Q: 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.

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

Q: Context: Fiddle is another name for the bowed string musical instrument more often called a violin. It is also a colloquial term for the instrument used by players in all genres, including classical music. Fiddle playing, or fiddling, refers to various styles of music. Fiddle is also a common term among musicians who play folk music on the violin. The fiddle is part of many traditional (folk) styles of music which are aural traditions, taught 'by ear' rather than via written music. Fiddle is normally the term used for Irish Traditional Music., A chant (from French ', from Latin ', "to sing") is the rhythmic speaking or singing of words or sounds, often primarily on one or two main pitches called reciting tones. Chants may range from a simple melody involving a limited set of notes to highly complex musical structures, often including a great deal of repetition of musical subphrases, such as Great Responsories and Offertories of Gregorian chant. Chant may be considered speech, music, or a heightened or stylized form of speech. In the later Middle Ages some religious chant evolved into song (forming one of the roots of later Western music)., An acoustic guitar is a guitar that produces sound acousticallyby transmitting the vibration of the strings to the airas opposed to relying on electronic amplification (see electric guitar). The sound waves from the strings of an acoustic guitar resonate through the guitar's body, creating sound. This typically involves the use of a sound board and a sound box to strengthen the vibrations of the strings., The harmonica, also known as a French harp or mouth organ, is a free reed wind instrument used worldwide in many musical genres, notably in blues, American folk music, classical music, jazz, country, and rock and roll. There are many types of harmonica, including diatonic, chromatic, tremolo, octave, orchestral, and bass versions. A harmonica is played by using the mouth (lips and tongue) to direct air into or out of one or more holes along a mouthpiece. Behind each hole is a chamber containing at least one reed. A harmonica reed is a flat elongated spring typically made of brass, stainless steel, or bronze, which is secured at one end over a slot that serves as an airway. When the free end is made to vibrate by the player's air, it alternately blocks and unblocks the airway to produce sound., Country music is a genre of United States popular music that originated in the southern United States in the 1920s. It takes its roots from the southeastern genre of United States, such as folk music (especially Appalachian folk music), and blues music. Blues modes have been used extensively throughout its recorded history. Country music often consists of ballads and dance tunes with generally simple forms and harmonies accompanied by mostly string instruments such as banjos, electric and acoustic guitars, dobros and fiddles as well as harmonicas. According to Lindsey Starnes, the term "country music" gained popularity in the 1940s in preference to the earlier term "hillbilly music"; it came to encompass Western music, which evolved parallel to hillbilly music from similar roots, in the mid-20th century. The term "country music" is used today to describe many styles and subgenres. The origins of country music are the folk music of working-class Americans, who blended popular songs, Irish and Celtic fiddle tunes, traditional English ballads, and cowboy songs, and various musical traditions from European immigrant communities. In 2009 country music was the most listened to rush hour radio genre during the evening commute, and second most popular in the morning commute in the United States., A mouth organ is a generic term for free reed aerophone with one or more air chambers fitted with a free reed., Blues is a genre and musical form originated by African Americans in the Deep South of the United States around the end of the 19th century. The genre developed from roots in African musical traditions, African-American work songs and European-American folk music. Blues incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads. The blues form, ubiquitous in jazz, rhythm and blues and rock and roll, is characterized by the call-and-response pattern, the blues scale and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds or fifths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove., The word Dobro is, in popular usage, the generic term for a wood-bodied, single cone resonator guitar. It is also an American brand of resonator guitar, currently owned by the Gibson Guitar Corporation. The Dobro was originally made by the Dopyera brothers when they formed the Dobro Manufacturing Company. Their design, with a single inverted resonator, was introduced in competition to the patented Tricone and biscuit designs produced by the National String Instrument Corporation. The Dobro name appeared on other instruments, notably electric lap steel guitars and solid body electric guitars and on other resonator instruments such as Safari resonator mandolins., The banjo is a four-, five- or six-stringed instrument with a thin membrane stretched over a frame or cavity as a resonator, called the head. The membrane, or head, is typically made of plastic, although animal skin is still occasionally but rarely used, and the frame is typically circular. Early forms of the instrument were fashioned by Africans in America, adapted from African instruments of similar design., Rhythm and blues, often abbreviated as R&B or RnB, is a genre of popular African-American music that originated in the 1940s. The term was originally used by record companies to describe recordings marketed predominantly to urban African Americans, at a time when "urbane, rocking, jazz based music with a heavy, insistent beat" was becoming more popular.
In the commercial rhythm and blues music typical of the 1950s through the 1970s, the bands usually consisted of piano, one or two guitars, bass, drums, saxophone, and sometimes background vocalists. R&B lyrical themes often encapsulate the African-American experience of pain and the quest for freedom and joy. Lyrics focus heavily on the themes of triumphs and failures in terms of relationships, freedom, economics, aspirations, and sex., DeFord Bailey ( December 14 , 1899 -- July 2 , 1982 ) was an American country music and blues star from the 1920s until 1941 . Bailey was both the first performer to be introduced as playing on the Grand Ole Opry and also the first African - American performer on the show .
