Example Input: 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.

Example Input: Question: What age was John McCormack the year that DGOS was founded? Passage:The Dublin Grand Opera Society (DGOS) was founded in 1941 by Captain (later Colonel) William O'Kelly and a group of opera enthusiasts with John McCormack as its patron. The shows were cast with local singers and a volunteer chorus. Initially the music was provided by the orchestra of the Irish Army music school, and later by the Radio Eireann Symphony Orchestra. The Society put on two one-week seasons of opera throughout the years of World War II. After the war ended the DGOS presented performances by European opera companies such as the Opera-Comique, Hamburg Opera and the Netherlands Opera. From the mid 1950s to 1966, the Society, concentrated on Italian opera with the help of sponsorship from the Italian government. During that time numerous Italian stars and rising stars of the day appeared there, including Luciano Pavarotti who sang in Rigoletto, La traviata, and La bohème. The Italian sponsorship ended in 1966, but the Arts Council of Ireland and the Bord Fáilte (Ireland's tourist board) continued to provide guarantees for any financial losses. New opera companies were brought in, including the Romanian National Opera and the Prague National Theatre.
