TASK DEFINITION: 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).
PROBLEM: Context: Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus., A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus., Labroides is a genus of wrasses native to the Indian and Pacific Oceans . This genus is collectively known as cleaner wrasses and its species are cleaner fish ., Skin is the soft outer covering of vertebrates. Other animal coverings, such as the arthropod exoskeleton have different developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin "cutis", skin). In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue, and guards the underlying muscles, bones, ligaments and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. All mammals have some hair on their skin, even marine mammals like whales, dolphins, and porpoises which appear to be hairless.
The skin interfaces with the environment and is the first line of defense from external factors. For example, the skin plays a key role in protecting the body against pathogens and excessive water loss. Its other functions are insulation, temperature regulation, sensation, and the production of vitamin D folates. Severely damaged skin may heal by forming scar tissue. This is sometimes discoloured and depigmented. The thickness of skin also varies from location to location on an organism. In humans for example, the skin located under the eyes and around the eyelids is the thinnest skin in the body at 0.5 mm thick, and is one of the first areas to show signs of aging such as "crows feet" and wrinkles. The skin on the palms and the soles of the feet is 4 mm thick and the back is 14 mm thick and is the thickest skin in the body. The speed and quality of wound healing in skin is promoted by the reception of estrogen., 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., Cleaner shrimp is a common name for a number of swimming decapod crustaceans that clean other organisms of parasites. They belong to any of three families, Hippolytidae (including the Pacific cleaner shrimp, "Lysmata amboinensis"), Palaemonidae (including the spotted "Periclimenes magnificus") and Stenopodidae (including the banded coral shrimp, "Stenopus hispidus") . The last of these families is more closely related to lobsters and crabs than it is to the remaining families. The term "cleaner shrimp" is sometimes used more specifically for the family Hippolytidae and the genus "Lysmata"., Cichlids are fish from the family Cichlidae in the order Perciformes. Cichlids are members of a suborder known as Labroidei, along with the wrasses (Labridae), damselfishes (Pomacentridae), and surfperches (Embiotocidae). This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Cichlids are popular freshwater fish kept in the home aquarium., Cleaner fish are fish that provide a service to other fish species by removing dead skin and ectoparasites. This cleaning symbiosis is an example of mutualism, an ecological interaction that benefits both parties involved. However, the cleaner fish may sometimes cheat and consume mucus or tissue, thus creating a form of parasitism. A wide variety of fish including wrasse, cichlids, catfish, pipefish, and gobies display cleaning behaviors. Similar behavior is found in other groups of animals, such as cleaner shrimps., Pipefishes or pipe-fishes (Syngnathinae) are a subfamily of small fishes, which, together with the seahorses and seadragons, form the family Syngnathidae., The wrasses are a family, Labridae, of marine fish, many of which are brightly colored. The family is large and diverse, with over 600 species in 82 genera, which are divided into 9 subgroups or tribes.
They are typically small fish, most of them less than long, although the largest, the humphead wrasse, can measure up to . They are efficient carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, picking up invertebrates disturbed by their passing. Juveniles of some representatives of the genera "Bodianus", "Epibulus","Cirrhilabrus", "Oxycheilinus", and "Paracheilinus" hide among the tentacles of the free-living mushroom coral "Heliofungia actiniformis"., In biology/ecology, parasitism is a non-mutual relationship between species, where one species, the parasite, benefits at the expense of the other, the host. Traditionally "parasite" (in biological usage) referred primarily to organisms visible to the naked eye, or macroparasites (such as helminths). Parasites can be microparasites, which are typically smaller, such as protozoa, viruses, and bacteria. Examples of parasites include the plants mistletoe and cuscuta, and animals such as hookworms., A fish is any member of a group of organisms that consist of all gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered obsolete or paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term "fish" is defined negatively as a paraphyletic group, it is not considered a formal taxonomic grouping in systematic biology. The traditional term pisces (also ichthyes) is considered a typological, but not a phylogenetic classification., Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia and the Piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, "Vandellia cirrhosa". There are armour-plated types and there are also naked types, neither having scales. Despite their name, not all catfish have prominent barbel. Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus "Corydoras", are important in the aquarium hobby. Many catfish are nocturnal, but others (many "Auchenipteridae") are "crepuscular" or "diurnal" (most "Loricariidae or" "Callichthyidae" for example)., Subject: labroides, Relation: parent_taxon, Options: (A) animal (B) areas (C) cichlidae (D) corydoras (E) cuscuta (F) embiotocidae (G) hagfish (H) hippolytidae (I) homo (J) labridae (K) labroidei (L) lysmata (M) olfactores (N) palaemonidae (O) perciformes (P) pipefish (Q) plant (R) pomacentridae (S) protozoa (T) siluriformes (U) stenopodidae (V) stenopus (W) syngnathidae (X) vandellia

PROBLEM: Context: Monica Vitti (born 3 November 1931) is an Italian actress best known for her starring roles in films directed by Michelangelo Antonioni during the early 1960s. After working with Antonioni, Vitti changed focus and began making comedies, working with director Mario Monicelli on many films. She has appeared opposite Marcello Mastroianni, Richard Harris, Terence Stamp, Michael Caine and Dirk Bogarde. Vitti won five David di Donatello Awards for Best Actress, seven Italian Golden Globes for Best Actress, the Career Golden Globe, and the Venice Film Festival Career Golden Lion Award., Rome is a city and special "comune" (named "Roma Capitale") in Italy. Rome is the capital of Italy and of the Lazio region. With 2,870,336 residents in , it is also the country's largest and most populated "comune" and fourth-most populous city in the European Union by population within city limits. The Metropolitan City of Rome has a population of 4.3 million residents. The city is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of Tiber river. The Vatican City is an independent country geographically located within the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states. , A screenplay writer, screenwriter for short, scriptwriter or scenarist is a writer who practices the craft of screenwriting, writing screenplays on which mass media such as films, television programs, comics or video games are based., MILAN ("milan(e)" is French for kite) is a European anti-tank guided missile. Design of the MILAN started in 1962, it was ready for trials in 1971, and was accepted for service in 1972. It is a wire guided SACLOS (semi-automatic command to line-of-sight) missile, which means the sight of the launch unit has to be aimed at the target to guide the missile. The MILAN can be equipped with a MIRA or MILIS thermal sight to give it night-firing ability., A writer is a person who uses written words in various styles and techniques to communicate their ideas. Writers produce various forms of literary art and creative writing such as novels, short stories, poetry, plays, screenplays, and essays as well as various reports and news articles that may be of interest to the public. Writers' texts are published across a range of media. Skilled writers who are able to use language to express ideas well often contribute significantly to the cultural content of a society. The word is also used elsewhere in the arts  such as songwriter  but as a standalone term, "writer" normally refers to the creation of written language. Some writers work from an oral tradition., Sicily is the largest island in the Mediterranean Sea. It constitutes an autonomous Region of Italy, along with surrounding minor islands, officially referred to as "Regione Siciliana" (in Italian, Sicilian Region)., A stockbroker is a regulated professional individual, usually associated with a brokerage firm or broker-dealer, who buys and sells stocks and other securities for both retail and institutional clients through a stock exchange or over the counter in return for a fee or commission. Stockbrokers are known by numerous professional designations, depending on the license they hold, the type of securities they sell, or the services they provide. In the United States, a stockbroker must pass both the Series 7 and either the Series 63 or the Series 66 exams in order to be properly licensed., L'Avventura is a 1960 Italian film directed by Michelangelo Antonioni and starring Gabriele Ferzetti, Monica Vitti, and Lea Massari. Developed from a story by Antonioni, the film is about a young woman's disappearance during a Mediterranean boating trip. Her lover and her best friend, during the subsequent search for her, become attracted to each other. The film is noted for its careful pacing, which puts a focus on visual composition and character development, as well as for its unusual narrative structure. According to an Antonioni obituary, the film "systematically subverted the filmic codes, practices and structures in currency at its time." Filmed on location in Rome, the Aeolian Islands, and Sicily in 1959 under difficult financial and physical conditions, "L'Avventura" made Monica Vitti an international star. The film was nominated for numerous awards and was awarded the Jury Prize at the 1960 Cannes Film Festival. "L'Avventura" is the first film of a trilogy by Antonioni, followed by "La Notte" (1961) and "L'Eclisse" (1962)., A trilogy (from Greek - "", "three" and - "-logia", "discourse") is a set of three works of art that are connected, and that can be seen either as a single work or as three individual works. They are commonly found in literature, film, or video games. Three-part works that are considered components of a larger work also exist, such as the triptych or the three-movement sonata, but they are not commonly referred to with the term "trilogy.", La Notte is a 1961 Italian drama film directed by Michelangelo Antonioni and starring Marcello Mastroianni, Jeanne Moreau and Monica Vitti (Umberto Eco appeared in a cameo). Filmed on location in Milan, the film is about a day in the life of an unfaithful married couple and their deteriorating relationship. In 1961 "La Notte" received the Golden Bear at the Berlin International Film Festival, as well as the David di Donatello Award for Best Director. "La Notte" is considered the central film of a trilogy beginning with "L'Avventura" (1960) and ending with "L'Eclisse" (1962)., Michelangelo Antonioni , Cavaliere di Gran Croce OMRI ( 29 September 1912 -- 30 July 2007 ) , was an Italian film director , screenwriter , editor , and short story writer . Best known for his `` trilogy on modernity and its discontents '' -- L'Avventura ( 1960 ) , La Notte ( 1961 ) , and L'Eclisse ( 1962 ) -- Antonioni `` redefined the concept of narrative cinema '' and challenged traditional approaches to storytelling , realism , drama , and the world at large . He produced `` enigmatic and intricate mood pieces '' and rejected action in favor of contemplation , focusing on image and design over character and story . His films defined a `` cinema of possibilities '' . Antonioni received numerous awards and nominations throughout his career , including the Cannes Film Festival Jury Prize ( 1960 , 1962 ) , Palme d'Or ( 1966 ) , and 35th Anniversary Prize ( 1982 ) ; the Venice Film Festival Silver Lion ( 1955 ) , Golden Lion ( 1964 ) , FIPRESCI Prize ( 1964 , 1995 ) , and Pietro Bianchi Award ( 1998 ) ; the Italian National Syndicate of Film Journalists Silver Ribbon eight times ; and an honorary Academy Award in 1995 ., Alain Fabien Maurice Marcel Delon (born 8 November 1935) is a French-Swiss actor and businessman. Delon became one of Europe's most prominent actors and screen sex symbols in the 1960s. He achieved critical acclaim for roles in films such as "Rocco and His Brothers" (1960), "Purple Noon" (1960), "L'Eclisse" (1962), "The Leopard" (1963), "Lost Command" (1966) and "Le Samouraï" (1967). Over the course of his career Delon worked with many well-known directors, including Luchino Visconti, Jean-Luc Godard, Jean-Pierre Melville, Michelangelo Antonioni and Louis Malle., Jeanne Moreau (born 23 January 1928) is a French actress, singer, screenwriter and director. She is the recipient of a César Award for Best Actress, a BAFTA Award for Best Foreign Actress and a Cannes Film Festival Best Actress Award for individual performances, and several lifetime awards., Anna Maria Massetani better known as Lea Massari (born 30 June 1933) is an Italian actress and singer., The Aeolian Islands (, , , "Aiolides Nisoi") are a volcanic archipelago in the Tyrrhenian Sea north of Sicily, named after the demigod of the winds Aeolus. The islands' inhabitants are known as Aeolians. The Aeolian Islands are a popular tourist destination in the summer and attract up to 200,000 visitors annually., A film, also called a movie, motion picture, theatrical film or photoplay, is a series of still images which, when shown on a screen, creates the illusion of moving images due to the phi phenomenon. This optical illusion causes the audience to perceive continuous motion between separate objects viewed rapidly in succession. The process of filmmaking is both an art and an industry. A film is created by photographing actual scenes with a motion picture camera; by photographing drawings or miniature models using traditional animation techniques; by means of CGI and computer animation; or by a combination of some or all of these techniques and other visual effects., A film director is a person who directs the making of a film. Generally, a film director controls a film's artistic and dramatic aspects, and visualizes the script while guiding the technical crew and actors in the fulfillment of that vision. The director has a key role in choosing the cast members, production design, and the creative aspects of filmmaking. Under European Union law, the director is viewed as the author of the film., The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency., The David di Donatello Award, named after Donatello's "David", is a film award presented each year for cinematic performances and production by L'accademia del Cinema Italiano (ACI). There are 24 categories as of 2006. Italy is also famed for its annual Venice Film Festival., The Golden Bear is the highest prize awarded for the best film at the Berlin International Film Festival. The bear is the heraldic animal of Berlin, featured on both the coat of arms and flag of Berlin., The history of comics has followed different paths in different cultures. Scholars have posited a pre-history as far back as the Lascaux cave paintings. By the mid-20th century, comics flourished particularly in the United States, western Europe (especially in France and Belgium), and Japan. The history of European comics is often traced to Rodolphe Töpffer's cartoon strips of the 1830s, and became popular following the success in the 1930s of strips and books such as "The Adventures of Tintin". American comics emerged as a mass medium in the early 20th century with the advent of newspaper comic strips; magazine-style comic books followed in the 1930s, in which the superhero genre became prominent after Superman appeared in 1938. Histories of Japanese comics and cartooning ("") propose origins as early as the 12th century. Modern comic strips emerged in Japan in the early 20th century, and the output of comics magazines and books rapidly expanded in the post-World War II era with the popularity of cartoonists such as Osamu Tezuka. had a lowbrow reputation for much of its history, but towards the end of the 20th century began to find greater acceptance with the public and in academia., A screenplay or script is a written work by screenwriters for a film, video game, or television program. These screenplays can be original works or adaptations from existing pieces of writing. In them, the movement, actions, expression, and dialogues of the characters are also narrated. A screenplay written for television is also known as a teleplay., Screenwriting, also called scriptwriting, is the art and craft of writing scripts for mass media such as feature films, television productions or video games. It is frequently a freelance profession., Martin Charles Scorsese (born November 17, 1942) is an American director, producer, screenwriter, actor, and film historian, whose career spans more than 53 years. Scorsese's body of work addresses such themes as Sicilian-American identity, Roman Catholic concepts of guilt and redemption, faith, machismo, modern crime, and gang conflict. Many of his films are also known for their depiction of violence and liberal use of profanity., My Voyage to Italy is a personal documentary by acclaimed Italian-American director Martin Scorsese. The film is a voyage through Italian cinema history, marking influential films for Scorsese and particularly covering the Italian neorealism period., The 15th Cannes Film Festival was held on May 723, 1962. The Palme d'Or went to the "O Pagador de Promessas" by Anselmo Duarte. The festival opened with "Les Amants de Teruel", directed by Raymond Rouleau., A television program is a segment of content intended for broadcast on over-the-air, cable television, or Internet television, other than a commercial, trailer, or any other segment of content not serving as attraction for viewership. It may be a single production, or more commonly, a series of related productions (also called a television series or a television show)., Gabriele Ferzetti (born Pasquale Ferzetti; 17 March 1925  2 December 2015) was an Italian actor with more than 160 credits to his name across film, television, and stage. His career was at its peak in the 1950s and 1960s., The 13th Cannes Film Festival was held from 4 to 20 May 1960. The Palme d'Or went to the "La Dolce Vita" by Federico Fellini. The festival opened with "Ben-Hur", directed by William Wyler., Marcello Vincenzo Domenico Mastroianni, Knight Grand Cross (28 September 1924  19 December 1996) was an Italian film actor. His prominent films include: "La Dolce Vita"; "8"; "La Notte"; "Divorce, Italian Style"; "Yesterday, Today and Tomorrow"; "Marriage Italian-Style"; "The 10th Victim"; "A Special Day"; "City of Women"; "Henry IV"; "Dark Eyes"; and "Stanno tutti bene". His honours included British Film Academy Awards, Best Actor awards at the Cannes Film Festival and two Golden Globe Awards., Umberto Eco (5 January 1932  19 February 2016) was an Italian novelist, literary critic, philosopher, semiotician, and university professor. He is best known internationally for his 1980 novel "Il nome della rosa" ("The Name of the Rose"), a historical mystery combining semiotics in fiction with biblical analysis, medieval studies, and literary theory. He later wrote other novels, including "Il pendolo di Foucault" ("Foucault's Pendulum") and "L'isola del giorno prima" ("The Island of the Day Before"). His novel "Il cimitero di Praga" ("The Prague Cemetery"), released in 2010, was a best-seller., L'Eclisse is a 1962 Italian drama film written and directed by Michelangelo Antonioni and starring Alain Delon and Monica Vitti. Filmed on location in Rome and Verona, "L'Eclisse" is about a young woman who breaks up with an older lover and then has an affair with a confident young stockbroker whose materialistic nature eventually undermines their relationship. The film is considered the last part of a trilogy which was preceded by "L'Avventura" (1960) and "La Notte" (1961). In Martin Scorsese's documentary "My Voyage to Italy", the director called "L'Eclisse" the boldest film in Antonioni's trilogy. "L'Eclisse" won the Special Jury Prize at the 1962 Cannes Film Festival and was nominated for the "Palme d'Or"., Subject: michelangelo antonioni, Relation: given_name, Options: (A) alain (B) an (C) anna (D) are (E) art (F) ben (G) berlin (H) can (I) cave (J) charles (K) césar (L) david (M) della (N) domenico (O) duarte (P) faith (Q) foucault (R) france (S) french (T) gabriele (U) henry (V) january (W) jean (X) jeanne (Y) june (Z) line ([) marcel (\) marcello (]) maria (^) martin (_) maurice (`) may (a) michael (b) michelangelo (c) milan (d) mira (e) monica (f) my (g) omri (h) rocco (i) roma (j) rosa (k) rose (l) set (m) stamp (n) terence (o) umberto (p) verona (q) vincenzo (r) vita (s) young

PROBLEM: Context: In vertebrates the gallbladder (also gall bladder, biliary vesicle or cholecyst) is a small organ where bile (a fluid produced by the liver) is stored and concentrated before it is released into the small intestine. Humans can live without a gallbladder. The surgical removal of the gallbladder is called a cholecystectomy., Bilirubin (formerly referred to as haematoidin and discovered by Rudolf Virchow in 1847) is a yellow compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates. This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged red blood cells. First the hemoglobin gets stripped of the heme molecule which thereafter passes through various processes of porphyrin catabolism, depending on the part of the body in which the breakdown occurs. For example, the molecules excreted in the urine differ from those in the feces. The production of biliverdin from heme is the first major step in the catabolic pathway, after which the enzyme biliverdin reductase performs the second step, producing bilirubin from biliverdin. , A bile duct is any of a number of long tube - like structures that carry bile . Bile , required for the digestion of food , is secreted by the liver into passages that carry bile toward the hepatic duct , which joins with the cystic duct ( carrying bile to and from the gallbladder ) to form the common bile duct , which opens into the intestine . The biliary tree ( see below ) is the whole network of various sized ducts branching through the liver . The path is as follows : Bile canaliculi  Canals of Hering  interlobular bile ducts  intrahepatic bile ducts  left and right hepatic ducts merge to form  common hepatic duct exits liver and joins  cystic duct ( from gall bladder ) forming  common bile duct  joins with pancreatic duct  forming ampulla of Vater  enters duodenum, Vertebrates comprise all species of animals within the subphylum Vertebrata (chordates with backbones). Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 64,000 species described. Vertebrates include the jawless fish and the jawed vertebrates, which include the cartilaginous fish (sharks and rays) and the bony fish. , Lecithin (from the Greek "lekithos", "egg yolk") is a generic term to designate any group of yellow-brownish fatty substances occurring in animal and plant tissues, which are amphiphilic - they attract both water and fatty substances (and so are both hydrophilic and lipophilic), and are used for smoothing food textures, dissolving powders (emulsifying), homogenizing liquid mixtures, and repelling sticking materials.
Lecithins are usually phospholipids, composed of phosphoric acid with choline, glycerol or other fatty acids usually glycolipids or triglyceride. Glycerophospholipids in lecithin include phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine, and phosphatidic acid., The liver is a vital organ of vertebrates and some other animals. In the human, it is located in the upper right quadrant of the abdomen, below the diaphragm. The liver has a wide range of functions, including detoxification of various metabolites, protein synthesis, and the production of biochemicals necessary for digestion., Bile or gall is a dark green to yellowish brown fluid, produced by the liver of most vertebrates, that aids the digestion of lipids in the small intestine. In humans, bile is produced continuously by the liver (liver bile), and stored and concentrated in the gallbladder (gallbladder bile). After eating, this stored bile is discharged into the duodenum. The composition of gallbladder bile is 97% water, 0.7% bile salts, 0.2% bilirubin, 0.51% fats (cholesterol, fatty acids and lecithin), and 200 meq/l inorganic salts., The duodenum
is the first section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish, the divisions of the small intestine are not as clear, and the terms anterior intestine or proximal intestine may be used instead of duodenum. In mammals the duodenum may be the principal site for iron absorption., In biology, lipids comprise a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries as well as in nanotechnology., Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream. Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use., The small intestine or small bowel is the part of the gastrointestinal tract between the stomach and the large intestine, and is where most of the end absorption of food takes place. The small intestine has three distinct regions  the duodenum, jejunum, and ileum. The duodenum receives bile and pancreatic juice through the pancreatic duct, controlled by the sphincter of Oddi. The primary function of the small intestine is the absorption of nutrients and minerals from food., Cholesterol, from the Ancient Greek "chole-" (bile) and "stereos" (solid) followed by the chemical suffix "-ol" for an alcohol, is an organic molecule. It is a sterol (or modified steroid), a type of lipid molecule, and is biosynthesized by all animal cells, because it is an essential structural component of all animal cell membranes; essential to maintain both membrane structural integrity and fluidity. Cholesterol enables animal cells to dispense with a cell wall (to protect membrane integrity and cell viability), thereby allowing animal cells to change shape and animals to move (unlike bacteria and plant cells, which are restricted by their cell walls)., Subject: bile duct, Relation: subclass_of, Options: (A) alcohol (B) ancient greek (C) animal (D) biology (E) brown (F) change (G) digestion (H) eating (I) energy (J) enzyme (K) fat (L) feces (M) fish (N) fluid (O) food (P) function (Q) greek (R) green (S) iron (T) liquid (U) majority (V) nanotechnology (W) organ (X) part (Y) plant (Z) process ([) production (\) red (]) second (^) section (_) species (`) steroid (a) sterol (b) stream (c) suffix (d) vertebrata (e) water (f) yellow
