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

Context: The vastness of Canada's Northwest Territories (spelled 'North-West Territories' from 1870 to 1905) meant that for much of its history it was divided into several districts for ease of administration. The number and size of these territorial districts varied as other provinces and territories of Canada were created and expanded. The districts of the Northwest Territories were abolished in 1999 with the creation of Nunavut territory and the contraction of the Northwest Territories to its current size., Calgary is a city in the Canadian province of Alberta.

Context: Operetta is a genre of light opera, "light" in terms both of music and subject matter., A composer (Latin "compn"; literally "one who puts together") is a person who creates or writes music, which can be vocal music (for a singer or choir), instrumental music (e.g., for solo piano, string quartet, wind quintet or orchestra) or music which combines both instruments and voices (e.g., opera or art song, which is a singer accompanied by a pianist). The core meaning of the term refers to individuals who have contributed to the tradition of Western classical music through creation of works expressed in written musical notation (e.g., sheet music scores)., Gioachino Antonio Rossini (29 February 179213 November 1868) was an Italian composer who wrote operas, as well as some sacred music, songs, chamber music and piano pieces., In the history of Europe, the Middle Ages or medieval period lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages., A Requiem or Requiem Mass, also known as Mass for the dead (Latin: "Missa pro defunctis") or Mass of the dead (Latin: "Missa defunctorum"), is a Mass in the Catholic Church offered for the repose of the soul or souls of one or more deceased persons, using a particular form of the Roman Missal. It is frequently, but not necessarily, celebrated in the context of a funeral., Matteo Maria Boiardo (1434-4119/20 December 1494) was an Italian Renaissance poet., Giuseppe Saverio Raffaele Mercadante (baptised 17 September 179517 December 1870) was an Italian composer, particularly of operas. While Mercadante may not have retained the international celebrity of Gaetano Donizetti or Gioachino Rossini beyond his own lifetime, he composed as impressive a number of works as either; and his development of operatic structures, melodic styles and orchestration contributed significantly to the foundations upon which Giuseppe Verdi built his dramatic technique., Bel canto (Italian for "beautiful singing" or "beautiful song"), along with a number of similar constructions ("bellezze del canto"/"bell'arte del canto"), is a term relating to Italian singing. It has several different meanings and is subject to a wide variety of interpretations., An oratorio is a large musical composition for orchestra, choir, and soloists. Like an opera, an oratorio includes the use of a choir, soloists, an ensemble, various distinguishable characters, and arias. However, opera is musical theatre, while oratorio is strictly a concert piecethough oratorios are sometimes staged as operas, and operas are sometimes presented in concert form. In an oratorio there is generally little or no interaction between the characters, and no props or elaborate costumes. A particularly important difference is in the typical subject matter of the text. Opera tends to deal with history and mythology, including age-old devices of romance, deception, and murder, whereas the plot of an oratorio often deals with sacred topics, making it appropriate for performance in the church. Protestant composers took their stories from the Bible, while Catholic composers looked to the lives of saints, as well as to Biblical topics. Oratorios became extremely popular in early 17th-century Italy partly because of the success of opera and the Catholic Church's prohibition of spectacles during Lent. Oratorios became the main choice of music during that period for opera audiences., Marie Sallé (17071756) was a French dancer and choreographer known for her expressive, dramatic performances rather than a series of "leaps and frolics" typical of ballet of her time., A cantata (literally "sung", past participle feminine singular of the Italian verb "cantare", "to sing") is a vocal composition with an instrumental accompaniment, typically in several movements, often involving a choir., Ludovico Ariosto (8 September 1474  6 July 1533) was an Italian poet. He is best known as the author of the romance epic "Orlando Furioso" (1516). The poem, a continuation of Matteo Maria Boiardo's "Orlando Innamorato", describes the adventures of Charlemagne, Orlando, and the Franks as they battle against the Saracens with diversions into many sideplots. Ariosto composed the poem in the ottava rima rhyme scheme and introduced narrative commentary throughout the work., Trieste is a city and seaport in northeastern Italy. It is situated towards the end of a narrow strip of Italian territory lying between the Adriatic Sea and Slovenia, which lies almost immediately south and east of the city. It is also located near Croatia some further south. Trieste is located at the head of the Gulf of Trieste and throughout history it has been influenced by its location at the crossroads of Latin, Slavic, and Germanic cultures. In 2009, it had a population of about 205,000 and it is the capital of the autonomous region Friuli-Venezia Giulia and the Province of Trieste., Antonio Salvi (17 January 1664  21 May 1724) was an Italian physician, court poet and librettist. He was in the service of the ducal court in Florence and the favourite librettist of Prince Ferdinando de' Medici. Salvi was one of the developers of the opera seria., Giovanni Pacini (11 February 17966 December 1867) was an Italian composer, best known for his operas. Pacini was born in Catania, Sicily, the son of the buffo Luigi Pacini, who was to appear in the premieres of many of Giovanni's operas. The family was of Tuscan origin, and just happened to be in Catania when the composer was born., Gaetano Rossi (18 May 1774  25 January 1855) was an Italian opera librettist for several of the well-known "bel canto"-era composers including Gioachino Rossini, Gaetano Donizetti, and Saverio Mercadante in Italy and Giacomo Meyerbeer in one of his early Italian successes. Other composers with whom he worked included Simon Mayr, a composer and Donizetti's teacher, as well as the prolific Giovanni Pacini., Johann(es) Simon Mayr (also spelled Majer, Mayer, Maier), also known in Italian as Giovanni Simone Mayr or Simone Mayr (14 June 1763  2 December 1845), was a German composer., 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., Domenico Gaetano Maria Donizetti (29 November 1797  8 April 1848) was an Italian composer. Along with Gioachino Rossini and Vincenzo Bellini, Donizetti was a leading composer of the "bel canto" opera style during the first half of the nineteenth century. Donizetti's close association with the bel canto style was undoubtedly an influence on other composers such as Giuseppe Verdi (1813 - 1901). , Orlando Innamorato ("Orlando in Love") is an epic poem written by the Italian Renaissance author Matteo Maria Boiardo. The poem is a romance concerning the heroic knight Orlando (Roland). It was published between 1483 (first two books) and 1495 (third book published separately, first complete edition)., The masque was a form of festive courtly entertainment that flourished in 16th- and early 17th-century Europe, though it was developed earlier in Italy, in forms including the intermedio (a public version of the masque was the pageant). A masque involved music and dancing, singing and acting, within an elaborate stage design, in which the architectural framing and costumes might be designed by a renowned architect, to present a deferential allegory flattering to the patron. Professional actors and musicians were hired for the speaking and singing parts. Often the masquers, who did not speak or sing, were courtiers: the English queen Anne of Denmark frequently danced with her ladies in masques between 1603 and 1611, and Henry VIII and Charles I of England performed in the masques at their courts. In the tradition of masque, Louis XIV of France danced in ballets at Versailles with music by Jean-Baptiste Lully., Ginevra di Scozia is an opera in two acts by Simon Mayr set to an Italian libretto by Gaetano Rossi based on Antonio Salvi 's Ginevra , principessa di Scozia , which in turn was adapted from Cantos 5 and 6 of Ludovico Ariosto 's Orlando Furioso . Ginevra di Scozia premiered on 21 April 1801 at the Regio Teatro Nuovo in Trieste to celebrate the inauguration of the new theatre . The story is virtually identical to that of Handel 's Ariodante which shares the same source for the libretto ., Ariodante (HWV 33) is an opera seria in three acts by George Frideric Handel. The anonymous Italian libretto was based on a work by Antonio Salvi, which in turn was adapted from Canti 5 and 6 of Ludovico Ariosto's "Orlando Furioso". Each act contains opportunities for dance, originally composed for dancer Marie Sallé and her company., A libretto is the text used in, or intended for, an extended musical work such as an opera, operetta, masque, oratorio, cantata or musical. The term "libretto" is also sometimes used to refer to the text of major liturgical works, such as the Mass, requiem and sacred cantata, or the story line of a ballet., The Adriatic Sea is a body of water separating the Italian Peninsula from the Balkan peninsula and the Apennine Mountains from the Dinaric Alps and adjacent ranges. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Greece, Italy, Montenegro and Slovenia. The Adriatic contains over 1,300 islands, mostly located along its eastern, Croatian, coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although larger amplitudes are known to occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because the Adriatic collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures generally range from in summer to in winter, significantly moderating the Adriatic Basin's climate., Friuli-Venezia Giulia is one of the 20 regions of Italy, and one of five autonomous regions with special statute. The capital is Trieste. (Note that Venezia, i.e. Venice, is "not" in this region, despite the name.) It has an area of 7,858 km² and about 1.2 million inhabitants. A natural opening to the sea for many Central European countries, the region is traversed by the major transport routes between the east and west of southern Europe. It encompasses the historical-geographical region of Friuli and a small portion of the historical region of Venezia Giulia (known in English also as Julian March), each with its own distinct history, traditions and identity. The name of the region was spelled FriuliVenezia Giulia until 2001, when, in connection with a modification of article nr. 116 of the Italian constitution, the official spelling "Friuli Venezia Giulia" was adopted., Roland (Frankish: Hruodland) (died 15 August 778) was a Frankish military leader under Charlemagne who became one of the principal figures in the literary cycle known as the Matter of France. The historical Roland was military governor of the Breton March, responsible for defending Francia's frontier against the Bretons. His only historical attestation is in Einhard's "Vita Karoli Magni", which notes he was part of the Frankish rearguard killed by rebellious Basques in Iberia at the Battle of Roncevaux Pass., Opera (English plural: "operas"; Italian plural: "opere" ) is an art form in which singers and musicians perform a dramatic work combining text (libretto) and musical score, usually in a theatrical setting. In traditional opera, singers do two types of singing: recitative, a speech-inflected style and arias, a more melodic style. Opera incorporates many of the elements of spoken theatre, such as acting, scenery, and costumes and sometimes includes dance. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor., Opera seria (plural: "opere serie"; usually called "dramma per musica" or "melodramma serio") is an Italian musical term which refers to the noble and "serious" style of Italian opera that predominated in Europe from the 1710s to c. 1770. The term itself was rarely used at the time and only attained common usage once "opera seria" was becoming unfashionable and beginning to be viewed as a historical genre. The popular rival to "opera seria" was "opera buffa," the 'comic' opera that took its cue from the improvisatory commedia dell'arte., Giacomo Meyerbeer (born Jacob Liebmann Beer; 5 September 1791  2 May 1864) was a German opera composer of Jewish birth who has been described as perhaps the most successful stage composer of the nineteenth century. With his 1831 opera "Robert le diable" and its successors, he gave the genre of grand opera 'decisive character'. Meyerbeer's grand opera style was achieved by his merging of German orchestra style with Italian vocal tradition. These were employed in the context of sensational and melodramatic libretti created by Eugène Scribe and were enhanced by the up-to-date theatre technology of the Paris Opéra. They set a standard which helped to maintain Paris as the opera capital of the nineteenth century., Ballet is a type of performance dance that originated in the Italian Renaissance courts of the 15th century and later developed into a concert dance form in France and Russia. It has since become a widespread, highly technical form of dance with its own vocabulary based on French terminology. It has been globally influential and has defined the foundational techniques used in many other dance genres. Becoming a ballet dancer requires years of training. Ballet has been taught in various schools around the world, which have historically incorporated their own cultures to evolve the art., Orlando Furioso ("The Frenzy of Orlando", more literally "Raging Roland"; in Italian "furioso" is seldom capitalized) is an Italian epic poem by Ludovico Ariosto which has exerted a wide influence on later culture. The earliest version appeared in 1516, although the poem was not published in its complete form until 1532. "Orlando Furioso" is a continuation of Matteo Maria Boiardo's unfinished romance "Orlando Innamorato" ("Orlando in Love", published posthumously in 1495). In its historical setting and characters, it shares some features with the Old French "Chanson de Roland" of the eleventh century, which tells of the death of Roland. The story is also a chivalric romance which stemmed from a tradition beginning in the late Middle Ages and continuing in popularity in the 16th century and well into the 17th., As a literary genre of high culture, romance or chivalric romance is a type of prose and verse narrative that was popular in the aristocratic circles of High Medieval and Early Modern Europe. They were fantastic stories about marvel-filled adventures, often of a knight-errant portrayed as having heroic qualities, who goes on a quest, yet it is "the emphasis on love and courtly manners distinguishes it from the "chanson de geste" and other kinds of epic, in which masculine military heroism predominates." Popular literature also drew on themes of romance, but with ironic, satiric or burlesque intent. Romances reworked legends, fairy tales, and history to suit the readers' and hearers' tastes, but by c. 1600 they were out of fashion, and Miguel de Cervantes famously burlesqued them in his novel "Don Quixote". Still, the modern image of "medieval" is more influenced by the romance than by any other medieval genre, and the word "medieval" evokes knights, distressed damsels, dragons, and other romantic tropes., Croatia, officially the Republic of Croatia, is a sovereign state between Central Europe, Southeast Europe, and the Mediterranean. Its capital city is Zagreb, which forms one of the country's primary subdivisions, along with its twenty counties. Croatia covers and has diverse, mostly continental and Mediterranean climates. Croatia's Adriatic Sea coast contains more than a thousand islands. The country's population is 4.28 million, most of whom are Croats, with the most common religious denomination being Roman Catholicism., Subject: ginevra di scozia, Relation: genre, Options: (A) art (B) ballet (C) bible (D) burlesque (E) cantata (F) celebrity (G) chamber music (H) chanson (I) classical music (J) comic (K) concert (L) country (M) culture (N) dance (O) dramatic (P) entertainment (Q) epic (R) epic poem (S) family (T) fashion (U) genre (V) history (W) libretto (X) literature (Y) love (Z) march ([) mass (\) melodramma (]) military (^) music (_) mythology (`) novel (a) opera (b) opera buffa (c) opera seria (d) operetta (e) oratorio (f) poet (g) prose (h) renaissance (i) romance (j) song (k) variety (l) western
