question:
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.

question:
Question: How many artists had won the gold medal from the Royal British Society of Sculptors before Montford did? Passage:Montford was president of the Victorian Artists Society 1930–32. His generally good work as president was occasionally marred by a certain lack of tact. Some of Montford's best work about this period included the bronzes, "Water Nymph" and "Peter Pan", now in the Queen Victoria Gardens, Melbourne, and "The Court Favourite" in the Flagstaff Gardens, Melbourne. Other work includes relief portraits of eight Australian statesmen in the King's Hall, Parliament House, Canberra, and the war memorial for the Australian Club, Sydney. He was greatly encouraged and pleased on learning in 1934, that his statue of Adam Lindsay Gordon at Melbourne had been awarded the gold medal of the Royal British Society of Sculptors for the best piece of sculpture of the year. Another excellent piece of work is his vigorous statue of John Wesley in front of Wesley Church, Melbourne. His George Higinbotham near the treasury is less successful. Other examples of Montford's work are the memorials to Carlo Catani (St Kilda), William Benjamin Chaffey (Mildura), Sir Ross Macpherson Smith (Adelaide), and 'Pioneer Women' (Sydney). Montford is represented in the National Gallery of Victoria in Melbourne by "Atalanta", the "Spirit of Anzac", and two busts, and he is also represented in the Art Gallery of South Australia in Adelaide. He provided a model from which a portrait bust of Socrates was carved for the University of Western Australia by Victor Wager in 1932.

question:
Question: Which of the counties that feeds the Lac qui Parle River has a larger land area? Passage:The source of the river is Lake Hendricks on the boundary of Lincoln County, Minnesota, and Brookings County, South Dakota. It issues from the lake in Hendricks, Minnesota, and flows northeastwardly through northwestern Lincoln County as an intermittent stream on the Coteau des Prairies, a morainic plateau dividing the Mississippi and Missouri River watersheds, into western Yellow Medicine County, where it flows off the Coteau, dropping 250 feet (76 m) in eight miles (13 km). Continuing northeastwardly through flat till plains with occasional willows and cottonwoods along its banks, the river flows into eastern Lac qui Parle County, passing to the east of Dawson. It flows into the Minnesota River just below Lac qui Parle Lake in Lac qui Parle State Park, approximately ten miles (15 km) northwest of Montevideo, after flowing through a wooded valley in which it drops 210 feet (64 m) in 18 miles (29 km). Lac qui Parle Lake was formed by a delta at the mouth of the Lac qui Parle River, and is maintained by a dam.
