[EX Q]: Context: Hummingbirds are birds from the Americas that constitute the family Trochilidae. They are among the smallest of birds, most species measuring . Indeed, the smallest extant bird species is a hummingbird, the 5-cm bee hummingbird weighing less than a U.S. penny (2.5 g)., The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes. The heart is located between the lungs, in the middle compartment of the chest.
In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria; and lower left and right ventricles. Commonly the right atrium and ventricle are referred together as the "right heart" and their left counterparts as the "left heart". Fish in contrast have two chambers, an atrium and a ventricle, while reptiles have three chambers. In a healthy heart blood flows one way through the heart due to heart valves, which prevent backflow. The heart is enclosed in a protective sac, the pericardium, which also contains a small amount of fluid. The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium.
The heart pumps blood with a rhythm determined by a group of pacemaking cells in the sinoatrial node. These generate a current that causes contraction of the heart, traveling through the atrioventricular node and along the conduction system of the heart. The heart receives blood low in oxygen from the systemic circulation, which enters the right atrium from the superior and inferior venae cavae and passes to the right ventricle. From here it is pumped into the pulmonary circulation, through the lungs where it receives oxygen and gives off carbon dioxide. Oxygenated blood then returns to the left atrium, passes through the left ventricle and is pumped out through the aorta to the systemic circulationwhere the oxygen is used and metabolized to carbon dioxide. The heart beats at a resting rate close to 72 beats per minute. Exercise temporarily increases the rate, but lowers resting heart rate in the long term, and is good for heart health.
Cardiovascular diseases (CVD) are the most common cause of death globally as of 2008, accounting for 30% of deaths. Of these more than three quarters are a result of coronary artery disease and stroke. Risk factors include: smoking, being overweight, little exercise, high cholesterol, high blood pressure, and poorly controlled diabetes, among others. Cardiovascular diseases frequently have no symptoms or may cause chest pain or shortness of breath. Diagnosis of heart disease is often done by the taking of a medical history, listening to the heart-sounds with a stethoscope, ECG, and ultrasound. Specialists who focus on diseases of the heart are called cardiologists, although many specialties of medicine may be involved in treatment., Dinosaurs are a diverse group of animals of the clade Dinosauria that first appeared during the Triassic. Although the exact origin and timing of the evolution of dinosaurs is the subject of active research, the current scientific consensus places their origin between 231 and 243 million years ago. They became the dominant terrestrial vertebrates after the TriassicJurassic extinction event 201 million years ago. Their dominance continued through the Jurassic and Cretaceous periods and ended when the CretaceousPaleogene extinction event led to the extinction of most dinosaur groups 66 million years ago., Australasia, a region of Oceania, comprises Australia, New Zealand, the island of New Guinea, and neighbouring islands in the Pacific Ocean. Charles de Brosses coined the term (as French "Australasie") in "Histoire des navigations aux terres australes" (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific (Magellanica). The bulk of Australasia sits on the Indo-Australian Plate, together with India., Birds (Aves), also known as avian dinosaurs, are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds., The ear is the organ of hearing and, in mammals, balance. In mammals, the ear is usually described as having three partsthe outer ear, middle ear and the inner ear. The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals, the word "ear" often refers to the external part alone. The middle ear includes the tympanic cavity and the three ossicles. The inner ear sits in the bony labyrinth, and contains structures which are key to several senses: the semicircular canals, which enable balance and eye tracking when moving; the utricle and saccule, which enable balance when stationary; and the cochlea, which enables hearing. The ears of vertebrates are placed somewhat symmetrically on either side of the head, an arrangement that aids sound localisation., The Australian magpie ("Cracticus tibicen") is a medium-sized black and white passerine bird native to Australia and southern New Guinea. Although once considered to be three separate species, it is now considered to be one, with nine recognised subspecies. A member of the Artamidae, the Australian magpie is classified in the butcherbird genus "Cracticus" and is most closely related to the black butcherbird ("C. quoyi"). It is not, however, related to the European magpie, which is a corvid. The adult Australian magpie is a fairly robust bird ranging from in length, with distinctive black and white plumage, gold brown eyes and a solid wedge-shaped bluish-white and black bill. The male and female are similar in appearance, and can be distinguished by differences in back markings.The male has pure white feathers on the back of the head and the female has white blending to gray feathers on the back of the head. With its long legs, the Australian magpie walks rather than waddles or hops and spends much time on the ground., The beak, bill, or rostrum is an external anatomical structure of birds that is used for eating and for grooming, manipulating objects, killing prey, fighting, probing for food, courtship and feeding young. The terms "beak" and "rostrum" are also used to refer to a similar mouth part in some dicynodonts, Ornithischians, cephalopods, cetaceans, billfishes, pufferfishes, turtles, Anuran tadpoles and sirens., The black - backed butcherbird ( Cracticus mentalis ) is a species of bird in the family Artamidae . It is found in Papua New Guinea , Indonesia , and northern Queensland in Australia ., 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. , An endotherm (from Greek  "endon" "within" and  "therm" "heat") is an organism that maintains its body at a metabolically favorable temperature, largely by the use of heat set free by its internal bodily functions instead of relying almost purely on ambient heat. Such internally generated heat is mainly an incidental product of the animal's routine metabolism, but under conditions of excessive cold or low activity an endotherm might apply special mechanisms adapted specifically to heat production. Examples include special-function muscular exertion such as shivering, and uncoupled oxidative metabolism such as within brown adipose tissue.
Only birds and mammals are extant universally endothermic groups of animals. Certain lamnid sharks, tuna and billfishes are also endothermic., A songbird is a bird belonging to the clade Passeri of the perching birds (Passeriformes). Another name that is sometimes seen as a scientific or vernacular name is Oscines, from Latin "oscen", "a songbird". This group contains some 4,000 species found all over the world, in which the vocal organ typically is developed in such a way as to produce a diverse and elaborate bird song., Currawongs are three species of medium-sized passerine birds belonging to the genus "Strepera" in the family Artamidae native to Australasia. These are the grey currawong ("Strepera versicolor"), pied currawong ("S. graculina"), and black currawong ("S. fuliginosa"). The common name comes from the call of the familiar pied currawong of eastern Australia and is onomatopoeic. They were formerly known as crow-shrikes or bell-magpies. Despite their resemblance to crows and ravens, they are only distantly related to the corvidae, instead belonging to an Afro-Asian radiation of birds of superfamily Malaconotoidea., A passerine is any bird of the order Passeriformes, which includes more than half of all bird species. A notable feature of passerines compared to other orders of Aves is the arrangement of their toes, three pointing forward and one back, which facilitates perching. Sometimes known as perching birds or, less accurately, as songbirds, the passerines form one of the most diverse terrestrial vertebrate orders, with over 5,000 identified species. It has roughly twice as many species as the largest of the mammal orders, the Rodentia. It contains more than 110 families, the second-most of any order of tetrapods (after Squamata, the scaled reptiles).
The passerines contain several groups of brood parasites such as the viduas, cuckoo-finches, and the cowbirds. Most passerines are omnivorous, while the shrikes are carnivorous., The ostrich or common ostrich ("Struthio camelus") is either one or two species of large flightless birds native to Africa, the only living member(s) of the genus "Struthio", which is in the ratite family. In 2014, the Somali ostrich ("Struthio molybdophanes") was recognized as a distinct species., Peltops is a genus of bird in the family Artamidae. The genus contains two species endemic to the island of New Guinea. The genus was once placed with the monarch flycatchers, but molecular and morphometric studies place it closer to the butcherbirds, possibly as a sister taxon to this group. The genus is named for the Greek "pelte" meaning small shield and "ops" meaning face. The species have also had the common name of shieldbill., The Cracticinae, bellmagpies and allies, gathers together 12 species of mostly crow-like birds native to Australasia and nearby areas., Butcherbirds are magpie-like birds in the genus "Cracticus." They are native to Australasia. The Australian magpie has recently been placed in the same genus, and this new taxonomy has been supported by recent phylogenetic analyses. Together with three species of currawong and two species of peltops, butcherbirds and the Australian magpie form the subfamily Cracticinae in the family Artamidae., The superclass Tetrapoda (Ancient Greek s tetrapods, "four-footed"), or the tetrapods , comprises the first four-limbed vertebrates and their descendants, including the living and extinct amphibians, birds, mammals, reptiles and some ancient, exclusively aquatic creatures such as the Acanthostega. Tetrapods evolved from the lobe-finned fishes around 390 million years ago in the middle Devonian Period, with modern tetrapod groups having appeared by the late Devonian, 367.5 million years ago. The specific aquatic ancestors of the tetrapods, and the process by which land colonization occurred, remain unclear, and are areas of active research and debate among palaeontologists at present., Feathers are epidermal growths that form the distinctive outer covering, or plumage, on birds. They are considered the most complex integumentary structures found in vertebrates, and indeed a premier example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant birds from other living groups., New Guinea (or, historically, "") is a large Island in the South West Pacific region., The bee hummingbird, zunzuncito or Helena hummingbird ("Mellisuga helenae") is a species of hummingbird., Subject: black-backed butcherbird, Relation: instance_of, Options: (A) 12 (B) animal (C) bee (D) bell (E) bill (F) bird (G) cause (H) chest (I) class (J) complex (K) event (L) extinct (M) extinction (N) family (O) fish (P) fluid (Q) food (R) four (S) genus (T) group (U) health (V) hearing (W) history (X) humans (Y) india (Z) island ([) killing (\) may (]) medicine (^) member (_) nine (`) ocean (a) organ (b) organism (c) period (d) plate (e) process (f) production (g) range (h) rank (i) region (j) research (k) result (l) shield (m) side (n) size (o) skeleton (p) song (q) species (r) system (s) taxon (t) taxonomy (u) temperature (v) three (w) two

[EX Q]: Context: Approximately 330 to 360 million people speak English as their first language.
More than half of these (231 million) live in the United States, followed by some 55 million in England, the first place where English was spoken., Tain (Gaelic: "Baile Dhubhthaich") is a royal burgh and parish in the County of Ross, in the Highlands of Scotland., A research university is a university that expects all its tenured and tenure-track faculty to continuously engage in research, as opposed to merely requiring it as a condition of an initial appointment or tenure. Such universities can be recognized by their strong focus on innovative research and the prestige of their brand names. On the one hand, research universities strive to recruit faculty who are the most brilliant minds in their disciplines in the world, and their students enjoy the opportunity to learn from such experts. On the other hand, new students are often disappointed to realize their undergraduate courses at research universities are overly academic and fail to provide vocational training with immediate "real world" applications; but many employers value degrees from research universities because they know that such coursework develops fundamental skills like critical thinking. , The Bristol Channel is a major inlet in the island of Great Britain, separating South Wales from Devon and Somerset in South West England. It extends from the lower estuary of the River Severn to the North Atlantic Ocean. It takes its name from the English city of Bristol, and is over 30 miles (50 km) across at its widest point., Vellum (derived from the Latin word "vitulinum" meaning "made from calf", leading to Old French "vélin", "calfskin") often refers to a parchment made from calf skin, as opposed to that from other animals. It is prepared for writing or printing on, to produce single pages, scrolls, codices or books. The term is sometimes used with a more general meaning referring to finer-quality parchments made from a variety of animal skins., Great Britain, also known as Britain , is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago., The University of Paris, metonymically known as the Sorbonne (its historical house), was a university in Paris, France. Appearing around 1150 as a corporation associated with the Notre Dame de Paris cathedral school, it was the second-oldest modern university in Europe. Chartered in 1200 by King Philip II (Philippe-Auguste) of France and recognised in 1215 by Pope Innocent III, it was often nicknamed after its theology collegiate institution, College of Sorbonne, founded about 1257 by Robert de Sorbon., Oxbridge is a portmanteau (blend word) of the University of Oxford and the University of Cambridge in the United Kingdom. The term is used to refer to them collectively in contrast to other British universities and more broadly to describe characteristics reminiscent of them, often with implications of superior social or intellectual status., A royal charter is a formal document issued by a monarch as letters patent, granting a right or power to an individual or a body corporate. They were, and are still, used to establish significant organisations such as cities (with municipal charters) or universities and learned societies. Charters should be distinguished from warrants and letters of appointment, as they have perpetual effect. Typically, a Royal Charter is produced as a high-quality work of calligraphy on vellum. The British monarchy has issued over 980 royal charters. Of these about 750 remain in existence. The earliest was to the town of Tain in 1066, making it the oldest Royal Burgh in Scotland, followed by the University of Cambridge in 1231. Charters continue to be issued by the British Crown, a recent example being that awarded to the Chartered Institute for the Management of Sport and Physical Activity, on 7 April 2011., Brecon, archaically known as Brecknock, is a market town and community in Powys, Mid Wales, with a population in 2001 of 7,901, increasing to 8,250 at the 2011 census. Historically it was the county town of Brecknockshire; although its role as such was eclipsed with the formation of the County of Powys, it remains an important local centre. Brecon is the third-largest town in Powys, after Newtown and Ystradgynlais. It lies north of the Brecon Beacons mountain range, but is just within the Brecon Beacons National Park., Jesus College (in full: Jesus College in the University of Oxford of Queen Elizabeth's Foundation) is one of the colleges of the University of Oxford in England. It is in the centre of the city, on a site between Turl Street, Ship Street, Cornmarket Street and Market Street. The college was founded by Elizabeth I on 27 June 1571 for the education of clergy, though students now study a broad range of secular subjects. A major driving force behind the establishment of the college was Hugh Price (or Ap Rhys), a churchman from Brecon in Wales. The oldest buildings, in the first quadrangle, date from the 16th and early 17th centuries; a second quadrangle was added between about 1640 and about 1713, and a third quadrangle was built in about 1906. Further accommodation was built on the main site to mark the 400th anniversary of the college, in 1971, and student flats have been constructed at sites in north and east Oxford., Yr Wyddfa commonly known as Snowdon in English, is the highest mountain in Wales, at an elevation of above sea level, and the highest point in the British Isles south of the Scottish Highlands. It is located in Snowdonia National Park (") in Gwynedd, and has been described as "probably the busiest mountain in Britain". It is designated as a national nature reserve for its rare flora and fauna., Jesus College , Oxford , the first Protestant college at the University of Oxford , was founded by Elizabeth I in 1571 at the instigation of a Welsh clergyman , Hugh Price . The royal charter issued by Elizabeth appointed a Principal and various Fellows , Scholars and Commissioners : the Fellows to educate the Scholars and to run the college , under the overall direction of the Principal ; and the Commissioners to draw up statutes for the governance of the college , its officers and servants , and the management of the college property . The college was founded to help with the increased numbers of Welsh students at Oxford , and the founding Fellows included a number of individuals with links to Wales . The Commissioners included prominent individuals such as William Cecil , Lord Burghley , the Principal Secretary of State . The charter also gave land and buildings in Oxford to the new college . Whilst the foundation process of the college started in 1571 , it took more than fifty years and a further two charters , one in 1589 from Elizabeth and one in 1622 from her successor , James I , to complete the process . These further charters were necessary because neither the Commissioners appointed by the 1571 charter nor those appointed by the 1589 charter fulfilled their allotted task of drawing up statutes . During this time , Griffith Powell ( one of the Fellows who was pressing for statutes to be drawn up ) concluded that successive Principals were loath to have statutes , since these would limit the Principal 's powers . One Principal lost a draft copy of the statutes ; the next kept the next draft in his study for several years without taking steps to have them confirmed by the Commissioners . It was not until after the 1622 charter that statutes were approved by the Commissioners and the college was fully constituted . Despite the intention on the foundation of the college , none of the charters made special provision for Welsh students , although the students were predominantly Welsh from the outset ., The University of Oxford (informally Oxford University or simply Oxford) is a collegiate research university located in Oxford, England, United Kingdom. While having no known date of foundation, there is evidence of teaching as far back as 1096, making it the oldest university in the English-speaking world and the world's second-oldest university in continuous operation. It grew rapidly from 1167 when Henry II banned English students from attending the University of Paris. After disputes between students and Oxford townsfolk in 1209, some academics fled northeast to Cambridge where they established what became the University of Cambridge. The two "ancient universities" are frequently jointly referred to as "Oxbridge"., Letters patent (always in the plural) are a type of legal instrument in the form of a published written order issued by a monarch, president, or other head of state, generally granting an office, right, monopoly, title, or status to a person or corporation. Letters patent can be used for the creation of corporations or government offices, or for the granting of city status or a coat of arms. Letters patent are issued for the appointment of representatives of the Crown, such as governors and governors-general of Commonwealth realms, as well as appointing a Royal Commission. In the United Kingdom they are also issued for the creation of peers of the realm. A particular form of letters patent has evolved into the modern patent (referred to as a utility patent or design patent in United States patent law) granting exclusive rights in an invention (or a design in the case of a design patent). In this case it is essential that the written grant should be in the form of a public document so other inventors can consult it to avoid infringement and also to understand how to "practice" the invention, i.e., put it into practical use., Cornmarket Street (often called just Cornmarket or historically The Corn by Oxonians) is a major shopping street and pedestrian precinct in Oxford, England that runs north-south between Carfax Tower and Magdalen Street., A city charter or town charter (generically, municipal charter) is a legal document ("charter") establishing a municipality such as a city or town. The concept developed in Europe during the Middle Ages., The Irish Sea (, , , Ulster-Scots: "Airish Sea"), separates the islands of Ireland and Great Britain. It is connected to the Celtic Sea in the south by St George's Channel, and to the Inner Seas off the West Coast of Scotland in the north by the North Channel. Anglesey is the largest island within the Irish Sea, followed by the Isle of Man. The sea is occasionally, but rarely, referred to as the Manx Sea., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight., A country is a region that is identified as a distinct national entity in political geography. A country may be an independent sovereign state or one that is occupied by another state, as a non-sovereign or formerly sovereign political division, or a geographic region associated with sets of previously independent or differently associated people with distinct political characteristics. Regardless of the physical geography, in the modern internationally accepted legal definition as defined by the League of Nations in 1937 and reaffirmed by the United Nations in 1945, a resident of a country is subject to the independent exercise of legal jurisdiction., Wales is a country that is part of the United Kingdom and the island of Great Britain. It is bordered by England to the east, the Irish Sea to the north and west, and the Bristol Channel to the south. It had a population in 2011 of 3,063,456 and has a total area of . Wales has over of coastline and is largely mountainous, with its higher peaks in the north and central areas, including Snowdon, its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate., Oxford is a city in the South East region of England and the county town of Oxfordshire. With a population of 159,994 it is the 52nd largest city in the United Kingdom, and one of the fastest growing and most ethnically diverse. The city is situated from London, from Bristol, from both Southampton and Birmingham and from Reading., Turl Street is an historic street in central Oxford, England., Cambridge is a university city and the county town of Cambridgeshire, England, on the River Cam about north of London. At the United Kingdom Census 2011, its population was 123,867, including 24,488 students., Subject: list of founding fellows, Relation: is_a_list_of, Options: (A) animal (B) cathedral (C) city (D) country (E) county (F) england (G) island (H) king (I) kingdom of great britain (J) language (K) monarch (L) mountain (M) mountain range (N) name (O) park (P) people (Q) person (R) pope (S) population (T) president (U) role (V) school (W) shopping street (X) single (Y) sovereign state (Z) street ([) term (\) tower (]) town (^) track (_) university (`) word (a) work

[EX Q]: Context: Lucio Fulci (17 June 1927  13 March 1996) was an Italian film director, screenwriter and actor. He is perhaps best known for his gore films, including "Zombi 2" (1979) and "The Beyond" (1981), although he made films in genres as diverse as giallo, western and comedy. Fulci is known as the "Godfather of Gore", a title also given to Herschell Gordon Lewis., Herschell Gordon Lewis (June 15, 1926  September 26, 2016) was an American filmmaker, best known for creating the "splatter" subgenre of horror films. He is often called the "Godfather of Gore", though his film career included works in a range of exploitation film genres including juvenile delinquent films, nudie-cuties, two children's films and at least one rural comedy. On Lewis' career, AllMovie wrote: "With his better-known gore films, Herschell Gordon Lewis was a pioneer, going farther than anyone else dared, probing the depths of disgust and discomfort onscreen with more bad taste and imagination than anyone of his era.", City of the Living Dead ( Italian : Paura nella città dei morti viventi ( English translation : Fear in the City of the Living Dead ) , also known as The Gates of Hell ) is a 1980 Italian horror film directed by Lucio Fulci . It is the first installment of the unofficial Gates of Hell trilogy which also includes The Beyond and The House by the Cemetery . Fulci makes an uncredited cameo appearance as Dr. Joe Thompson in the film ., Zombi 2 is a 1979 zombie film directed by Lucio Fulci. The film was adapted from an original screenplay by Dardano Sacchetti to serve as a sequel to George A. Romero's "Dawn of the Dead", released in Italy as "Zombi". It stars Tisa Farrow, Ian McCulloch and Richard Johnson, and featured a score by frequent Fulci collaborator Fabio Frizzi., Subject: city of the living dead, Relation: composer, Options: (A) fabio frizzi (B) herschell gordon lewis (C) johnson
