Museum curator: Our ancient Egyptian collection includes an earthenware hippopotamus that resembles a child' s toy. It was discovered in a tomb, upside down, with its legs broken off. We know that the ancient Egyptians believed the dead had to wage eternal war with beasts. Breaking the legs off a representation of an animal was thought to help a deceased person in this war. We conclude that, far from being a toy, this hippopotamus was a religious object. Which one of the following is an assumption required by the curator's argument?
A: Earthenware figures were never used as children's toys in ancient Egypt.
B: The hippopotamus' legs were not broken through some natural occurrence after it was placed in the tomb.
C: The tomb in which the hippopotamus was found was not reentered from the time of burial until archaeologists opened it.
D: The hippopotamus was originally placed upside down in the tomb.
Choose A, B, C or D as your solution.
