Social Science (087) — AI-generated practice question

Stage 1 — Extracting iron ore (Primary Sector):
This is a primary sector activity because it involves directly extracting a natural resource (iron ore) from the earth. Mining and quarrying fall under the primary sector.

Stage 2 — Melting ore in a furnace to produce steel rods (Secondary Sector):
This is a secondary/industrial sector activity because a natural product (iron ore) is transformed into a manufactured good (steel rods) through an industrial/manufacturing process.

Stage 3 — Transporting and selling steel rods to construction firms (Tertiary Sector):
This is a tertiary/service sector activity because transport and trade do not produce goods themselves but aid and support the movement and sale of goods produced in other sectors.

• The three-sector classification is based on nature of activity — this is the key phrase examiners look for.
• Link each stage clearly: natural resource extraction → primary; manufacturing/transformation → secondary; transport/trade/services → tertiary.
• One line of classification + one line of justification per stage is the ideal structure for a 3-mark answer.
• Avoid writing long definitions; focus on applying the concept to the given scenario.
