Textual evidence questions ask which finding would support or weaken a claim, or which quotation best illustrates it. First restate the claim in your own words and split it into its parts, such as a cause and an effect. Then predict what the evidence must show. The right answer matches every part of the claim. A choice that is on topic but proves nothing is wrong.

## What the question looks like

This skill is in the **Information and Ideas** domain. College Board says these questions ask you to use textual evidence, such as a fact, detail or example, to support, challenge or otherwise respond to a claim. There are two common forms:

- **Findings:** *Which finding, if true, would most strongly support the researchers' hypothesis?* (or *most directly weaken*)
- **Quotations:** *Which quotation from the poem most effectively illustrates the claim?* The claim is stated in the passage, often about a speaker or character.

## The rule: match every part of the claim

**Break the claim into parts before reading the choices**

| Claim | Its parts | Evidence must show |
| --- | --- | --- |
| Birds near roads sing higher *because* of traffic noise | Higher pitch + caused by noise | Pitch goes up when noise goes up, or birds sing lower where noise is low |
| The speaker feels hope *and then* regret | Hope + regret + in that order | A line that has both feelings, not just one |
| Trees in parks cool the air | Trees + lower temperature | Parks with trees are cooler than similar parks without trees |

*If true* means you accept the finding as a fact. Do not argue with whether it is realistic. Just ask: if this were true, would it make the claim more likely (support) or less likely (weaken)?

## Worked examples

**Example 1: which finding supports a hypothesis**

Problem: Biologists hypothesize that some songbirds living near busy roads sing at higher pitches than birds of the same species in quiet areas, because higher notes are easier to hear over the low rumble of traffic. Which finding, if true, would most strongly support the hypothesis? Choices: Birds near the roads sang at higher pitches during rush hour than late at night, when traffic was light. / Birds near the roads sang more songs per hour than birds in quiet areas. / Many bird species avoid nesting near busy roads. / Birds in quiet areas sang at a wide range of pitches.

1. Split the claim: (1) higher pitch, (2) caused by traffic noise.
2. Predict: pitch should rise when noise rises. The first choice shows exactly that, inside the same group of birds.
3. The second choice is about number of songs, not pitch. The third is about nesting. The fourth describes quiet-area birds with no comparison.

Answer: Birds near the roads sang at higher pitches during rush hour than late at night, when traffic was light.

**Example 2: which quotation illustrates a claim**

Problem: In an original poem, "Winter Orchard," the speaker suggests that the orchard, though it looks lifeless, is still alive. Which quotation most effectively illustrates the claim? Choices: "The branches hold no fruit, no leaf, / just snow along each crooked arm." / "Yet underneath the frozen ground / the roots are quietly kept warm." / "The farmer walks the rows at dawn / and counts the trees he planted young." / "The wind goes through the empty limbs / like songs that no one stays to hear."

1. Split the claim: (1) looks lifeless, (2) is still alive.
2. The first and fourth choices show only part 1: empty, snowy branches.
3. The second choice has *Yet* (turning from the lifeless look) and living roots kept warm. That shows both parts. The third choice shows neither.

Answer: "Yet underneath the frozen ground / the roots are quietly kept warm."

**Example 3: which finding weakens a claim**

Problem: A researcher claims that students remember more when they study in the same room where they will take the test. Which finding, if true, would most directly weaken the claim? Choices: Students who studied in a different room scored just as well as students who studied in the test room. / Students who studied longer scored higher. / Most students prefer to study at home. / Students who studied in the test room scored higher than those who studied elsewhere.

1. The claim compares two groups: same room versus different room.
2. To weaken it, the evidence must show no advantage for the same room. The first choice does that.
3. Study time and preferences do not compare rooms. The last choice supports the claim, the opposite of what is asked.

Answer: Students who studied in a different room scored just as well as students who studied in the test room.

## Common mistakes and fixes

| Mistake | Fix |
| --- | --- |
| Choosing a finding that is on the same topic but tests a different idea | Ask: does this choice say anything about the exact relationship in the claim? |
| Picking a quotation that shows only half the claim | List the claim's parts. The right quotation shows all of them. |
| Answering *support* when the question asks *weaken* | Circle the verb in the question before you read the choices. |
| Arguing with an *if true* finding | Accept it as fact. Your only job is to judge what it would mean for the claim. |
| Choosing a quotation because it has the same words as the claim | Look for the same idea, not the same vocabulary. Poems rarely repeat the claim's words. |

## Practice

**Five evidence questions**

1. Researchers hypothesize that city parks lower nearby summer air temperatures mainly because their trees provide shade and release water vapor from their leaves. Which finding, if true, would most strongly support the hypothesis?
   A. On summer afternoons, air was cooler in parks with many trees than in nearby treeless parks of the same size.
   B. Parks have more visitors in summer than in winter.
   C. Summer temperatures in the city have risen over the past fifty years.
   D. Some parks have large paved areas used for sports.

   Answer: On summer afternoons, air was cooler in parks with many trees than in nearby treeless parks of the same size.. The hypothesis says trees cause the cooling. Comparing parks of the same size that differ only in trees isolates the trees. Visitor numbers, citywide warming and paved areas say nothing about what trees do.

2. A nutrition writer claims that drinking a glass of warm milk before bed helps people fall asleep faster. Which finding, if true, would most directly weaken the claim?
   A. Milk contains calcium, which helps build strong bones.
   B. Milk is more popular in some countries than in others.
   C. People who drank milk before bed said they enjoyed the taste.
   D. In a study, people who drank warm milk before bed took about as long to fall asleep as people who drank warm water.

   Answer: In a study, people who drank warm milk before bed took about as long to fall asleep as people who drank warm water.. The claim is about falling asleep faster. A fair comparison showing no difference in time to fall asleep directly weakens it. Bones, taste and popularity do not touch the claim.

3. In an original poem, the speaker expresses regret about leaving home. Which quotation from the poem most effectively illustrates the claim?
   A. "The road ahead was wide and bright, / and I walked out without a sound."
   B. "My mother's garden grew tall corn / and beans that climbed the wooden fence."
   C. "Now every city light I pass / reminds me of the porch I left, / and I wish I'd stayed to say goodbye."
   D. "The train ran east across the plains / through towns I'd never seen before."

   Answer: "Now every city light I pass / reminds me of the porch I left, / and I wish I'd stayed to say goodbye.". The claim has two parts: leaving home and regret. Only this choice shows both, through *the porch I left* and *I wish I'd stayed*. The others show leaving, a memory, or travel, but no regret.

4. In an original short story, the narrator describes Leo as careful to the point of worry. Which quotation from the story most effectively illustrates this claim?
   A. "Leo checked the stove three times before he left, then turned back at the corner to check it again."
   B. "Leo's sister called him every Sunday at noon."
   C. "Leo liked his coffee black and his music loud."
   D. "Leo had lived in the same apartment for nine years."

   Answer: "Leo checked the stove three times before he left, then turned back at the corner to check it again.". Checking three times and then going back again shows care that has become worry. The other quotations describe his tastes, his sister's habit, and how long he has lived somewhere, none of which shows worry.

5. Some scientists claim that the bright colors of poison dart frogs warn predators that the frogs are toxic. Which finding, if true, would most strongly support the claim?
   A. Poison dart frogs live in tropical rainforests.
   B. In experiments, birds that once tasted a toxic, brightly colored frog avoided frogs with the same coloring afterward.
   C. Many poison dart frogs lay their eggs on land rather than in water.
   D. The frogs' toxins come from insects they eat in the wild.

   Answer: In experiments, birds that once tasted a toxic, brightly colored frog avoided frogs with the same coloring afterward.. A warning works only if predators learn to link the colors with a bad experience and then stay away. This finding shows that. Habitat, egg laying and the source of the toxins do not show that colors change predator behavior.

## Frequently asked questions

### What does "if true" mean in these questions?

It means treat the finding as a fact for this question. The test is not asking whether the finding is likely or realistic. It is asking what the finding would mean for the claim if it were true: would it make the claim more believable, less believable, or not matter?

### How do I read a poem quickly enough for quotation questions?

Read the claim first, then read only the quoted lines in the choices. You often do not need the whole poem. Hold each quotation up against the claim's parts. See [poetry and literature passages](https://duckyhelper.com/learn/sat-reading-writing/poetry-and-literature-passages/) for how to read the language itself.

### What is the difference between textual and quantitative evidence questions?

Textual questions use findings, details or quotations written in words. Quantitative questions give you a table or graph and ask which data supports a claim. The thinking is the same: match every part of the claim. See [command of evidence: quantitative](https://duckyhelper.com/learn/sat-reading-writing/command-of-evidence-quantitative/).
