1. First time: The text doesn't explicitly state what the wise men said the first time. It only mentions the question about how the king solved his problem.
2. Second time: The text doesn't specify what animals the wise men took to the palace the second time.
3. Wise men's actions: Based on the story provided with question 45, the wise men likely observed the situation with the mice and elephants, and perhaps advised the king on how to deal with the mice problem.
