Background: Dion Francis DiMucci (born July 18, 1939), better known mononymously as Dion, is an American singer, songwriter whose work has incorporated elements of doo-wop, rock and R&B styles--and, most recently, straight blues. He was one of the most popular American rock and roll performers of the pre-British Invasion era. He had 39 Top 40 hits in the late 1950s and early 1960s as a solo performer, with the Belmonts or with the Del Satins. He is best remembered for the singles "Runaround Sue", "The Wanderer", "Ruby Baby" and "Lovers Who Wander", among his other hits.
Context: Bob and Gene Schwartz also signed Dion's friends, the Belmonts, (Carlo Mastrangelo, Fred Milano, and Angelo D'Aleo), a vocal group named for nearby Belmont Avenue, and teamed them, with Dion singing lead. The new group's breakthrough came in early 1958, when "I Wonder Why" (on their newly formed "Laurie" label) made No. 22 on the U.S. charts. Dion said of the Belmonts; "I'd give 'em sounds. I'd give 'em parts and stuff. That's what 'I Wonder Why' was about. We kind of invented this percussive rhythmic sound. If you listen to that song, everybody was doing something different. There's four guys, one guy was doing bass, I was singing lead, one guy's going 'ooh wah ooh,' and another guy's doing tenor. It was totally amazing. When I listen to it today, oftentimes I think, 'man, those kids are talented.'"  Their initial hit was followed by "No One Knows" and "Don't Pity Me," which also charted the Billboard Top 100. This success won a place for Dion and the Belmonts on the ill-fated "The Winter Dance Party" tour with Buddy Holly, Ritchie Valens, the Big Bopper (J.P. Richardson), Frankie Sardo, and other performers. On February 3, 1959, after a concert stop in Clear Lake, Iowa, Holly and others decided to charter a flight to the next venue rather than travel on the tour bus. Dion was invited to accompany the group but decided that he did not want to spend $36 for the flight, as it was the same monthly rent his parents paid for his childhood apartment and he couldn't justify the indulgence. The plane crashed, killing all on board; Holly, Valens, Richardson, and the pilot Roger Peterson. Dion and the Belmonts continued on the tour, along with Frankie Sardo, while Bobby Vee, then an unknown artist, performed in Holly's place at the very next concert. Later, Jimmy Clanton, Frankie Avalon, and Fabian were added to replace the other now-deceased headliners.  Dion and the Belmonts' next single, "A Teenager in Love," was released in March 1959, eventually hitting No. 5 on the U.S. pop charts and No. 28 in the UK. The group's biggest hit, "Where or When," was released in November of that year, and reached No. 3 on the U.S. charts. However, in early 1960, Dion checked into hospital for heroin addiction, a problem he had had since his mid-teens. Further single releases for the group that year were less successful. There were musical, personal and financial differences between Dion and members of the Belmonts, and in October 1960, Dion decided to quit for a solo career. By the time of their breakup, all eight Laurie releases had charted on the Hot 100.
Question: Did the group continued producing music after Dion'S departure ?
Answer: By the time of their breakup, all eight Laurie releases had charted on the Hot 100.

Background: Garry Kimovich Kasparov (Russian: Garri Kimovich Kasparov, Russian pronunciation: ['garjI 'kjim@vjItc ka'spar@f]; born Garik Kimovich Weinstein, 13 April 1963) is a Russian, and formerly Soviet, chess grandmaster, former world chess champion, writer, and political activist, who many consider to be the greatest chess player of all time. From 1986 until his retirement in 2005, Kasparov was ranked world No. 1 for 225 out of 228 months. His peak rating of 2851, achieved in 1999, was the highest recorded until being surpassed by Magnus Carlsen in 2013. Kasparov also holds records for consecutive professional tournament victories (15) and Chess Oscars (11).
Context: As a teenager, Kasparov tied for first place in the USSR Chess Championship in 1981-82. His first win in a superclass-level international tournament was scored at Bugojno, Bosnia and Herzegovina in 1982. He earned a place in the 1982 Moscow Interzonal tournament, which he won, to qualify for the Candidates Tournament. At age 19, he was the youngest Candidate since Bobby Fischer, who was 15 when he qualified in 1958. At this stage, he was already the No. 2-rated player in the world, trailing only World Chess Champion Anatoly Karpov on the January 1983 list.  Kasparov's first (quarter-final) Candidates match was against Alexander Beliavsky, whom he defeated 6-3 (four wins, one loss). Politics threatened Kasparov's semi-final against Viktor Korchnoi, which was scheduled to be played in Pasadena, California. Korchnoi had defected from the Soviet Union in 1976, and was at that time the strongest active non-Soviet player. Various political maneuvers prevented Kasparov from playing Korchnoi, and Kasparov forfeited the match. This was resolved by Korchnoi allowing the match to be replayed in London, along with the previously scheduled match between Vasily Smyslov and Zoltan Ribli. The Kasparov-Korchnoi match was put together on short notice by Raymond Keene. Kasparov lost the first game but won the match 7-4 (four wins, one loss).  In January 1984, Kasparov became the No. 1 ranked player in the world, with a FIDE rating of 2710. He became the youngest ever world No. 1, a record that lasted 12 years until being broken by Vladimir Kramnik in January 1996; the record is currently held by Magnus Carlsen.  Later in 1984, he won the Candidates' final 8 1/2 -4 1/2  (four wins, no losses) against the resurgent former world champion Vasily Smyslov, at Vilnius, thus qualifying to play Anatoly Karpov for the World Championship. That year he joined the Communist Party of the Soviet Union (CPSU), as a member of which he was elected to the Central Committee of Komsomol in 1987.
