SAT Reading & Writing: Explain why an author made a specific structural or stylistic choice

18+ practice questions in Praczo

What you need to know

The concept, explained

  • 1

    These questions ask why the author structured or phrased something a particular way — the goal behind the choice, not the content of the choice.

  • 2

    Common rhetorical purposes: to emphasize, to contrast, to create suspense, to build credibility, to make an abstract idea concrete, to signal a turning point.

  • 3

    Match the choice to the passage's overall goal. A scientist emphasizing uncertainty is probably building credibility, not creating suspense.

  • 4

    Stylistic markers matter: a sudden short sentence often signals emphasis; parallel structure often signals comparison; anecdote often signals accessibility.

  • 5

    Eliminate answers that are factually true about the passage but don't explain the specific choice in question.

Common mistakes
  • Picking an answer that describes what the passage says rather than why the author structured it that way.
  • Overreaching with dramatic purposes ("to shock the reader") when the passage is measured and analytical.
  • Ignoring how the choice interacts with surrounding text — a contrast is only meaningful if something is being contrasted.

SAT-style practice

After three paragraphs of technical explanation about glacier retreat, the author opens the next paragraph with a single short sentence: "The evidence is overwhelming." Why did the author most likely choose to follow the technical paragraphs with this short, direct sentence?
