Passage

In the absence of international statutes prohibiting nations from causing each other environmental damage, scholars of international environmental law typically focus on trying to identify and clarify norms of “customary international law”: that body of commonly accepted—but not formalized—legal principles that is manifest in the behavior of nations toward one another. Two nations to exercise due care to avoid putting other nations at significant risk of environmental harm.

In debating whether a given principle should be classified as a norm of customary international law for the purposes of deciding international cases, scholars of international environmental law generally accept an established criterion: principles are norms only if nations customarily abide by the principles in actual practice rather than merely affirming them constantly cross most international borders, and that nations have only rarely attempted to remedy this situation.

Even though nations only rarely abide by these environmental “norms,” they nevertheless routinely profess to accept them. Similarly, while scholars discussing customary international law claim to focus on what nations do, their debates are almost invariably based on what nations profess. In reality, international environmental “norms” primarily reflect the evaluative standards that characterized as an ideological system, since they merely represent some collective ideals of the international community.

In light of this fact, those scholars who seek in customary international law a firm grounding for decisions in international environmental cases are misdirecting their efforts. This is especially true given that international treaties and direct negotiations, rather than international court decisions, are now the principal means of resolving international environmental disputes. would promote progress toward agreements that could effectively hold nations to appropriate standards of environmental conduct.

The question
26.

The author’s mention of harmful pollutants crossing international borders (last sentence of the second paragraph)

Answer choices, explained

  1. Wrong Contention4% picked this

    an example of the author’s contention that debates concerning customary international law put too little

    This sentence is an example of the author's contention in the 2nd to last sentence of the 2nd paragraph. purported norms such as the duty to prevent transboundary harm do not reflect the actual behavior of many nations. This answer says it was supporting a contention that "debates put too little emphasis on environmental issues".

  2. Wrong Suggestion12% picked this

    a means of suggesting that stronger enforcement of existing international environmental

    This sentence is a means of suggesting that purported norms such as the duty to prevent transboundary harm do not reflect the actual behavior of many nations. This answer says it's a means of suggesting that "stronger enforcement of existing laws is needed".

  3. Wrong Claim15% picked this

    evidence offered by the author in support of the claim that treaties and negotiations are largely ineffective

    This sentence is evidence offered by the author in support of the claim that purported norms such as the duty to prevent transboundary harm do not reflect the actual behavior of many nations. This answer says it was supporting the idea that "treaties and negotiations are largely ineffective in protecting the environment".

  4. Out of Scope: concerns are justified6% picked this

    an acknowledgment that, in spite of the author’s general disagreement with certain scholars mentioned earlier in the second paragraph,

    This answer doesn't look anything like what we're looking for, which is the 2nd to last sentence of the 2nd paragraph. purported norms such as the duty to prevent transboundary harm do not reflect the actual behavior of many nations. Additionally, this answer is just making up "environmental concerns of certain scholars". The passage never identified what these scholars' environmental concerns were. It was just describing how they attempt to justify their arguments in international environmental cases by using principles that they claim qualify as norms.

  5. Correct62% picked this

    support for the author’s claim that certain international environmental principles do not meet a criterion for being considered

    Why this is right

    This sentence is support for the author's claim that purported norms such as the duty to prevent transboundary harm do not reflect the actual behavior of many nations. This answer says it was supporting the idea that "certain international environmental principles (the duty to prevent transboundary harm) do not meet a criterion for being considered norms (it must reflect the actual practice of nations not just what they affirm as desirable standards)." This brings in more of the overall main point of the 2nd paragraph. Scholars treat "transboundary / precautionary" as principles that qualify as norms of customary international law. To be a norm, you must reflect actual practice of nations. The author says, "actual nations do NOT behave this way. Check it out -- experience shows that harmful pollutants constantly cross most international borders".
