Correct Option (C)
Statements 2 and 3 are correct.
- Statement 2: The passage indicates that the maximum sustainable technical potential of biomass resources (both residues and energy crops) can be realized "without disruption of food and forest resources." This confirms that sustainable biomass production does not inherently necessitate adverse impacts on food supply or forest ecosystems.
- Statement 3: The text mentions that "some climate models rely on biomass-based carbon capture and storage, an unproven technology, to achieve negative emissions." This implies that, with the development of such nascent technologies, biomass could play a role in achieving negative emissions.
Incorrect Options:
Statement 1 is incorrect.
- Statement 1: The passage states that "Climate-energy models project that biomass use could increase nearly four-fold to around 150- 200 exajoules, almost a quarter Of world primary energy in 2050." It also notes that "Projections of the future role of biomass are probably overestimated, given the limits to the sustainable biomass supply." These points contradict the assertion that biomass could meet all the primary energy requirements of the world by 2050.
