📘 Enrichment Notes (Concept Precision)

🔹 Understanding the Three Sectors (UPSC Lens)

🟢 Primary Sector

• Directly exploits natural resources
• Examples:
  • Agriculture
  • Dairy farming
  • Fishing
  • Mining (extraction)

✔ Pair 2: Dairy farm — Correctly matched

🟠 Secondary Sector

• Converts raw materials into finished or semi-finished goods
• Manufacturing & processing
• Examples:
  • Spinning
  • Weaving
  • Factories

✔ Pair 4: Weaving cloth — Correctly matched

🔵 Tertiary Sector

• Service-based activities
• Supports Primary & Secondary sectors
• Examples:
  • Transport
  • Storage
  • Banking
  • Trade
  • Consultancy
  • Technical services

❌ Pair 1: Storage of agricultural produce — Incorrectly matched
📌 Storage is a service, hence tertiary, not secondary.

✔ Pair 3: Mineral exploration — Correctly matched
📌 Important UPSC nuance:

• Mining → Primary
• Mineral exploration → knowledge-intensive, survey, consultancy → Tertiary

🧩 Final Tally

➡️ Correct pairs = 3

🧘‍♂️ IAS Monk Whisper

What extracts is primary, what transforms is secondary, what supports is tertiary.
