Question: Who did Paul Ziert coach who went on to compete in the 1984 Summer Olympic Games?
Context: Hungary first participated at the Olympic Games at the inaugural 1896 Games, and has sent athletes to compete in most Summer Olympic Games and every Winter Olympic Games since then.  The nation was not invited to the 1920 Games after World War I, and it joined the Soviet-led boycott of the 1984 Summer Olympics. 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. Mehdi Aidet (born 3 November 1953) represented Algeria in the 800 m and the 1500 mat the 1980 Summer Olympic Games he qualified for the next round in both events before being eliminated, he then went on to compete in the 1500 mat the 1984 Summer Olympic Games. Hungary competed at the 2004 Summer Olympics in Athens, Greece, from 13 to 29 August 2004.  Hungarian athletes have competed at every Summer Olympic Games in the modern era, except the 1920 Summer Olympics in Antwerp, and the 1984 Summer Olympics in Los Angeles because of the Soviet boycott.  The Hungarian Olympic Committee (Hungarian: "Magyar Olimpiai Bizottság" , "MOB") sent a total of 209 athletes to the Games, 119 men and 90 women, to compete in 20 sports.  Water polo and handball were the only team-based sports in which Hungary had its representation in these Olympic Games.  There was only a single competitor in road cycling and mountain biking. Romania first participated at the Olympic Games in 1900, with a single participant.  The National Olympic Committee for Romania is the Romanian Olympic and Sports Committee, and was created and recognized in 1914.  The nation first sent a team to compete at the Games in 1924, and has only missed two editions each of the Summer Olympic Games and Winter Olympic Games since then.  Notably, Romania was the lone Eastern Bloc nation to participate at the 1984 Summer Olympics, which the other nations boycotted.  That was also Romania's most successful Olympic Games: they won 20 gold medals and 53 medals total. Paul Ziert is a former University of Oklahoma gymnastics coach.  Ziert recruited Bart Conner to the school.  In 1977 and 1978, Ziert's teams won the NCAA Men's Gymnastics championship. Maneyapanda Muthanna Somaya is a former Indian field hockey player from Coorg, Karnataka.  He was a member of Indian squad in many international games, including the team that won the Gold medal at the 1980 Moscow Summer Olympic Games.  Somaya went on to play two more Olympic Games, viz., 1984 Los Angeles Summer Olympic Games, and 1988 Seoul Summer Olympic Games.  He was the captain of the 1988 Olympics team. 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. Poland first participated at the Olympic Games in 1924, and has sent athletes to compete in every Summer Olympic Games since then, except for the 1984 Games, when they participated in the Soviet-led boycott of the 1984 Summer Olympics.  Poland has also participated in every Winter Olympic Games. Bart Conner (born March 28, 1958) is a retired American Olympic gymnast.
