To determine which factor was NOT a factor in the development of cities in Mesopotamia, we can examine each option and eliminate the one that does not fit:

A) Plentiful food supplies made it easier for trade and new jobs.
This is a valid factor in the development of cities in Mesopotamia. The availability of food allowed for increased population, which in turn led to the development of trade networks and the creation of new job opportunities.

B) Silt left behind by floods made the soil fertile and could grow more food.
This is another valid factor in the development of cities in Mesopotamia. The periodic floods in the Tigris and Euphrates rivers deposited silt on the surrounding lands, enriching the soil and making it fertile for agriculture. This abundance of agricultural resources contributed to the growth of cities.

C) Many natural barriers, such as mountains, led to less warfare in the region.
This is also a valid factor in the development of cities in Mesopotamia. The natural barriers, such as mountains, served as protective barriers against invasions and reduced the likelihood of warfare. This stability allowed for the establishment and growth of cities.

D) The development of irrigation systems allowed water into drier areas and helped the population grow.
This is another significant factor in the development of cities in Mesopotamia. The construction of irrigation systems allowed for the cultivation of arid lands and facilitated agricultural production. This, in turn, supported population growth and the establishment of urban centers.

Based on the analysis above, it appears that all the options mentioned (A, B, C, and D) were factors in the development of cities in Mesopotamia. Therefore, none of them can be identified as the incorrect choice.
