Answer
The answer is silver. At the 1984 Summer Olympics in Los Angeles, Joyner-Kersee won her first Olympic medal, a silver, in the heptathlon. She finished second to Glynis Nunn of Australia, who set a new world record. Joyner-Kersee's performance marked the beginning of her successful Olympic career, as she went on to win three gold medals and a bronze medal in subsequent Olympic Games.
