The answer to the question: What is the last name of the person who took part in the 2002 documentary Amandla!: A Revolution in Four-Part Harmony? is inside the article: Following growing pressure from the anti-apartheid movement both domestically and internationally, in 1990 State President Frederik Willem de Klerk reversed the ban on the African National Congress and other anti-apartheid organisations, and announced that Mandela would shortly be released from prison. Mandela was released in February 1990. He persuaded Makeba to return to South Africa, which she did, using her French passport, on 10 June 1990. Makeba, Gillespie, Simone, and Masekela recorded and released her studio album, Eyes on Tomorrow, in 1991. It combined jazz, R&B, pop, and traditional African music, and was a hit across Africa. Makeba and Gillespie then toured the world together to promote it. In November she made a guest appearance on a US sitcom, The Cosby Show. In 1992, she starred in the film Sarafina!, which centred on students involved in the 1976 Soweto uprising. Makeba portrayed the title character's mother, Angelina, a role which The New York Times described as having been performed with "immense dignity".On 16 October 1999, Makeba was named a Goodwill Ambassador of the Food and Agriculture Organization of the United Nations.

Q: The answer to the question: What are the names of the significant personalities introduced on 6th Avenue? is inside the article: BookWars is a creative documentary which is told in an unconventional, narrative style. The film opens with the narrator (who is also the film's director) driving out West along a desert highway, relating to the audience his previous experiences as a streetside bookseller in New York City. The entire documentary – including the central events involving his experiences among the street booksellers in New York – is thus "told" as a long conversation. The narrator describes his post-graduation years in New York, and how he ended up at one point virtually penniless. Driven by a desperate need to pay the rent, he resorts to wheeling his own books out to the street to try to sell them. He reveals that he was not only successful in making a significant amount of cash on that first day, but he has also met a variety of interesting and strange characters of the streets of New York – including other street booksellers. A motley assortment of street booksellers on West 4th street, in Greenwich Village, New York City, are first introduced. Among them: "Slick" Rick Sherman, a semi-professional magician; Al Mappo, so named because he only sells maps and atlases; Emil, who says only he "escaped", though we do not know from where; and Pete Whitney: King of the booksellers, toad collector, and collage artist. BookWars next introduces another group of street booksellers who hawk their trade on nearby 6th Avenue. Mainly black and minority individuals, they ply books and magazines in parallel fashion to the nearby West 4th street booksellers, who are primarily white. The booksellers on 6th Avenue suffer greater exposure to the law, with many claiming this to be due to racial profiling. Some of the significant personalities that are introduced on 6th Avenue include: Marvin, always wearing his trademark black hat; and Ron, from Jamaica – charismatic, streetwise and outspoken., can you guess it ?
A: Ron

The answer to the question: Whose album changed perceived notions about the number of successful singles that could be taken from one album? is inside the article: Blender described Jackson as the "late 20th century's preeminent pop icon", while The New York Times gave the opinion that he was a "musical phenomenon" and that "in the world of pop music, there is Michael Jackson and there is everybody else". Jackson changed the way the industry functioned: both as an artistic persona and as a financial, profitable entity. His attorney John Branca observed that Jackson achieved the highest royalty rate in the music industry to that point: approximately $2 (US$4.82 in 2018 dollars) for each album sold. As a result, Jackson earned record-breaking profits from compact disc sales and from the sale of copies of the documentary, The Making of Michael Jackson's Thriller, produced by Jackson and John Landis. Funded by MTV, the film sold over 350,000 copies in its first few months. In a market then driven by singles, Thriller raised the significance of albums, yet its multiple hit singles changed perceived notions as to the number of successful singles that could be taken from an individual album. The era saw the arrival of novelties like the Michael Jackson doll, that appeared in stores in May 1984 at a price of $12 (US$29 in 2018 dollars). Thriller retains a position in American culture; biographer J. Randy Taraborrelli explains, "At some point, Thriller stopped selling like a leisure item—like a magazine, a toy, tickets to a hit movie—and started selling like a household staple".At the time of the album's release, a press statement from Gil Friesen, the then President of A&M Records, read that, "The whole industry has a stake in this success". Time magazine speculated that "the fallout from Thriller has given the [music] business its best years since the heady days of 1978, when it had an estimated total domestic revenue of $4.1 billion". Time summed up Thriller's impact as a "restoration of confidence" for an industry bordering on "the ruins of punk and the chic regions of synthesizer pop". The publication described Jackson's influence at that point as, "Star of records, radio,..., can you guess it ?
