If you don't understand, ask, is this the first time in the history of the world track and field championships that nine people participated in the 100-meter final?

Yes, because according to the rules of the competition, eight people will enter the final, and the preliminaries will be divided into two groups. The top three players in each group enter the finals, and then the best players in the remaining two groups enter the finals. This may lead to a tie for the eighth person. Previously, the track was not allowed (only eight lanes), and it was decided by lottery. Now the technology is developed, and the result can be accurate to three digits after the second. It is very unlikely that he wants to tie it, but at this time Sue was caught red-handed, and it was the other party who tied him together. -I read the following answer to modify the answer. A few people think that the scores of all three people are 9 "99, but they are not. 9 "99 is the published score, only two digits behind the second place. Now the score can be accurate to three digits after the second, and the third digit is held by the referee. One of the three people wins (if the first two are tied, there will be no nine), and Sue and the other one will be nine ".
