The following text is for questions 1 to 3.

    A long time ago, there lived a powerful Chinese king. He was successful in bringing greatness to his kingdom. He made a lot of military conquests. Then, his success made him worry about his life. He realized that one day he would get older and finally die. He wanted eternal life. He gave orders to all of his people to help him live forever. Those who disobeyed the order would be punished severely. This made everybody in the kingdom afraid of him.

    The king had a military adviser, namely Xu Fu. Xu Fu was very concerned about the situation. He wanted to find a way to save the people. One day, Xu Fu came to the palace. He told the king that there was a special grass that could make the king live eternally. The grass could be found on an island far to the east. Xu Fu offered himself to find the grass on condition that the king supplied 3,000 girls and 3,000 boys to go with him and enough food for 3 years. The emperor granted the request immediately and let Xu Fu go east. The king gave him two big ships.

    Two months later, Xu Fu and the 6,000 children departed to the east. The king prepared a big party on the day of their departure day. Soon, the king stopped punishing innocent citizens. He was already dreaming about living eternally. Day after day, he was waiting for Xu Fu's return.

    After five years of hoping for Xu Fu's return, one day the king fell sick and died. Xu Fu and the 6,000 children never returned to China. They landed on a big island and stayed there. When the children were grown up, they married each other and became a big nation. The nation was known as Japan.

What was Xu Fu requested to the emperor?
