Question Type

Argument Completion Questions

Answer choices

  1. A
    nations that have knowledge Remaining source text redacted.
    Why choice A is not credited
    Incorrect. This answer is the negation of the argument, which talks about understanding needs/problems as a necessary condition for justice, not a sufficient one.
  2. B
    without some interaction, nations Remaining source text redacted.
    Why choice B matches the stem
    Correct. Argument or Facts:
    Facts

    Question Type:
    Argument Completion

    Stimulus Summary:
    Nations that don't interact don't know the needs/problems of each other, and sympathy/justice depends on knowing this, so __________.

    Answer Anticipation:
    If sympathy and justice depend on knowing the needs and problems of others, and nations that don't interact much with each other don't know the needs and problems of each other, then they can't have sympathy or justice for each other.

    Answer Explanation:
    This answer matches our anticipation. If sympathy/justice require understanding needs and problems, and understanding needs and problems requires interaction, then a lack of interaction means a lack of sympathy/justice, as this answer states.

    Key Takeaway:
    Argument Completion questions generally bring all the statements from the stimulus together. If answers seem to deal with only a part of the stimulus, it's unlikely to be correct.
  3. C
    almost all problems between Remaining source text redacted.
    Why choice C is not credited
    Incorrect. There's no discussion in the stimulus of problems between nations, so this answer is out of scope.
  4. D
    there is no way Remaining source text redacted.
    Why choice D is not credited
    Incorrect. First, conflict between nations is unmentioned and out of scope. Second, this answer is strong—it's rare that an answer saying something is impossible will be correct.
  5. E
    only nations that have Remaining source text redacted.
    Why choice E is not credited
    Incorrect. This is essentially the contrapositive of the first sentence, so it's unlikely to serve as the conclusion of the entire argument (and it doesn't add much).
