    Few serious ecological problems are the result of

    Why this is right

    If we perform our translation, "Few A's are B = Most A's are ~B" this is saying that Most serious eco problems are not the result of govt mismanagement which is what we were looking for. Conversationally, once we're told that few serious ecological problems are the result of government mismanagement, we know from the stimulus that the solution to most serious ecological problems will require major changes in consumer habits. Making consumers change their habits in major ways requires that our solutions are economically enticing. So, solving most serious ecological problems will require that we make our solutions economically enticing.

    Skill tested: Sufficient Assumption · how this choice captures the argument's function is the move to repeat next time.

  2. Out of Scope4% picked this

    No environmental problems that stem from government mismanagement have solutions that

    Out of Scope: do result from govt. Unrelated to Goal Since this answer choice doesn't talk about "few/most serious ecological problems" (the New Idea from our conclusion), it is functionally hopeless, so we don't really need to read it. If we do read it, this answer is doing the super common Fake Opposite trap you see on Assumption questions. If we say "tall people love their mom", the answer will illicitly accuse the author of assuming "small people don't love their mom". We were told that "problems that don't result from government mismanagement will require solutions that are economically feasible", so this answer is just flipping that to say "problems that do result of government mismanagement will not have solutions that are economically feasible".

  3. Unrelated to Goal15% picked this

    Major changes in consumer habits can be made

    Since this answer choice doesn't talk about "few/most serious ecological problems" (the New Idea from our conclusion), it is functionally hopeless, so we don't really need to read it. If we do read it, this answer is trying to appeal to us by feeling like a valid Necessary Assumption. Since it feels like the author is implicitly suggesting that we'll need to make major changes in consumer habits economically enticing, this answer is calling out an Assumption that such a thing is even feasible.

  4. Reversed Most Statement21% picked this

    Most environmental problems that are not the result of government mismanagement are

    We needed to know that most major ecological problems are not the result of government mismanagement. This is telling us that most problems that are not the result government mismanagement are major ecological problems Most A's are B ≠ Most B's are (most Senators are men ≠ most men are Senators) This answer was definitely worth looking into, but technically it still doesn't tell us about our New Idea in the conclusion: few/most serious ecological problems We specifically need the few/most attached to "serious/major ecological problems".

  5. Wrong Direction12% picked this

    Few serious ecological problems can be solved by major changes in

    This tells us that most serious ecological problems can't be solved by major changes in consumer habits. We're trying to prove a conclusion that "most serious ecological problems require economically enticing solutions". The only way we have to establish that something requires economically enticing solutions is if we first establish that something requires major changes in consumer habits. In other words, it would be a correct answer to be told Most serious ecological problems require major changes in consumer habits. This answer, meanwhile, tells us that Most serious ecological problems cannot be solved by major changes in consumer habits. So this answer is not giving us an idea we can use to derive the conclusion.
