Answer:
What can you keep after giving it to someone?
I know a word of letters three, add two and less there will be.
A father's child, a mother's child, yet no one's son
What is between heaven and earth?
What is red and smells like blue paint?
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.
