Problem: Background: Pieter Willem Botha, DMS (Afrikaans pronunciation: ['pit@r 'v@l@m 'bU@ta]; 12 January 1916 - 31 October 2006), commonly known as "P. W." and Die Groot Krokodil (Afrikaans for "The Big Crocodile"), was the leader of South Africa from 1978 to 1989, serving as the last Prime Minister from 1978 to 1984 and the first executive State President from 1984 to 1989. First elected to Parliament in 1948, Botha was an outspoken opponent of majority rule and international communism. However, his administration did make concessions towards political reform, whereas internal unrest saw widespread human rights abuses at the hands of the government. Botha resigned the leadership of the ruling National Party in February 1989 after suffering a stroke and six months later was coerced to leave the presidency as well.
Context: In superficial ways, Botha's application of the apartheid system was less repressive than that of his predecessors. He legalised interracial marriage and miscegenation, both completely banned since the late 1940s. The constitutional prohibition on multiracial political parties was lifted. He also relaxed the Group Areas Act, which barred non-whites from living in certain areas. In 1988, a new law created "Open Group Areas" or racially mixed neighborhoods. But these neighborhoods had to receive a Government permit, and had to have the support of the local Whites immediately concerned, and had to be a high class neighborhood in the major cities typically in order to receive the permit. In 1983, the above constitutional reforms granted limited political rights to Coloureds and Indians. Botha also became the first South African government leader to authorise contacts with Nelson Mandela, the imprisoned leader of the African National Congress. However, in the face of rising discontent and violence, Botha refused to cede political power to blacks and imposed greater security measures against anti-apartheid activists. Botha also refused to negotiate with the ANC.  In 1985, Botha delivered the Rubicon speech which was a policy address in which he refused to give in to demands by the black population, including the release of Mandela. Botha's defiance of international opinion further isolated South Africa, leading to economic sanctions and a rapid decline in the value of the rand. The following year, when the US introduced the Comprehensive Anti-Apartheid Act, Botha declared a nationwide state of emergency. He is famously quoted during this time as saying, "This uprising will bring out the beast in us".  As economic and diplomatic actions against South Africa increased, civil unrest spread amongst the black population, supported by the ANC and neighbouring black-majority governments. On 16 May 1986, Botha publicly warned neighbouring states against engaging in "unsolicited interference" in South Africa's affairs. Four days later, Botha ordered air strikes against selected targets in Lusaka, Harare, and Gaborone, including the offices of exiled ANC activists. Botha charged that these raids were just a "first installment" and showed that "South Africa has the capacity and the will to break the [African National Congress]."  In spite of the concessions made by Botha, the apartheid years under his leadership were by far the most brutal. Thousands were detained without trial during Botha's presidency, while others were tortured and killed. The Truth and Reconciliation Commission found Botha responsible for gross violations of human rights. He was also found to have directly authorised 'unlawful activity which included killing.' However, Botha refused to apologise for apartheid. In a 2006 interview to mark his 90th birthday, he suggested that he had no regrets about the way he had run the country. He denied, however, that he had ever considered black South Africans to be in any way inferior to whites, but conceded that "some" whites did hold that view. He also claimed that the apartheid policies were inherited from the British colonial administration in the Cape and Natal Province, implying that he considered them something he and his government had followed by default.
Question: How many years was he active in fighting segregation
Answer: 

Background: Cudi was born Scott Ramon Seguro Mescudi on January 30, 1984, in Cleveland, Ohio, and grew up in Shaker Heights and Solon. He is the youngest of four children, with two brothers, Domingo and Dean, and a sister, Maisha. His mother, Elsie Harriet (Banks), is a middle-school choir teacher at Roxboro Middle School in Cleveland Heights, Ohio. His father, Lindberg Styles Mescudi, was a house painter, substitute teacher and World War II Air Force veteran.
Context: Kid Cudi's musical style has been described as "an atmospheric take on melodic rap, with a dollop of charming, off-key singing". He has also been called "introspective, with the ability to lay his insecurities on record and expose his fallibility." In 2015, Kris Ex of Billboard, wrote "he's always been an emotional artist, dealing with expansive and nebulous feelings in acute and often destructive ways." Kid Cudi's sound is what inspired and led Kanye West to create his cathartic 808s & Heartbreak (2008), with West later stating that he and Cudi were "the originators of the style, kinda like what Alexander McQueen is to fashion.... Everything else is just Zara and H&M." West also complimented Cudi by saying, "His writing is just so pure and natural and important." In March 2014, Cudi talked about wanting to provide guidance for young listeners with his music: "my mission statement since day one [...] all I wanted to do was help kids not feel alone, and stop committing suicide."  In a 2013 article for The BoomBox, the author wrote: "On [A Kid Named Cudi], Cudi raps and croons over samples and interpolations of Gnarls Barkley, Paul Simon, Band of Horses, J Dilla, Nosaj Thing, N.E.R.D. and Outkast. He melded indie rock, electronica and dubstep seamlessly with hip-hop without pandering or reaching. Before Drake broke through with 2009's So Far Gone, rapping and singing over Swedish indie poppers Lykke Li and Peter Bjorn and John, Cudi tweaked with multi-genre covers and seamless transitions between singing and rapping." In a 2009 interview with HipHopDX, when speaking on his debut album Cudi stated: "Well one thing I wanted to do was combine sounds that really bring out intense moods."  Kid Cudi's music has also been described as trip hop. Furthermore, he is known for harmonizing and humming in his music, which helps formulate his signature sound. On 2011's WZRD and 2015's Speedin' Bullet 2 Heaven, Cudi incorporated the use of screamed vocals, and can be heard yodeling on his 2016 album Passion, Pain & Demon Slayin'. Throughout the years he has also incorporated elements of psychedelia, R&B, electronica, synthpop and grunge, in his music.
