The correct answer is: "agriculture"

A traditional economy, like the ones that existed both in Egypt and Kush, were economic systems based on customs and beliefs to determine the amount and type of goods and services produced and their subsequent allocation.

These economic systems were typically rural and farm-based subsistence economies, where food produced by agricultural activities was mostly directed to self-consumption, and there was almost no trade,  and barter was the predominant form of exchange.
