What this topic is asking
Topic 1.3 (skill CLE-3.B) asks you to build a single, well-formed argument paragraph: one that states a claim, integrates evidence, and uses commentary to relate that evidence to the argument. The paragraph is the fundamental unit of every essay you write, so mastering its structure makes the whole exam easier.
The structure: claim, evidence, commentary
The order is deliberate. The claim comes first so the reader knows what the evidence is meant to prove. The evidence follows. The commentary comes last and should be the longest part, because the reasoning is where you earn marks. A useful shape is claim, evidence, commentary, then a short link back to the thesis or forward to the next paragraph.
Embedding evidence smoothly
How you integrate evidence separates fluent writing from a quotation dump.
- Signal phrases. "As the writer notes," "according to," "Source C observes" introduce the evidence and credit it.
- Quote sparingly. Quote only the words doing the work; paraphrase the rest. The marks are in your commentary, not in the length of the quotation.
- Paraphrase when the wording does not matter. If you need the fact, not the phrasing, restate it in your own words and cite the source.
Relating evidence to the argument
The final move - commentary - is the one students skip when they run out of time, and it is the most valuable.
Why this matters for the exam
All three free-response essays are graded paragraph by paragraph in the evidence-and-commentary band, worth four of six points. Examiners look for complete units: a claim, integrated evidence, and commentary. The synthesis essay specifically rewards integrating source material smoothly rather than block-quoting it. Build clean paragraphs and you build a clean essay.

Q1. Name the three moves of an argument paragraph in order. [Recall]
- Cue. Claim (topic sentence), evidence (integrated), then commentary (reasoning that links evidence to claim).
Q2. Rewrite this dumped quotation so it is embedded: 'Studies prove libraries help. "Library use rose 30 percent."' [Short explanation]
- Cue. For example: "Public records support this: library use rose 30 percent after the late-night hours began, showing that access, not interest, had been the limiting factor." The quotation is woven in and followed by commentary.

AP 2022 (multiple choice, style)1 marksIn a well-built argument paragraph, what is the usual function of the first sentence? (A) to quote a source at length (B) to state the paragraph's claim and connect it to the thesis (C) to provide a statistic without comment (D) to acknowledge the rhetorical situation (E) to restate the introduction word for word.Show worked answer →
Answer: (B). The skill is understanding paragraph architecture: a body paragraph opens with a topic sentence that states its claim and links it to the overall thesis.
Why not the others: (A) and (C) put evidence before any claim, leaving the reader without a point to attach it to; (D) belongs in the introduction; (E) repeats rather than advances the argument.
Markers reward recognizing that a paragraph is a claim-evidence-commentary unit, not a heap of quotations.
AP 2024 (synthesis, style)6 marksRead the following sources on the value of standardized testing. Then write an essay that develops your position, building each body paragraph as a complete unit of argument that integrates source material and explains its relevance.Show worked answer →
Free Response Question 1 (synthesis), 6-point rubric (1 thesis, 4 evidence and commentary, 1 sophistication). Body-paragraph construction is directly tested in the evidence-and-commentary band.
Each paragraph should be a full chain: a claim (topic sentence) that advances the thesis, evidence integrated from at least one source, and commentary that explains how the evidence supports the claim and the position.
Integrate, do not dump. Weave a short quotation or paraphrase into your own sentence ("As Source C notes, 'the test measures preparation, not aptitude,' which means..."). A free-floating block quotation with no lead-in or follow-up does not score.
A paragraph that quotes without a claim, or claims without commentary, leaves points on the table. Building the paragraph as a unit is what earns the upper band.
