Catalan evolved from Vulgar Latin around the eastern Pyrenees in the 9th century. During the Low Middle Ages it saw a golden age as the literary and dominant language of the Crown of Aragon, and was widely used all over the Mediterranean. The union of Aragon with the other territories of Spain in 1479 marked the start of the decline of the language. In 1659 Spain ceded Northern Catalonia to France, and Catalan was banned in both states in the early 18th century. 19th-century Spain saw a Catalan literary revival, which culminated in the 1913 orthographic standardization, and the officialization of the language during the Second Spanish Republic (1931–39). However, the Francoist dictatorship (1939–75) banned the language again.
What year started the decline of Catalan as a main language?
1479


Input: Bird migration
Records of bird migration were made as much as 3,000 years ago by the Ancient Greek writers Hesiod, Homer, Herodotus and Aristotle. The Bible also notes migrations, as in the Book of Job (39:26), where the inquiry is made: "Is it by your insight that the hawk hovers, spreads its wings southward?" The author of Jeremiah (8:7) wrote: "Even the stork in the heavens knows its seasons, and the turtle dove, the swift and the crane keep the time of their arrival."

Who recorded early records of migration?
Output: Ancient Greek writers


Input: Article: The North Korean contributions to the Chinese Communist victory were not forgotten after the creation of the People's Republic of China in 1949. As a token of gratitude, between 50,000 and 70,000 Korean veterans that served in the PLA were sent back along with their weapons, and they later played a significant role in the initial invasion of South Korea. China promised to support the North Koreans in the event of a war against South Korea. The Chinese support created a deep division between the Korean Communists, and Kim Il-sung's authority within the Communist party was challenged by the Chinese faction led by Pak Il-yu, who was later purged by Kim.

Now answer this question: Who did China pledge to support if a conflict should occur between North and South Korea?

Output: the North Koreans


Article: Detroit's protracted decline has resulted in severe urban decay and thousands of empty buildings around the city. Some parts of Detroit are so sparsely populated that the city has difficulty providing municipal services. The city has considered various solutions, such as demolishing abandoned homes and buildings; removing street lighting from large portions of the city; and encouraging the small population in certain areas to move to more populated locations. While some have estimated 20,000 stray dogs roam the city, studies have shown the true number to be around 1,000-3,000. Roughly half of the owners of Detroit's 305,000 properties failed to pay their 2011 tax bills, resulting in about $246 million in taxes and fees going uncollected, nearly half of which was due to Detroit; the rest of the money would have been earmarked for Wayne County, Detroit Public Schools, and the library system.

Question: How much in unpaid taxes did Detroit fail to collect in 2011?
Ans: $246 million


Here is a question about this article: The Dominican Order was affected by a number of elemental influences. Its early members imbued the order with a mysticism and learning. The Europeans of the order embraced ecstatic mysticism on a grand scale and looked to a union with the Creator. The English Dominicans looked for this complete unity as well, but were not so focused on ecstatic experiences. Instead, their goal was to emulate the moral life of Christ more completely. The Dartford nuns were surrounded by all of these legacies, and used them to create something unique. Though they are not called mystics, they are known for their piety toward God and their determination to live lives devoted to, and in emulation of, Him.
What is the answer to this question: What group of nuns are used all aspects of the Dominican Order for their work? 
****
So... Dartford


Article: On 13 December 1904, Hungarian Sándor Just and Croatian Franjo Hanaman were granted a Hungarian patent (No. 34541) for a tungsten filament lamp that lasted longer and gave brighter light than the carbon filament. Tungsten filament lamps were first marketed by the Hungarian company Tungsram in 1904. This type is often called Tungsram-bulbs in many European countries. Filling a bulb with an inert gas such as argon or nitrogen retards the evaporation of the tungsten filament compared to operating it in a vacuum. This allows for greater temperatures and therefore greater efficacy with less reduction in filament life.

Question: Which company first marketed the tungsten filament lamp?
Ans:
Tungsram
