The question

Which one of the following most logically completes

Answer choices

  1. Out Of Scope: “pollution” / Opposite8% picked this

    all nations become less concerned with pollution than with the economic burdens

    We need countries to care less about the economic burden (lower GNP) and more about the CO2 buildup (which is not really the same as pollution). So this answer is both opposite and drifting from the topic at hand by going from talking about a CO2 buildup to talking about pollution.

  2. Out Of Scope: “multinational corporations”12% picked this

    multinational corporations agree to voluntary strict

    This actually does seem like a possible solution. It loses out to choice C because it comes out of nowhere. Logical Completion is about pulling together the two strands of the conversation. This doesn’t combine the ideas of the 2nd and 3rd sentences.

  3. Correct77% picked this

    international agreements produce industrial emission

    Why this is right

    Since no country wants to singlehandedly sacrifice its GNP in order to lower fossil fuel emissions (since doing do benefits everyone), we need multiple countries to agree to do it at the same time. This answer is better than B because this one addresses the tension cited that countries don’t want to embark on emission standards singlehandedly.

  4. Too Strong2% picked this

    distrust among nations is

    Too Strong: “eliminated” / Out Of Scope: “distrust” The paragraph wasn’t saying that countries distrust each other. It was just pointing out the normal human nature idea of, “Why should *I* be the only one doing the work, if everyone is going to benefit?” Even if distrust were eliminated and all countries trusted each other, it would still be true that none of them would want to singlehandedly try to lower emissions in order to abate global CO2 buildup.

  5. Too Strong: “establish a world government”2% picked this

    a world government is

    This is close to reinforcing the idea of, “We’re only gonna solve this problem if we work together”. But we don’t need a world government in order to work together. Choice C is a much more moderate suggestion of how countries work together. The idea that we need to create a world government in order to get multiple countries to reduce fossil fuels at the same time is too much of a reach, too exotic of a solution.
