Question prompt

All poets, aside from Remaining source text redacted.
Why the credited answer is right

Credited answer: E

The notes below walk through why it fits the stem and how to eliminate the rest.

Question Type

Parallel Reasoning Questions / Sufficient & Necessary Questions

Answer choices

  1. A
    All squeeze toys, except Remaining source text redacted.
    Why choice A is not credited
    Incorrect. Squeeze toy AND not Designed for cat → Safe for infants
    Squeeze toy → . . . and we're out. In the original, the second conditional statement had a new term as a sufficient condition.
  2. B
    Aside from the dogcatcher Remaining source text redacted.
    Why choice B is not credited
    Incorrect. There are two exceptions to the conditional rule here, so we can rule this answer choice out immediately.
  3. C
    All visas are assigned Remaining source text redacted.
    Why choice C is not credited
    Incorrect. Visa AND not Issued through diplomatic channels → Assigned by this office
    Visa permit → Visa br /> . . . And we're out. This answer goes straight into the conclusion without establishing a nonconditional premise.
  4. D
    All of this store's Remaining source text redacted.
    Why choice D is not credited
    Incorrect. Winter garment AND not Designer → Sale
    Shirt → not Designer . . . and we're out. The second conditional didn't connect to the exception to the rule.
  5. E
    All residential buildings are Remaining source text redacted.
    Why choice E matches the stem
    Correct. Argument or Facts:
    Argument

    Valid or Flawed:
    Valid

    Question Type:
    Parallel Reasoning

    Stimulus Summary:
    Poets AND not Only epigrams → Wit
    Lyrical composer → Poet
    Azriel: not Only epigrams AND Lyrical composer
    Therefore: Wit

    Answer Anticipation:
    This Parallel Reasoning question is all about the conditional logic, so let's take some time to make sure we got it right.

    That first statement brings up a conditional that has an exception. Exceptions to a rule highlight the only place where the rule breaks down. In other words, the rule applies to all scenarios where the exception doesn't happen. That's why we diagrammed the rule the way we did—if you're a poet and you don't fall into the exception, then the rule applies and you have wit.

    The next statement is straightforward, but the next statement about Azriel we changed up a bit. It states that he does not write epigrams, which guarantees that he doesn't write only epigrams, and we diagrammed it out to match with the conditional rule.

    With that done, we can see that this argument is valid, and it takes the form:
    A AND B → C
    D → A
    B and D
    Therefore: C

    We should look for that first conditional rule with an exception to hopefully make some quick eliminations, and then we'll have to work through the rest of the arguments to see if they match up.

    Answer Explanation:
    Residential building AND not Built last year → Original fire code
    Townhouse → Residential building
    Bloom House: Townhouse AND not Built last year
    Therefore: Original fire code
    This answer mirrors the original, so it's correct.

    Key Takeaway:
    When you're dealing with a Parallel Reasoning question that features conditional logic, it can be helpful to identify elements that will be quick to spot and can be used to make eliminations—quantifiers and AND/OR statements, in particular. Unfortunately, as here, this will sometimes not lead to many eliminations. When you have to work through the diagram for the answers, be sure to jump out as soon as you can find a mismatch to save time.
