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" (), 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 () 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 () argued instead that the Nanhai measuring point was located in Central Vietnam. Historian of astronomy Chen Meidong () and historian of Chinese science Nathan Sivin have since agreed with Zeng's position in their respective books about Guo Shoujing.

Question: Which of the gaming consoles that the Jaguar had superior hardware compared with was developed first? Passage:Joergen Bech, who previously worked as a developer at Innerprise Software during 1990, decided to work once again as a game programmer after dropping out of international marketing studies in 1994 and landed for the job by one of his contacts who had connection with an employee at Bethesda Softworks, who are best known for The Elder Scrolls and their most recent Fallout titles. Bethesda was interested in expanding their business to video game consoles and Joergen was hired for work on the Jaguar, due to the company receiving free Alpine Development Kits from Atari Corporation and for its superior hardware compared with other systems at the time such as the Sega Genesis and Super NES. Originally he was tasked in making a conversion of a basketball game from PC but decided to create a 2D title in order to understand the Jaguar's hardware, along with another programmer who already was familiarized with the system, after Joergen deemed the PC basketball game as a "steep learning curve" to convert, due to it being in pseudo-3D and being written on C language, which he had little to no experience with them and it was then decided that he should port Protector to Genesis, which was a conversion of Datastorm for Amiga alongside with the original authors of the game at Bethesda's Media Technology division on Denmark, with him providing the sound driver for the port, but otherwise he was not fully involved with the project and although completed it was ultimately never published due to many console, PC and multimedia titles competing for shelf space, with no prototypes of the Genesis version of Protector being found to date.
