Question Type

Principle Questions / Strengthen Questions / Sufficient & Necessary Questions

Answer choices

  1. A
    Only if a measure Remaining source text redacted.
    Why choice A is not credited
    Incorrect. This answer provides a necessary condition for adopting a policy ("only if . . . should it be adopted"). Since the conclusion is that we should adopt a policy, we need an answer that provides a sufficient condition for doing so.
  2. B
    Only if a measure Remaining source text redacted.
    Why choice B is not credited
    Incorrect. This answer provides a necessary condition for adopting a policy ("only if . . . should it be adopted"). Since the conclusion is that we should adopt a policy, we need an answer that provides a sufficient condition for doing so.
  3. C
    If a measure is Remaining source text redacted.
    Why choice C matches the stem
    Correct. Argument or Facts:
    Argument

    Valid or Flawed:
    Flawed

    Question Type:
    Strengthen (Principle)

    Stimulus Summary:
    Solving homelessness → Government provides housing
    Government provides housing → Increase taxes
    Therefore - We should raise taxes

    Answer Anticipation:
    Strengthen (Principle) questions tend to present judgments in the conclusion backed up by details in the premises. Here, the conclusion takes the form of a recommendation—we should raise taxes.

    Why does the Politician take this unpopular stance? Because raising taxes is necessary to provide housing to the homeless, which is necessary in solving the homeless problem. So, in other words, we should raise taxes because we need to to solve the homelessness crisis.

    Let's find an answer justifying that logic.

    Answer Explanation:
    This answer reflects the logic in the stimulus. Raising taxes is necessary to solve homelessness. This answer establishes that if a measure is so required, then it should be adopted. The conclusion is justified based on this, so it's the correct answer.

    Key Takeaway:
    Note that we were able to throw out a lot of these answers because they mixed up sufficient and necessary conditions. Know how these elements of conditional statements line up with arguments (and question types) so that you can make the same eliminations quickly!
  4. D
    If a measure is Remaining source text redacted.
    Why choice D is not credited
    Incorrect. The stimulus doesn't establish that raising taxes is sufficient in solving homelessness, but rather that it's necessary to do so.
  5. E
    If a measure is Remaining source text redacted.
    Why choice E is not credited
    Incorrect. The stimulus doesn't establish anything as being sufficient in solving homelessness, just some things that are necessary.
