Evidence and Commentary
Integrate evidence smoothly and write commentary that explains how details support a larger interpretive or argumentative claim.
A lesson of English 12, in College Composition, about 10 minutes.
By the end of this lesson, you will be able to select the most effective evidence for a claim, write commentary that goes beyond paraphrase to genuine analysis, and sustain analytical momentum across a full paragraph.
The Ratio Rule — Revisited
At the college level, the ratio of commentary to quotation should be higher than in high school — roughly 4:1 (four sentences of your analysis for every one sentence of quotation).
This ratio is not arbitrary: it reflects the relative weight of your argument vs. the evidence. You are not presenting evidence and hoping your reader will interpret it correctly; you are controlling the interpretation.
Selecting the Most Effective Evidence
Not all evidence is equal. At the college level, you should be selecting evidence that:
- Requires interpretation — not evidence whose meaning is obvious
- Is specific — a particular word, image, or moment, not a general scene
- Is surprising or counterintuitive — the expected passage proves less than the unexpected one
- Yields multiple levels of analysis — the word choice, the placement, the figurative language all contribute simultaneously
Four Levels of Commentary
Level 1 (paraphrase): What does the evidence say? (NOT sufficient alone)
"In this passage, the narrator describes the room as dark and cold."
Level 2 (characterization): What does the evidence reveal about a character or situation?
"The description of darkness and cold signals the narrator's emotional isolation."
Level 3 (formal analysis): What does the author's specific choice (word, structure, image) contribute?
"The clinical precision of 'dark and cold' — words with zero figurative ornamentation — is itself the point: the narrator lacks the emotional capacity to color the room with meaning. It is rendered in the flat prose of report, not experience."
Level 4 (thematic synthesis): How does this moment advance the larger argument?
"This moment of sensory numbness is the novel's early warning that the narrator's detachment will eventually make them incapable of the very connection they claim to want."
The strongest commentary reaches Level 3 and 4 consistently.
Sustaining Analytical Momentum
A common problem: strong commentary on one piece of evidence, then the paragraph introduces another piece and the analysis resets to Level 1.
The solution: each new piece of evidence should add to the argument, not repeat it. The commentary should build.
