Subsidiary Conclusion?

@jgoldman, Great question. When you say that it makes sense if you say, "Most of the government's budget should be redirected to preventing spills because it makes little sense that the entire annual budget for prevention is less than the amount spent annually on one typical cleanup site," you're absolutely right. The clause after "because" is the subsidiary conclusion because it's supporting the clause before "because." Remember, the subsidiary conclusion is just another term for the intermediate conclusion or major premise. This means that it's a conclusion of another premise that is used to support another conclusion. The proposal about how the government's budget should be redirected is the claim that the whole stimulus is designed to support, so it's the main conclusion, and this is why (C) is the correct answer. Does that make sense? Let us know if you have any other questions!

Why isn't the answer D? I was stuck between C and D, but just want to make sure I understand why the answer couldn't be D. Thank you!!!
