BY THE END, YOU CAN
Translate a claim into the observation it predicts.
Distinguish relevant support from merely related facts.
Evaluate quotations, findings, counterevidence, and alternative explanations without overclaiming.
BEFORE YOU START
A claim is what is argued; evidence is the fact, observation, or example offered for it.
Evidence can make a claim more plausible without proving it beyond doubt.

LEARN THROUGH ORIGINAL PRACTICE
Original SAT-style worked examples and practice
The teaching passages, worked examples and exercises in this lesson are original. They are not official College Board questions or past-exam reproductions. Blueprint and observed-practice analytics describe separate factual metadata; those source questions are not displayed here.
01 / UNDERSTAND & APPLY
Start with the exact claim
Textual evidence tasks ask which fact, detail, example, or quotation would best support a specified point. Some prompts ask what would weaken a proposed explanation. Underline the claim’s subject, relationship, and qualifiers before considering choices. “Can help under dry conditions” predicts much less than “always helps.”
Write a short evidence target: “I need an observation connecting X with Y under condition Z.” A fact can mention X and still be irrelevant if it says nothing about Y. All findings, quotations, people, and studies in this lesson are fictional teaching scenarios.
02 / UNDERSTAND & APPLY
Build a claim-to-evidence bridge
Explain the bridge aloud: “If this observation is true, the claim becomes more plausible because…” If you cannot complete that sentence without adding facts, the support is weak. Direct evidence addresses the disputed relationship; background only makes the topic understandable.
For a literary claim, ask which language demonstrates the interpretation. A claim about a character’s reluctance needs hesitation, delay, or resistance in the passage, not simply a description of the room.
ORIGINAL WORKED EXAMPLE
A relevant observation
Fictional claim: Extending the archive’s opening hours helped workers whose shifts ended after the archive’s former closing time visit. Which finding best supports it? A The archive repainted its walls. B Many new visitors worked until 6 p.m. and attended after the former closing time. C The archive owns old maps. D Nearby shops sell postcards.
Target the group and the mechanism: workers could not attend before, but can attend during the added hours.
B directly links new visitors to that access change.
A, C, and D may describe the setting but do not connect the hours to these workers’ visits. B supports the explanation; it does not prove hours were the only influence.
Answer B. Visits by workers whose shifts ended after the archive’s former closing time during the added hours.
03 / UNDERSTAND & APPLY
Support every essential part
A comparative claim requires a comparison. A change claim requires information about at least two conditions or times. A claim about an unusual feature requires a relevant baseline. Do not accept evidence that establishes only one half of a two-part assertion.
A single example can establish that something is possible; it normally cannot establish that something always happens. Likewise, one exception can defeat a strict “all” claim but may not meaningfully refute a claim about a general tendency.
ORIGINAL WORKED EXAMPLE
Comparative evidence
Fictional claim: In this workshop, written assembly guides produced fewer errors than spoken instructions alone. Best support? A The guides had blue covers. B Some assemblers preferred silence. C Comparable groups averaged two errors with guides and five with spoken instructions alone. D The workshop opened in spring.
The target is an error-rate comparison between instruction conditions.
C supplies both conditions and the direction claimed; comparable groups improve relevance.
A concerns appearance, B preference rather than errors, and D timing rather than instruction. The evidence remains limited to the described workshop.
Answer C. The paired error results directly address the comparison.
04 / UNDERSTAND & APPLY
Choose language that demonstrates the interpretation
In fiction and poetry, distinguish what a line depicts from what it lets you infer. Repeated checking may support uncertainty; a confident declaration may support resolve. A vivid quotation is not automatically the best evidence. Its meaning must connect to the exact interpretation.
Keep the character, narrator, and author distinct. A character’s statement may reveal the character’s belief without establishing the story’s factual truth.
ORIGINAL WORKED EXAMPLE
A quotation for hesitation
Fictional claim: Daro wants to leave but remains uncertain. Which original line best supports it? A “The street had three lamps.” B “He lifted his bag, set it down, and checked the silent doorway once more.” C “The ticket cost four coins.” D “He left without looking back.”
The claim combines an impulse to depart with unresolved hesitation.
B contains both the lifted bag and the reversal/checking.
A and C are setting details. D indicates decisive departure and so does not support the uncertainty in the claim.
Answer B. The sequence of actions reveals hesitation.
05 / UNDERSTAND & APPLY
Evaluate findings, controls, and alternatives
When a passage proposes an explanation, identify what outcome the explanation predicts and what rival explanation could produce the same outcome. Evidence is stronger when it distinguishes among those possibilities. A comparison that holds relevant conditions steady is often more informative than a raw before-and-after change.
Do not silently turn correlation into causation. Evidence that two events occur together can support a hypothesis, but a third factor may influence both. A well-chosen finding can weaken a causal story without proving the opposite story.
ORIGINAL WORKED EXAMPLE
Weakening a proposed cause
Fictional proposal: A new wall coating caused a storage room to become cooler. Which finding most weakens that explanation? A The coating came in three colors. B The building’s cooling system was replaced at the same time, and uncoated rooms cooled by the same amount. C Staff liked the coating. D The room contained shelves.
The claim assigns the cooling to the coating. Look for evidence that the outcome occurred without that coating.
B supplies a concurrent alternative and the same result in uncoated rooms.
A, C, and D do not test the cause. B weakens attribution to the coating; it does not establish that coating can never affect temperature.
Answer B. Comparable cooling without the coating undermines the proposed explanation.
06 / UNDERSTAND & APPLY
Check relevance before dramatic size
The “best” evidence need not be the largest number or strongest wording. A modest observation of the right relationship may be more useful than a dramatic statistic about something else. Check direction: does the evidence support the claim, challenge it, or leave it untouched?
If the prompt asks which finding would support a hypothesis, treat each offered finding as true for the exercise. You are testing its logical bearing, not claiming it happened in the real world.
ORIGINAL WORKED EXAMPLE
An exception has a precise target
Fictional claim: Every vessel made with the new clay cracks when dried outdoors. Which observation most directly challenges it? A One new-clay vessel dried outdoors without cracking. B Ten old-clay vessels cracked indoors. C New clay costs more. D Most vessels are painted.
“Every” allows no exceptions; one matching case with the opposite outcome is enough to challenge it.
A meets the material and drying condition but lacks the predicted crack.
B changes both material and condition; C and D concern unrelated properties. A would not disprove the weaker claim that many such vessels crack.
Answer A. One genuine counterexample defeats the universal claim.

Original practice: select relevant support
For each choice, write a one-sentence bridge from the evidence to the claim.
ORIGINAL PRACTICE · 1
Fictional claim: The character feels excluded at dinner. Best evidence? A “The soup was warm.” B “Each time she began a story, the others turned to a different speaker.” C “There were six chairs.” D “The window faced west.”
Reveal answer & reasoning
B
Repeatedly being ignored directly supports exclusion. A and D describe surroundings; C gives a count without showing exclusion.
ORIGINAL PRACTICE · 2
Fictional claim: A tool works on both wet and dry surfaces. Best support? A It costs little. B It was tested only on dry wood. C It held securely in separate wet-surface and dry-surface trials. D Its maker likes rain.
Reveal answer & reasoning
C
Both required conditions appear in C. B supports only half the claim; A and D do not establish performance.
ORIGINAL PRACTICE · 3
Fictional claim: Shorter labels reduced reading time compared with the old labels. Best support? A The new labels were printed on Friday. B The old labels used black ink. C Every label had a title. D Matched visitors took less time to read the new labels than the old ones.
Reveal answer & reasoning
D
D measures the claimed outcome under both formats. A, B, and C do not compare reading time.
ORIGINAL PRACTICE · 4
Fictional claim: The narrator gradually becomes more trusting. Best support? A Early she hides her plans; later she asks a neighbor to keep her spare key. B She wears the same coat throughout. C The story takes place in winter. D Her neighbor owns a key.
Reveal answer & reasoning
A
A supplies a before-and-after behavioral contrast consistent with increased trust. B and C are unrelated continuity/setting. D alone says nothing about the narrator’s change.
08 / UNDERSTAND & APPLY
Original practice: challenge and calibrate
A result that fails to support a claim does not necessarily disprove it. Identify exactly how much each finding changes the argument.
ORIGINAL PRACTICE · 1
Fictional hypothesis: Music alone caused seedlings in Room A to grow faster than those in Room B. Most useful challenge? A Both rooms had pots. B Room A also received twice as much light. C The music was instrumental. D The pots were numbered.
Reveal answer & reasoning
B
Unequal light is a plausible competing growth condition, weakening attribution to music alone. A and D are neutral; C identifies music type without testing its effect.
ORIGINAL PRACTICE · 2
Fictional claim: All three translators omitted the final stanza. Most direct challenge? A One translator preserved the final stanza. B All used paper. C One translation was long. D Readers liked the poem.
Reveal answer & reasoning
A
One included final stanza contradicts “all three omitted.” B and D are irrelevant; C does not identify which content made it long.
ORIGINAL PRACTICE · 3
Fictional claim: A proposed reading circle may help isolated residents meet neighbors. Best support? A The chairs are red. B The circle has a long name. C Previously unacquainted residents began visiting one another after meeting there. D Some residents read quickly.
Reveal answer & reasoning
C
C gives a social connection plausibly linked to the circle, supporting the limited “may help” claim. A, B, and D do not concern neighbor relationships; C does not show the circle is the only possible cause.
ORIGINAL PRACTICE · 4
Fictional claim: A courier chose a route because it was quieter, not because it was shorter. Best evidence? A The courier owned a bicycle. B The route had trees. C The trip occurred on Tuesday. D The courier rejected a shorter noisy road and described quiet as the deciding factor.
Reveal answer & reasoning
D
D directly distinguishes the competing motives using choice and stated reason. A and C do not address motive; B does not establish either noise or the deciding reason.
KEEP THE BIG IDEAS
Quick revision
Specify the claim before looking for evidence.
A relevant fact must connect to the disputed relationship.
Comparisons need comparison evidence; universal claims can be challenged by one genuine exception.
Support and weakening have degrees; neither automatically proves an opposite claim.
