Answer:
If the answer requires you to choose locations on the map then it would be those 2 circles that are located in the green area.
Step-by-step explanation:
The cities are not listed on the map provided. However, based on the location of the Fertile Crescent on the map, some cities involved in Agricultural trade can be inferred.
Babylon is a famous city in history due to the power that the Babylonian empire wielded at some point. The city was located towards the south of the Fertile Crescent and as such was able to engage in Agricultural activities and trade with cities in Anatolia and Mesopotamia.
Assur as well was located in the Fertile Crescent. Assur was the capital of the Assyrian empire before Nineveh and was a rich city. This was probably in part because of the trade that developed in the city in Agriculture. Agriculture was such a big part of the economy that sometimes Barley was used as currency.
