Answer:
Agrarian Culture: Domestication, grains, seeds
Complex civilization: creation of laws, bureaucracy, Metal armor
Agrarian Culture: The first Agrarian culture started in Mesopotamia: the land between the Tigris and Euphrates rivers, which is now modern day Iraq. The valleys, had trees (small ones not super huge ones), no huge stones, and no metals, but with the soil large crops of wheat and barley, grasses that had been domesticated earlier in the mountains nearby could be planted. They also grew lentils and chickpeas and herded sheep and goats.
Complex civilization: If you look at the Agrarian culture and what they were able to obtain (and a little research), you will be able to look from their perspective and see that the last three things would be of a more complex civilization, or a more advanced one.
