The following text is for questions 56 to 60.

    King Ranubaru had a very pretty princess. She loved playing with water very much. One day, people of kingdom suffered from a strange disease. A lot of people died. Physicians failed to cure the people.

    One day, an old man visited the King. He said that kingdom could be free from the disease with the help of rare flower which grew in the middle of a lake. The lake was just at Mount Semeru’s foot. However, the flower could only be taken by the princess. Sadly, the king let the princess do the heavy task.

    After the long journey, the princess and her people arrived at the lake. The water of the lake soon attracted the princess to play with it. She jumped into the lake and forgot about the task. She refused to go back to the kingdom.

    Hearing about the princess’ behavior, the king got angry. He went to see the princess and said, “People are waiting for you to bring the flower to cure them, but you forgot about the task. If you refuse to go back to the palace, you’d better stay here in the lake forever!”

    Surprisingly, the princess turns into a white flower. The king, sadly, took the flower out of the lake and brought it to the palace. Amazingly, people of the kingdom could be cured by seeing the flower. The flower is known as the water lily or ‘Bunga Teratai’ in the Indonesian language.
