PROBLEM: Context: Kojo Adeyemo Annan ( born 25 July 1973 in Geneva , Switzerland ) is the only son of former UN Secretary - General Kofi Annan ., Nelson Rolihlahla Mandela (18 July 1918  5 December 2013) was a South African anti-apartheid revolutionary, politician, and philanthropist, who served as President of South Africa from 1994 to 1999. He was the country's first black head of state and the first elected in a fully representative democratic election. His government focused on dismantling the legacy of apartheid by tackling institutionalised racism and fostering racial reconciliation. Ideologically an African nationalist and socialist, he served as President of the African National Congress (ANC) party from 1991 to 1997.
A Xhosa, Mandela was born in Mvezo to the Thembu royal family. He studied law at the University of Fort Hare and the University of the Witwatersrand before working as a lawyer in Johannesburg. There he became involved in anti-colonial and African nationalist politics, joining the ANC in 1943 and co-founding its Youth League in 1944. After the National Party's white-only government established apartheida system of racial segregation that privileged whiteshe and the ANC committed themselves to its overthrow. Mandela was appointed President of the ANC's Transvaal branch, rising to prominence for his involvement in the 1952 Defiance Campaign and the 1955 Congress of the People. He was repeatedly arrested for seditious activities and was unsuccessfully prosecuted in the 1956 Treason Trial. Influenced by Marxism, he secretly joined the South African Communist Party (SACP). Although initially committed to non-violent protest, in association with the SACP he co-founded the militant Umkhonto we Sizwe in 1961 and led a sabotage campaign against the government. In 1962, he was arrested for conspiring to overthrow the state and sentenced to life imprisonment in the Rivonia Trial.
Mandela served 27 years in prison, initially on Robben Island, and later in Pollsmoor Prison and Victor Verster Prison. Amid growing domestic and international pressure, and with fears of a racial civil war, President F. W. de Klerk released him in 1990. Mandela and de Klerk negotiated an end to apartheid and organised the 1994 multiracial general election in which Mandela led the ANC to victory and became President. Leading a broad coalition government which promulgated a new constitution, Mandela emphasised reconciliation between the country's racial groups and created the Truth and Reconciliation Commission to investigate past human rights abuses. Economically, Mandela's administration retained its predecessor's liberal framework despite his own socialist beliefs, also introducing measures to encourage land reform, combat poverty, and expand healthcare services. Internationally, he acted as mediator in the Pan Am Flight 103 bombing trial and served as Secretary-General of the Non-Aligned Movement from 1998 to 1999. He declined a second presidential term and in 1999 was succeeded by his deputy, Thabo Mbeki. Mandela became an elder statesman and focused on combating poverty and HIV/AIDS through the charitable Nelson Mandela Foundation.
Mandela was a controversial figure for much of his life. Although critics on the right denounced him as a communist terrorist and those on the radical left deemed him too eager to negotiate and reconcile with apartheid's supporters, he gained international acclaim for his activism. Widely regarded as an icon of democracy and social justice, he received more than 250 honoursincluding the Nobel Peace Prizeand became the subject of a cult of personality.

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

They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single nontechnical user. These computers were a distinct market segment that typically cost much less than business, scientific or engineering-oriented computers of the time such as the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporaneous business computers.

ABC 80 normally used a dedicated ( included ) tape recorder for program and data storage , but could also be expanded to handle disk drives ( and many other peripherals ) . Some sound effects could be produced by a Texas Instruments SN76477 sound chip which was connected to an 8 - bit output port , but there was no way to control the chip 's features in any detail , so sound was limited to 96 fixed sounds . The monitor was a black and white TV set modified for the purpose ( an obvious choice since Luxor also made TVs ) . The computer had excellent I / O response times , something that was discovered when trying to upgrade to personal computers . The solution was to use a microcontroller that communicated with a PC . The main unit had a reset button as well . ABC 80 was also manufactured on license as BRG ABC80 by Budapesti Rádiótechnikai Gyár in Hungary . It used the same keyboard , but the case was metal instead of plastic ., Subject: abc 80, Relation: manufacturer, Options: (A) denmark (B) estonia (C) germany (D) ibm (E) luxor ab (F) nokia (G) seat (H) united kingdom
