The treatment quiz:

Mary and her husband live on the south bank of a river. Her husband wants her to stay at home and not cross the river to the town. She wants to go to town. There is a bridge across the river, but men have been robbing and killing people who cross the bridge, and Mary’s husband won’t give her money for the ferry. Mary begins saving the grocery money for the ferry and crossing the river to town on the ferry while her husband is away. Finally, she meets a man in town and takes him as a lover. She crosses the river more frequently and he gives her money to get back home.  He gets mad at her one day and refuses to give her the return fare home. She asks the ferryman to let her charge the return trip but he refuses, saying it is against company policy. Finally, she crosses the bridge and is killed.
