SAT Reading — Text Structure and Function Questions

What These Questions Ask

Text structure questions ask you to identify how a passage is organized or what role a specific sentence plays within the passage.

Common question stems:

  • "Which choice best describes the overall structure of the text?"
  • "The main function of the underlined sentence is to..."
  • "How does the second paragraph relate to the first?"
  • Two Types: Whole-Passage vs. Sentence-Level

    Whole-passage structure questions ask about the organization of the entire text. Common structures:

  • Claim → Evidence: Author makes an argument, then supports it with evidence
  • Problem → Solution: Describes a problem, then presents a way to solve it
  • Compare and contrast: Shows similarities and differences between two things
  • Chronological: Events presented in time order
  • Cause and effect: Explains why something happened and what resulted
  • Sentence-level function questions give you one sentence (usually underlined) and ask what it does within the passage. The sentence might:

  • Introduce the main idea (thesis)
  • Provide a specific example to support a broader claim
  • Transition from one idea to another
  • Acknowledge a counterargument (concession)
  • Return to the main point after a digression
  • How to Approach Structure Questions

    For whole-passage structure: 1. Identify what the passage opens with (claim? problem? background?) 2. Identify what the passage does in the middle (evidence? counterargument? explanation?) 3. Identify how it ends (conclusion? solution? implication?) 4. Pick the answer that accurately describes all three parts

    For sentence-function questions: 1. Read the sentence in its full context (sentence before it + sentence after it) 2. Ask: what is the purpose of this sentence in relation to what comes before and after? 3. Eliminate answers about what the sentence says — you want answers about what it DOES

    Real-world example: A passage opens by describing how ancient civilizations believed in flat earth cosmology. The second paragraph presents Pythagoras and Aristotle's evidence for a spherical earth. The final paragraph notes that despite this evidence, flat earth belief persisted for centuries. A structure question might ask: "Which choice best describes the overall structure?" The correct answer: "The text describes an early misconception, presents evidence that challenged it, and then notes why the misconception persisted." Wrong answers would mischaracterize any of these three parts.

    Key Terms

  • Text structure: How a passage is organized (claim-evidence, problem-solution, chronological, compare-contrast, cause-effect)
  • Sentence function: The role a specific sentence plays in the passage (introduces, provides example, transitions, concedes, concludes)
  • Claim: The author's main argument or position
  • Evidence: Details, examples, or data that support the claim
  • Concession: An acknowledgment that the opposing view has some merit; usually followed by a "but" or "however"
  • Transition sentence: A sentence that moves the passage from one idea to another

Quiz Questions:

Q1. A passage first describes how scientists once believed the universe was static and unchanging. The second half presents evidence from Edwin Hubble's observations that galaxies are moving away from each other, suggesting an expanding universe. Which choice best describes the overall structure?

A) The text presents a scientific claim, then immediately contradicts it without evidence B) The text describes a previously held belief, then presents observational evidence that challenged it C) The text compares two competing theories without taking a position D) The text presents a problem facing modern astronomy and proposes a solution

Answer: B — The passage follows a "prior belief → new evidence" structure. The first part presents the old view (static universe); the second part presents Hubble's evidence (expanding universe). Choice A is wrong because evidence IS presented. Choice C is wrong because the passage clearly favors the new view. Choice D is wrong because there is no "problem to solve."

Q2. A passage argues that remote work increases productivity. The third sentence reads: "Critics argue that remote workers are more easily distracted at home than in an office setting." What is the function of this sentence?

A) To introduce the main argument of the passage B) To provide statistical evidence for the author's claim C) To acknowledge a counterargument before the author responds to it D) To conclude that remote work is not beneficial

Answer: C — This sentence presents the opposing view (critics say remote workers are distracted). This is a concession or counterargument that the author likely addresses in the next sentence. It doesn't introduce the main claim (A), provide data (B), or conclude against the thesis (D).

Q3. The following sentence appears midway through a passage about climate change: "These alarming projections, however, have been met with both urgency and skepticism by policymakers worldwide." The primary function of this sentence is to:

A) Provide specific climate data B) Serve as a transition that introduces a discussion of the varied policy responses to climate projections C) Conclude the passage by summarizing the main argument D) Undermine the author's earlier claims about climate science

Answer: B — The sentence introduces a new dimension (policy responses), and the word "however" signals a shift. It's a transitional sentence that moves from the scientific projections discussed earlier to the political reception of those projections.

Q4. A student notices that a passage opens with a compelling anecdote about a single patient and then broadens to discuss a nationwide health trend. The function of the opening anecdote is most likely to:

A) Provide statistical data to support the main argument B) Humanize and contextualize the larger trend being discussed, making it personally relatable C) Contradict the main argument of the passage D) Establish the credentials of the author

Answer: B — Opening anecdotes are used to create an emotional connection and illustrate the larger issue in a personal, concrete way before broadening to the statistical or analytical claim. They don't provide stats (A) or contradict the argument (C).

---

Q5. A passage ends with: "Whether or not policymakers heed these warnings, the evidence suggests that the window for meaningful action is narrowing." What is the function of this final sentence?

A) To introduce a new argument the author has not yet discussed B) To restate the main thesis and emphasize the urgency of the issue as a conclusion C) To concede that the author's earlier argument was flawed D) To provide specific data about policy outcomes

Answer: B — A final sentence that references "evidence" and emphasizes urgency serves as a conclusion that reinforces the passage's main argument. It doesn't introduce new ideas (A), undermine the argument (C), or provide data (D).
