pictures, Universal Pictures (Oswald the Lucky Rabbit shorts), Columbia Pictures (1930–1932), United Artists (1932–1937) and RKO Radio Pictures (1937–1953). However, a dispute over the distribution of Disney's first full-length movie, The Living Desert, in the True-Life Adventures series of live-action documentary featurettes in 1953 led to Walt and his older brother Roy O. Disney to form its wholly owned subsidiary, the Buena Vista Film Distribution Company, Inc. (BVDC), to handle North American distribution of their own products. RKO refused to distribute the film. The name "Buena Vista" came from the street in Burbank, California, where the Disney Studios was located (and remains to this day). Buena Vista's first release was the Academy Award–winning live-action feature The Living Desert on November 10, 1953, along with Toot, Whistle, Plunk and Boom, Buena Vista's first animated release. Notable subsequent releases include the foreign film, Princess Yang Kwei-Fei (Most Noble Lady), released in US theaters in September 1956, The Missouri Traveler in March 1958, and The Big Fisherman in July 1959 (the first third-party production financed by Disney).
