Fishing Trip<br>Tommy went fishing in the lake. He got a new boat the day before. Unfortunately he did not know how to use the boat. He tried everything, but couldn't get it started. Instead he decided to fish from the bridge.
The bridge was over the lake.
We can assume the bridge is over the lake because Tommy is fishing in a lake from a bridge. The model doesn't understand this common sense notion.
