Passage Summary

Topic: Science


Paragraph 1

  • Paragraph note
    • Some thinkers on scientific explanation (math is a language that can describe the physical world)
  • Views, minor Meta-Structures, and the author's attitude
    • "Some thinkers'" view:
      • Math is a language that you use to describe some aspect of the physical world (second and third sentences)
      • The language is evaluated by how coherent it is and how well it describes reality (second sentence)
    • Cause-and-effect relationship, according to "some thinkers":
      • Applying math to the physical world causes the creation of a statement about the world (third sentence)

Paragraph 2

  • Paragraph note
    • A similar debate in linguistics (is language solid or just arbitrary conventions?)
  • Views, minor Meta-Structures, and the author's attitude
    • Comparisons, according to the author:
      • The questions about scientific knowledge in paragraph 1 are similar to linguists' debate on the relationship between language and reality (second sentence)
      • The two sides of the linguists' debate differ over whether language refers to reality in an essential, dependable way or is just a matter of agreed-upon conventions that can change over time (last sentence)
    • Author's attitude: "at the center of the issue" (first sentence), "can thus be found" (first sentence)

Paragraph 3

  • Paragraph note
    • Expanding on one side of linguists' debate (statements are only true if there aren't better alternatives) and applying it to the sciences
  • Views, minor Meta-Structures, and the author's attitude
    • Views of linguists who think language is just arbitrary conventions:
      • Gaining more popularity (first sentence)
      • Language is dependent on the practices and theories of those who use it (second sentence)
      • A statement is only true when there are no promising alternatives (third sentence)
    • Comparison, according to the author:
      • The linguists' views are applicable to the sciences because some say mathematical statements are similarly arbitrary and are only "true" until a better statement can take its place (fourth through last sentences)
    • Cause-and-effect relationship, according to the author:
      • The scientific community accepting a mathematical statement causes the "analogy/metaphor" math provides to be held true (last sentence)
    • Author's attitude: "wider acceptance" (first sentence), "Certainly this characterization would seem to be applicable" (fourth sentence)

Paragraph 4

  • Paragraph note
    • Author on the question sciences must ask (what do mathematical models actually provide in gaining knowledge?)
  • Views, minor Meta-Structures, and the author's attitude
    • Comparison, according to the author:
      • In the course of their debate, linguists have encountered an important question: if language is truly arbitrary, what is its role in the pursuit of knowledge? (first sentence)
      • The sciences have not yet applied this question to their field, but they should (second and last sentences)
    • Author's attitude: "they must ask" (first sentence), "equaly necessary to ask" (second sentence), "yet to be significantly addressed" (third sentence)

Main Point: Scientists should look to the debate amongst linguists about the relationship between language and reality to understand the nature of mathematics and its correspondence with reality.

Key Lines?

Paragraph 2, Sentence 1 (P2, S1): The question is posed (what is the relationship between scientific language and reality?)

P4, S1: The author's directive

Meta-Structure?

Question/Answer: This passage utilizes a Question/Answer Meta-Structure. In such a structure, the author describes a question and (sometimes) an answer.

The first paragraph of this particular passage sets the stage, introducing us to the link between language, math, and the physical world. According to some, math (like language) can be thought of as an artificial system that sets out to describe how the world works. Then, the second paragraph describes a question at the center of scientific knowledge: what is the nature of the relationship between mathematical language and the reality it seeks to describe. The author relates this issue to a debate happening in linguistics about whether language is completely arbitrary or if it corresponds to reality in some essential way.

In the third paragraph, the author explains the former position (that holds language is arbitrary) and applies it to the question in the scientific community, demonstrating how it aligns with how some people utilize mathematical statements. In the fourth and final paragraph, the author points out an important question that linguists have arrived at: if language is truly arbitrary, what is its role in the pursuit of knowledge? The author thinks that scientists need to apply this question to their own field.

The Question/Answer Meta-Structure is ultimately the best fit because the "the issue of scientific knowledge can thus be found questions about the relationship between language and what it refers to" (P2, S1) is the "question" that the passage addresses. Now, the author's answer to this question is more difficult to identify. While the author never lands on a concrete answer, they indicate a direction of thought that could be helpful: scientists should approach the question as linguists do. The author thinks this connection is important, but they do not say that it's enough to resolve the debate. Since the author focuses on the application of the linguists' debate, we should include it in our main point.

In passages that utilize a Question/Answer Meta-Structure, the main point will generally be the author's opinion on possible answers to the question. As we just determined, this author doesn't settle on a concrete answer but rather indicates a way to approach the question. Therefore, we can anticipate a main point that says something like this: "Scientists should look to the debate amongst linguists about the relationship between language and reality to understand the nature of mathematics and its correspondence with reality."

Comparison: The most prominent minor Meta-Structure in this passage is the comparison. One could even argue that this so-called "minor" Meta-Structure is even more important than its "major" counterpart. The entire passage hinges on the author's comparison of science and linguistics. The author argues that both fields ask similar questions about the relationship between language and reality. When a passage hinges on a comparison between two things, we can expect the author to describe many supporting comparisons along the way. We've catalogued these comparisons in the Passage Summary above, and we can expect at least one of them to figure into a question.

Last Thoughts?

As difficult as this passage is (and, make no mistake, it’s a doozy), the author at least does us the courtesy of summarizing the main point in the last paragraph of the passage. The last three sentences of this passage are the main point, and they should be our lodestar as we work through these difficult questions.

Strategy Overview

Refer to notes or what you highlighted/underlined to locate where the passage discusses why mathematics can be considered a language, and refer to the relevant part of the passage as needed to find that answer choice that must be true

Answer Anticipation

For questions that ask us to find a specific detail mentioned in the passage, quickly finding and reviewing that piece of information is paramount. That is why we make brief notes describing the role of each paragraph and highlight or underline definitions and the minor Meta-Structures — doing so helps us find the salient information efficiently and reliably. Once we review that part of the passage, we can look through the answer choices to see which one is best supported by what we reviewed.Here, the question asks why mathematics can be considered a language. When did the passage discuss that? Our note for the first paragraph is, "Some thinkers on scientific explanation (math is a language that can describe the physical world)." Given that it says "math is a language," we can probably look there! There, we read that some people call math a language because it's “a systematic contrivance of signs” (P1, S2). Let’s see if that’s enough information to select an answer choice.

Answer choices

  1. A
    conveys meaning in the Remaining source text redacted.
    Why choice A is not credited

    (A) Does this say math is language because it's a systematic contrivance of signs?

    Not quite. For that reason, we can eliminate (A) without giving it too much thought.

    That said, some test-takers are nonetheless attracted to (A). The passage does relate mathematical statements to metaphors in the third paragraph (P3, S6), but it does so when applying the conventionalist view of language (which says language is arbitrary) to mathematics. This part of an argument involves the author supposing that linguistic theory could be applied to scientific knowledge. It doesn't involve the author explaining why mathematics is a type of language.

  2. B
    constitutes a systematic collection Remaining source text redacted.
    Why choice B matches the stem

    (B) Does this say math is language because it's a systematic contrivance of signs?

    Yes! This is nearly a word-for-word match for the sentence we located in the first paragraph — the one that says math is a “systematic contrivance of signs” (P1, S2). (B) is definitely our answer. We would be justified in selecting (B) and advancing to the next question.

  3. C
    corresponds exactly to aspects Remaining source text redacted.
    Why choice C is not credited

    (C) Does this say math is language because it's a systematic contrivance of signs?

    No. For that reason, we can eliminate (C) without worring about it too much.

    Still, many test-takers select (C). However, the author says that "there's nothing inherent in mathematical language that guarantees" that math will correspond exactly to aspects of physical phenomena (P3, S5). Because the author doesn't necessarily believe this statement is true, it definitely doesn't describe why math can be considered a language.

  4. D
    confers explanatory power on Remaining source text redacted.
    Why choice D is not credited

    (D) Does this say math is language because it's a systematic contrivance of signs?

    No. So we can cross off (D) without giving it a second thought.

    That said, many test-takers clearly do give (D) a second thought, as it's a very popular selection. Why is it so popular, and why is it wrong?

    Well, (D) appears to reflect the third sentence in the first paragraph. That sentence claims some thinkers believe that you can use math to describe some aspect of the physical world (P1, S3). However, that's not why these thinkers say math is a language. To get that explanation, we'd have to turn to the previous sentence. Further, these thinkers may say that math helps explain the physical world, but they never say that it helps scientific theories explain the world. These might seem like nit-picky reasons to eliminate (D), but they're enough to make (D) wrong, especially on a "According to the passage" Must Be True question.

  5. E
    relies on previously agreed-upon Remaining source text redacted.
    Why choice E is not credited

    (E) Does this say math is language because it's a systematic contrivance of signs?

    No. So we can eliminate (E) without reservation.

    Still, many test-takers like (E). However, this answer choice refers to the linguistics who argue that language is merely a collection of agreed-upon conventions. It doesn't necessarily reflect the views of "some thinkers" who argue that math is a language. So, (E) is unsupported.
