Which one of the following statements best reflects the crux of the passage?
(a) Generation of energy from municipal solid waste is inexpensive. · (b) Biomethanation is the most ideal way of generating energy from municipal solid waste. · (c) Segregation of municipal solid waste is the first step in ensuring the success of waste-to-energy plants. · (d) The biodegradable component of India's municipal solid waste is not adequate to provide energy from waste efficiently/effectively.
उत्तर और व्याख्या · explanation in English
Answer: (c) नगरीय ठोस अपशिष्ट का पृथक्करण, अपशिष्ट-से-ऊर्जा संयंत्रों की सफलता को सुनिश्चित करने में पहला कदम है ।
Waste-to-energy fits in the chain after segregation, and the right technology depends on what the waste contains, yet segregation at source is rare in India. So segregation is the first requirement for waste-to-energy plants to work.
- ✗ (a) The cost of waste-to-energy is not discussed; the budget point is that collection and transport take most of the money.
- ✗ (b) Biomethanation is 'a major solution' for the biodegradable part, not the most ideal way for all municipal waste.
- ✓ (c) Waste-to-energy 'fits in the chain after segregation', and technology depends on the waste's make-up, which cannot be handled well while segregation at source is 'rare'.
- ✗ (d) The biodegradable share is 'a little over 50 per cent' and biomethanation can process it — the opposite of 'not adequate'.
Remember · The crux links the passage's problem (rare segregation) to its solution chain; reject superlatives like 'most ideal' that the passage never uses.
