Question Type

Must Be True Questions

Answer choices

  1. A
    Solving a philosophical paradox Remaining source text redacted.
    Why choice A matches the stem
    Correct. Argument or Facts:
    Facts

    Question Type:
    Must Be True

    Stimulus Summary:
    A philosophical paradox simultaneously feels false but logical. To resolve it, one must accept that either the conclusion is true, a premise is false, or the logic is wrong.

    Answer Anticipation:
    For an anticipation, this is wide open. Spend less time anticipating and more time analyzing the answers!

    Answer Explanation:
    Since a philosophical paradox feels both true and false, and resolving it requires going against intuition, it's going to involve accepting something that feels wrong. If you accept the conclusion as true, it seems to be incorrect since intuition said it was false. If you accept the premise as false, the same thing happens since intuition made it feel true. And the logic seemed solid, so accepting the illogic of it cuts against intuition. This is the answer.

    Key Takeaway:
    For a Must Be True question—especially later in the section—don't feel like you need to anticipate an answer. Sometimes, having a strong understanding of the stimulus is enough, and getting to the answers faster will give you more time to analyze each one.
  2. B
    The conclusion of a Remaining source text redacted.
    Why choice B is not credited
    Incorrect. This is incorrect since a third option is presented—the logic is wrong.
  3. C
    Philosophical paradoxes with one Remaining source text redacted.
    Why choice C is not credited
    Incorrect. The argument doesn't compare paradoxes with differing numbers of premises, so this answer is out of scope.
  4. D
    Any two people who Remaining source text redacted.
    Why choice D is not credited
    Incorrect. Three approaches are mentioned, but there's no mention of the relative likelihood of them being used. It's possible, based on the stimulus, that the vast majority of people who resolve a philosophical paradox do so by believing a premise is false.
  5. E
    If it is not Remaining source text redacted.
    Why choice E is not credited
    Incorrect. Since there are three methods of resolving a paradox and this answer only precludes one of them, it's incorrect to say that the paradox isn't able to be resolved.
