1 and 3

The correct answer is Option 3: 1 and 3.

Statement 1: The pre-capitalist conquerors benefited from their domination by exacting a continuous flow of tribute. — Correct. Pre-capitalist conquerors extracted wealth from the regions they controlled by collecting tribute from the economic surplus produced there.

Statement 2: They interfered with the economic base. — Incorrect. Pre-capitalist conquerors generally did not interfere with the existing economic base. They mainly extracted tribute while allowing traditional systems of production to continue.

Statement 3: They simply took the tribute that was skimmed off the economic surplus that was produced traditionally in the subjugated areas. — Correct. Their method of extraction involved taking the surplus produced by existing economic systems rather than restructuring production.
