The king had four people that helped the king a lot. Three of them were the Royal Wizard, the Royal Mathematician and the Court Jester.
The Royal Wizard and the Royal Mathematician always thought about the truth so they could not get the real moon. I think they were serious when they solved problems.
However, the Court Jester was very innovative aand he thought outside the box. He asked the Prince Lenore at first, and he followed her idea to make a "moon". The Counrt Jester was different from those two men.
When the second problem appeared, the Royal Wizard and the Royal Mathematician only thought how to hide the moon but they did not care the Prince Lenore's health. They made the king fly into a rage. They could solve the problem comprehensively.
The Court Jester asked the Prince how could the moon be in the sky again, and solve the prblem effectively by asking a question. Maybe the Court Jester did not know as many things as the Royal Wizard and the Royal Mathematician, but he was creative and tose two men could not do this like theCourt Jester.
