Question Type:
Principle Support
Stimulus Breakdown:
Conclusion: Our country should not sign the agreement.
Evidence: Signing the agreement would probably reduce economic growth in our country and others (although the agreement probably would significantly reduce ocean pollution)
Answer Anticipation:
Prephrasing a correct answer for Principle Support usually just takes the form of saying "IF premise, THEN conclusion", or otherwise something like "we should base our decision on what the author was talking about in the premise".
Here my prediction would be "IF something would probably reduce our economic growth and that of others, THEN we shouldn't do it." Any answer choice that doesn't help me to prove we "SHOULD NOT" do something is useless.
We could also potentially see a correct answer say "avoiding a reduction in economic growth is more important than reducing pollution in the oceans" as a way of showing which of our competing concerns SHOULD take precedence.
Correct Answer:
B
Answer Choice Analysis:
(A) This says "IF unlikely to achieve stated goal, shouldn't sign". The right side matches our conclusion, but the left side doesn't match our premise. This agreement IS likely to achieve its stated goal of reducing ocean pollution.
(B) Possibly! And ultimately, yes. Given that this agreement would do one good thing and one bad thing, deciding whether to sign is largely a function of "do we care more about the good thing or the bad thing"? This answer tells us that we care more about the bad thing, and that pushes us towards the idea that we shouldn't sign.
(C) This says "IF a better meansof [reducing ocean pollution] is likely possible, shouldn't sign". The right side matches the conclusion, but the left side doesn't match the premise. We have no idea whether a better means of reducing ocean pollution is likely possible.
(D) This relates to the topic at hand, but it doesn't give us a definitive push in the direction of sign vs. don't sign. It only takes us as far as "we should consider the economic effects". Okay, we considered them. Now what?
(E) This is our one quick elimination, because it gives a rule that says "IF _____ , then should sign". We only have use for rules that say "IF ____ , then shouldn't sign."
Takeaway/Pattern: This type of correct answer isn't as compelling as the ones we usually get in Principle Support, the type that are conditional rules that say "IF premise, THEN conclusion". The other type of correct answer, which (B) represents, is more of a Rule of Thumb that tells us how we should make a decision.
