Answer:
D. the Euphrates River Valley
Step-by-step explanation:
The Fertile Crescent is the name for the region spreading from the Middle East to the part of Egypt and North Africa. The name comes from the fact that the region is shaped like the crescent, and that it was the cradle of farming in the times of ancient civilizations. It was in these parts that the civilizations of Sumer in Mesopotamia and Egypt blossomed and started domesticating crops and plants.
The region includes –
- valley of the Nile in Egypt
- the modern-day Palestine and Israel
- modern-day Lebanon
- modern-day Syria
- modern-day Iraq
- the southeast region of Turkey
Therefore, it includes the valley of the river Euphrates as well, as it flows through Iraq and Syria, and it is the place where civilizations of Mesopotamia were developed.
