Three kids practice martial arts, one has a yellow belt, on a red belt and the other a white belt.
Three Boys in Martial Art Outfits are walking down the Street.
Just because they are kids, that does not mean they are boys.  Just because they practice martial arts and have belt rankings, that does not mean they are currently in their outfits.  Just because there are boys together, that does not mean that they are walking down the street.
