Problem: Background: Bure was born in Moscow in 1971 to Vladimir and Tatiana Bure. At age 12, his parents separated, and he remained with his mother. Vladimir Bure, a Russian swimming legend, had dreams of Pavel becoming a professional swimmer, but he aspired to play hockey at an early age. He attended his first tryout with the CSKA Moscow hockey school at the age of six, despite his limited skating ability.
Context: At age 16, Bure began his professional hockey career playing for CSKA Moscow. He was invited to the senior club's training camp for the 1987-88 season. Although he was deemed too young, and not yet ready, for the Soviet League, Bure earned minimal playing time filling in for absent regulars. He made his debut in September 1987, and played five games for the senior team, scoring his only goal in his first game.  Bure joined the club full-time in 1988-89 and amassed 17 goals, a Soviet League record for rookies. The record would last for 18 years until Alexei Cherepanov scored 18 goals in 2006-07. Bure added 9 assists for 26 points to earn the league's rookie of the year honours. His individual success helped CSKA Moscow capture their thirteenth consecutive Soviet championship and twelfth consecutive IIHF European Cup in 1989 (they repeated as European champions the following year).  As a member CSKA, Bure joined a lineup that featured several future NHL players, including linemates Sergei Fedorov and Alexander Mogilny, as well as Igor Larionov, Viacheslav Fetisov, Sergei Makarov, and Vladimir Konstantinov. The combination of Bure, Fedorov and Mogilny formed a promising combination for head coach Viktor Tikhonov, with expectations to replace the previous top Soviet line, the K-L-M combination of Vladimir Krutov, Larionov and Makarov. The trio was short-lived, as Mogilny defected to play for the Buffalo Sabres in 1989, and Fedorov joined the Detroit Red Wings the following year.  In his third and final season with the Red Army, Bure tied for the lead in team-scoring with Valeri Kamensky, tallying 46 points. His 35 goals was second in the league, one goal behind Ramil Yuldashev of Sokil Kyiv. Bure turned down a three-year contract extension in August 1991, which resulted in him being left off the roster of the Soviet team for the Canada Cup.
Question: What did he do with CSKA?
Answer: professional hockey

Problem: Background: Stallman was born to Alice Lippman, a school teacher, and Daniel Stallman, a printing press broker, in 1953 in New York City. Stallman had a difficult relationship with his parents, as his father had a drinking habit and verbally abused his stepmother. He later came to describe his parents as "tyrants". He was interested in computers at a young age; when Stallman was a pre-teen at a summer camp, he read manuals for the IBM 7094.
Context: As a first-year student at Harvard University in fall 1970, Stallman was known for his strong performance in Math 55. He was happy: "For the first time in my life, I felt I had found a home at Harvard."  In 1971, near the end of his first year at Harvard, he became a programmer at the MIT Artificial Intelligence Laboratory, and became a regular in the hacker community, where he was usually known by his initials, RMS (which was the name of his computer accounts). Stallman received a bachelor's degree in physics (magna cum laude) from Harvard in 1974.  Stallman considered staying on at Harvard, but instead he decided to enroll as a graduate student at MIT. He pursued a doctorate in physics for one year, but left that program to focus on his programming at the MIT AI Laboratory.  While working (starting in 1975) as a research assistant at MIT under Gerry Sussman, Stallman published a paper (with Sussman) in 1977 on an AI truth maintenance system, called dependency-directed backtracking. This paper was an early work on the problem of intelligent backtracking in constraint satisfaction problems. As of 2009, the technique Stallman and Sussman introduced is still the most general and powerful form of intelligent backtracking. The technique of constraint recording, wherein partial results of a search are recorded for later reuse, was also introduced in this paper.  As a hacker in MIT's AI laboratory, Stallman worked on software projects such as TECO, Emacs for ITS, and the Lisp machine operating system (the CONS of 1974-1976 and the CADR of 1977-1979--this latter unit was commercialized by Symbolics and LMI starting around 1980). He would become an ardent critic of restricted computer access in the lab, which at that time was funded primarily by the Defense Advanced Research Projects Agency. When MIT's Laboratory for Computer Science (LCS) installed a password control system in 1977, Stallman found a way to decrypt the passwords and sent users messages containing their decoded password, with a suggestion to change it to the empty string (that is, no password) instead, to re-enable anonymous access to the systems. Around 20% of the users followed his advice at the time, although passwords ultimately prevailed. Stallman boasted of the success of his campaign for many years afterward.
Question: what did he study there?
Answer: programming

Problem: Background: Krishnan Nair (25 July 1939 - 16 November 1980), better known by his stage name Jayan, was an Indian film actor, naval officer, stunt performer and cultural icon of the 1970s. He starred in over 120 Malayalam films. During his film career, he was primarily an action star and was particularly famous for his macho image and unique style. He was reputed for his chauvinistic appeal and well known for performing stunts of a dangerous nature on his own.
Context: In the late 1990s and early 21st century, there was a resurgence of Jayan's screen persona in Kerala and his old movie scenes came to prominence again. It was owed mostly to programs by popular mimicry stage artists in the State, whose imitations of the star's mannerisms caught on and soon became commonplace in college stage events, television programs and mimicry stage shows along with quotes of superhuman strength known as Jayan quotes. However, it has been pointed out that many grotesquely imitated screen dialogues of Jayan are not actually his, but that of dubbing artist Aleppey Ashraf, who dubbed for many of his characters after his death.  The "comeback" of Jayan and his renewed popularity lately may be taken as an affirmation that Jayan has not been replaced even nearly three decades after his death. Today, Jayan is best remembered as the first and best action star of Malayalam cinema, so far, besides his trademark colourful attire, risky stunts, machismo mannerisms and unique speaking style. He has rightly won immortality in the hearts of the Malayalam film fans as a martyr in his yearning to thrill and entertain them even by putting his life at stake. Madhu, a famous actor prominent in the 1960s, once stated in an interview: "Jayan will forever be young and alive. No one can ever visualise him as an old man."  A film titled Avatharam presently under production, is attempting to bring back his screen persona using advanced technologies. A documentary on Jayan's life and death Jayan - The Man behind the Legend is nearing completion for release in the near future.
