Why D and not C ?

Is the "certain kind of situation" that they are referring to in D the financial liability that they could face as a result of injuries sustained from nuclear accidents ?

Hi @Maxx, Thanks for the question! (C) isn’t the correct answer because it talks about what happens in a certain situation: a potentially dangerous thing is safe only because the financial security of those responsible for its operation depends on its being safe. But does that situation even apply here? Is it true that nuclear power is safe for only that reason? We can’t be sure, and so we can’t be sure that (C) applies, and that means it’s not going to be the best answer here. (D), on the other hand, adds something we need. If it’s true that the government acts to prevent something, then there’s a real danger that it’ll happen. We can diagram it Act to prevent —> Real danger Which is what we need for this conclusion. Hope this helps! Feel free to ask any other questions that you might have.
