Context: Old East Slavic, "Old Russian, Old Rusian" was a language used in the 10th15th centuries by East Slavs in Kievan Rus' and states which evolved after the collapse of Kievan Rus'. Dialects of it were spoken, though not exclusively, in the area today occupied by Belarus, central and northern Ukraine, and parts of western Russia., The Black Sea is a body of water between Eastern Europe and Western Asia, bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. It is supplied by a number of major rivers, such as the Danube, Dnieper, Rioni, Southern Bug, and Dniester. The Black Sea has an area of (not including the Sea of Azov), a maximum depth of , and a volume of . It is constrained by the Pontic Mountains to the south and by the Caucasus Mountains to the east, and features a wide shelf to the northwest. The longest east-west extent is about ., Perekop  is an urban-type settlement located on the Perekop Isthmus connecting the Crimean peninsula to the Ukrainian mainland. It is known for the Fortress Or Qapi that served as the gateway to Crimea. The village currently is part of Armyansk Municipality. Population: , Kerch (, Old East Slavic: , , , Ancient Greek: "Pantikapaion") is a city of regional significance on the Kerch Peninsula in the east of the Crimea.
Population: , Kuban is a geographic region of Southern Russia surrounding the Kuban River, on the Black Sea between the Don Steppe, the Volga Delta and the Caucasus, and separated from the Crimean Peninsula to the west by the Kerch Strait. Krasnodar Krai is often referred to as "Kuban", both officially and unofficially, although the term is not exclusive to the krai and accommodates the republics of Adygea, KarachayCherkessia, and parts of Stavropol Krai., Pontic Greek is a Greek language originally spoken in the Pontus area on the southern shores of the Black Sea, northeastern Anatolia, the Eastern Turkish/Caucasus province of Kars, southern Georgia and today mainly in northern Greece. The linguistic lineage of Pontic Greek stems from Ionic Greek via Koine and Byzantine Greek and contains influences from Georgian, Russian, Turkish and to a lesser extent, Persian (via Ottoman Turkish) and various Caucasian languages. Its Ophitic variant has been identified as the living language that is closest to Ancient Greek. Its speakers are referred to as Pontic Greeks or Pontian Greeks., Tmutarakan or Tmutorakan was the name of a Mediaeval Kievan Rus' principality and trading town that controlled the Cimmerian Bosporus, the passage from the Black Sea to the Sea of Azov. Its site was the ancient Greek colony of Hermonassa, situated on the Taman peninsula, in the present-day Krasnodar Krai of Russia, roughly opposite Kerch. The Khazar fortress of Tamantarkhan (from which the Byzantine name for the city, Tamatarcha, is derived) was built on the site in the 7th century and became known as Tmutarakan when it came under Kievan Rus control in the 10th and 11th centuries., The Crimean Peninsula ("Krymskiy poluostrov;" , "Kryms'ky pivostriv"), also known simply as Crimea ( "Krym" "Krym"), is a major land mass on the northern coast of the Black Sea that is almost completely surrounded by both the Black Sea and the smaller Sea of Azov to the northeast. The peninsula is located south of the Ukrainian region of Kherson and west of the Russian region of Kuban. It is connected to Kherson Oblast by the Isthmus of Perekop and is separated from Kuban by the Strait of Kerch. The Arabat Spit is located to the northeast, a narrow strip of land that separates a system of lagoons named Sivash from the Sea of Azov., Tuzla Island ( Ukrainian :  ; Russian :  ; Crimean Tatar : Tuzla ) ( from Turkish `` tuzluk '' - saturated solution of salt in water for salting fish ) - is a sandy islet in the form of a spit located in the middle of the Strait of Kerch between the Kerch Peninsula in the west and the Taman Peninsula in the east . Administratively , it is part of Kerch city in eastern Crimea ., The Taman Peninsula ("Tamanskiy poluostrov"), a peninsula in the present-day Krasnodar Krai of Russia, borders on the north with the Sea of Azov, on the west with the Strait of Kerch and on the south with the Black Sea. The area has evolved over the past two millennia from a chain of islands into today's peninsula. In ancient times the Pontic Greek colonies of Hermonassa and Phanagoria stood on the peninsula, as did the later city of Tmutarakan., Old French (', ', ""; Modern French ) was the Gallo-Romance dialect continuum spoken from the 9th century to the 14th century. 
In the 14th century, these dialects came to be collectively known as the "langues d'oïl", contrasting with the "langue d'oc" or Occitan language in the south of France. The mid-14th century is taken as the transitional period to Middle French, the language of the French Renaissance, specifically based on the dialect of the Île-de-France region., Ancient Greek includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD. It is often roughly divided into the Archaic period (9th to 6th centuries BC), Classical period (5th and 4th centuries BC), and Hellenistic period (3rd century BC to the 6th century AD). It is antedated in the second millennium BC by Mycenaean Greek., The Sea of Azov ("Azovs'ke more/Azovke more") is a sea in Eastern Europe. To the south it is linked by the narrow (about ) Strait of Kerch to the Black Sea, and it is sometimes regarded as a northern extension of the Black Sea. The sea is bounded in the north by mainland Ukraine, in the east by Russia, and in the west by the Crimean Peninsula. The Don and Kuban are the major rivers that flow into it. The Sea of Azov is the shallowest sea in the world, with the depth varying between . There is a constant outflow of water from the Sea of Azov to the Black Sea., An islet is a very small island. Types. As suggested by its origin as "islette", an Old French diminutive of "isle", use of the term implies small size, but little attention is given to drawing an upper limit on its applicability., Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara., Phanagoria was the largest ancient Greek city on the Taman peninsula, spread over two plateaus along the eastern shore of the Cimmerian Bosporus.
The city was a large emporium for all the traffic between the coast of the Maeotian marshes and the countries on the southern side of the Caucasus. It was the eastern capital of the Bosporan Kingdom, with Panticapaeum being the western capital. Strabo described it as a noteworthy city which was renowned for its trade. Shortly a Catholic Metropolitan Archdiocese while a medieval Genosese colony under the name Matrega, it remains a Latin Catholic titular see.
Today the site is located at a short distance to the west of Sennoy in Krasnodar Krai, Russia. Another ancient Greek city, Hermonassa, lies to the west, on the shoreline of modern Taman., Kherson Oblast (translit. "Khersonska oblast"; also referred to as Khersonshchyna  "") is an oblast (province) in southern Ukraine, just north of Crimea. Its administrative center is Kherson. The area of the region is 28,461 km², its population (as of 1 January 2012) is 1,083,367., The Kerch Peninsula is a major and prominent geographic peninsula located at the eastern end of the Crimean Peninsula., An island or isle is any piece of sub-continental land that is surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, e.g. the Philippines., The Isthmus of Perekop (translit. "Perekops'kyy pereshyyok" translit. "Perekopskiy peresheek" ) is the narrow, wide strip of land that connects the Crimean Peninsula to the mainland of Ukraine. The isthmus is located between the Black Sea to the west and the Sivash to the east. The isthmus takes its name from the Tatar fortress of Perekop., Krasnodar Krai is a federal subject of Russia (a krai), located in the Southern Federal District.

Context: , under current sponsorship as , is a multi-purpose stadium in Hiroshima, Japan. It is the home ground of J. League club Sanfrecce Hiroshima. It has a capacity of 36,906. It is an all-seater. It was formerly known as Hiroshima Park Main Stadium., Hiroshima is perhaps best known as the first city in history to be targeted by a nuclear weapon when the United States Army Air Forces (USAAF) dropped an atomic bomb on the city (and later on Nagasaki) at 8:15 a.m. on August 6, 1945, near the end of World War II., World War II (often abbreviated to WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the world's nationsincluding all of the great powerseventually forming two opposing military alliances: the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. In a state of "total war", the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, erasing the distinction between civilian and military resources. Marked by mass deaths of civilians, including the Holocaust (in which approximately 11 million people were killed) and the strategic bombing of industrial and population centres (in which approximately one million were killed, and which included the atomic bombings of Hiroshima and Nagasaki), it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history., The United States Army Air Forces (USAAF or AAF) was the military aviation service of the United States of America during and immediately after World War II, successor to the United States Army Air Corps and the direct predecessor of the United States Air Force. The AAF were a component of the United States Army, which in 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Army Chief of Staff., , also known as the , is a rubber-tired transit system operated by Hiroshima Rapid Transit in Hiroshima, Japan. Astram opened August 8, 1994 for the 1994 Asian Games in Hiroshima. The line connects between central Hiroshima and Hiroshima Big Arch, which was the main stadium of the Asian Games. On March 14, 2015, a new station, Shin-Hakushima, opened to make a new connection between the Astram Line and JR lines. An extension west to Nishi-Hiroshima Station is currently being planned., World War I (WWI or WW1), also known as the First World War, or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved., The Asian Games, also known as Asiad, is a Pancontinental multi-sport event held every four years among athletes from all over Asia. The Games were regulated by the Asian Games Federation (AGF) from the first Games in New Delhi, India, until the 1978 Games. Since the 1982 Games they have been organized by the Olympic Council of Asia (OCA), after the breakup of the Asian Games Federation. The Games are recognized by the International Olympic Committee (IOC) and are described as the second largest multi-sport event after the Olympic Games., Kamiyasu Station is a HRT station on Astram Line , located in 2 - 30 - 10 , Kamiyasu , Asaminami - ku , Hiroshima ., The 1994 Asian Games also known as XII Asiad were held from October 2 to October 16, 1994, in Hiroshima, Japan. The main theme of this edition was to promote peace and harmony among Asian nations. It was emphasized by the host because the venue was the site of the first atomic bomb attack 49 years earlier. Due to the 1991 Gulf War, Iraq was suspended from the games., During World War II, the American atomic bombings of Hiroshima and Nagasaki made Nagasaki the second and, to date, last city in the world to experience a nuclear attack., Subject: kamiyasu station, Relation: country, Options: (A) india (B) japan (C) united states (D) united states of america (E) world

Context: A carbohydrate is a biological molecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogenoxygen atom ratio of 2:1 (as in water); in other words, with the empirical formula (where "m" could be different from "n"). Some exceptions exist; for example, deoxyribose, a sugar component of DNA, has the empirical formula CHO. Carbohydrates are technically hydrates of carbon; structurally it is more accurate to view them as polyhydroxy aldehydes and ketones., Fructose, or fruit sugar, is a simple ketonic monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed directly into the bloodstream during digestion. Fructose was discovered by French chemist Augustin-Pierre Dubrunfaut in 1847. The name "fructose" was coined in 1857 by the English chemist William Miller. Pure, dry fructose is a very sweet, white, odorless, crystalline solid and is the most water-soluble of all the sugars.
Fructose is found in honey, tree and vine fruits, flowers, berries, and most root vegetables., Sucrose is a common, naturally occurring saccharide found in many plants and plant parts. Saccharose is an obsolete name for sugars in general, especially sucrose. The molecule is a disaccharide combination of the monosaccharides glucose and fructose with the formula CHO., 1,3,5-triazine, also called s-triazine, is an organic chemical compound with the formula (HCN). It is a six-membered heterocyclic aromatic ring, one of several isomeric triazines. S-triazine and its derivatives are useful in a variety of applications. , Ammelide ( 6 - Amino - 2,4 - Dihydroxy - 1,3,5 - Triazine ) is a triazine and the hydrolysis product of ammeline ., Ammeline (4,6-diamino-2-hydroxy-1,3,5-triazine) is a triazine derivative. It is the hydrolysis product of melamine., Glucose is a simple sugar with the molecular formula CHO. Glucose circulates in the blood of animals as blood sugar. It is made during photosynthesis from water and carbon dioxide, using energy from sunlight. The reverse of the photosynthesis reaction, which releases this energy, is an important source of power for cellular respiration. Glucose is stored as a polymer, in plants as starch and in animals as glycogen, for times when the organism will need it., Hydrolysis usually means the cleavage of chemical bonds by the addition of water. When a carbohydrate is broken into its component sugar molecules by hydrolysis (e.g. sucrose being broken down into glucose and fructose), this is termed saccharification. Generally, hydrolysis or saccharification is a step in the degradation of a substance., A triazine is class of nitrogen-containing heterocycles. The parent molecules' molecular formula is . They exist in three isomeric forms, 1,3,5-triazines being common., Melamine is an organic base and a trimer of cyanamide, with a 1,3,5-triazine skeleton. Like cyanamide, it contains 67% nitrogen by mass and, if mixed with resins, has fire retardant properties due to its release of nitrogen gas when burned or charred, and has several other industrial uses. Melamine is also a metabolite of cyromazine, a pesticide. It is formed in the body of mammals that have ingested cyromazine. It has been reported that cyromazine can also be converted to melamine in plants., Subject: ammelide, Relation: instance_of, Options: (A) 1 (B) addition (C) base (D) chemical (E) chemical compound (F) component (G) degradation (H) dna (I) fruit (J) gas (K) hydrogen (L) metabolite (M) molecular formula (N) molecule (O) name (P) organism (Q) plant (R) product (S) ratio (T) release (U) skeleton (V) sugars (W) three (X) triazine (Y) variety (Z) water
