Question: Both Sam Greco and Mike Bernardo were players of which sport?
Context: The Spectre M4 is an Italian submachine gun that was produced by the SITES factory in Turin.  It was designed by Roberto Teppa and Claudio Gritti in the mid-1980s.  Production in Italy ceased in the year 1997, with the closure of SITES, but proceeded in very small numbers in Switzerland through Greco Sport S.A., a company founded by Gritti, until 2001.  The Spectre is a compact and light weapon, designed for instant firepower in close combat at short ranges.  The four models have top-folding buttstocks, and were available with or without a forward handgrip ahead of the magazine housing.  The largely polymer Spectre has a stamped-steel receiver. Women's sport in Australia started in the colonial era.  Sport made its way into the school curriculum for girls by the 1890s.  World War II had little impact on women's sport in the country.  After the war, women's sport diversified as a result of new immigrants to the country.  In the 1990s, the percentage of media coverage for women's sport on radio, television and in newspapers was not at parity with male sport.  Basketball is nominally professional in Australia but players do not earn enough from the sport to compete full-time.  Some Australians have gone overseas to play professional sport.  Women make up a large number of television spectators for Australian sport.  In person, netball has large percentage of female spectators.  The Australian Federal and State governments have encouraged women to participate in all areas of sport. Roller hockey is a team sport played on a wood, asphalt, cement or sport tile surface, in which players use a hockey stick to shoot a hard plastic hockey puck into their opponent's goal to score points.  It is considered a contact sport but body checking is prohibited.  However, there are exceptions to that with the NRHL which involves fighting.  Inline hockey teams are composed of up to four lines of players including two forwards and two defensemen on each line.  There are five players including the goalie from each team on the rink at a time.  It is the goalie's job to prevent the other team's players from scoring.  Teams normally consist of 16 players that sit on the bench until it is their turn to play.  As the name suggests it is played on inline skates. Sam "Slam 'em" Greco (born 3 May 1967) is a retired Australian former full contact karateka, super heavyweight K-1 kickboxer and mixed martial artist of Italian descent.  He was the 1994 Karate World Cup champion and holds notable kickboxing victories over Branko Cikatic, Ernesto Hoost, Mike Bernardo, Stefan Leko, and Ray Sefo, as well as MMA victories over Heath Herring and Shungo Oyama. Netball is a sport that has one of the largest female participation rates within the commonwealth, most popular in the United Kingdom, Australia and New Zealand, with more than 20 million athletes participating in the sport.  Netball is a ball sport played by two teams of seven players in which goals are scored by shooting the ball through a netted ring.  Netball relies heavily on muscular endurance and bursts of rapid acceleration to “break free” from an opponent as well as, sudden and rapid change of directions in combination with jumping to receive a pass, intercept a ball or rebound.  The sudden stop-start motion of the game is what often leads to serious injuries in participants.  Higher grade players, in both senior and junior competitions, are more susceptible to injuries than lower grade players, due to the high intensity and rapid pace of the game.  An injury is most commonly defined as one that has occurred while participating in sport and which led to one of the following consequences: a reduction in the amount or level of sports activity; need for medical advice or treatment; and/or adverse economic or social effects for the athlete. Jianzi (), tī jianzi (踢毽子), tī jian (踢毽) or jianqiú (毽球), also known by other names, is a traditional Chinese national sport in which players aim to keep a heavily weighted shuttlecock in the air by using their bodies, apart from the hands, unlike in similar games peteca and indiaca.  The primary source of jianzi sport is a Chinese ancient game called "cuju" of the Han dynasty 2000 years ago.  Jianzi's competitive sport types are played on a badminton court using inner or outside lines in different types of jianzi's competitive sports, respectively.  it can be played also artistically, among a circle of players in a street or park, with the objective to keep the shuttle 'up' and show off skills.  In Vietnam, it is known as "đá cầu" and is the national sport.  In the Philippines, it is known as "sipa" and was also the national sport until it was replaced by arnis in December 2009. A fantasy sport (also known less commonly as rotisserie or roto) is a type of online game where participants assemble imaginary or virtual teams of real players of a professional sport.  These teams compete based on the statistical performance of those players' players in actual games.  This performance is converted into points that are compiled and totaled according to a roster selected by each fantasy team's manager.  These point systems can be simple enough to be manually calculated by a "league commissioner" who coordinates and manages the overall league, or points can be compiled and calculated using computers tracking actual results of the professional sport.  In fantasy sports, team owners draft, trade and cut (drop) players, analogously to real sports. Michael "Mike" Bernardo (28 July 1969 – 14 February 2012) was a South African kickboxer and boxer from Cape Town.  Bernardo was known as Beru-chan in Japan, where he has taken part in K-1 World GPs since 1994.  He holds notable wins over Mirko Cro Cop, Andy Hug, Francisco Filho, Branko Cikatic, Stan Longinidis and 3 straight wins over K-1 legend Peter Aerts. The NFL Golf Classic was a golf tournament on the Champions Tour from 1993 to 2002.  It was played in May or June at the Upper Montclair Country Club in Clifton, New Jersey.  It was a joint production with the NFL and attracted top NFL talent to play in a tournament within a tournament (separate from the golf pros).  NFL players Trent Dilfer and Al Del Greco frequently played to the top of the leaderboard.  The 2000 edition was also the final competitive win for golfing great Lee Trevino.  In its day it was amongst the more popular stops of the Champions Tour. 9-man (also nine-man, nineman, 9man) is a team sport with some characteristics of volleyball utilizing nine players per side and a slightly larger court (10 by 20 meters).  Historically, the sport was played by Chinese immigrants to the US, who predominantly hailed from Toisan (Taishan) city in Guangdong province of China.  In the late 1930s the sport was used as a means to socially connect the laborers in Chinatowns across the United States.  Teams from Boston and Providence, RI held the first organized nine-man tournament in 1938 which later spread to Chinatowns in other large US and Canadian cities.  The North American version of 9-Man continues to grow today with a popular rotating tournament called the NACIVT uniting thousands of players and spectators each September over Labor Day weekend.  It is unclear whether the sport was also played in the Asian Games in 1958 and in 1962 held in Tokyo and Jakarta, respectively, or if they were simply playing volleyball with nine players.  The sport has not made a reappearance in the Asian Games since, and many believe that the rules of nine-man are exclusive to the community that plays in North America.  The sport is the subject of an award-winning documentary called 9-Man that was completed in 2014 and had its world premiere at IFFBoston on April 27, 2014 at 1pm.  The film was broadcast on the PBS World Channel series America ReFramed on May 5, 2015.
