Final answer:
The answer that does not describe a reason for Sargon's conquest of Sumer is the claim that Akkadians were able to hide in the mountains, which is inconsistent with Mesopotamia's geography.
Step-by-step explanation:

The factors that did contribute included the division of the Sumerian city-states and the conflicts over natural resources among kingdoms. However, the statement that the Akkads were able to hide in the mountains is not a reason for Sargon's conquest of Sumer, as Mesopotamia is predominantly a flat region with no significant mountains for hiding.
