01 Why was a regular supply of raw materials necessary for craft centres engaged in trade?
Answer and explanation
Correct answer: D. To maintain continuous production
Explanation: The governing concept is the relationship between raw-material supply, craft production, and trade. Beads, ornaments, tools, or other manufactured goods could be produced for exchange only when artisans regularly received the required stone, metal, shell, clay, or other inputs. Therefore option D is correct: a dependable supply kept production continuous and helped meet demand. The other options do not explain the economic need for raw materials.
