What this topic is asking
Topic 5.6 (skill CLE-1.I) raises commentary, the reasoning that connects evidence to a claim, to the level Unit 5 expects. Earlier topics taught commentary that explains how a piece of evidence supports a claim. This topic asks for commentary that explains the significance of the evidence: why it matters, what is at stake, how it bears on the thesis and the larger argument. This is the "so what" move, and it is the single biggest lever on the evidence-and-commentary score.
Two levels of commentary
The lower level answers "what does this evidence show?" The higher level answers "why does that matter?" Both are commentary, but only the second reliably reaches the upper half of the rubric.
The so-what move
After you explain what evidence shows, push once more: ask "so what?" The answer is the significance. A statistic on falling literacy shows reading is declining (what); the so-what is that a society that reads less loses the shared knowledge it depends on. The second sentence is where the argument's stakes live.
Connecting up and out
Significant commentary connects in two directions. Up, it links the evidence to the claim and the claim to the thesis, so the reader sees how this paragraph advances the whole argument. Out, it links the point to its broader implications, the stakes, consequences, or wider context. Both moves turn an isolated example into part of an argument that matters.
Why this matters for the exam
The evidence-and-commentary band (four points) is the largest on every essay, and commentary depth is what separates its halves. On rhetorical analysis (Question 2), significance means explaining why a writer's choice matters to purpose and audience; on argument and synthesis (Questions 3 and 1), it means explaining why your evidence matters to your position. Significance is also a route to sophistication, since explaining implications is one of the rubric's named sophistication moves.
Try this
Q1. What question does commentary that explains significance answer, beyond "what does this evidence show?" [Recall]
- Cue. It answers "so what?", that is, why the evidence matters, what is at stake, and how it bears on the thesis and the argument's larger implications.
Q2. A student writes: "The report found 40 percent of teenagers sleep under six hours. This shows teenagers are tired." Improve the commentary so it explains significance. [Short explanation]
- Cue. "This shows teenagers are tired" only restates the evidence. A significance-level version: "That so many teenagers run on chronic sleep loss matters because the same years demand peak learning and judgement, so a private health issue becomes a public one about how schools and families are set up, which is precisely why later start times are worth the disruption." It reaches the so-what, connects the data to the thesis, and names the stakes.

AP 2024 (multiple choice, style)1 marksAfter quoting a statistic on falling literacy, a student writes: 'This decline matters because a society that reads less loses the shared knowledge democracy depends on.' This sentence functions as (A) additional evidence (B) commentary explaining the significance of the evidence (C) a counterargument (D) a thesis statement (E) a transition only.Show worked answer →
Answer: (B). The skill is recognizing commentary that explains significance.
The sentence does not add evidence or restate the thesis; it explains why the statistic matters, linking it to a larger stake (shared knowledge and democracy). That is commentary at the level of significance.
Why not the others: (A) it adds no new data; (C) no opposing view; (D) it is narrower than a thesis; (E) it does more than transition, it reasons.
Markers reward commentary that reaches the so-what, not commentary that merely restates the evidence.
AP 2023 (rhetorical analysis, style)6 marksThe passage below builds its argument through carefully chosen evidence. Write an essay that analyzes the writer's choices, taking care that your commentary explains the significance of each example rather than restating it.Show worked answer →
Free Response Question 2 (rhetorical analysis), 6-point rubric (1 thesis, 4 evidence and commentary, 1 sophistication).
The instruction targets commentary quality directly.
Thesis (1 point): claim how the writer's choices achieve the purpose.
Evidence and commentary (4 points): for each quoted choice, explain not just what it does but why it matters to the writer's purpose and the audience's response, the significance, not a paraphrase.
Sophistication (1 point): trace how the significance of the choices accumulates across the passage.
The essay rewards commentary that reaches significance; restating evidence caps the score.
