Young East Asian children in sports jerseys in a track and field activity.
There is a group of children in black and white jerseys doing hurdles.
The asian children wearing jerseys could be wearing any color jerseys.  They do not have to be black and white.  Also, just because they are performing in a track and field activity does not mean that the activity has to be hurdles.
