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

Question Type

Parallel Reasoning Questions

Answer choices

  1. A
    No actor represented by Remaining source text redacted.
    Why choice A is not credited
    Incorrect. Before diagramming, we can eliminate this answer choice because of a term shift between the premise about a "major" movie and the conclusion about all movies.
  2. B
    No hotel owned by Remaining source text redacted.
    Why choice B is not credited
    Incorrect. Owned by Bidmore → not Specializes in business travelers
    CSP → Owned by Bidmore
    Therefore, CSP → not Specializes in business travelers
    This is a valid argument that arguably builds from two conditionals, but it doesn't have the timeline of the original argument ("Last year") and it also doesn't rely on a contrapositive. This would survive a first pass but have a strike against it that would eliminate it after working on the correct answer.
  3. C
    Pranwich Corporation has never Remaining source text redacted.
    Why choice C matches the stem
    Correct. Argument or Facts:
    Argument

    Valid or Flawed:
    Valid

    Question Type:
    Parallel Reasoning

    Stimulus Summary:
    Nonfiction → not Earned profit
    Book from last year → Earned profit
    Therefore: Book from last year → not Nonfiction

    Answer Anticipation:
    Working a bit to get the elements lined up, we get:

    Book from last year → Earned profit
    Earned profit → not Nonfiction
    Therefore: Book from last year → not Nonfiction

    That's a valid conclusion building off of two conditional statements, so let's head into the answer choices and eliminate ones that don't line up.

    Answer Explanation:
    Employee in P's marketing division → not Bonus
    Systems analyst last year → Bonus
    Therefore: Systems analyst last year → not Employee in P's marketing divisionThis argument is valid, has the same timeline element as the stimulus, and combines two conditionals after taking the contrapositive of one. That checks all the boxes, so this is the correct answer.

    Key Takeaway:
    It's completely normal to have a Parallel Reasoning question where the base diagram ends up looking a lot like more than once answer choice—especially on the harder questions later in the section. When that happens, narrow it down and then identify other relevant elements of the stimulus that match up with only certain answers. Think back to other questions for what elements might be relevant—we've seen timelines be relevant in other questions, so looking for answers that share that aspect of the stimulus reflects what we know about important logic on the test.
  4. D
    James Benson has never Remaining source text redacted.
    Why choice D is not credited
    Incorrect. James Benson → not Done business with Waldville
    Waldville file → Done business with Waldville
    Therefore: James Benson → not Waldville file
    First off, it's a bit of a stretch to call some of these statements conditionals. That said, there's no timeline established in this answer choice, as there was in the stimulus.
  5. E
    Conway Flooring has never Remaining source text redacted.
    Why choice E is not credited
    Incorrect. Without even diagramming this answer out, you should be able to tell it's flawed. It bases a very strong conclusion—they "do[] not" install hardwood flooring—based on a weaker premise—"a lot of" customers they haven't installed hardwood flooring for.
