Question

gold, iron, the nile, little rainfall, copper, more rainfall; northern kush, both, southern kush

• Northern Kush was drier with access to the Nile and gold, while Southern Kush had more rainfall and access to iron and copper. Both regions had access to valuable mineral resources.

• Northern Kush: gold, the Nile, little rainfall
• Both: (no exclusive shared items beyond mineral resource access, but if categorizing by overlap of resource type logic, none fit directly; the distinct items are split as above)
• Southern Kush: iron, copper, more rainfall
