Logical reasoning PrepTest 126 · Section 4 · Question 11

Incorrect. Inez thinks the book title should reflect all of a book's content. Only half the book discusses energy, so this title would also miss the mark according to her principle.

Incorrect. Antonio thinks that matter and energy are facets of the same phenomenon, but that leaves open them being different in some ways. After all, it's hard to be distinct facets if two things are identical.

Incorrect. Inez thinks energy and matter are closely related subject[s]." Antonio thinks they're facets of the same phenomenon. Both believe that they're related, so this isn't a point of disagreement as this answer states.

Incorrect. The two disagree over the title; neither mentions the value of the book.

Correct. Argument or Facts:
Argument/Argument

Valid or Flawed:
Flawed/Flawed

Question Type:
Must Be True

Stimulus Summary:
I: Book titles should reflect content. The Nature of Matter is about both matter and energy, which are related but distinct, so it's mistitled.

A: Physics says energy and matter are facts of the same thing, so it's not mistitled.

Answer Anticipation:
This stimulus is set up much more like a Point at Issue/Point of Agreement question than a Must Be True question, but the question stem definitely introduces a Must Be True question. Interestingly, some of the answers end up bringing us back to this being a Point at Issue/Point of Agreement question in framing the answer as it being true that the speakers dis/agree on certain topics! Whatever the case, we need to understand both speakers's statements so we can analyze the answers.

Inez brings up a principle—book titles should reflect content. She then applies it to a specific book—The Nature of Matter talks about both matter and energy, which are related but different. From this, she concludes the book title doesn't reflect all the content and thus it is a bad title.

Antonio brings up what modern physics believes—energy and matter and both facets of the same phenomenon, so the book isn't mistitled. He seems to think that energy and matter are more similar than Inez does, but he still thinks there's some difference between them as he refers to them as distinct facets of the same phenomenon.

With this understanding, let's head to the answers to see which one lines up with this information.

Answer Explanation:
Inez believes a book's title should reflect all the content in it, and since the book speaks about both matter and energy, it should have both in the title. This answer is thus supported by the statements and so it's correct. Note that it doesn't discuss or rely on Antonio's statements at all, which is fine in a Must Be True question—the correct answer just needs to be supported, not comprehensive.
Key Takeaway:
The question type is determined by the question stem. If a question has some elements of another question type, you can use what you know about that question type to help you in your analysis. But at the end of the day, make sure the answer you select addresses the actual question asked. Here, despite there being many elements that made this question similar to a Point at Issue/Point of Agreement question, it was a Must Be True question. Treating it as a Point at Issue/Point of Agreement question would have led you to dismiss the correct answer since it only brought up what one of the speakers said.
