The escalating crisis of global climate change necessitates radical shifts in energy production, making nuclear power a subject of intense debate. Proponents frequently champion it as a crucial low-carbon alternative, arguing that its near-zero operational emissions offer a reliable pathway to decarbonization necessary for meeting international climate targets. They point to the immense baseload capacity of nuclear plants, which operate consistently regardless of weather fluctuations, unlike intermittent renewables. However, this optimism is tempered by significant concerns regarding radioactive waste disposal—a problem requiring secure containment for millennia—and the high upfront capital costs associated with building new facilities. Furthermore, geopolitical risks concerning proliferation and potential accident scenarios cast a long shadow over its perceived safety. Therefore, while nuclear energy presents undeniable technological advantages in emissions reduction, its viability as a sole solution remains contingent upon resolving complex issues of waste management and ensuring equitable global access to advanced technology.

According to the passage, what is the central argument regarding nuclear energy's role in combating climate change?

According to the passage, what is the central argument regarding nuclear energy's role in combating climate change?

Accepted Answer

While possessing significant low-carbon potential, nuclear energy's effectiveness hinges on successfully navigating deep challenges related to waste disposal and accessibility.. C is correct because the passage synthesizes the claims (low-carbon potential) with the complications (waste/accessibility) to form a nuanced conclusion. A is incorrect because the passage presents counterarguments that prevent it from claiming nuclear energy is unequivocally the best solution. B is incorrect because while cost is mentioned, the passage frames waste and accessibility as equally critical limiting factors. D is incorrect because the passage does not advocate for abandoning all non-fossil fuels but rather weighs nuclear against other options.
