New smart watch<br>It was Christmas time. Suzy really wanted a new watch. She begged for one for Christmas. But her parents said no initially. To her delight she saw one under the tree after all.
Suzy and her parents went to buy the smart watch together. 
The statement is definitely incorrect because it says that Suzy really wanted a watch, but her parents originally said no.  Then "to her delight" she saw a watch under the tree after all.  This meant that it was a surprise in which case she couldn't have gone with to buy the watch.  Perhaps the system was confused because the agent didn't indicate exactly who bought the watch.
