Problem: Background: Wasim Akram (Urdu: wsym khrm; born 3 June 1966) is a former Pakistani first-class cricketer, cricket commentator and television personality. He is acknowledged as one of the greatest bowlers of all time. A left-arm fast bowler who could bowl with significant pace, he represented the Pakistan cricket team in Test cricket and One Day International (ODI) matches. In October 2013, Wasim Akram was the only Pakistani cricketer to be named in an all-time Test World XI to mark the 150th anniversary of Wisden Cricketers' Almanack.
Context: Akram was a significant figure in the 1992 Cricket World Cup held in Australia and New Zealand when Pakistan won the tournament. In the final, against England, his innings of 33 runs off 19 balls pushed Pakistan to a score of 249 runs for 6 wickets. Akram then took the wicket of Ian Botham early on during the English batting innings; and, when brought back into the bowling attack later on, with the ball reverse swinging, he produced a spell of bowling which led to Allan Lamb and Chris Lewis being bowled in successive deliveries in one over. His performances earned him the Man of the Match award for the final. In 1993, Akram took two consecutive 4-wicket hauls against Sri Lanka in Sharjah, in which 7 out of 8 wickets were either LBW or bowled.  In the 1992-1993 Total International Series in South Africa (involving Pakistan, West Indies and South Africa), he took 5 wickets against South Africa and got his 200th wicket in his 143rd match. Akram took 46 wickets in calendar year 1993, his best year ever in ODIs. His average was less than 19, with an economy rate of less than 3.8 runs per over. He took six 4-wicket hauls in 1993, the most by him in any year. In the 1996 Cricket World Cup, Akram missed the quarterfinal match against India which Pakistan lost and went out of the World Cup. Wasim's great career was often tainted by controversy, not least in the Caribbean in April 1993, his maiden tour as Pakistan's captain. During the team's stop-over in Grenada, he was arrested along with three teammates--Waqar Younis, Aaqib Javed and Mushtaq Ahmed--and two female British tourists; he was charged with possession of marijuana. Between 1994 and 1996, he took 84 wickets in 39 matches.  From January 1992 to December 1997, Akram played 131 matches and took 198 wickets at an average of 21.86, with 14 4-wicket hauls in ODIs.
Question: what sport did he play?
Answer: he produced a spell of bowling which led to Allan Lamb and Chris Lewis being bowled in successive deliveries in one over.

Problem: Background: Vaslav Nijinsky (also Vatslav; Russian: Vatslav Fomich Nizhinskii; Russian: ['vatsl@f f@'mjitc njI'zinskjIj]; Polish: Waclaw Nizynski; 12 March 1889/1890 - 8 April 1950) was a ballet dancer and choreographer cited as the greatest male dancer of the early 20th century.
Context: Nijinsky spent his summer after graduation rehearsing and then performing at Krasnoe Selo in a makeshift theatre with an audience mainly of army officers. These performances frequently included members of the Imperial family and other nobility, whose support and interest were essential to a career. Each dancer who performed before the Tsar received a gold watch inscribed with the Imperial Eagle. Buoyed by Nijinsky's salary, his new earnings from giving dance classes, and his sister Bronia's employment with the ballet company, the family moved to a larger flat on Torgovaya Ulitsa. The new season at the Mariinsky theatre began in September 1907, with Nijinsky employed as coryphee on a salary of 780 roubles per year.  He appeared with Sedova, Lydia Kyasht and Karsavina. Kchessinska partnered him in La Fille Mal Gardee, where he succeeded in an atypical role for him involving humour and flirtation. Designer Alexandre Benois proposed a ballet based upon Le Pavillon d'Armide, choreographed by Fokine to music by Nikolai Tcherepnin. Nijinsky had a minor role, but it allowed him to show off his technical abilities with leaps and pirouettes. The partnership of Fokine, Benois and Nijinsky was repeated throughout his career. Shortly after, he upstaged his own performance, appearing in the Bluebird pas de deux from the Sleeping Beauty, partnering Lydia Kyasht. The Mariinsky audience was deeply familiar with the piece, but exploded with enthusiasm for his performance and his appearing to fly, an effect he continued to have on audiences with the piece during his career.  In subsequent years, Nijinsky was given several soloist roles. In 1910, Mathilde Kschessinska selected Nijinsky to dance in a revival of Petipa's Le Talisman. Nijinsky created a sensation in the role of the Wind God Vayou.
Question: What was his most successful performance?
Answer:
Each dancer who performed before the Tsar received a gold watch inscribed with the Imperial Eagle.
