Question: Question: Who was the leader of the Porte in 1912? Passage:The modern Albanian-Serbian conflict has its roots in the expulsion of the Albanians in 1877-1878 from areas that became incorporated into the Principality of Serbia. Prior to the outbreak of the First Balkan War, the Albanian nation was fighting for a national state. At the end of 1912, the Porte recognised the autonomy of Albanian vilayet. These events for Albanian autonomy and Ottoman weakness were viewed at the time as directly threatening the Christian population of the region with extermination. The Balkan League (comprising Serbia, Montenegro, Greece and Bulgaria) jointly attacked the Ottoman Empire and during the next few months partitioned all Ottoman territory inhabited by Albanians. The Kingdom of Serbia and the Kingdom of Greece occupied most of the land of what is today Albania and other lands inhabited by Albanians on the Adriatic coast. Montenegro occupied a part of today's northern Albania around Shkoder. The Serbian army in the region viewed its role as protecting local Orthodox Christian communities and avenging the medieval battle of Kosovo, though it forced Catholic Albanians to convert to Orthodox Christianity.

Question: Question: How old was Wight when Smith died? Passage:Lyman Wight (May 9, 1796 March 31, 1858) was an early leader in the Latter Day Saint movement. He was the leader of the Latter Day Saints in Daviess County, Missouri, in 1838. In 1841, he was ordained a member of the Quorum of the Twelve Apostles. After the death of Joseph Smith resulted in a succession crisis, Wight led his own break-off group of Latter Day Saints to Texas, where they created a settlement. While in Texas, Wight broke with the main body of the group led by Brigham Young. Wight was ordained president of his own church, but he later sided with the claims of William Smith, and eventually of Joseph Smith III. After his death, most of the "Wightites" (as members of this church were called) joined with the Reorganized Church of Jesus Christ of Latter Day Saints.

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" (), 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.
