Respuesta :
The fact that the magician repeats the word "lazy" so much should give the story a humorous tone. He even names Man's children in a humorous way "the Malazy". We can even assume he was wordplaying with Malaysia, the country. This supports the idea that the Eldest Magician had a really good sense of humour.
In the light of this, the correct answer is "Repetition of the word lazy makes the tone humorous".
