Question Type

Strengthen with Sufficient Premise Questions

Answer choices

  1. A
    Anger is always expressible.
    Why choice A is not credited
    Incorrect. First, it's more of a necessary assumption to say that anger is expressible. Second, this answer doesn't connect the situation to the sufficient condition, so it doesn't allow the conditional to be triggered. Third, the conclusion is that there are always situations where expressing anger is healthy, but that's not the same as saying that it's always healthy to express anger, which is what this answer is pushing towards.
  2. B
    Anger is a visceral Remaining source text redacted.
    Why choice B matches the stem
    Correct. Argument or Facts:
    Argument

    Valid or Flawed:
    Flawed

    Question Type:

    Stimulus Summary:
    Visceral emotion → Situations where it's healthy to express that emotion
    Therefore — There are situations where it's healthy to express anger

    Answer Anticipation:
    The argument presents a conditional ("any" indicating a sufficient condition) and it then concludes the application of that conditional to a particular case (anger). Strengthen with Sufficient Premise questions that apply a conditional to a particular case are usually flawed because they don't establish that the sufficient condition is met in that particular case so we should start by considering that.

    Here the sufficient condition is that an emotion is a visceral one. The specific situation it applies the principle to is anger but it never establishes that anger is a visceral emotion (by definition it is an emotion). The correct answer then should make that connection.

    Answer Explanation:
    If anger is a visceral emotion then the conditional applies to it and we can validly conclude that there are always situations in which it's healthy to express that emotion. This is thus the correct answer.

    Key Takeaway:
    When a Strengthen with Sufficient Premise question works by applying a conditional to a specific case it will usually be flawed in that it fails to establish that the specific case meets the sufficient condition of the conditional. Start your analysis of the logic there! (If that's not the flaw then there's usually a term shift between the necessary condition of the conditional and the conclusion.)
  3. C
    Some kinds of emotions Remaining source text redacted.
    Why choice C is not credited
    Incorrect. The conclusion is that this particular emotion is healthy to express, so other emotions and unhealthy—to—express emotions are all out of scope.
  4. D
    All emotions that are Remaining source text redacted.
    Why choice D is not credited
    Incorrect. This answer is a reversal of the conditional premise, so it's incorrect.
  5. E
    An emotion is visceral Remaining source text redacted.
    Why choice E is not credited
    Incorrect. This answer is more or less a paraphrase of the provided conditional (Visceral emotion → Healthy to express), so it doesn't add anything to the argument, let alone justify the conclusion.
