Australian media are reporting today that doubts have been raised about the ages of Chinese medal - winning athletes as long ago as the Sydney Olympic Games in 2000 . Age - falsification has become a burning issue since the Beijing Games last month , where it was alleged that Chinese gymnast He Kexin , who won two gold medals , was underage and therefore should have been ineligible to compete in the event . Rules introduced in 1997 to prevent the exploitation of under - aged gymnasts stipulate that competitors are required to be at least 16-years - old in the year the Olympics are held .

Question: Why is it an issue if the Chinese gymnast is not sixteen years old ?
Answer: None of the above choices .The gymnast can not understand the rules properly .If the gymnast is not sixteen years old then he in violation of Olympic rules .The gymnast can not be tested for drugs at that age .
