Background: The son of well-known surfer Jeff Johnson, Jack was born and raised on the North Shore of Oahu, Hawaii. He began to learn how to surf at the age of five. At seventeen he became the youngest invitee to make the finals of the Pipeline Masters, one of surfing's most prestigious surfing events, on Oahu's North Shore. One week later, however, his stint as a professional surfer ended when he suffered a surfing accident at the Pipeline that put more than 150 stitches in his forehead and removed a few of his teeth; this later became the inspiration for the song "Drink the Water".
Context: In 2008, Johnson and his wife Kim created the Johnson Ohana Charitable Foundation, a non-profit public charity supporting environmental, art, and music education worldwide. Jack and Kim Johnson also founded the Kokua Hawaii Foundation in 2003. Johnson and his family work hard every year at festivals and concerts alike, to raise money for causes they feel are most important. Johnson recorded a cover of John Lennon's "Imagine" for the 2007 benefit album Instant Karma: The Amnesty International Campaign to Save Darfur, which was also included on the 2009 benefit album Rhythms del Mundo Classics. In talking about Johnson and his career choices, Rolling Stone wrote: "It is a typically generous move from Johnson, who has used his multi-platinum success to support causes he cares about." Although the Johnson Ohana Charitable Foundation is a non-profit organization that "focuses on environmental, arts and music education", it has raised more than $750,000 from 2009 to 2010 to give away. Johnson was in Osaka, Japan on his To the Sea 2010 World Tour at the time of the 2011 Tohoku earthquake and tsunami in northern Japan. He was in a hotel with his family when it struck. After having to postpone the rest of his tour, he donated $50,000 to GlobalGiving's Japan Earthquake and Tsunami Relief Fund.  Johnson's Ohana Charitable Foundation has also supported Little Kids Rock, a national nonprofit that works to restore and revitalize music education in disadvantaged U.S. public schools. He also decorated a guitar for Little Kids Rock to auction to raise funds for its program.  On September 22, 2012, he donated his time to play a few songs at Farm Aid 2012 in Hershey, PA. Later in 2012, Jack donated $50,000 for Hurricane Sandy relief and added links on his website for others to donate:

Question:
Hattie McDaniel (June 10, 1895 - October 26, 1952) was an American stage actress, professional singer-songwriter, and comedian. She is best known for her role as "Mammy" in Gone with the Wind (1939), for which she won the Academy Award for Best Supporting Actress, the first Academy Award won by an African American entertainer. In addition to acting in many films, McDaniel was a radio performer and television star; she was the first black woman to sing on radio in the United States. She appeared in over 300 films, although she received screen credits for only 80 or so.
The whereabouts of McDaniel's Oscar are currently unknown. In 1992, Jet magazine reported that Howard University could not find it and alleged that it had disappeared during protests in the 1960s. In 1998, Howard University stated that it could find no written record of the Oscar having arrived at Howard. In 2007, an article in the Huffington Post repeated rumors that the Oscar had been cast into the Potomac River by angry civil rights protesters in the 1960s. The assertion reappeared in the Huffington Post under the same byline in 2009.  In 2010, Mo'Nique, the winner of the Academy Award for Best Supporting Actress, wearing a blue dress and gardenias in her hair, as McDaniel had at the ceremony in 1940, in her acceptance speech thanked McDaniel "for enduring all that she had to so that I would not have to". Her speech revived interest in the whereabouts of McDaniel's plaque. In 2011, J. Freedom duLac reported in the Washington Post that the plaque had disappeared in the 1960s.  In November 2011, W. B. Carter, of the George Washington University Law School, published the results of her year-and-a-half-long investigation into the Oscar's fate. Carter rejected claims that students had stolen the Oscar (and thrown it in the Potomac River) as wild speculation or fabrication that traded on long-perpetuated stereotypes of blacks. She questioned the sourcing of the Huffington Post stories. Instead, she argued that the Oscar was likely returned to Howard University's Channing Pollack Theater Collection between the spring of 1971 and the summer of 1973 or had possibly been boxed and stored in the drama department at that time. The reason for its removal, she argued, was not civil rights unrest but rather efforts to make room for a new generation of black performers. If neither the Oscar nor any paper trail of its ultimate destiny can be found at Howard today, she suggested, inadequate storage or record-keeping in a time of financial constraints and national turbulence may be blamed. She also suggested that a new generation of caretakers may have failed to realize the historic significance of the 5 1/2" x 6" plaque.

Problem: Background: Dennis Wayne Johnson (September 18, 1954 - February 22, 2007), nicknamed "DJ", was an American professional basketball player for the National Basketball Association's (NBA) Seattle SuperSonics, Phoenix Suns and Boston Celtics and coach of the Los Angeles Clippers. He was an alumnus of Dominguez High School, Los Angeles Harbor College and Pepperdine University. A prototypical late bloomer, Johnson overcame early struggles and had a successful NBA playing career. Drafted 29th overall in 1976 by the Seattle SuperSonics
Context: Dennis Wayne Johnson was born the eighth of sixteen children, to a social worker and a bricklayer who lived in Compton, California, a suburb of Los Angeles. Originally a baseball fan and a Little Leaguer, Johnson learned basketball from his father, but seemed to have neither the size nor the talent to compete with his peers: as a teenager at Dominguez High School, Johnson measured just 5'9" and played only "a minute or two each game". After high school, he worked several odd jobs, including a $2.75-per-hour job as a forklift driver, and played with his brothers in summer league games after work. During this period, Johnson grew to a height of 6'3", and developed what some later described as "rocket launcher legs", which enabled him to jump high to grab rebounds against taller opponents.  Jim White, the coach at Los Angeles Harbor College, had watched Johnson play street basketball; feeling that Johnson excelled in defense, White asked him to enroll. Johnson gave up his jobs and developed into a promising young guard, averaging 18.3 points and 12.0 rebounds per game and leading Harbor to a college junior state title. However, the young guard lacked discipline, often clashed with White and was thrown off the team three times in two years.  At the end of his junior college career, two universities offered Johnson scholarships: Azusa Pacific University and Pepperdine University. Johnson chose the latter, and in his only year there, he averaged 15.7 points, 5.8 rebounds and 3.3 assists per game, and developed a reputation for tough defense. After that year, Johnson made himself eligible for the 1976 NBA draft, but was skeptical that any team would take him. NBA teams were wary of drafting a player with character issues, and Johnson was known to be a troublemaker.
Question: Did he win any award ?
Answer:
young guard lacked discipline, often clashed with White and was thrown off the team three times in two years.
