question: Why did Bob and Sally stop looking for the treasure?
story: On a nice and sunny day, Bob and Sally walked to the beach. When they got there, the first\newlinething they wanted to do was to look for buried treasure. To find the treasure they had\newlinebrought two shovels and two buckets. They both started digging holes in the sand with\newlinetheir shovels. After looking very hard for treasure for an hour, they didn't find\newlineanything. This made Bob and Sally very sad. They gave up and went to play in the\newlinewater. While they were playing in the water, Sally found a bottle with a little paper\newlineinside. Sally opened the bottle and found a treasure map. Sally showed the map to Bob and\newlinethey started to look for the treasure.  After walking every step that the map said, they\newlinestarted digging with their shovels. After digging a really a big hole, they found a\newlinebox. They were very happy that they found it and wanted to see what was inside. Bob slowly\newlineopened the box and there was a very big pearl.  Next, they ran to a special store to ask\newlineabout the pearl. The worker in the store told Bob and Sally that the pearl could make them\newlinerich. Bob and Sally looked at each other and decided not to sell it. They took the pearl\newlinehome and saved it in a special box, so they could remember their day at the beach.
