1.2 Examining how evidence supports a claim

Look for the thesis—the sentence (or sentences) that state the writer’s main position and that require defense. Practically: scan the intro and conclusion for a clear, defensible claim (uses words like should, must, needs, is/are), then check topic sentences in body paragraphs for consistent support. Ask: what exactly is the author trying to prove? Next, map the evidence (facts, stats, anecdotes, expert testimony, examples) to that claim and examine the warrant—the unstated assumption that links evidence to the claim. Also note any rebuttal/counterclaim the writer addresses; a strong main claim anticipates and responds to opposition. For AP free-response, your thesis must be defensible and supported by evidence and reasoning (CED skills 3.A, CLE-1.A/B/C). Want practice?

A claim is the writer’s main position or thesis—a statement that requires defense (CED CLE-1.A). Evidence is the material the writer uses to defend that claim: facts, statistics, examples, anecdotes, expert testimony, experiments, analogies, etc. (CLE-1.C). Think of it this way: the claim answers “What do you want me to believe?” and evidence answers “Why should I believe it?” On the AP exam you must both state a defensible claim (thesis) and select specific evidence to support it, then explain how that evidence connects to your line of reasoning (the warrant)—that’s assessed in multiple-choice and in all three FRQs (see synthesis and argument tasks). For practice identifying types of evidence and explaining how each supports a claim, check the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl) and use Fiveable’s practice problems (https://library.fiveable.me/practice/ap-english-language) to drill this skill.

Writers use lots of evidence types to defend a claim—know these for the AP exam (CED CLE-1.C) so you can ID and explain them in multiple-choice and FRQs. Common kinds: - Facts (verifiable statements) - Statistics (quantitative data) - Examples and details (specific instances) - Anecdotes / personal experiences (short stories illustrating a point) - Personal observations (what the writer has seen/noticed) - Expert opinion / testimony (appeals to authority—ethos) - Analogies (comparisons that clarify or argue by similarity) - Illustrations (descriptive imagery or visuals) - Experiments / empirical results (scientific method outcomes) - Primary vs. secondary sources (original docs vs. analyses) On the exam you’ll need to identify these and explain how each supports the line of reasoning (logos) or builds credibility/emotional appeal (ethos/pathos). For practice and examples, check the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl) and thousands of practice questions at (https://library.fiveable.me/practice/ap-english-language).

Ask: does the evidence actually support the claim? Short checklist you can use every time: - Match evidence to the claim (warrant). Ask: how does this fact, statistic, anecdote, or expert testimony connect to the claim? If the link isn’t clear, the evidence is probably random. - Check type and credibility (CLE-1.C). Reliable facts, statistics, experiments, or named expert testimony support logos and ethos better than vague anecdotes or anonymous claims. - Look for relevance and sufficiency. One example may illustrate a point; multiple, varied pieces (facts + expert + statistic) build a stronger defense (CED expects you to select and explain evidence to support a line of reasoning on FRQs). - Watch for fallacies or gaps in reasoning. If the author leaps from X to Y without explaining why, the warrant is missing. - Consider rhetorical purpose and audience: evidence that appeals to pathos may persuade emotionally but not logically. Practice applying this checklist with the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl) and drill with 1,000+ practice questions (https://library.fiveable.me/practice/ap-english-language).

Anecdotal evidence is a short, specific story—often a personal experience or single example—used to support a claim. It’s a type of evidence listed in the CED (CLE-1.C) and appeals mostly to pathos and sometimes ethos: it makes an argument relatable but isn’t enough alone to prove something true for everyone. Example: If you claim “school start times should be later,” an anecdote would be, “My friend’s grades improved after the district moved start times back an hour.” That’s persuasive but limited—one case doesn’t show a general trend. On the AP exam, use anecdotes to illustrate or humanize a claim, then back them with stronger evidence (statistics, expert testimony, studies) and explain the warrant so your reasoning holds (CLE-1.B, 3.A). For a quick refresher, check the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl) and try practice questions (https://library.fiveable.me/practice/ap-english-language).

Look for four things: relevance, credibility, sufficiency, and how the writer connects it to the claim. - Relevance: Does the evidence directly support the specific claim or is it a tangent? Good evidence ties clearly to the claim (warrant). - Credibility: Who produced it? Check expert testimony vs. anecdote, primary vs. secondary source, currency, and possible bias (ethos). - Sufficiency & type: One anecdote = weak; multiple statistics, experiments, or corroborating examples = stronger. Quantitative data often supports logos; anecdotes strengthen pathos but need caution. - Explanation: The writer must explain how the evidence supports the claim (that’s required on the AP essays—“explain how the evidence supports the line of reasoning”). Watch for missing warrants or ignored rebuttals. For AP prep, review Topic 1.2 in Fiveable’s study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl) and practice with questions (https://library.fiveable.me/practice/ap-english-language).

Facts are specific, verifiable pieces of information (events, dates, definitions, eyewitness reports) used to support a claim. Statistics are a subset of facts that are numerical—percentages, averages, rates—used to quantify a claim (logos). Both can strengthen credibility (ethos), but they behave differently in an argument. Key differences you should watch for: - Precision: statistics give measurable support; facts can be concrete examples or claims about reality. - Need for context: stats need sample size, source, time frame, and method to be trustworthy; a standalone fact usually needs source verification (primary vs. secondary). - Risk of misuse: stats can be misleading (cherry-picked, nonrepresentative sample, bad math); facts can be anecdotal and not generalizable. - How you explain them on the exam: always connect the evidence to your warrant—explain how the fact or statistic supports your claim. In synthesis or argument prompts, cite at least three sources and explain relevance (see Topic 1.2 study guide) (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl). For more practice, try the AP practice problems (https://library.fiveable.me/practice/ap-english-language).

Start by naming the author’s claim in one clear sentence (thesis) and then pick 2–3 pieces of evidence the author uses (facts, statistics, anecdotes, expert testimony, analogy, etc.—CED CLE-1.C). For each piece, do three things: 1) identify the evidence type, 2) explain how it supports the claim (the warrant—connect evidence to the claim), and 3) note its rhetorical effect (ethos/pathos/logos or credibility/limitations). Example: “The statistic that X shows [evidence type: statistic], which bolsters the author’s logos because it quantifies the problem and justifies the proposed solution (warrant).” If evidence has limits, acknowledge a rebuttal or weakness—that sophistication can earn points on the FRQ. Remember AP rubric: have a defensible thesis, use specific evidence, and explicitly explain how evidence supports your line of reasoning (Rhetorical Analysis FRQ requirements). For more practice and examples, check the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl) and unit resources (https://library.fiveable.me/ap-english-language/unit-1), and drill questions at (https://library.fiveable.me/practice/ap-english-language).

When an AP question asks you to "identify and explain claims and evidence," do two things: 1) point out the claim(s)—the author’s thesis or smaller assertions that need defense (CLE-1.A), and 2) name the evidence supporting each claim and explain how that evidence actually backs it (CLE-1.B, CLE-1.C). Say what the evidence is (fact, statistic, anecdote, expert testimony, example, etc.), then show the warrant—the logical link that makes that evidence relevant to the claim. On the exam (MC and FRQs) you must do more than label: explain how the evidence strengthens the line of reasoning or where it falls short. For synthesis/argument essays, tie specific source evidence to your thesis and explain the connection (use at least three sources for the Synthesis task). For a quick refresher, see the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl) and practice questions (https://library.fiveable.me/practice/ap-english-language).

Expert opinions are usually signaled—look for named sources, titles, or credentials (Dr., professor, “researcher,” “study by…”). Writers quote experts with verbs like argues, concludes, or recommends; they may cite institutions or journals. Those are expert testimony/authority (ethos) you can call out. Regular examples are different: anecdotes, specific cases, or illustrative details that show rather than claim—personal stories, hypothetical scenarios, or ordinary examples. They’re concrete but don’t carry the same external credibility as expert testimony. On the AP exam, label evidence precisely (fact, statistic, anecdote, expert opinion) and explain the warrant—how that evidence supports the claim (CED CLE-1.B, CLE-1.C). Practice identifying these in passages and explain their rhetorical effect (ethos, logos, pathos) for free-response questions. For focused review, see the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl) and try practice items at (https://library.fiveable.me/practice/ap-english-language).

Personal observation = what you notice directly (patterns, sights, data you’ve seen). Personal experience = an event that happened to you (a story/anecdote). Both are CLE-1.C evidence types, but they play different roles: observations support logos by providing concrete, directly seen detail (e.g., “I watched three buses arrive late each morning”), while experiences appeal more to pathos and ethos because they’re narrative and show the speaker’s perspective (e.g., “When I missed work because the bus didn’t come…”). On the AP exam you can use either, but you must explain the warrant—how that observation or anecdote connects to your claim (CED requires explaining how evidence supports reasoning). Use observations when you need specific, generalizable detail; use experiences when you need to humanize or illustrate a claim. For more practice identifying and explaining evidence types, see the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl) and extra practice questions (https://library.fiveable.me/practice/ap-english-language).

An analogy as evidence works by comparing two things to show they’re alike in a relevant way, so the comparison supports the claim. For AP purposes, treat an analogy like any evidence: identify the claim it’s backing, state the implied warrant (why similarity matters), and evaluate strength. Good analogies have clear, relevant parallels (logos); weak ones rely on superficial similarities (false analogy). On FRQs, briefly paraphrase the analogy, explain the speaker’s reasoning (the warrant), and note limits or counterexamples to show critical thinking. Practice spotting strong vs. weak analogies in the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl).

Start with a clear thesis that restates the writer’s claim you’re analyzing. Then organize body paragraphs so each one focuses on a single piece or type of evidence (statistic, anecdote, expert testimony, example) from the passage. For each paragraph: (1) briefly identify the evidence and its type (CED CLE-1.C), (2) explain exactly how it supports the claim—show the warrant or reasoning that links evidence to the claim (CED CLE-1.B), and (3) note any appeals used (ethos, pathos, logos) and whether the evidence is credible. Include one paragraph that considers a potential counterargument or limitation and explain how the writer rebuts it or where the evidence falls short. End with a short conclusion tying the evidence back to the thesis and the overall rhetorical situation. This structure matches AP expectations: thesis, targeted evidence, and clear explanation of how evidence supports reasoning (see Topic 1.2 study guide on Fiveable: https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl).

“Defend their claims with evidence and reasoning” means more than dropping facts—it's showing how specific evidence actually supports your claim. In practice you should: state a clear claim/thesis; choose relevant evidence (facts, stats, examples, expert testimony, anecdotes—CLE-1.C); explain the warrant (how and why that evidence proves your point); evaluate credibility (ethos) and appeal logically (logos); and address likely counterclaims or limitations. On the AP exam this looks like using at least three sources in Synthesis or citing specific lines/techniques in Rhetorical Analysis, then explaining how each piece of evidence advances your line of reasoning (free-response scoring requires explanation of how evidence supports the argument). For quick review, see the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl).

Testimonies can be strong or weak depending on four things: credibility, relevance, specificity, and corroboration. Check the speaker’s credentials (expert vs. personal witness), expertise related to the claim (ethos), and potential bias or motive. Ask: is the testimony specific (dates, data, observations) or just vague opinion? Strong testimony explains how or why something is true and matches the claim’s scope; weak testimony is off-topic, anecdotal without context, or clearly biased. Look for independent support—statistics, studies, or other expert opinions that corroborate the testimony (logos). On the AP exam, you should identify and explain how a testimony supports a claim (CED skill 3.A) and integrate it with other evidence in a line of reasoning—don’t rely on a lone quote. For more examples and practice on evidence types, see the Topic 1.2 study guide (https://library.fiveable.me/ap-english-language/unit-1/how-evidence-supports-claim/study-guide/oLnF2sA5UTmiV6h57JXl) and try practice questions (https://library.fiveable.me/practice/ap-english-language).
