sentences: 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.
The 4 × 100 metres relay or sprint relay is an athletics track event run in lanes over one lap of the track with four runners completing 100 metres each.
 The first runners must begin in the same stagger as for the individual 400 m race.
 A relay baton is carried by each runner and must be passed within a 20 m changeover box (usually marked by yellow lines) which extends 10 m on either side of each 100 m mark of the race.
 Another line is marked 10 m farther back, marking the earliest point at which the outgoing runner may begin (giving up to 10 m of acceleration before entering the passing zone).
Bohemia, an autonomous part of Austria-Hungary until 1918, competed at some of the early modern Olympic Games.
 The team made its debut at the 1900 Summer Olympics.
 After World War I, Bohemia became part of the new Czechoslovakia, and Bohemian athletes competed for Czechoslovakia at the Olympics.
 After the 1992 Summer Olympics and the dissolution of Czechoslovakia into the Czech Republic and Slovakia in 1993, Bohemian athletes competed for the Czech Republic at the Olympics.
 If these post-war appearances are counted, Bohemia has missed only three Olympics: the inaugural 1896 Summer Olympics, the 1904 Summer Olympics (the first held outside Europe) and the boycotted 1984 Summer Olympics.
For the 1984 Summer Olympics, a total of thirty-one sports venues were used.
 Two venues from the 1932 Summer Olympics, the Los Angeles Memorial Coliseum and the Rose Bowl, were used for these Games.
 Between the 1932 and the 1984 Summer Olympics, the expansion of professional sports teams assisted in the growth of the facilities that would be used for the 1984 events.
 In an effort to control costs in the wake of the problems incurred during the 1976 Summer Olympics in Montreal, only two new permanent venues were constructed, both using corporate sponsorship though neither were mentioned in the official Olympic report.
 Many of the other venues had temporary adjustments and returned to their normal usage once the 1984 Olympics were completed.
 Stanford Stadium in Palo Alto and the Rose Bowl later served as venues for the Super Bowl, the FIFA World Cup, and the FIFA Women's World Cup.
 The velodrome that was constructed for the 1984 Games was demolished in 2003.
Bhutan, a country in Southern Asia, participated in nine Summer Olympic Games between its debut in the 1984 Summer Olympics in Los Angeles, United States and the 2016 Summer Olympics in Rio de Janeiro, Brazil.
 The highest number of Bhutanese athletes participating in a Summer Games is six in both the 1984 Summer Olympics and the 1992 Summer Olympics in Barcelona, Spain.
 Bhutan competed at the Rio Summer Games from 5 to 21 August 2016.
 No Bhutanese athlete has ever won a medal at the Olympics.
 The two athletes who were selected to represent Bhutan at the Rio Games were Karma in the women's individual archery tournament and Kunzang Lenchu in the women's 10 metre air rifle shooting contest.
 Along with the two athletes, the Secretary General of Bhutan's Olympic Committee, and two coaches, the country's delegation was led by the heir presumptive to the Bhutan throne Jigyel Ugyen Wangchuck.
 Karma was selected as the flag bearer for the opening ceremony while Lenchu held it at the closing ceremony.

 Rafer Johnson lit the cauldron at the opening ceremony.
 The Los Angeles Olympic Organizing Committee (LAOOC) tasked Burson-Marsteller, the public relations agency of AT&T, with the organization of the relay.
 The controversial Youth Legacy Kilometer, which turned the relay into a sponsored, fund-raising event, pioneered the idea of runners being nominated by the public.

 For 32 years, only men were allowed to compete.
