Problem: Hydrogen gas forms explosive mixtures with air if it is 474% concentrated and with chlorine if it is 595% concentrated. The mixtures may be ignited by spark, heat or sunlight. The hydrogen autoignition temperature, the temperature of spontaneous ignition in air, is 500 C (932 F). Pure hydrogen-oxygen flames emit ultraviolet light and with high oxygen mix are nearly invisible to the naked eye, as illustrated by the faint plume of the Space Shuttle Main Engine compared to the highly visible plume of a Space Shuttle Solid Rocket Booster. The detection of a burning hydrogen leak may require a flame detector; such leaks can be very dangerous. Hydrogen flames in other conditions are blue, resembling blue natural gas flames. The destruction of the Hindenburg airship was an infamous example of hydrogen combustion; the cause is debated, but the visible orange flames were the result of a rich mixture of hydrogen to oxygen combined with carbon compounds from the airship skin.
What kind of light do hydrogen-oxygen flames make?
The answer is the following: ultraviolet light

In 1902, the Siemens company developed a tantalum lamp filament. These lamps were more efficient than even graphitized carbon filaments and could operate at higher temperatures. Since tantalum metal has a lower resistivity than carbon, the tantalum lamp filament was quite long and required multiple internal supports. The metal filament had the property of gradually shortening in use; the filaments were installed with large loops that tightened in use. This made lamps in use for several hundred hours quite fragile. Metal filaments had the property of breaking and re-welding, though this would usually decrease resistance and shorten the life of the filament. General Electric bought the rights to use tantalum filaments and produced them in the US until 1913.
In what year was the tantalum light filament invented?
1902

Input: Armenia
The exonym Armenia is attested in the Old Persian Behistun Inscription (515 BC) as Armina ( ). The ancient Greek terms (Armenia) and (Armenioi, "Armenians") are first mentioned by Hecataeus of Miletus (c. 550 BC c. 476 BC). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians. According to the histories of both Moses of Chorene and Michael Chamchian, Armenia derives from the name of Aram, a lineal descendant of Hayk.

What name did Armenia gain it's name from?
Output: Aram

Input: Article: The ancient trade route between India and Tibet that passed through Kathmandu enabled a fusion of artistic and architectural traditions from other cultures to be amalgamated with local art and architecture. The monuments of Kathmandu City have been influenced over the centuries by Hindu and Buddhist religious practices. The architectural treasure of the Kathmandu valley has been categorized under the well-known seven groups of heritage monuments and buildings. In 2006 UNESCO declared these seven groups of monuments as a World Heritage Site (WHS). The seven monuments zones cover an area of 188.95 hectares (466.9 acres), with the buffer zone extending to 239.34 hectares (591.4 acres). The Seven Monument Zones (Mzs) inscribed originally in 1979 and with a minor modification in 2006 are Durbar squares of Hanuman Dhoka, Patan and Bhaktapur, Hindu temples of Pashupatinath and Changunarayan, the Buddhist stupas of Swayambhu and Boudhanath.

Now answer this question: What religion does Changunarayan belong to?

Output: Hindu

Article: Switzerland lies between latitudes 45 and 48 N, and longitudes 5 and 11 E. It contains three basic topographical areas: the Swiss Alps to the south, the Swiss Plateau or Central Plateau, and the Jura mountains on the west. The Alps are a high mountain range running across the central-south of the country, comprising about 60% of the country's total area. The majority of the Swiss population live in the Swiss Plateau. Among the high valleys of the Swiss Alps many glaciers are found, totalling an area of 1,063 square kilometres (410 sq mi). From these originate the headwaters of several major rivers, such as the Rhine, Inn, Ticino and Rhone, which flow in the four cardinal directions into the whole of Europe. The hydrographic network includes several of the largest bodies of freshwater in Central and Western Europe, among which are included Lake Geneva (also called le Lac Leman in French), Lake Constance (known as Bodensee in German) and Lake Maggiore. Switzerland has more than 1500 lakes, and contains 6% of Europe's stock of fresh water. Lakes and glaciers cover about 6% of the national territory. The largest lake is Lake Geneva, in western Switzerland shared with France. The Rhone is both the main source and outflow of Lake Geneva. Lake Constance is the second largest Swiss lake and, like the Lake Geneva, an intermediate step by the Rhine at the border to Austria and Germany. While the Rhone flows into the Mediterranean Sea at the French Camarque region and the Rhine flows into the North Sea at Rotterdam in the Netherlands, about 1000 km apart, both springs are only about 22 km apart from each other in the Swiss Alps.

Question: How much of Switzerland's total area do the Alps comprise?
Ans: 60%

Input: Qing dynasty
The Qing emperors were generally adept at poetry and often skilled in painting, and offered their patronage to Confucian culture. The Kangxi and Qianlong Emperors, for instance, embraced Chinese traditions both to control them and to proclaim their own legitimacy. The Kangxi Emperor sponsored the Peiwen Yunfu, a rhyme dictionary published in 1711, and the Kangxi Dictionary published in 1716, which remains to this day an authoritative reference. The Qianlong Emperor sponsored the largest collection of writings in Chinese history, the Siku Quanshu, completed in 1782. Court painters made new versions of the Song masterpiece, Zhang Zeduan's Along the River During the Qingming Festival whose depiction of a prosperous and happy realm demonstrated the beneficence of the emperor. The emperors undertook tours of the south and commissioned monumental scrolls to depict the grandeur of the occasion. Imperial patronage also encouraged the industrial production of ceramics and Chinese export porcelain.

When was the Siku Quanshu finished?
Output:
1782
