Dora, who was eight years old, went to the grocery store with her mother. Dora pushed the grocery cart while her mother put items into it. Dora's mother remained near Dora at all times. Peterson, another customer in the store, noticed Dora pushing the cart in a manner that caused Peterson no concern. A short time later, the cart Dora was pushing struck Peterson in the knee, inflicting serious injury. If Peterson brings an action, based on negligence, against Dora's mother, will Peterson prevail? 
Yes, if Dora was negligent.  Yes, because Dora's mother is responsible for any harm caused by Dora.  Yes, because Dora's mother assumed the risk of her child's actions.  Yes, if Dora's mother did not adequately supervise Dora's actions.
