Approximately 55% of the lines in the world are this gauge. All high-speed rail lines (except those in Russia, Uzbekistan, and Finland) are standard gauge. The distance between the inside edges of the rails is defined to be (except in the United States, where it is still defined in Imperial and US customary units as ). It is also called the UIC gauge or UIC track gauge, the European gauge in the EU and Russia, or uniform gauge in Queensland, Australia., The Semmering railway ( German : Semmeringbahn ) in Austria , which starts at Gloggnitz and leads over the Semmering to Mürzzuschlag was the first mountain railway in Europe built with a standard gauge track .

Renowned as the "Father of Railways", the Victorians considered him a great example of diligent application and thirst for improvement, with self-help advocate Samuel Smiles particularly praising his achievements. His rail gauge of , sometimes called "Stephenson gauge", is the standard gauge by name and by convention for most of the world's railways., The Mürz is a river in Austria. It begins north of the Schneealpe in Lower Austria, flows into Styria, and meets the Mur River after 98 km in Bruck an der Mur. Its headwaters end at Mürzzuschlag. Along its course are the tracks of the Southern Railway as well as the Semmering Highway., Lower Austria (; ) is the northeasternmost state of the nine states in Austria. The capital of Lower Austria since 1986 is Sankt Pölten, the most recently designated capital town in Austria.

In many languages, the letter ö, or the O modified with what is known as an "umlaut mark", is used to denote the non-close front rounded vowels or . In languages without such vowels, the character is known as an "O with diaeresis" and denotes a syllable break, wherein its pronunciation remains an unmodified ., High-speed rail is a type of rail transport that operates significantly faster than traditional rail traffic, using an integrated system of specialized rolling stock and dedicated tracks. While there is no single standard that applies worldwide, new lines in excess of and existing lines in excess of are widely considered to be high-speed, with some extending the definition to include lower speeds in areas for which these speeds still represent significant improvements. The first such system began operations in Japan in 1964 and was widely known as the bullet train. High-speed trains normally operate on standard gauge tracks of continuously welded rail on grade-separated right-of-way that incorporates a large turning radius in its design., "For the town of the same name, see Semmering, Austria.", Vienna is the capital and largest city of Austria and one of the nine states of Austria. Vienna is Austria's primary city, with a population of about 1.8 million (2.6 million within the metropolitan area, nearly one third of Austria's population), and its cultural, economic, and political centre. It is the 7th-largest city by population within city limits in the European Union.

Q: Context: A string band is an old-time music or jazz ensemble made up mainly or solely of string instruments. String bands were popular in the 1920s and 1930s, and are among the forerunners of modern country music and bluegrass., The Red Fox Chasers were a string band that formed in North Carolina in 1927, and were active until around 1931. Members included vocalist and guitar player A. P. Thompson, vocalist and harmonica player Bob Cranford, vocalist and banjo player Paul Miles, and fiddler Guy Brooks., Guy Brooks was a fiddle player for the late 1920s early 1930s string band The Red Fox Chasers . He played classic old time music ., A.P. Thompson was the lead vocalist and guitar player for the late 1920s early 1930s string band The Red Fox Chasers., 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., The violin is a wooden string instrument in the violin family. It is the smallest and highest-pitched instrument in the family in regular use. Smaller violin-type instruments are known, including the violino piccolo and the kit violin, but these are virtually unused in the 2010s. The violin typically has four strings tuned in perfect fifths, and is most commonly played by drawing a bow across its strings, though it can also be played by plucking the strings with the fingers (pizzicato). Violins are important instruments in a wide variety of musical genres. They are most prominent in the Western classical tradition and in many varieties of folk music. They are also frequently used in genres of folk including country music and bluegrass music and in jazz. Electric violins are used in some forms of rock music; further, the violin has come to be played in many non-Western music cultures, including Indian music and Iranian music. The violin is sometimes informally called a fiddle, particularly in Irish traditional music and bluegrass, but this nickname is also used regardless of the type of music played on it., Folk music includes both traditional music and the genre that evolved from it during the 20th century folk revival. The term originated in the 19th century but is often applied to music that is older than that. Some types of folk music are also called world music. "Traditional folk music" has been defined in several ways: as music transmitted orally, music with unknown composers, or music performed by custom over a long period of time. It has been contrasted with commercial and classical styles., Bob Cranford was a vocalist and harmonica player for the late 1920s and early 1930s string band The Red Fox Chasers., Subject: guy brooks, Relation: occupation, Options: (A) band (B) commercial (C) drawing (D) fiddler (E) vocalist

Q: Context: Asteroids are minor planets, especially those of the inner Solar System. The larger ones have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet and was not observed to have the characteristics of an active comet. As minor planets in the outer Solar System were discovered and found to have volatile-based surfaces that resemble those of comets, they were often distinguished from asteroids of the asteroid belt. In this article, the term "asteroid" refers to the minor planets of the inner Solar System including those co-orbital with Jupiter., A near-Earth object (NEO) is any small Solar System body whose orbit brings it into proximity with Earth. By definition, a solar system body is a NEO if its closest approach to the Sun (perihelion) is less than 1.3 astronomical unit (AU). NEOs include more than fourteen thousand near-Earth asteroids (NEAs), more than one hundred near-Earth comets (NECs), and a number of solar-orbiting spacecraft and meteoroids, large enough to be tracked in space before striking the Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of the Earth. NEOs have become of increased interest since the 1980s because of increased awareness of the potential danger some of the asteroids or comets pose, and mitigations are being researched. In January 2016, NASA announced the Planetary Defense Coordination Office to track NEOs larger than 30 to 50 meters in diameter and coordinate an effective threat response and mitigation effort., The Apollo asteroids are a group of near-Earth asteroids named after 1862 Apollo, discovered by German astronomer Karl Reinmuth in the 1930s. They are Earth crossing asteroids that have an orbital semi-major axis greater than that of the Earth (> 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU)., 5731 Zeus ( 1988 VP4 ) is an Apollo asteroid and near - Earth object discovered on November 4 , 1988 by Carolyn Shoemaker at Palomar Observatory . Based on its observed brightness and assumed albedo it is estimated to have a diameter between 2.1 and 4.7 km., Subject: 5731 zeus, Relation: minor_planet_group, Options: (A) apollo asteroids (B) asteroid belt
