Answer:
You are on an electric train. Which direction will the smoke fly in?
Defends your noggin from the hard pavement
A precious gift, yet it has no end, no beginning, and nothing in the middle.
With sharp edged wit and pointed poise. It can settle disputes without making a noise.
What demands an answer, but asks no question?
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.
