    Once a king was walking around a pool with his ministers (大臣). Suddenly, he came
up with (想出) an idea. He asked, "How many baskets of   1   are there in the pool?" The
ministers couldn't give an answer. The king was angry, "You   2   answer my questions in
three days!"
    Three days passed, but   3   of the ministers had the answer. Just then, a child said
that he knew it. The king told the ministers   4   the child to the pool. To his surprise,
the child   5   and said with a smile, "It is   6 . No need to go to the pool." This made
the king pleased. "All right. Let us know   7 ." The child said, "If you know the   8
of the basket, the answer is known.   9   it is as big as the pool, there is one basket of
water; half as big, two baskets…" " Stop! That's it. You have got the answer. They were
thinking of things   10  a wrong way."
