Description of a photo.

This picture shows four teenagers. Two of them are dressing a sparkling costume, and the other two wear tracksuits which point out they represent the USA in some kind of sport competition. Behind them there's a gray-haired man who is probably their coach. The background is covered by huge amounts of people who seem to be cheering them. 

By their reaction we can guess that they won the competition at least they reached their expectations. They will have surely done their best that day to earn that victory. There is such a quantity of spectators that the event in the picture must be quite important.

After getting on the podium and taking the medals, and been interviewed, It is likely that they will have been prepared a celebration by their families, and finally, returning to the gym for train expecting to win the next competitions.
