V. Short Answer Questions
VI. Detailed Answer Questions
Common Mistakes
1. ❌ Confusing agro-based and mineral-based industries: Cotton textiles use agricultural raw materials (agro-based), while iron and steel use mineral ores (mineral-based). ✅ Agro = agriculture; Mineral = ores. 2. ❌ Mixing up "Manchester of India" and "Cottonpolis of India": Ahmedabad = "Manchester of India"; Mumbai = "Cottonpolis of India." ✅ Both are cotton textile centres but have different nicknames. 3. ❌ Confusing public and private sector industries: SAIL, BHEL, NTPC are government-owned (public); Tata, Reliance, Infosys are private. ✅ Ownership determines classification. 4. ❌ Thinking cottage industries need heavy capital: Cottage industries are home-based with minimal investment and simple tools — the opposite of large-scale industries. ✅ Cottage = small, home-based, minimal capital. 5. ❌ Listing only one factor for industrial location: Exam questions require multiple factors — always mention at least 4-5 (raw materials, power, water, transport, labour, market, government policies). ✅ Always list multiple factors. 6. ❌ Forgetting forest-based and marine-based industries: Students often remember agro-based and mineral-based but skip forest-based (paper, lac) and marine-based (fish processing) in classification answers. ✅ All four types must be mentioned. 7. ❌ Confusing TISCO and first modern steel: TISCO was established in 1907 at Jamshedpur, but the first modern steel production was at Kulti in 1874. ✅ Kulti = first (1874); TISCO = major (1907).
