Problem: Background: Henry John Deutschendorf Jr. (December 31, 1943 - October 12, 1997), known professionally as John Denver, was an American singer-songwriter, record producer, actor, activist, and humanitarian, whose greatest commercial success was as a solo singer. After traveling and living in numerous locations while growing up in his military family, Denver began his music career with folk music groups during the late 1960s. Starting in the 1970s, he was one of the most popular acoustic artists of the decade and one of its best-selling artists. By 1974, he was firmly established as one of America's best-selling performers, and AllMusic has described Denver as "among the most beloved entertainers of his era".
Context: Denver began his recording career with a group that had started as the Chad Mitchell Trio; his distinctive voice can be heard where he sings solo on Violets of Dawn, among other songs. He recorded three albums with the Mitchell Trio, replacing Chad Mitchell himself as high tenor. The group Denver, Boise, and Johnson, which had evolved from the Mitchell Trio, released a single before he moved on to a solo career. Bill Danoff and Taffy Nivert, credited as co-writers of Denver's song "Take Me Home, Country Roads", were close friends of Denver and his family, appearing as singers and songwriters on many of Denver's albums until they formed the Starland Vocal Band in 1976. The band's albums were released on Denver's Windsong Records (later known as Windstar Records) label. Denver's solo recording contract resulted in part from the recording by Peter, Paul, and Mary of his song "Leaving on a Jet Plane", which became the sole number-1 hit single for the group. Denver recorded songs by Tom Paxton, Eric Andersen, John Prine, David Mallett, and many others in the folk scene. His record company, Windstar, is still an active record label today. Country singer John Berry considers Denver the greatest influence on his own music and has recorded Denver's hit "Annie's Song" with the original arrangement. Olivia Newton-John, an Australian singer whose across-the-board appeal to pop, MOR, and country audiences in the mid-1970s was similar to Denver's, lent her distinctive backup vocals to Denver's 1975 single "Fly Away"; she performed the song with Denver on his 1975 Rocky Mountain Christmas special. She also covered his "Take Me Home, Country Roads", and had a hit in the United Kingdom (#15 in 1973) and Japan (#6 in a belated 1976 release) with it. In 1976, Denver appeared as a guest star, along with Olivia Newton-John, who made a cameo appearance, on The Carpenters Very First Special, a one-hour TV special broadcast on the ABC television network. A highlight of the program was John singing a duet with Karen Carpenter of a medley of "Comin' Thro' the Rye" and "Good Vibrations", although the medley was never released commercially as a single or on an album.

Problem: Background: Oscar Leonard Carl Pistorius was born to Henke and Sheila Pistorius on 22 November 1986 in Sandton, Johannesburg, in what was then Transvaal Province (now Gauteng Province) of South Africa. He grew up in a Christian home and has an elder brother, Carl, and a younger sister, Aimee. Pistorius credits his mother, who died at the age of 43 when Pistorius was 15 years old, as a major influence in his life. Pistorius is a white South African with Italian ancestry from his maternal great-grandfather, who was an Italian emigrant to Kenya.
Context: Pistorius also carried the flag at the opening ceremony of the 2012 Summer Paralympics on 29 August. He entered the T44 classification men's 100 metres, 200 metres and 400 metres races, and the T42-T46 4 x 100 metres relay. In the 200-metre competition, Pistorius established a new T43 world record of 21.30 seconds in his heat on 1 September, but he was defeated in the final the next day by Alan Oliveira of Brazil. Pistorius took silver, and then created a controversy by complaining about the length of Oliveira's blades. He later apologised for the timing of his remarks, but not the content of his complaint. The IPC confirmed the length of Oliveira's blades were proportional to his body, with all the finalists measured before the race. The IPC also confirmed that Pistorius had raised the issue of blade length with it six weeks prior to the race. SASCOC issued a statement welcoming Pistorius's apology for his outburst and declared their full support for him and promised to assist him in discussions with the IPC about the issue of lengthened prosthetics after the conclusion of the Games. The IPC expressed willingness to engage with Pistorius about the issue. Australian runner Jack Swift, USA runner Jerome Singleton, and other athletes also expressed support for Pistorius's position. Pistorius won a gold medal on 5 September running the anchor leg as part of the South African 4 x 100 metres relay team. The team set a world record time of 41.78 seconds. He was unsuccessful in defending his Beijing Olympics 100-metre title when he came fourth with a season's best time of 11.17 seconds, and the race was won by Great Britain's Jonnie Peacock. On 8 September, the last full day of competition, Pistorius won gold in the T44 400 metres with a time of 46.68 seconds, breaking the Paralympic record.
