A leading environmental research institute published a report asserting that mandatory carbon capture technologies for all heavy industries are the most economically viable and effective solution to combat climate change. The report cited projections showing that the long-term economic benefits of avoiding severe climate impacts far outweigh the upfront costs of implementing carbon capture, and that existing renewable energy technologies alone cannot meet global energy demands quickly enough to prevent catastrophic warming.
Correct: B
The report asserts that carbon capture is the 'most economically viable and effective solution' for climate change, based on (1) long-term benefits outweighing costs and (2) renewables alone not being sufficient. The question implies we need to identify what would be most useful in evaluating this claim, which means assessing its viability or effectiveness.
Option (B) is the most critical for evaluating the claim that carbon capture is the 'most economically viable and effective solution'. The argument assumes the *implementability* and *scalability* of carbon capture on a global scale. If the international cooperation and massive infrastructure investments required are of 'unprecedented levels' and 'questionable feasibility', then even if the technology works and benefits outweigh costs in theory, it ceases to be the 'most economically viable and effective *solution*' in practice. This directly challenges the practicality and effectiveness of the proposed solution's global deployment.
(A) This challenges the premise that renewables *alone cannot meet global demands quickly enough*. While valid, the argument also rests on carbon capture being *economically viable and effective*. (B) directly addresses the viability of carbon capture itself.
(C) This points to a limitation of carbon capture, but the report speaks about 'heavy industries' where it is applicable. The report doesn't claim it's a silver bullet for *all* emissions, only that it's the most viable for combating climate change overall, given the limitations of renewables. (B) questions its viability even within its scope.
(D) This challenges the *accuracy* of the cost-benefit analysis, which is important. However, even if the quantification is speculative, the core challenge of whether it's truly a *solution* given its implementation hurdles (B) is more fundamental to its 'effectiveness' as a *solution*.
(E) This raises concerns about competitive disadvantage for *individual industries*, which is an important policy consideration, but doesn't undermine the claim about carbon capture being the 'most economically viable and effective solution' for climate change *globally*.
