Detailed explanation-1: -Early writing was used primarily as a means of recording and storing economic information. This tablet most likely documents deliveries and distributions of grain such as barley and emmer wheat, although the absence of verbs in early texts makes them difficult to interpret with certainty.

The farmers in Sumer created levees to hold back the floods from their fields and cut canals to channel river water to the fields. The use of levees and canals is called irrigation, another Sumerian invention.
