Please answer the following question: I'm taking a test and have to guess the right answer to the question after the article. Article: Lion was the King of the Jungle . One day, Giraffe told Lion, "Rabbit says he is the new King of the Jungle." "What?" Lion was very angry. He went to meet Rabbit. The other animals followed him to see what he would do. "Rabbit," said Lion, "Why do you say that you are the new King of the Jungle?" "Oh, but it's true," said Rabbit. "I'm faster and cleverer than you. We can have a competition ." "All right," said Lion. Rabbit took Lion to a deep ravine . He said, "If I fly down to the ravine faster than you, I am faster and cleverer than you. So I go, or you will go first?" "Of course I will go first," said Lion, "I am the King of the Jungle!" He then threw himself into the deep ravine. Rabbit smiled and said to the other animals. "I am your new king now.
