Marie still wasn't really sure about goblins and all that they do, however from listening to the other students in the class she could tell they were very possessive creatures. Raising her hand she said "I believe the Ministry taking over Gringotts angered the goblins greatly. For years they had run the bank, to have someone else come in and tell them what to do must have been a great shock to them." Putting her hand down she thought about what she said, she knew it wasn't the most detailed answer but it was one that made sense to her.
