Answer:
I have no life but I can die. What am I?
When it comes to me, you go on red and stop on green. What am I?
I go around in circles, but always straight ahead, never complain, no matter where I am led.
What has words but never speaks?
What is made of wood, but can't be sawed?
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
