इस परिच्छेद के सन्दर्भ में, निम्नलिखित पूर्वधारणाएँ बनाई गई हैं :
- 1.कुछ जलवायु-ऊर्जा प्रतिरूप यह सुझाते हैं कि शक्ति-जनन के ईंधन के रूप में बायोमास का उपयोग ग्रीनहाउस गैस उत्सर्जनों को कम करने में सहायक होता है
- 2.शक्ति-जनन के ईंधन के रूप में बायोमास का उपयोग करना, खाद्य एवं वन संसाधनों को बाधित किए बिना संभव नहीं है
इन पूर्वधारणाओं में कौनसी वैध है/हैं ?
Read this question in English
With reference to the passage, following assumptions have been made:
1. Some climate-energy models suggest that the use of biomass as a fuel for power generation helps in mitigating greenhouse gas emissions
2. It is not possible to use biomass as a fuel for power generation without disrupting food and forest resources
Which of these assumptions is/are valid?
(a) 1 only · (b) 2 only · (c) Both 1 and 2 · (d) Neither 1 nor 2
उत्तर और व्याख्या · explanation in English
Answer: (a) केवल 1
Biomass has 'the highest mitigation potential of all renewable sources', and climate-energy models project its use rising nearly four-fold — so these models treat it as cutting emissions. The passage also gives a potential available without disrupting food and forest resources, which rules out statement 2.
- ✓ 1. 'Highest mitigation potential', a projected four-fold rise in use, and some models even rely on biomass for 'negative emissions'.
- ✗ 2. The passage puts 80 – 170 exajoules a year within reach 'without disruption of food and forest resources'.
Remember · An assumption the passage directly contradicts is invalid, however plausible it sounds.
