There is a Gold Box, a Silver Box and a Bronze Box.
Ada splits $1,001 into the boxes in any way she likes.
Bella, without knowing how Ada splits the money, chooses one box.
The money in the box chosen by Bella will be quadrupled, tripled or doubled
if it is the Gold, Silver or Bronze box respectively and
Bella gets the money inside the chosen box.
Ada will get the money (original amount) in the other two boxes.
