Question: What position did Yosuke Saito hold during the development of Cross Gate? Passage:Dragon Quest X was developed by Square Enix and Armor Project, a company founded by series creator Yuji Horii. This was the first modern Dragon Quest title to be developed by Armor Project and Square Enix, as earlier mainline entries had been handled by external companies. The CGI opening was handled by Square Enix's CGI department Visual Works. The game was directed by Jin Fujisawa, who also directed Dragon Quest IX. The scenario was written by Fujisawa, with later scenario support by Atsushi Narita. Horii served as game designer and general project director. Series art designer Akira Toriyama returned to design the characters, while the music was composed by series veteran Koichi Sugiyama. One of the chief planners was Naoki Yoshida, who had worked on earlier Dragon Quest spin-offs, and was later assigned as the director of Final Fantasy XIV and its reboot . A newcomer to the series was producer Yosuke Saito, formerly a staff member at Cavia who worked as a programmer on the Drakengard series before producing its spin-off game Nier. After Cavia closed in 2010, Saito formed his own company Orca, which was chosen by Square Enix to support the development of Dragon Quest X. Due to this, work had to be scrapped on a PlayStation Vita version of Nier. Saito had earlier worked with MMORPGs when he was involved with the development of Cross Gate (2001). A second newcomer was Chikara Saito who, after working on Dragon Quest X during its development alongside Cross Treasures, would take over as the game's director in 2013.

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.
