Q: Context: African-American music is an umbrella term covering a diverse range of musics and musical genres largely developed by African Americans. Their origins are in musical forms that arose out of the historical condition of slavery that characterized the lives of African Americans prior to the American Civil War., Fritz Weiss ( Czech : Bedich Weiss ) ( 28 September 1919 - 28 September 1944 ) was a jazz musician and arranger , active in the first half of the 20th century . He was an organizer of jazz performances and an important participant in the musical life of the Theresienstadt concentration camp . Weiss was one of the victims of the Holocaust ., The Jazz Age was a period in the 1920s, ending with the Great Depression, in which jazz music and dance styles became popular, mainly in the United States, but also in Britain, France and elsewhere. Jazz originated in New Orleans as a fusion of African and European music and played a significant part in wider cultural changes in this period, and its influence on pop culture continued long afterwards. The Jazz Age is often referred to in conjunction with the Roaring Twenties., 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., West Africa, also called Western Africa and the West of Africa, is the westernmost subregion of Africa. West Africa has been defined as including 18 countries: Benin, Burkina Faso, the island nation of Cape Verde, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Mali, Mauritania, Niger, Nigeria, the island of Saint Helena, Senegal, Sierra Leone, São Tomé and Príncipe and Togo., Improvisation is broad term referring to the process of devising an atypical method of solving a problem due to lack of time or resources. In a technical context, this can mean adapting a device for some use other than that which it was designed for, or building a device from unusual components in an ad-hoc fashion. Improvisation, within the context of performing arts, is a very spontaneous performance without specific or scripted preparation. The skills of improvisation can apply to many different faculties, across all artistic, scientific, physical, cognitive, academic, and non-academic disciplines., Terezín is a former military fortress composed of citadel and adjacent walled garrison town of Litomice District, in the Ústí nad Labem Region of the Czech Republic., Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km² (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two "de facto" independent states with limited or no recognition., Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries. Since the 1920s jazz age, jazz has become recognized as a major form of musical expression. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms and improvisation. Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience and styles to the art form as well. Intellectuals around the world have hailed jazz as "one of America's original art forms"., A ghetto is a part of a city in which members of a minority group live, especially because of social, legal, or economic pressure. The term was originally used in Venice to describe the part of the city to which Jews were restricted and segregated. The term has been applied in various contexts., Ragtime  also spelled rag-time or rag time  is a musical genre that enjoyed its peak popularity between 1895 and 1918. Its cardinal trait is its syncopated, or "ragged", rhythm. The genre has its origins in African-American communities like St. Louis years before being published as popular sheet music for piano. Ernest Hogan (18651909) was a pioneer of ragtime music and was the first to compose ragtime into sheet music. The composition was called "LA Pas Ma LA" and it was released in 1895. Hogan has also been credited for coining the term "ragtime". The term is actually derived from his hometown "Shake Rag" in Bowling Green, Kentucky. Ben Harney, who is also a Kentucky native has often been credited for introducing the music to the mainstream public. His first ragtime composition "You've been a good old wagon but you done broke" helped popularize the musical genre. The composition was published in 1895 but released in 1896. Ragtime was also a modification of the march made popular by John Philip Sousa, with additional polyrhythms coming from African music. The ragtime composer Scott Joplin ("ca." 18681917) became famous through the publication of the "Maple Leaf Rag" (1899) and a string of ragtime hits such as "The Entertainer" (1902), although he was later forgotten by all but a small, dedicated community of ragtime aficionados until the major ragtime revival in the early 1970s. For at least 12 years after its publication, "Maple Leaf Rag" heavily influenced subsequent ragtime composers with its melody lines, harmonic progressions or metric patterns., Theresienstadt concentration camp, also referred to as Theresienstadt ghetto, was a concentration camp established by the SS during World War II in the garrison city of Terezín, located in German-occupied Czechoslovakia., Subject: fritz weiss, Relation: country_of_citizenship, Options: (A) academic (B) american (C) benin (D) burkina faso (E) czech republic (F) czechoslovakia (G) earth (H) france (I) ghana (J) guinea (K) madagascar (L) mauritania (M) niger (N) senegal (O) venice

Q: Context: Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted and low-tuned guitars, played with techniques such as palm muting and tremolo picking, deep growling vocals and screams, aggressive, powerful drumming featuring double kick or blast beat techniques, minor keys or atonality, abrupt tempo, key, and time signature changes and chromatic chord progressions. The lyrical themes of death metal may invoke slasher film-stylized violence, religion (sometimes Satanism), occultism, Lovecraftian horror, nature, mysticism, mythology, philosophy, science fiction, and politics, and they may describe extreme acts, including mutilation, dissection, torture, rape, cannibalism, and necrophilia., Melodic death metal (also referred to as melodeath or MDM) is a subgenre death metal that employs highly melodic guitar riffs, often borrowing from traditional heavy metal. The style originated and developed in Sweden (pioneered by At the Gates, Dark Tranquillity and In Flames) and the United Kingdom (pioneered by Carcass) during the early and mid-1990s.

Q: Context: Helsinki City Transport or HKL (Finnish: "Helsingin kaupungin liikennelaitos", Swedish: "Helsingfors stads trafikverk", abbreviated "HST") is the official city-owned public transport company in Helsinki, Finland. It operates the Helsinki metro, Helsinki tram and ferry boat traffic. Its bus operations were merged with another city-owned company, Suomen Turistiauto, to form a new bus company called Helsingin Bussiliikenne. Until the beginning January 2000, HKL was responsible for planning and organising all public transport in Helsinki. After that date Helsingin seudun liikenne (HSL) took over these responsibilities., Saint Petersburg is Russia's second-largest city after Moscow, with five million inhabitants in 2012, and an important Russian port on the Baltic Sea. It is politically incorporated as a federal subject (a federal city). Situated on the Neva River, at the head of the Gulf of Finland on the Baltic Sea, it was founded by Tsar Peter the Great on May . In 1914, the name was changed from Saint Petersburg to Petrograd, in 1924 to Leningrad, and in 1991 back to Saint Petersburg.

Small boats are typically found on inland waterways (e.g., rivers and lakes) or in protected coastal areas. However, boats such as the whaleboat were designed for operation from a ship in an offshore environment. In naval terms, a boat is a vessel small enough to be carried aboard another vessel (a ship). Another less restrictive definition is a vessel that can be lifted out of the water. Some definitions do not make a distinction in size, as bulk freighters long on the Great Lakes are called oreboats. For reasons of naval tradition, submarines are usually referred to as 'boats' rather than 'ships', regardless of their size and shape. Ships are generally distinguished from boats based on their larger size, shape and cargo or passenger capacity. , The Helsinki tram network forms part of the Helsinki public transport system organised by Helsinki Regional Transport Authority and operated by Helsinki City Transport ( Finnish : Helsingin kaupungin liikenne , Swedish : Helsingfors stads trafikverk ) in the Finnish capital city of Helsinki .
