Answer choices

  1. A
    It is the conclusion Remaining source text redacted.
    Why choice A matches the stem
    Correct. Argument or Facts:
    Argument

    Valid or Flawed:
    Valid

    Question Type:
    Argument Structure

    Stimulus Summary:
    People are polite to each other → Society improves
    Enforcing laws requiring politeness would create more problems than impoliteness
    Therefore, laws requiring politeness won't improve society

    Answer Anticipation:
    The first statement sets up a conditional rule that establishes what would happen to society with a given change. Since it's a prediction, there's a chance it's the main point. However, the next sentence immediately pivots away from it ("But") to the statement in question. This is a competing prediction, so since the argument pivots to it and it's a prediction, it's likely the main point of the argument. That's backed up by the following statement explaining why it's true, thus serving as a premise.

    The correct answer should highlight that it's the conclusion of the argument, and if there's more than one answer stating that it's the conclusion, then we should look for one that says it puts a limitation on the opposing point (politeness will help society as long as it's not mandated).

    Answer Explanation:
    This answer reflects that the statement is a pivot away from one prediction, limiting it, that has support in the final sentence.

    Key Takeaway:
    Always note pivot words—they define when the author shifts away from an opposing point or a premise that she's not generally going to rely on in reaching the main point. Also, predictions tend to be conclusions, even when they're conditional.
  2. B
    It is cited as Remaining source text redacted.
    Why choice B is not credited
    Incorrect. The argument doesn't make sense with this second sentence serving as a premise for the final sentence, so it can't be a premise.
  3. C
    It is cited as Remaining source text redacted.
    Why choice C is not credited
    Incorrect. This answer describes an argument with an intermediate conclusion. Since there are only two statements making up the author's argument (the first being an opposing point), this can't be correct.
  4. D
    It is cited as Remaining source text redacted.
    Why choice D is not credited
    Incorrect. This answer, again, brings up an argument with three pieces, and the author's argument has only two (discounting the opposing point, which isn't a part of the author's argument).
  5. E
    It describes a phenomenon Remaining source text redacted.
    Why choice E is not credited
    Incorrect. The phenomenon is actually unstated—the current state of society and the level of impoliteness.
