Background: Hugo Sanchez Marquez (born 11 July 1958) is a retired Mexican professional footballer and manager, who played as a forward. A prolific goalscorer known for his spectacular strikes and volleys, Sanchez is widely regarded as Mexico's greatest-ever footballer, and one of the greatest players of his generation. In 1999, the International Federation of Football History and Statistics voted Sanchez the 26th best footballer of the 20th century, and the best footballer from the CONCACAF region. In 2004 Sanchez was named in the FIFA 100 list of the world's greatest living players.
Context: Sanchez made 58 appearances for Mexico between 1977 and 1994, scoring 29 goals. Prior to representing the senior side, as a teenager he represented Mexico at the 1975 Pan American Games on home soil, where he won a gold medal, and at the 1976 Summer Olympics. He participated in three FIFA World Cup tournaments, making 8 World Cup appearances in total, and scoring once. He helped Mexico win the 1977 CONCACAF Championship to seal qualification for the 1978 FIFA World Cup in Argentina; at the age of 19, he took part in the final tournament, where Mexico lost all three of their group games and suffered a first round elimination. After Mexico failed to qualify for the 1982 FIFA World Cup in Spain, Sanchez was a part of the Mexico team that reached the quarter-finals of the 1986 World Cup on home soil, losing out to eventual runners-up West Germany in a penalty shootout. He scored his only World Cup goal during his nation's opening match of the tournament on 3 June, the winning goal in a 2-1 victory over Belgium, although he also missed a penalty in Mexico's second group match against Paraguay, and was later booked, causing him to miss the final group match. Four years later, however, Mexico once again missed out on the final tournament as they were suspended from the 1990 FIFA World Cup in Italy. Despite his advancing age, he later played a key role in helping Mexico to the final of the 1993 Copa America, at the age of 35; he scored once in a 2-0 victory over Ecuador in the semi-finals, although Mexico eventually finished as runners-up to Argentina. Sanchez later also appeared at the 1994 FIFA World Cup in the United States, his final major tournament, where Mexico suffered a round of 16 elimination; he made his only appearance in the tournament on 19 June, in Mexico's opening match of the competition, a 1-0 defeat to Norway.
Question: In what event did he when a gold medal in 1975?
Answer:

Background: Zheng He (Chinese: Zheng He ; 1371-1433 or 1435) was a Chinese mariner, explorer, diplomat, fleet admiral, and court eunuch during China's early Ming dynasty. He was originally born as Ma He in a Muslim family, later adopted the conferred surname Zheng from Emperor Yongle. Zheng commanded expeditionary voyages to Southeast Asia, South Asia, Western Asia, and East Africa from 1405 to 1433. His larger ships stretched 120 meters or more in length.
Context: Zheng He was born Ma He to a Muslim family of Kunyang, Kunming, Yunnan, China. He had an older brother and four sisters. Ma He's religious beliefs became all-embracing and eclectic in his adulthood. According to Dreyer (2007), the Liujiagang and Changle inscriptions suggest that Zheng He's devotion to Tianfei (Princess of Heaven, the patron goddess of sailors and seafarers) was the dominant faith to which he adhered, reflecting the goddess' central role to the treasure fleet. John Guy mentions, "When Zheng He, the Muslim eunuch leader of the great expeditions to the 'Western Ocean' (Indian Ocean) in the early fifteenth century, embarked on his voyages, it was from the Divine Woman that he sought protection, as well as at the tombs of the Muslim saints on Lingshan Hill, above the city of Quanzhou." Zheng He was a great-great-great-grandson of Sayyid Ajjal Shams al-Din Omar, who served in the administration of the Mongol Empire and was the governor of Yunnan during the early Yuan dynasty. His great-grandfather was named Bayan and may have been stationed at a Mongol garrison in Yunnan. Zheng He's grandfather carried the title hajji, while his father had the sinicized surname Ma and also the title hajji, which suggests that they had made the pilgrimage to Mecca. It also suggests that Zheng He may have had Mongol and Arab ancestry and that he could speak Arabic. In the autumn of 1381, a Ming army invaded and conquered Yunnan, which was then ruled by the Mongol prince Basalawarmi, Prince of Liang. In 1381, Ma Haji (Zheng He's father) died in the fighting between the Ming armies and Mongol forces. Dreyer (2007) states that Zheng He's father died at age 39 while resisting the Ming conquest. Levathes (1996) states Zheng He's father died at age 37, but it is unclear if he was helping the Mongol army or just caught in the onslaught of battle. Wenming, the oldest son, buried their father outside of Kunming. In his capacity as Admiral, Zheng He had an epitaph engraved in honor of his father, composed by the Minister of Rites Li Zhigang on the Duanwu Festival of the 3rd year in the Yongle era (1 June 1405).
