Why do the colors on the stop light changed colors?

They change colors to show you what to do on the street. Green means go and that everything is O.K. , Yellow means slow down and warns you that you will have to stop soon, red means stop and that it is not safe to keep going, flashing yellow lights are ment to tell you to slow down and be careful, and red flashing lights are meant to be used as a stop sign were you have to wait for others to pass to be able to get through it's also a warning sign for high traffic.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
