Task: Question Answering
Input (English): Context: Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form is important to industry., Bronze is an alloy consisting primarily of copper, commonly with about 12% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as stiffness, ductility, or machinability., Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickeliron meteorites that were not exposed to oxygen when outside Earth's atmosphere., Zinc is a chemical element with the symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table. In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn and Mg ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning)., COMPASS is an acronym for "COMP"rehensive "ASS"embler. COMPASS is any of a family of macro assembly languages on Control Data Corporation's 3000 series, and on the 60-bit CDC 6000 series, 7600 and Cyber 70 and 170 series mainframe computers. While the architectures are very different, the macro and conditional assembly facilities are similar., Tin is a chemical element with the symbol Sn (for ) and atomic number 50, is a post-transition metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide, SnO. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4. Tin is the 49th most abundant element and has, with 10 stable isotopes, the largest number of stable isotopes in the periodic table, thanks to its magic number of protons. It has two main allotropes: at room temperature, the stable allotrope is -tin, a silvery-white, malleable metal, but at low temperatures it transforms into the less dense grey -tin, which has the diamond cubic structure. Metallic tin is not easily oxidized in air., The Western Xia, also known as the Xi Xia Empire, the Tangut Empire and to the Tangut people and the Tibetans as Minyak, was an empire which existed from 1038 to 1227 in what are now the northwestern Chinese provinces of Ningxia, Gansu, eastern Qinghai, northern Shaanxi, northeastern Xinjiang, southwest Inner Mongolia, and southernmost Outer Mongolia, measuring about 800,000 square kilometers., Silicon is a chemical element with symbol Si and atomic number 14. A hard and brittle crystalline solid with a blue-gray metallic luster, it is a tetravalent metalloid. It is a member of group 14 in the periodic table, along with carbon above it and germanium, tin, lead, and flerovium below. It is rather unreactive, though less so than germanium, and has great chemical affinity for oxygen; as such, it was first prepared and characterized in pure form only in 1823 by Jöns Jakob Berzelius., Manganese is a chemical element with symbol Mn and atomic number 25. It is not found as a free element in nature; it is often found in minerals in combination with iron. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels., Copper is a chemical element with symbol Cu (from ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement., Aluminium or aluminum (in North American English) is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal. Aluminium is the third most abundant element in the Earth's crust (after oxygen and silicon) and its most abundant metal. Aluminium makes up about 8% of the crust by mass, though it is less common in the mantle below. Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is found combined in over 270 different minerals. The chief ore of aluminium is bauxite., The Ming dynasty was the ruling dynasty of Chinathen known as the for 276 years (13681644) following the collapse of the Mongol-led Yuan dynasty. The Ming, described by some as "one of the greatest eras of orderly government and social stability in human history," was the last imperial dynasty in China ruled by ethnic Han Chinese. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng (who established the Shun dynasty, soon replaced by the Manchu-led Qing dynasty), regimes loyal to the Ming throne  collectively called the Southern Ming  survived until 1683., The Song dynasty (9601279) was an era of Chinese history that began in 960 and continued until 1279. It succeeded the Five Dynasties and Ten Kingdoms period, coincided with the Liao and Western Xia dynasties, and was followed by the Yuan dynasty. It was the first government in world history to issue banknotes or true paper money nationally and the first Chinese government to establish a permanent standing navy. This dynasty also saw the first known use of gunpowder, as well as the first discernment of true north using a compass., The Yuan dynasty, officially the Great Yuan, was the empire or ruling dynasty of China established by Kublai Khan, leader of the Mongolian Borjigin clan. Although the Mongols had ruled territories including today's North China for decades, it was not until 1271 that Kublai Khan officially proclaimed the dynasty in the traditional Chinese style, and the conquest was not complete until 1279. His realm was, by this point, isolated from the other khanates and controlled most of present-day China and its surrounding areas, including modern Mongolia. It was the first foreign dynasty to rule all of China and lasted until 1368, after which its Genghisid rulers returned to their Mongolian homeland and continued to rule the Northern Yuan dynasty. Some of the Mongolian Emperors of the Yuan mastered the Chinese language, while others only used their native language (i.e. Mongolian) and the 'Phags-pa script., The Han dynasty was the second imperial dynasty of China (206 BC220 AD), preceded by the Qin dynasty (221206 BC) and succeeded by the Three Kingdoms period (220280 AD). Spanning over four centuries, the Han period is considered a golden age in Chinese history. To this day, China's majority ethnic group refers to itself as the "Han people" and the Chinese script is referred to as "Han characters".
It was founded by the rebel leader Liu Bang, known posthumously as Emperor Gaozu of Han, and briefly interrupted by the Xin dynasty (923 AD) of the former regent Wang Mang. This interregnum separates the Han dynasty into two periods: the Western Han or Former Han (206 BC  9 AD) and the Eastern Han or Later Han (25220 AD)., Yi Xing (683727), born Zhang Sui, was a Chinese astronomer, mathematician, mechanical engineer and Buddhist monk of the Tang dynasty (618907). His astronomical celestial globe featured a clockwork escapement mechanism, the first in a long tradition of Chinese astronomical clockworks., Chang'an is an ancient capital of more than ten dynasties in Chinese history, today known as Xi'an. Chang'an means "Perpetual Peace" in Classical Chinese. During the short-lived Xin dynasty, the city was renamed "Constant Peace"; yet after its fall in AD 23, the old name was restored. By the time of the Ming dynasty, the name was again changed to Xi'an, meaning "Western Peace", which has remained its name to the present day., Liang Lingzan ( simplified Chinese :  ; traditional Chinese :  ; pinyin : Liáng Lìngzàn ; Wade -- Giles : Liang Ling - Tsan ) was a Tang Dynasty military engineer and government official of the Kaiyuan era . He invented a mechanized water clock with the Tantric monk and mathematician Yi Xing ( Chinese :  ; pinyin : Y Xíng ; Wade -- Giles : I - Hsing ) . It was actually an astronomical instrument that served as a clock , made of bronze in the capital of Chang'an in the 720s . It was described by a contemporary text this way : ( It ) was made in the image of the round heavens and on it were shown the lunar mansions in their order , the equator and the degrees of the heavenly circumference . Water , flowing into scoops , turned a wheel automatically , rotating it one complete revolution in one day and night . Besides this , there were two rings fitted around the celestial sphere outside , having the sun and moon threaded on them , and these were made to move in circling orbit ... And they made a wooden casing the surface of which represented the horizon , since the instrument was half sunk in it . It permitted the exact determinations of the time of dawns and dusks , full and new moons , tarrying and hurrying . Moreover , there were two wooden jacks standing on the horizon surface , having one a bell and the other a drum in front of it , the bell being struck automatically to indicate the hours , and the drum being beaten automatically to indicate the quarters . All these motions were brought about by machinery within the casing , each depending on wheels and shafts , hooks , pins and interlocking rods , stopping devices and locks checking mutually . In addition to being an engineer and official , Lingzan was also a scholar and artist . He wrote The Five - Planet and Twenty - eight Constellation Deities ( Chinese :  ; pinyin : wxng èrshíbxiù shénxíng ) , of which a Song Dynasty copy resides in the collection of the Osaka City Art Museum ., The Tang dynasty was an imperial dynasty of China preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. It is generally regarded as a high point in Chinese civilization, and a golden age of cosmopolitan culture. Its territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty, and the Tang capital at Chang'an (present-day Xi'an) was the most populous city in the world., The Xin dynasty was a Chinese dynasty (termed so despite having only one emperor) which lasted from 9 to 23 AD. It interrupted the Han dynasty, dividing it into the periods of the Western Han and the Eastern Han., Phosphorus is a chemical element with symbol P and atomic number 15. As an element, phosphorus exists in two major formswhite phosphorus and red phosphorusbut because it is highly reactive, phosphorus is never found as a free element on Earth. At 0.099%, phosphorus is the most abundant pnictogen in the Earth's crust. With few exceptions, minerals containing phosphorus are in the maximally oxidised state as inorganic phosphate rocks., Subject: liang lingzan, Relation: date_of_birth, Options: (A) 1038 (B) 12 (C) 1227 (D) 1271 (E) 1368 (F) 14 (G) 15 (H) 1683 (I) 206 (J) 220 (K) 221 (L) 23 (M) 25 (N) 276 (O) 28 (P) 280 (Q) 29 (R) 30 (S) 33 (T) 4 (U) 50 (V) 60 (W) 683 (X) 70 (Y) 727 (Z) 8 ([) 800 (\) 960
