Context: Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. Calcite is an ionic salt called calcium carbonate or CaCO. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells (coccoliths) shed from micro-organisms called coccolithophores. Flint (a type of chert unique to chalk) is very common as bands parallel to the bedding or as nodules embedded in chalk. It is probably derived from sponge spicules or other siliceous organisms as water is expelled upwards during compaction. Flint is often deposited around larger fossils such as Echinoidea which may be silicified (i.e. replaced molecule by molecule by flint)., The Indo-European languages are a language family of several hundred related languages and dialects. There are about 445 living Indo-European languages, according to the estimate by "Ethnologue", with over two-thirds (313) of them belonging to the Indo-Iranian branch. The most widely spoken Indo-European languages by native speakers are Spanish, English, Hindustani (Hindi and Urdu), Portuguese, Bengali, Russian, Persian and Punjabi, each with over 100 million speakers. Today, 46% of the human population speaks an Indo-European language natively, by far the highest of any language family., The Paleogene (or ; also spelled Palaeogene or Palæogene; informally Lower Tertiary) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago (Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The Paleogene is most notable for being the time during which mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of the CretaceousPaleogene extinction event that ended the preceding Cretaceous Period. , The Cretaceous is a geologic period and system that spans 79 million years from the end of the Jurassic Period million years ago (Mya) to the beginning of the Paleogene Period Mya. It is the last period of the Mesozoic Era. The Cretaceous Period is usually abbreviated K, for its German translation "Kreide" (chalk)., Latin (Latin: ) is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets., Bison are large, even-toed ungulates in the genus "Bison" within the subfamily Bovinae., Silvisaurus , from the Latin silva `` woodland '' and Greek sauros `` lizard '' , is a nodosaurid ankylosaur from the middle Cretaceous of Kansas ., Kansas is a U.S. state located in the Midwestern United States. Its capital is Topeka and its largest city is Wichita. Kansas is named after the Kansa Native American tribe, which inhabited the area. The tribe's name (natively "") is often said to mean "people of the wind" or "people of the south wind", although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison., Subject: silvisaurus, Relation: taxon_rank, Options: (A) branch (B) family (C) form (D) genus (E) group (F) tribe

Context: An electric guitar is a fretted string instrument that uses a pickup to convert the vibration of its stringswhich are typically made of steel, and which occurs when a guitarist strums, plucks or fingerpicks the stringsinto electrical signals. The vibrations of the strings are sensed by a pickup, of which the most common type is the magnetic pickup, which uses the principle of direct electromagnetic induction. The signal generated by an electric guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker, which makes a sound loud enough to hear. The output of an electric guitar is an electric signal, and the signal can easily be altered by electronic circuits to add "color" to the sound or change the sound. Often the signal is modified using effects such as reverb and distortion and "overdrive", with the latter being a key element of the sound of the electric guitar as it is used in blues and rock music., String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when the performer plays or sounds the strings in some manner. , Nylon is a generic designation for a family of synthetic polymers, more specifically aliphatic or semi-aromatic polyamides. They can be melt-processed into fibers, films or shapes. The first example of nylon (nylon 6,6) was produced on February 28, 1935, by Wallace Carothers at DuPont's research facility at the DuPont Experimental Station. Nylon polymers have found significant commercial applications in fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging).<ref name="Materials/Polyamide"></ref>, The gittern was a relatively small gut strung round-backed instrument that first appears in literature and pictorial representation during the 13th century in Western Europe (Iberian Peninsula, Italy, France, England). It is usually depicted played with a quill plectrum, as we can see clearly beginning in manuscript illuminations from the thirteenth century. 
It was also called the guitarra in Spain, guiterne or guiterre in France, the chitarra in Italy and quintern in Germany. A popular instrument with court musicians, minstrels, and amateurs, the gittern is considered ancestral to the modern guitar; possibly other instruments like the mandore and gallichon., Punk rock (or simply "punk") is a rock music genre that developed in the early to mid 1970s in the United States, United Kingdom, and Australia. Rooted in 1960s garage rock and other forms of what is now known as "proto-punk" music, punk rock bands rejected perceived excesses of mainstream 1970s rock. Punk bands typically use short or fast-paced songs, with hard-edged melodies and singing styles, stripped-down instrumentation, and often political, anti-establishment lyrics. Punk embraces a DIY ethic; many bands self-produce recordings and distribute them through informal channels., Post-hardcore is a punk rock music genre that derives from hardcore punk, maintaining hardcore's aggression and intensity, but emphasizes a greater degree of creative expression initially inspired by post-punk and noise rock. Like post-punk, the term has been applied to a broad constellation of groups. The genre took shape in the mid to late 1980s with releases by bands from cities that had established hardcore scenes, such as Fugazi from Washington, D.C. as well as groups such as Big Black and Jawbox that stuck closer to post-hardcore's noise rock roots., The guitar is a musical instrument classified as a string instrument with anywhere from four to 18 strings, usually having six. The sound is projected either acoustically, using a hollow wooden or plastic and wood box (for an acoustic guitar), or through electrical amplifier and a speaker (for an electric guitar). It is typically played by strumming or plucking the strings with the fingers, thumb and/or fingernails of the right hand or with a pick while fretting (or pressing against the frets) the strings with the fingers of the left hand. The guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning. The modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument., Jawbox was an American alternative rock band from Washington, D.C., United States. Its original members were J. Robbins (vocals, guitar), Kim Coletta (bass guitar) and Adam Wade (drums). Bill Barbot (vocals, guitar) and Zach Barocas (drums) later joined the group, with Barocas replacing Wade., Noise rock is a style of experimental rock rooted in noise music. The genre, which gained prominence in the 1980s, makes use of the traditional instrumentation and iconography of rock music, but incorporates atonality and especially dissonance, and frequently discards typical songwriting conventions. Noise rock developed from early avant-garde music, sound art, and rock songs featuring extremely dissonant sounds and electronic feedback. The New York no wave scene, featuring such artists as Mars and Teenage Jesus and the Jerks in the late 1970s, was an essential development in noise rock. , A fret is a raised element on the neck of a stringed instrument. Frets usually extend across the full width of the neck. On most modern western fretted instruments, frets are metal strips inserted into the fingerboard. On some historical instruments and non-European instruments, frets are made of pieces of string tied around the neck. , Mukilteo, which means "good camping ground," is a waterfront city in Snohomish County, Washington, United States. The population was 20,254 at the 2010 census. It is on the shore of the Puget Sound, and is the site of a Washington State Ferries terminal linking it to Clinton, on Whidbey Island., thumb
Andrew Forsman is an American drummer and percussionist from Mukilteo, Washington, known as one of the founding members of the Seattle-based progressive rock band The Fall of Troy., Post-punk (originally "new musick") is a broad type of rock music that emerged from the punk movement of the 1970s, in which artists departed from punk rock's raw, accessible style to pursue a variety of avant-garde sensibilities. Attempting to break from rock tradition, post-punk artists experimented with sources such as electronic music, black dance music and the avant-garde, as well as novel recording technology and production techniques. The movement also saw the frequent intersection of music with art and politics, as artists incorporated ideas from sources such as modernist literature, critical theory, cinema, and performance art. Accompanying these musical developments were communities that produced independent record labels, visual art, multimedia performances and fanzines in conjunction with the music., Hardcore punk (often abbreviated to hardcore) is a punk rock music genre that originated in the late 1970s. It is generally faster, harder, and more aggressive than other forms of punk rock. Its roots can be traced to earlier punk scenes in San Francisco and Southern California which arose as a reaction against the still predominant hippie cultural climate of the time and was also inspired by New York punk rock and early proto-punk. New York punk had a harder-edged sound than its San Francisco counterpart, featuring anti-art expressions of masculine anger, energy and subversive humor. Hardcore punk generally disavows commercialism, the established music industry and "anything similar to the characteristics of mainstream rock" and often addresses social and political topics., The Renaissance was a period in European history, from the 14th to the 17th century, regarded as the cultural bridge between the Middle Ages and modern history. It started as a cultural movement in Italy in the Late Medieval period and later spread to the rest of Europe, marking the beginning of the Early Modern Age., The Fall of Troy is an American post-hardcore band from Mukilteo , Washington . The band is a trio consisting of Thomas Erak ( guitars , vocals , keyboards ) , Andrew Forsman ( drums , percussion ) and Tim Ward ( bass , screamed vocals ) who was later replaced by Frank Ene following his departure from the band in late 2007 . Ene would remain in the band until their initial break - up in 2010 , but Ward rejoined the band in Ene 's place for their reunion in 2013 . The trio is known for their technical , intricate style , unorthodox song structures and energetic stage presence . Erak 's alternating guitar riffs and rhythmic chord work , paired with unconventional time signatures set the band apart from other post-hardcore bands during their career . They were also known for interchanging clean vocals and harsh screams , which was often split between Erak and Ward , respectively . Over the course of their career , the group released four full - length albums , one EP , and one single . Prior to The Fall of Troy 's formation , when each member was about 17 years old , all three founding members were in another group named The 30 Years War , who released two EPs ., Washington State Ferries (WSF) is a government agency that operates automobile and passenger ferry service in the U.S. state of Washington as part of the Washington State Department of Transportation. It runs ten routes serving 20 terminals located around Puget Sound and in the San Juan Islands, designated as part of the state highway system. The agency maintains the largest fleet of ferries in the United States at 22 vessels, carrying 23 million passengers in 2014. , it was the largest ferry operator in the United States, and the fourth-largest ferry system in the world., A census is the procedure of systematically acquiring and recording information about the members of a given population. It is a regularly occurring and official count of a particular population. The term is used mostly in connection with national population and housing censuses; other common censuses include agriculture, business, and traffic censuses. The United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every 10 years. United Nations recommendations also cover census topics to be collected, official definitions, classifications and other useful information to co-ordinate international practice., Big Black was an American punk rock band from Evanston, Illinois, active from 1981 to 1987. Founded by singer and guitarist Steve Albini, the band's initial lineup also included guitarist Santiago Durango and bassist Jeff Pezzati, both of Naked Raygun. In 1985 Pezzati was replaced by Dave Riley, who played on Big Black's two full-length studio albums, "Atomizer" (1986) and "Songs About Fucking" (1987)., The Baroque guitar (c. 16001750) is a string instrument with five courses of gut strings and moveable gut frets. The first (highest pitched) course sometimes used only a single string., Whidbey Island (historical spellings Whidby, Whitbey, or Whitby) is the largest of the islands composing Island County, Washington, in the United States. (The other large island is Camano Island, east of Whidbey.) Whidbey is about north of Seattle, and lies between the Olympic Peninsula and the I-5 corridor of western Washington. The island forms the northern boundary of Puget Sound. It is home to Naval Air Station Whidbey Island., A chordophone is a musical instrument that makes sound by way of a vibrating string or strings stretched between two points. It is one of the four main divisions of instruments in the original Hornbostel-Sachs scheme of musical instrument classification., Subject: the fall of troy, Relation: genre, Options: (A) alternative rock (B) atonality (C) automobile (D) baroque (E) blues (F) critical theory (G) dance (H) dance music (I) diy (J) experimental rock (K) family (L) food (M) government (N) hardcore punk (O) information (P) literature (Q) manuscript (R) music (S) musical (T) noise (U) noise rock (V) novel (W) percussion (X) politics (Y) progressive rock (Z) punk rock ([) renaissance (\) research (]) rock (^) technology (_) western
