In this task, you are given a context, a subject, a relation, and many options. Based on the context, from the options select the object entity that has the given relation with the subject. Answer with text (not indexes).

Example Input: Context: Species richness is the number of different species represented in an ecological community, landscape or region. Species richness is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions. Species diversity takes into account both species richness and species evenness., Sufflamen bursa , also known as the Bursa , Scythe or Boomerang Triggerfish , is a Triggerfish from the Indo - Pacific . It occasionally makes its way into the aquarium trade . It grows to a size of 25 cm in length . `` Scythe '' markings on the tail of the triggerfish contain pigments which may change hue from light yellow to dark brown depending on mood of the fish ., Triggerfishes are about 40 species of often brightly colored fish of the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the aptly named oceanic triggerfish ("Canthidermis maculata"), are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered., Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons which support and protect the coral polyps. Most reefs grow best in warm, shallow, clear, sunny and agitated waters., Subject: sufflamen bursa, Relation: taxon_rank, Options: (A) group (B) species
Example Output: species

Example Input: Context: In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, trivial name, trivial epithet, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; this kind of name is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is by no means always the case., Verdigris is the common name for a green pigment obtained through the application of acetic acid to copper plates or the natural patina formed when copper, brass or bronze is weathered and exposed to air or seawater over a period of time. It is usually a basic copper carbonate, but near the sea will be a basic copper chloride. If acetic acid is present at the time of weathering, it may consist of copper(II) acetate., In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs., Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. Australia's capital is Canberra, and its largest urban area is Sydney., Green is the color between blue and yellow on the spectrum of visible light. It is evoked by light with a predominant wavelength of roughly 495570 nm. In the subtractive color system, used in painting and color printing, it is created by a combination of yellow and blue, or yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors.
The modern English word green comes from the Middle English and Anglo-Saxon word "grene", from the same Germanic root as the words "grass" and "grow". It is the color of living grass and leaves and as a result is the color most associated with springtime, growth and nature. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content.
In surveys made in Europe and the United States, green is the color most commonly associated with nature, life, health, youth, spring, hope and envy. In Europe and the U.S. green is sometimes associated with death (green has several seemingly contrary associations), sickness, or the devil, but in China its associations are very positive, as the symbol of fertility and happiness. In the Middle Ages and Renaissance, when the color of clothing showed the owner's social status, green was worn by merchants, bankers and the gentry, while red was the color of the nobility. The "Mona Lisa" by Leonardo da Vinci wears green, showing she is not from a noble family; the benches in the British House of Commons are green, while those in the House of Lords are red. Green is also the traditional color of safety and permission; a green light means go ahead, a green card permits permanent residence in the United States. It is the most important color in Islam. It was the color of the banner of Muhammad, and is found in the flags of nearly all Islamic countries, and represents the lush vegetation of Paradise. It is also often associated with the culture of Gaelic Ireland, and is a color of the flag of Ireland. Because of its association with nature, it is the color of the environmental movement. Political groups advocating environmental protection and social justice describe themselves as part of the Green movement, some naming themselves Green parties. This has led to similar campaigns in advertising, as companies have sold green, or environmentally friendly, products., The genus Stropharia ( sometimes known by the common name roundheads ) is a group of medium to large agarics with a distinct membranous ring on the stipe . Well - known members of this genus include the edible Stropharia rugosoannulata and the blue - green verdigris agarics ( Stropharia aeruginosa and allies ) . Stropharia are not generally regarded as good to eat and there are doubts over the edibility of several species . However the species Stropharia rugosoannulata is regarded as exquisitely edible when young , is now the premier mushroom for outdoor bed culture by mycophiles in temperate climates ., Stropharia rugosoannulata, commonly known as the wine cap stropharia, "garden giant", burgundy mushroom or king stropharia (Japanese: "saketsubatake"), is an agaric of the family Strophariaceae found in Europe and North America, and introduced to Australia and New Zealand., New Zealand is an island nation in the southwestern Pacific Ocean. The country geographically comprises two main landmassesthat of the North Island, or Te Ika-a-Mui, and the South Island, or Te Waipounamuand numerous smaller islands. New Zealand is situated some east of Australia across the Tasman Sea and roughly south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long period of isolation, New Zealand developed a distinct biodiversity of animal, fungal and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington, while its most populous city is Auckland., Woodland is a low-density forest forming open habitats with plenty of sunlight and limited shade. Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are referred to as forests. , An agaric or is a type of mushroom fungus fruiting body characterized by the presence of a pileus (cap) that is clearly differentiated from the stipe (stalk), with lamellae (gills) on the underside of the pileus. "Agaric" can also refer to a basidiomycete species characterized by an agaric-type fruiting body. Archaically agaric meant 'tree-fungus' (after Latin "agaricum"); however, that changed with the Linnaean interpretation in 1753 when Linnaeus used the generic name "Agaricus" for gilled mushrooms., Stropharia aeruginosa, commonly known as the verdigris agaric, is a medium-sized green, slimy woodland mushroom, found on lawns, mulch and woodland from spring to autumn. The edibility of this mushroom is controversial - some sources claim that it is edible, while others claim it to be poisonous, although effects are little known and its toxic constituents undescribed., The Strophariaceae are a family of fungi in the order Agaricales. Under an older classification, the family covered 18 genera and 1316 species. The species of Strophariaceae have red-brown to dark brown spore prints, while the spores themselves are smooth and have an apical germ pore. These agarics are also characterized by having a cutis-type pileipellis. Ecologically, all species in this group are saprotrophs, growing on various kinds of decaying organic matter. The family was circumscribed in 1946 by mycologists Rolf Singer and Alexander H. Smith., Subject: stropharia, Relation: parent_taxon, Options: (A) agaricus (B) animal (C) area (D) areas (E) leonardo (F) plant (G) stropharia (H) strophariaceae
Example Output: strophariaceae

Example Input: Context: 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., Saint Petersburg is Russia's second-largest city after Moscow, with five million inhabitants in 2012, and an important Russian port on the Baltic Sea. It is politically incorporated as a federal subject (a federal city). Situated on the Neva River, at the head of the Gulf of Finland on the Baltic Sea, it was founded by Tsar Peter the Great on May . In 1914, the name was changed from Saint Petersburg to Petrograd, in 1924 to Leningrad, and in 1991 back to Saint Petersburg. Between 17131728 and 17321918, Saint Petersburg was the imperial capital of Russia. In 1918, the central government bodies moved to Moscow., Helsinki  is the capital and largest city of Finland. It is in the region of Uusimaa, in southern Finland, on the shore of the Gulf of Finland. Helsinki has a population of , an urban population of 1,214,210, and a metropolitan population of over 1.4 million, making it the most populous municipality and urban area in Finland. Helsinki is located some north of Tallinn, Estonia, east of Stockholm, Sweden, and west of Saint Petersburg, Russia. Helsinki has close historical connections with these three cities., Mäntyniemi ("Talludden" in Swedish) is one of the three official residences of the President of Finland besides the Presidential Palace and Kultaranta. Mäntyniemi was finished in 1993. Four Finnish presidents have lived there: Mauno Koivisto, Martti Ahtisaari, Tarja Halonen, and the incumbent Sauli Niinistö., Finland , officially the Republic of Finland, is a sovereign state in Northern Europe. A peninsula with the Gulf of Finland to the south and the Gulf of Bothnia to the west, the country has land borders with Sweden to the northwest, Norway to the north, and Russia to the east. Estonia is south of the country across the Gulf of Finland. Finland is a Nordic country situated in the geographical region of Fennoscandia, which also includes Scandinavia. Finland's population is 5.5 million (2014), staying roughly on the same level over the past two decades. The majority of the population is concentrated in the southern region. In terms of area, it is the eighth largest country in Europe and the most sparsely populated country in the European Union., A constitution is a set of fundamental principles or established precedents according to which a state or other organization is governed. These rules together make up, i.e. "constitute", what the entity is. When these principles are written down into a single document or set of legal documents, those documents may be said to embody a "written" constitution; if they are written down in a single comprehensive document, it is said to embody a "codified" constitution. Some constitutions (such as the constitution of the United Kingdom) are uncodified, but written in numerous fundamental Acts of a legislature, court cases or treaties., Tallinn (or ) is the capital and largest city of Estonia. It is situated on the northern coast of the country, on the shore of the Gulf of Finland, south of Helsinki, east of Stockholm and west of Saint Petersburg. From the 13th century until 1918 (and briefly during the Nazi occupation of Estonia from 1941 to 1944), the city was known as Reval. Tallinn occupies an area of and has a population of 443,894. Approximately 32% of Estonia's total population lives in Tallinn., Stockholm (or ) is the capital of Sweden and the most populous city in the Nordic countries; 932,917 people live in the municipality, approximately 1.5 million in the urban area, and 2.3 million in the metropolitan area. The city is spread across 14 islands on the coast in the southeast of Sweden at the mouth of Lake Mälaren, by the Stockholm archipelago and the Baltic Sea. The area has been settled since the Stone Age, in the 6th millennium BC, and was founded as a city in 1252 by a Swedish statesman Birger Jarl. It is also the capital of Stockholm County., A head of state (or chief of state) is the public persona that officially represents the national unity and legitimacy of a sovereign state. In developing the current Constitution of France (1958), former French president Charles de Gaulle said the head of state should embody "the spirit of the nation" (""). In some countries, typically those with parliamentary governments, the head of state is a ceremonial figurehead that does not actually guide day-to-day government activities and may not even be empowered to exercise any kind of political authority (e.g., Queen Elizabeth II in the United Kingdom). In other countries, the head of state is also the head of government, such as in the U.S., where the president is both a public figurehead and the actual highest ranking political leader who, in practice, oversees the executive branch., Urho Kaleva Kekkonen (3 September 1900  31 August 1986) was a Finnish politician who served as Prime Minister of Finland (19501953, 19541956) and later as the eighth and longest-serving President of Finland (19561982). Kekkonen continued the active neutrality policy of his predecessor President Juho Kusti Paasikivi, a doctrine that came to be known as the PaasikiviKekkonen line, under which Finland retained its independence while maintaining extensive trade with members of NATO as well as those of the Warsaw Pact., Mannerheimintie, named after the Finnish military leader and statesman Carl Gustaf Emil Mannerheim, is the most famous street in Helsinki, Finland. It was originally named Heikinkatu, after Robert Henrik Rehbinder, but was renamed after the Winter War. The change of name was also suitable due to Mannerheim having paraded in along that road during the Finnish Civil War (1918), after German forces allied with Mannerheim's Finnish forces had retaken the city. That event is also portrayed in the landmark statue of Mannerheim sitting horseback. The statue is located along the Mannerheimintie just outside the modern arts museum Kiasma., The Warsaw Pact, formally the Treaty of Friendship, Co-operation, and Mutual Assistance and sometimes, informally, WarPac. was a collective defense treaty among the Soviet Union and seven other Soviet satellite states in Central and Eastern Europe in existence during the Cold War. The Warsaw Pact was the military complement to the Council for Mutual Economic Assistance (CoMEcon), the regional economic organization for the communist states of Central and Eastern Europe. The Warsaw Pact was created in reaction to the integration of West Germany into NATO in 1955 per the London and Paris Conferences of 1954, but it is also considered to have been motivated by Soviet desires to maintain control over military forces in Central and Eastern Europe., Juho Kusti Paasikivi (27 November 1870  14 December 1956) was the seventh President of Finland (19461956). Representing the Finnish Party and the National Coalition Party, he also served as Prime Minister of Finland (1918 and 19441946), and was an influential figure in Finnish economics and politics for over fifty years. He is remembered as a main architect of Finland's foreign policy after the Second World War., Meilahti (in Swedish Mejlans) is a neighbourhood of Helsinki between Mannerheimintie (the main entrance road to Helsinki) and a bay named Seurasaarenselkä. Most of the houses in Meilahti were built in the 1930s and 1940s. Meilahti is home to over 6700 people. Meilahti is the location of Mäntyniemi, official residence of the President of Finland, as well as Kesäranta, the official residence of Prime Minister of Finland. Near Mäntyniemi is the former presidential residence, Tamminiemi, which is today a museum dedicated to president Urho Kekkonen., Kesäranta (in Swedish Villa Bjälbo) is the official residence of the Prime Minister of Finland. It is located in the Meilahti area of Helsinki, overlooking a bay on the north-west side of the city. The Finnish name Kesäranta means ""summer shore"". The residence is owned by the Finnish state through Senate Properties., The Gulf of Finland  is the easternmost arm of the Baltic Sea. It extends between Finland (to the north) and Estonia (to the south) all the way to Saint Petersburg in Russia, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbours are located farthest in, near Saint Petersburg (including Primorsk). As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf., Tamminiemi ( Villa Ekudden in Swedish ) , is a villa located in the Meilahti district of Helsinki . It was one of the official residences of the President of Finland from 1940 until 1981 . From that date , until his death , it served as the residence of President Urho Kekkonen . It is now the Urho Kekkonen Museum . It is located in a park by the sea . Tamminiemi 's floor area is about 450 square metres . Designed by architects Sigurd Frosterus and Gustaf Strengell , the jugendstil villa was built in 1903 for the Danish - born businessman Jörgen Nissen . The villa was later owned or rented by a number of individuals , before being acquired by the publisher and artistic patron Amos Anderson in 1924 . Anderson donated Tamminiemi to the Finnish State in 1940 , to serve as a presidential residence . Although Presidents Ryti and Mannerheim resided at Tamminiemi , the villa is particularly associated with President Kekkonen - due in large part to the fact that it was his home for around thirty years . President Paasikivi preferred to use the Presidential Palace as his official residence during his presidency . Tamminiemi also has a famous sauna which president Kekkonen used to entertain his guests ., The President of the Republic of Finland is the nation's head of state. Under the Finnish constitution, executive power is vested in the president and the government, with the president possessing only residual powers. The president is elected directly by the people of Finland for a term of six years. Since 1991, no president may be elected for more than two consecutive terms. The president must be a native-born Finnish citizen. The office was established by the Constitution Act of 1919. The current office-holder is Sauli Niinistö., A sauna (or ), or sudatory, is a small room or building designed as a place to experience dry or wet heat sessions, or an establishment with one or more of these facilities. The steam and high heat make the bathers perspire. Saunas can be divided into two basic types: conventional saunas that warm the air or infrared saunas that warm objects. Infrared saunas may use a variety of materials in their heating area such as charcoal, active carbon fibers, and other materials., Sauli Väinämö Niinistö (born 24 August 1948) is a Finnish politician and the 12th President of Finland, in office since 2012., The Prime Minister (literally translated as Head Minister, Swedish: "statsminister", literally translated as Minister of State) is the Head of Government of Finland. The Prime Minister is appointed by the President, who is the Head of State. The current Prime Minister is Juha Sipilä of the Centre Party., Subject: tamminiemi, Relation: occupation, Options: (A) carbon (B) head of state (C) leader (D) major (E) military (F) official (G) politician (H) president (I) prime minister (J) publisher (K) saint (L) sovereign (M) soviet union (N) statesman (O) tsar (P) united kingdom
