Answer:
I am a piece of paper that takes most people 3 or 4 years to get. What am I?
With a halo of water and a tongue of wood; stone as skin long I stood.
The sun bakes me, the hand breaks me, the foot treads on me, and the mouth tastes me. What am I?
Angels and pilots work with me.
The more holes you cover the lower I go.
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.
