Answer :[color:"#3A495A"]There is only one monk with a dot (one is greater than zero), it is the monk who can see the other ones.
He did not really know that he had a dot but he knew that the other monks had no dot.
Logically he found out that he was the one who had to jump.
The first day and the second day, he was too afraid to jump and the first day he finally decided to do it to save the world.
The other monks would had not jump anyway, they were just expecting that someone else would had jumped.[/color]
