The correct answer to this open question is the following.
The geographic feature of Mesopotamia that led to the Sumerians being easily taken over was the Tigris and Euphrates Rivers that made it easy for their enemies to navigate and invade them.
Sumeria was the oldest civilization known to man. Sumerians settled in the middle of the Tigris and Euphrates Rivers in the Middle East region. There, they developed agriculture techniques and learn how to use the flood of the rivers to grow crops in that fertile soil. That is how they prosper for some time until their enemies could access their city-states navigating through both rivers.
<span>During Jefferson’s presidency the cities were, largely in
the purpose of -coast, commerce, and center- trade. Trade was utmost system
during these eras. The main cities that were involved were Boston, New York, Newport, Philadelphia, and
Charles Town. These five largest cities were commercially centered
for this exchange and trade for goods and products, internationally across the seas
and Atlantic ocean. However, they also served as defense during crisis times
and for any imminent invasion. If today’s life feels more in the cities, these
capitals were also the core hubs for social, political, religious and urbanity
for one’s life. </span>
