Pebble riddle....Lateral Thinking

Many years ago in a small Indian village, a farmer had the misfortune of owing a large sum of money to a village moneylender. The moneylender, who was old and ugly, fancied the farmer's beautiful daughter. So he proposed a bargain.
He said he would forgo the farmer's debt if he could marry his daughter.
Both the farmer and his daughter were horrified by the proposal. So the cunning money-lender suggested that they let providence decide the matter.
He told them that he would put a black pebble and a white pebble into an empty money bag.
Then the girl would have to pick one pebble from the bag.
1) If she picked the black pebble, she would become his wife and her father's debt would be forgiven.
2) If she picked the white pebble she need not marry him and her father's debt would still be forgiven.
3) But if she refused to pick a pebble, her father would be thrown into jail.
They were standing on a pebble strewn path in the farmers field. As they talked, the moneylender bent over to pick up two pebbles. As he picked them up, the sharp-eyed girl noticed that he had picked up two black pebbles and put them into the bag. He then asked the girl to pick a pebble from the bag.
Now, imagine that you were standing in the field. What would you have done if you were the girl? If you had to advise her, what would you have told her?
Careful analysis would produce three possibilities:
1. The girl should refuse to take a pebble.
2. The girl should show that there were two black pebbles in the bag and expose the money-lender as a cheat.
3. The girl should pick a black pebble and sacrifice herself in order to save her father from his debt and imprisonment.
Take a moment to ponder over the story. The above story is used with the hope that it will make us appreciate the difference between lateral and logical thinking. The girl's dilemma cannot be solved with traditional logical thinking. Think of the consequences if she chooses the above logical answers.
What would you recommend to the Girl to do? Think and than proceed further.

i think she should expose him.......

Thats not lateral thinking. Try so more

I think she should throw one of the black pebbles to the ground. As it was the pebble strewn ground, so it would be difficult for anyone to find out as to which coloured pebble was thrown down. The remaining pebble in the bag was black so the villagers would think that the girl has thrown the white pebble down, previously.

I support Rajiv's answers as it is given in many sites.

The answer is absolutely correct Rajiv.....
Good Lateral Thinking :)
