Which of the following can lead to food security problem?
1. Using agricultural and forest residues as feedstock for power generation
2. Using biomass for carbon capture and storage
3. Promoting the cultivation of energy crops
Select the correct answer using the code given below:
(a) 1 and 2 only · (b) 3 only · (c) 2 and 3 only · (d) 1, 2 and 3
उत्तर और व्याख्या · explanation in English
Answer: (b) केवल 3
Only energy crops are said to compete with food production and to affect food prices. Residues are by-products of farms and forests, and carbon capture and storage is mentioned only as an unproven technology — neither is linked to food.
- ✗ 1. For residues the passage worries about supply logistics and collection costs, not food.
- ✗ 2. Carbon capture and storage is called 'an unproven technology'; no link to food is drawn.
- ✓ 3. Energy crops 'compete with food production and may have undesirable impacts on food prices'.
Remember · Tie each statement to the exact sentence about it; a risk named for one source (energy crops) does not carry over to others.
