Ancient greece did not have fertile soil, which limited crop production. because of this, greeks relied on imported goods from other city-states and countries. they would use their own crops to trade for other highly needed goods. the greek government did not regulate all goods being traded, except for grain. wheat trading was controlled and purchased by a special grain buyer called a sitone. grain fed large, highly-populated city-states and was valuable during droughts. based on this passage, what positive effect did the government regulation of grain have on greece?
