Problem: Background: Young was born in Compton, California, the first child of Theodore and Verna Young. His middle name, Romelle, is derived from his father's amateur R&B singing group, The Romells. His parents married in 1964, separated in 1968, and divorced in 1972. His mother later remarried and had three children: sons Jerome and Tyree (both deceased) and daughter Shameka.
Context: Inspired by the Grandmaster Flash song "The Adventures of Grandmaster Flash on the Wheels of Steel", he often attended a club called Eve After Dark to watch many DJs and rappers performing live. He subsequently became a DJ in the club, initially under the name "Dr. J", based on the nickname of Julius Erving, his favorite basketball player. At the club, he met aspiring rapper Antoine Carraby, later to become member DJ Yella of N.W.A. Soon afterwards he adopted the moniker Dr. Dre, a mix of previous alias Dr. J and his first name, referring to himself as the "Master of Mixology". Eve After Dark had a back room with a small four-track studio. In this studio, Dre and Yella recorded several demos. In their first recording session, they recorded a song entitled "Surgery", with the lyrics "calling Dr. Dre to surgery" serving as the chorus to the song. He later joined the musical group World Class Wreckin' Cru under the independent Kru-Cut Records in 1984. The group would become stars of the electro-hop scene that dominated early 1980s West Coast hip hop. "Surgery", which was officially released after being recorded prior to the group's official formation, would prominently feature Dr. Dre on the turntable. The record would become the group's first hit, selling 50,000 copies within the Compton area. Dr. Dre and DJ Yella also performed mixes for local radio station KDAY, boosting ratings for its afternoon rush-hour show The Traffic Jam. Dr. Dre's earliest recordings were released in 1994 on a compilation titled Concrete Roots. Stephen Thomas Erlewine of the website AllMusic described the compiled music, released "several years before Dre developed a distinctive style", as "surprisingly generic and unengaging" and "for dedicated fans only". His frequent absences from school jeopardized his position as a diver on his school's swim team. After high school, he attended Chester Adult School in Compton following his mother's demands for him to get a job or continue his education. After brief attendance at a radio broadcasting school, he relocated to the residence of his father and residence of his grandparents before returning to his mother's house. He later dropped out of Chester to focus on performing at the Eve's After Dark nightclub.

Answer: musical group

Problem: Background: Terence Joseph "Terry" Nation (8 August 1930 - 9 March 1997) was a Welsh television writer and novelist. Nation first made his name as a comedy writer before becoming a prolific writer for drama, working on many of the most popular British series of the 1960s and 1970s. He made a significant contribution to the long-running BBC science-fiction series Doctor Who from its outset, creating the villainous Daleks which established its early popularity and later devising the recurring character of Davros.
Context: Having returned to writing for Doctor Who, the BBC commissioned Nation to create a new science-fiction drama series. First broadcast in 1975, Survivors is the post-apocalyptic story of the last humans on Earth after the world's population has been devastated by plague. Although the series was well received, Nation's creative vision conflicted with that of producer Terence Dudley, and the final two seasons were produced without Nation's involvement. Meanwhile, screenwriter Brian Clemens claimed that he had related the concept for Survivors to Nation in the late 1960s, having registered it with the Writers' Guild of Great Britain in 1965; Nation denied the allegations. Although the case was ultimately brought before the High Court, both sides withdrew from the proceedings after their legal costs mounted. The production of Nation's next BBC creation, Blake's 7, experienced fewer problems. This series follows a group of criminals and political prisoners who are on the run from the evil "Terran Federation", piloting a stolen spaceship of unknown origin. Running for four seasons from 1978 to 1981, Blake's 7 acquired a worldwide fan following, and proved especially popular in Britain. Although Nation scripted the whole of the first season of Blake's 7, his creative influence subsequently declined in the following two seasons despite writing some key episodes, as script editor Chris Boucher exerted a greater influence on those seasons. Nation didn't write any episodes in the fourth season of Blake's 7. In the 1980s, Nation attempted, without success, to secure funding for a fifth season of Blake's 7. During the 1970s, Nation wrote a children's novel for his daughter Rebecca (after whom he named the character of Rebec in the 1973 Doctor Who serial Planet of the Daleks) titled Rebecca's World: Journey to the Forbidden Planet, as well as a novel based on Survivors.
Question: who were the survivors?
Answer: Survivors is the post-apocalyptic story of the last humans on Earth after the world's population has been devastated by plague.

Problem: Background: Stephen Gregory Yzerman (; born May 9, 1965) is a Canadian retired professional ice hockey player who spent his entire NHL playing career with the Detroit Red Wings and is a member of the Hockey Hall of Fame. He is currently the general manager of the Tampa Bay Lightning. In 2017, Yzerman was named one of the '100 Greatest NHL Players' in history.
Context: Yzerman was born in Cranbrook, British Columbia, but grew up in Nepean, Ontario, (a suburb of Ottawa, now a district in that city) where he attended Bell High School and played for his hometown Nepean Raiders Junior A hockey team. After one season with the Raiders, the Peterborough Petes of the Ontario Hockey League (OHL) drafted him, and he played centre for the Petes from 1981 to 1983. The 1983 NHL Entry Draft was the first for Mike and Marian Ilitch, who had purchased the Detroit Red Wings in the summer of 1982. Jim Devellano, the Red Wings' then-general manager, wanted to draft Pat LaFontaine, who had grown up outside Detroit and played his junior hockey in the area. However, when the New York Islanders selected LaFontaine third overall, Devellano "settled" on Yzerman, drafting him fourth. The Red Wings were prepared to send Yzerman back to Peterborough for one more year, but "after one (training camp) season, you knew he was a tremendous hockey player," said Ken Holland, the current Red Wings general manager who was then a minor league goaltender for the Wings during Yzerman's rookie training camp. Yzerman tallied 39 goals and 87 points in his rookie season and finished second in Calder Memorial Trophy (rookie of the year) voting. That season, Yzerman also became the first 18-year-old to play in an NHL All-Star Game (18 years, 267 days) since the current format was adopted in 1969. This stood as an NHL record for 27 years until Jeff Skinner broke it by eight days.
