What this topic is asking
Topic 1.2 (skill CLE-2.A) asks you to explain how reasoning, which the AP rubrics call commentary, connects evidence to the claim it supports. Evidence never speaks for itself. The writer's job, and yours on the essays, is to explain why the evidence proves the claim. Commentary is where most of the marks live.
What commentary is
Think of an argument as three parts: a claim, the evidence, and the commentary that bridges them. Skip the bridge and the reader is left to guess how the evidence is supposed to help. The bridge is also where a writer reveals their thinking, which is why it is the most analysable part of any argument.
Why evidence cannot stand alone
A statistic like "turnout rose 18 percent" is just a number until someone interprets it. One writer could use it to argue that barriers, not apathy, suppress voting; another could argue that the change was caused by a contested election. The evidence is the same; the commentary makes the argument.
Summary versus commentary
The most common failing is summarizing evidence instead of analyzing it. Summary repeats what the evidence says; commentary explains what it does.
- Summary: "The writer says the city is loud."
- Commentary: "By cataloguing the city's noise in a breathless, comma-spliced list, the writer makes the reader feel the exhaustion of urban life, so that the later call to slow down arrives as relief."
The second sentence interprets a choice and ties it to effect and purpose. That is what the rubric rewards.
Why this matters for the exam
All three free-response essays - synthesis, rhetorical analysis, and argument - put four of six points on evidence and commentary. Multiple choice questions ask you to identify which sentence is commentary versus evidence. The skill is identical across the exam: explain the link, do not just supply the parts.

Q1. In one sentence, define commentary and state the questions it answers. [Recall]
- Cue. Commentary is the reasoning that links evidence to a claim; it answers "so what?" and "how does this evidence support the point?"
Q2. A student writes: "Crime fell 12 percent." Add one sentence of commentary that turns this evidence into part of an argument that the new policing strategy worked. [Short explanation]
- Cue. For example: "This double-digit drop, beginning the month the new strategy launched, suggests the change in tactics - not chance - drove the decline, which is exactly what the policy promised."
Exam-style practice questions
Practice questions written in the style of College Board exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
AP 2024 (multiple choice, style)1 marksA student writes: 'Voter turnout rose 18 percent after the city opened weekend polling. This shows that removing practical barriers, not apathy, was suppressing participation.' The second sentence functions as (A) additional evidence (B) a counterclaim (C) commentary that interprets the evidence (D) a claim of value (E) the rhetorical situation.Show worked answer →
Answer: (C). The skill is distinguishing commentary (the reasoning) from the evidence it interprets.
The first sentence is statistical evidence; the second sentence tells us what the statistic means and why it matters ("removing practical barriers, not apathy"). That interpretive move is commentary.
Why not the others: (A) it adds no new data; (B) it does not raise an opposing view; (D) it is reasoning about evidence, not a standalone value judgement; (E) it has nothing to do with audience or occasion.
Markers reward recognizing that commentary is the link, not the proof itself.
AP 2021 (rhetorical analysis, style)6 marksThe passage below is from an essay arguing that cities should slow down. Read it carefully. Then write an essay analyzing the rhetorical choices the writer makes, ensuring that your own commentary explains the effect of each choice rather than merely identifying it.Show worked answer →
Free Response Question 2 (rhetorical analysis), 6-point rubric (1 thesis, 4 evidence and commentary, 1 sophistication). The 4-point evidence-and-commentary band is where commentary skill is rewarded directly.
To earn the upper half of the rubric you must move past identifying devices. For each quoted choice, write commentary that explains its EFFECT on the audience and how it advances the writer's purpose.
Weak: "The writer uses a metaphor of the city as a machine." Strong: "By recasting the city as a machine that has overheated, the writer frames urban speed as a malfunction, making the reader feel that slowing down is a repair, not a sacrifice."
The difference between a mid-range and a high score is almost always the quality of commentary, not the number of devices spotted. That is why interpreting evidence, not just citing it, is the central skill.
