Document 3: List of Olympic medalists in basketball: Basketball is a sport contested at the Summer Olympic Games. A men's basketball tournament was first held at the 1904 Olympics as a demonstration; it has been held at every Summer Olympics since 1936. In the 1972 Olympics, the final game between the United States and the Soviet Union was a controversial one, as the game was ended and replayed twice by a FIBA (International Basketball Federation) official without the authority to do so, before the Soviet Union won their first gold medal, which would have been won by the United States if the game was not started against the rules. The U.S. filed a formal protest but was rejected by FIBA. As a result, the United States refused to accept the silver medal, and no player has ever claimed his medal. After a protest of the Soviet war in Afghanistan, the United States boycotted the 1980 Moscow Olympics. The Soviet Union responded by leading the 1984 Summer Olympics boycott, citing security concerns in the United States. Both boycotts affected basketball at the Olympics, as both had successful basketball teams at the time. In 1989, the International Olympic Committee (IOC) decided to allow professional athletes to compete in the Olympics, and starting in 1992, the National Basketball Association (NBA) allowed its players to participate. Women's basketball was first held at the 1976 Summer Olympics. Both events have been held at every Olympic Games since.
Document 4: Major achievements in swimming by nation: This is a list of the best results achieved by athletes from different nations at four major competitions where swimming events are (or were) competed. Results are based on major competitions according to FINA's historical records: the swimming and open water swimming events at the Olympic Games, the swimming and open water swimming events at the FINA World Aquatics Championships, the FINA Short Course Swimming World Championships and the defunct FINA World Open Water Swimming Championships. The results listed here only refer to swimming and open water swimming events. Medals earned by athletes from defunct NOCs or historical teams have been merged with the results achieved by their immediate successor states, as follows: Russia inherits medals from the Soviet Union and the Unified Team; Serbia inherits medals from Yugoslavia; Australia inherits medals from Australasia; and Germany inherits medals from West Germany and East Germany. The table is pre-sorted by total number of gold medal results, silver medal results and bronze medal results, respectively. When equal ranks are given, countries are listed in alphabetical order.
Document 5: Jeff Float: Jeffrey James Float is a former American competitive swimmer, World Record holder, World Champion and Olympic Gold Medalist. He qualified for the 1980 U.S. Olympic Swimming Team in three individual events, but could not participate when the United States boycotted the Moscow 1980 Summer Olympic Games. Four years later, he competed at the 1984 Summer Olympics in Los Angeles. As the peer-elected Team Captain, Jeff earned a Gold Medal in the men's 4×200-meter freestyle relay, and finished fourth in the individual 200-meter freestyle event. That Gold Medal 4x200-meter freestyle is now considered the third greatest relay of all time.
Document 6: Fred Borchelt: Earl Frederick "Fred" Borchelt (born June 12, 1954 in Staten Island, New York) is an American former competitive rower and Olympic silver medalist.

In 2007, Borchelt was awarded the Congressional Gold Medal, the highest award given to civilians by the U.S. legislative branch. The entire American team that was supposed to compete at the 1980 Summer Olympics were awarded the medals because of the 1980 Summer Olympics boycott.
Document 7: Terence Anderson (sport shooter): Terence "Terry" M. Anderson (born c. 1946) is a retired Australian-born American sports shooter who specialized in the 25 meter rapid fire pistol event. He won the national championships in Australia in 1969 and 1971, in New Zealand in 1971–1973 and in the United States in 1975, 1977, 1979, 1993, 1997, 1999, 2000.

He was selected to the 1980 Olympic team, but missed the games due to their boycott by the United States and selected to the 1996 Olympic Team in Atlanta.
Document 8: Quietly Confident Quartet: The Quietly Confident Quartet was the self-given name of the Australian men's 4 × 100 metres medley relay swimming team that won the gold medal at the 1980 Summer Olympics in Moscow. The United States boycotted the Moscow Olympics in protest against the Soviet invasion of Afghanistan and, through the 2016 Olympics, the Australian victory remains the only occasion the United States has not won the event at Olympic level since its inception in 1960. The quartet consisted of backstroker Mark Kerry, breaststroker Peter Evans, butterflyer Mark Tonelli and freestyler Neil Brooks. The team was nominally led by its oldest member Tonelli, who was 23 and was also a spokesperson for the Australian athletes' campaign for their right to compete at the Olympics against the wishes of the Fraser Government. The team was seen as an unlikely prospect to win; all four of the swimmers had clashed with swimming authorities over disciplinary issues and three experienced suspension or expulsion from the Australian team during their careers.
Document 9: Marshall Brooks: Marshall Brooks was a nineteenth-century sportsman who was the British Amateur High Jump champion in 1874 and 1876, world record holder for the High Jump on three occasions, as well as a rugby union international who represented England in 1874.
Document 10: Mark Tonelli: Mark Lyndon Tonelli (born 13 April 1957), whose birth name was Mark Lyndon Leembruggen, is an Australian former backstroke, butterfly, and freestyle swimmer of the 1970s and 1980s, who won a gold in the 4×100-metre medley relay at the 1980 Moscow Olympics as a makeshift butterfly swimmer in the self-named "Quietly Confident Quartet". Tonelli unofficially led the relay team and was an athletes' spokesperson who fought for the right of Australian Olympians to compete in the face of a government call for a boycott to protest against the Soviet invasion of Afghanistan.
Document 11: Umpiring in the 1974–75 Ashes series: The main point of contention in the umpiring of the 1974–75 Ashes series was the intimidatory bowling of the Australian fast bowlers Dennis Lillee and Jeff Thomson. There were a few other issues, though there were the usual cases of batsmen being given out or not out despite the differing opinions of the players and umpire. At the time, umpires had no recourse to slow motion replays and had to make decisions based on what they saw in a split second, with the benefit of the doubt always going to the batsman. As a result it was not uncommon for umpires to make mistakes, which over the course of a long series tended to cancel each other out. The best an umpire could do was to make an honest judgement based on what he saw. Tom Brooks and Robin Bailhache were the umpires in all six Tests, but were junior for so important a series. Brooks having made his debut in the 1970–71 Ashes series and Bailhache in the First Test at Brisbane. Unusually for Australian umpires of the time Brooks had played First Class Cricket – he had been a lively fast-medium bowler – and as a result was more able to connect with the Test players, and was more forgiving of short-pitched deliveries which he saw as a natural part of the game. This helped England in 1970–71 when they had the fast bowlers John Snow and Bob Willis, but proved fatal for their batsmen in 1974–75.
Document 12: Neil Brooks: Neil Brooks (born 27 July 1962) is an Australian former sprint freestyle swimmer best known for winning the 4 × 100 m medley relay at the 1980 Olympics in Moscow as part of the "Quietly Confident Quartet". Brooks was as much known for his swimming achievements as he was for disciplinary incidents. He often found himself in conflict with officialdom and threatened with sanctions. His international career ended when he was suspended for drinking 46 cans of beer on the return flight to Australia after the 1986 Commonwealth Games. In retirement, he became a news presenter and sports commentator, but was fired amid alcohol problems.
Document 13: Great Britain at the 1964 Summer Olympics: The United Kingdom competed as Great Britain at the 1964 Summer Olympics in Tokyo, Japan. 204 competitors, 160 men and 44 women, took part in 124 events in 17 sports. British athletes have competed and won at least one gold medal in every Summer Olympic Games. Future Liberal Democrat leader Menzies Campbell represented Britain at the 200m.
Document 14: Australia at the 1976 Summer Paralympics: Australia has participated in every Summer Paralympic Games since the inception of the Paralympics in the year 1960. The 1976 Paralympic Games in Toronto was Australia’s fifth Paralympic Games. Australia competed in 10 out of the 13 sports and were able to win medals in six of these sports. There were 44 athletes representing Australia at the Games with a number of these athletes participating in multiple sports. Of the 44 athletes, 34 were males and 10 were females. As a team, Australia won 42 medals, 16 of which were gold. This placed it just outside the top 10 in 11th position at the end of the Games. The Australian team won more gold medals at the 1976 Paralympic Games than at any of the previous four Paralympic Games. 27 athletes finished on the podium in their respective events. This represents more than half the number of athletes that Australia sent to Toronto. Six world records were broken by Australian athletes on their way to winning their respective events.
Document 15: 1984 United States men's Olympic basketball team: The 1984 United States men's Olympic basketball team competed in the 1984 Summer Olympics in Los Angeles, representing the United States. The team, coached by Indiana Hoosiers coach Bob Knight, won the gold medal. It was the last amateur U.S. team to win an Olympic gold medal in men's basketball. The team was considered one of the strongest in U. S. history as it featured four of the five 1984 consensus first team All-Americans in Michael Jordan, Patrick Ewing, Wayman Tisdale, and Sam Perkins. The talent pool for the U.S. team was so strong that Charles Barkley and John Stockton — future first round picks and hall of famers — did not make the roster.
