Question: Information: - The xylophone (from the Greek words "xylon", "wood" + "phn", "sound, voice", meaning "wooden sound") is a musical instrument in the percussion family that consists of wooden bars struck by mallets. Each bar is an idiophone tuned to a pitch of a musical scale, whether pentatonic or heptatonic in the case of many African and Asian instruments, diatonic in many western children's instruments, or chromatic for orchestral use. - An orchestra is a large instrumental ensemble typical of classical music, which features string instruments such as violin, viola, cello and double bass, as well as brass, woodwinds, and percussion instruments, grouped in sections. Other instruments such as the piano and celesta may sometimes appear in a fifth keyboard section or may stand alone, as may the concert harp and, for performances of some modern compositions, electronic instruments. - The luntang is a type of Philippine xylophone of the Maguindanaon people , strung vertically , with five horizontal logs hung in ascending order arranged by pitch . The Maguindanaon refer to this instrument as a luntang while the Yakan call it a kwintangan kayo . The cylindrical logs are beaten at the edge to create sounds and can be played either solo or with two people on either side . Among the Maguindanaon , the luntang is used only for self - entertainment purposes , to keep farmers awake while at the same time keeping the birds away from the fields . Commonly used for long distance communication some times ago by the Maguindanaon , the Yakan have taken its use a step further : using it for social interactions between sexes as well . Given the information, choose the subject and object entities that have the relation of 'subclass of'.
Answer: luntang , idiophone
[Q]: Information: - Klaus Friedrich Roth ( 29 October 1925 -- 10 November 2015 ) was a German - born British mathematician known for work on diophantine approximation , the large sieve , and irregularities of distribution . - In mathematics, a real number is a value that represents a quantity along a line. The adjective "real" in this context was introduced in the 17th century by Rene Descartes, who distinguished between real and imaginary roots of polynomials. - In mathematics, analytic number theory is a branch of number theory that uses methods from mathematical analysis to solve problems about the integers. It is often said to have begun with Peter Gustav Lejeune Dirichlet's 1837 introduction of Dirichlet "L"-functions to give the first proof of Dirichlet's theorem on arithmetic progressions. It is well known for its results on prime numbers (involving the Prime Number Theorem and Riemann zeta function) and additive number theory (such as the Goldbach conjecture and Waring's problem). Branches of analytic number theory. Analytic number theory can be split up into two major parts, divided more by the type of problems they attempt to solve than fundamental differences in technique. - The large sieve is a method (or family of methods and related ideas) in analytic number theory. - In number theory, the field of Diophantine approximation deals with the approximation of real numbers by rational numbers. It is named after Diophantus of Alexandria. - Number theory or, in older usage, arithmetic is a branch of pure mathematics devoted primarily to the study of the integers. It is sometimes called "The Queen of Mathematics" because of its foundational place in the discipline. Number theorists study prime numbers as well as the properties of objects made out of integers (e.g., rational numbers) or defined as generalizations of the integers (e.g., algebraic integers). - In mathematics, a rational number is any number that can be expressed as the quotient or fraction "p"/"q" of two integers, a numerator "p" and a non-zero denominator "q". Since "q" may be equal to1, every integer is a rational number. The set of all rational numbers, often referred to as "the rationals", is usually denoted by a boldface Q (or blackboard bold formula_1, Unicode ); it was thus denoted in 1895 by Giuseppe Peano after "quoziente", Italian for "quotient". Given the information, choose the subject and object entities that have the relation of 'field of work'.

input: Please answer the following: Information: - Andrzej Munk (16 October 1921 20 September 1961) was a Polish film director, screen writer and documentalist. He was one of the most influential artists of the post-Stalinist period in the People's Republic of Poland. His feature films "Man on the Tracks" ("Czowiek na torze", 1956), "Eroica" ("Heroism", 1958), "Bad Luck" ("Zezowate szczcie", 1960), and "Passenger" ("Pasaerka" 1963), are considered classics of the Polish Film School developed in mid-1950s. He died as a result of a car crash in Kompina in a head-on collision with a truck. - Bad Luck ( Polish : Zezowate szczcie ) is a 1960 Polish comedy film directed by Andrzej Munk . It was entered into the 1960 Cannes Film Festival . - The 13th Cannes Film Festival was held from 4 to 20 May 1960. The Palme d'Or went to the "La Dolce Vita" by Federico Fellini. The festival opened with "Ben-Hur", directed by William Wyler. - Kompina is a village in the administrative district of Gmina Nieborow, within owicz County, od Voivodeship, in central Poland. It lies approximately east of owicz and north-east of the regional capital od. - The Cannes Festival (French: Festival de Cannes), named until 2002 as the International Film Festival ("Festival international du film") and known in English as the Cannes Film Festival, is an annual film festival held in Cannes, France, which previews new films of all genres, including documentaries, from all around the world. Founded in 1946, the invitation-only festival is held annually (usually in May) at the Palais des Festivals et des Congres. Given the information, choose the subject and object entities that have the relation of 'country of origin'.
