Problem: De La Soul is an American hip hop trio formed in 1987 on Long Island, New York. The group is best known for their eclectic sampling, quirky lyrics, and their contributions to the evolution of the jazz rap and alternative hip hop subgenres. The members are Posdnuos, Trugoy the Dove and Maseo. The three formed the group in high school and caught the attention of producer Prince Paul with a demo tape of the song "Plug Tunin'".

The group's third studio release, 1993's Buhloone Mindstate, saw the group evolve a new sound as they continued to grow stylistically and musically. There were several moments on the album which proved the band had matured. "I Be Blowin'" was a departure as the track was an instrumental featuring saxophone playing by Maceo Parker. The introspective "I Am I Be" showed De La Soul at their most self-referential to date with subject matter about Pos' daughter Ayana Monet as well as his grandmother. "Long Island Wildin'" was a collaboration with Japanese hip hop artists Kan Takagi (Major Force) and trio Scha Dara Parr (SDP). The album's first single, "Breakadawn", used a sample of Michael Jackson's "I Can't Help It" and Smokey Robinson's "Quiet Storm". De La Soul collaborated for the first time with Gang Starr's Guru on "Patti Dooke", female MC Shortie No Mas, a cousin of Posdnuos, was prominent on many tracks on the album, showcased particularly "In The Woods". The album ended with an old school Biz Markie collaboration called "Stone Age". Missing from vocal duties is Mase, whose voice can only be heard on "Area" in a break near the end of the track. Also rarely featured is his scratching which was heard often on previous albums, with only "In the Woods" showcasing his talent in that area. The album was a critical success, but it was the biggest commercial failure for the group at the time of its release. Many publications, such as Rolling Stone, have listed this album as one of the best hip hop albums of all time.  In 1994, 500 copies of a promotional EP called Clear Lake Audiotorium were released on clear vinyl and CD. The 6 track EP contained edited versions of tracks off of Buhloone Mindstate but also featured the tracks "Sh.Fe.MC's" (Shocking Female MC's) which was a collaboration with A Tribe Called Quest, and Stix & Stonz which featured old-school hip hop artists Grandmaster Caz, Tito of Fearless Four, Whipper Whip, LA Sunshine and Superstar. The EP was widely bootlegged afterwards.  Stakes Is High (1996) was the first album not produced by Prince Paul, with overall production credits given solely to the trio. Although it was met with poor sales, it has been critically lauded for its music, lyricism, and its overall message concerning the artistic decline rap music began to face in the mid-90s. The title track and first single, produced by J Dilla, was not a hit, but the album's second single, "Itzsoweezee (HOT)", with only Dave on vocals, did fare better due to its creative music video. The album spawned a third single "4 More", featuring Zhane which peaked at #52 in the UK. The album did provide a launching pad for future star rapper and actor Mos Def, who appeared on the track "Big Brother Beat". The album also featured collaborations with Common, Truth Enola, and the Jazzyfatnastees.

Problem: 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.

Pistorius has been the subject of criticism because of claims that his artificial limbs give him an advantage over runners with natural ankles and feet. He runs with J-shaped carbon-fibre prosthetics called the "Flex-Foot Cheetah" developed by biomedical engineer Van Phillips and manufactured by Ossur.  On 26 March 2007, the IAAF amended its competition rules to include a ban on the use of "any technical device that incorporates springs, wheels or any other element that provides a user with an advantage over another athlete not using such a device". The IAAF stated that the amendment was not specifically aimed at Pistorius. To decide whether he was running with an unfair advantage, the IAAF monitored his track performances using high-definition cameras to film his race against Italian club runners in Rome on 13 July, and his 400 metres in Sheffield on 15 July 2007, at which he placed last.  In November 2007, Pistorius was invited to take part in a series of scientific tests at the Cologne Sports University under the guidance of Professor of Biomechanics Dr Peter Bruggemann in conjunction with Elio Locatelli, who was responsible with the IAAF of all technical issues. After two days of tests, Bruggemann reported on his findings on behalf of the IAAF. The report claimed that Pistorius's limbs used 25% less energy than runners with complete natural legs to run at the same speed, and that they led to less vertical motion combined with 30% less mechanical work for lifting the body. In December, Bruggemann told Die Welt newspaper that Pistorius "has considerable advantages over athletes without prosthetic limbs who were tested by us. It was more than just a few percentage points. I did not expect it to be so clear." Based on these findings, on 14 January 2008, the IAAF ruled Pistorius's prostheses ineligible for use in competitions conducted under the IAAF rules, including the 2008 Summer Olympics. Pistorius called the decision "premature and highly subjective" and pledged to continue fighting for his dream. His manager Peet van Zyl said his appeal would be based on advice from United States experts who had said that the report "did not take enough variables into consideration".  Pistorius subsequently appealed against the adverse decision to the Court of Arbitration for Sport (CAS) in Lausanne, Switzerland, and appeared before the tribunal at the end of April 2008. After a two-day hearing, on 16 May 2008, the Court of Arbitration for Sport upheld Pistorius's appeal and the IAAF council decision was revoked with immediate effect. The CAS panel unanimously determined that Dr Bruggemann tested Pistorius's biomechanics only at full-speed when he was running in a straight line (unlike a real 400-metre race); that the report did not consider the disadvantages that Pistorius suffers at the start and acceleration phases of the race; and that overall there was no evidence that he had any net advantage over non-disabled athletes. In response to the announcement, Pistorius said: "My focus throughout this appeal has been to ensure that disabled athletes be given the chance to compete and compete fairly with non-disabled athletes. I look forward to continuing my quest to qualify for the Olympics."
