SAT Reading — Textual Evidence and Data Support Questions

What These Questions Ask

Evidence support questions give you a claim and ask you to find which quote or piece of data from the passage best supports (or sometimes undermines) that claim.

Two formats: 1. Paired questions: A reading question followed by "Which quotation from the text best supports your answer?" 2. Data questions: A graph or table is shown alongside a passage; you choose which answer uses the data correctly.

The Key Move: Match Claim to Evidence

The wrong answers in evidence questions often:

  • Mention the right topic but don't actually support the specific claim
  • Are true statements from the passage but support a different point
  • Partially relate to the claim but leave out the key part
  • The correct evidence must directly prove the specific claim you're supporting — not just be from the same neighborhood.

    Strategy: Work Backward from the Claim

    For paired questions: 1. Write the claim in your own words 2. Go through each quote option and ask: "Does this directly prove my claim?" 3. Eliminate any quote that doesn't include the key element of the claim

    For data questions: 1. Read the graph/table carefully (title, axes, units) 2. Identify what the question asks you to prove 3. Look for the answer that accurately reads the data AND supports the claim — don't pick answers that distort the data or make up a trend that isn't there

    Common Data Interpretation Mistakes

  • Confusing correlation and causation: A graph showing two things rising together doesn't prove one causes the other
  • Ignoring scale: A big-looking bar might represent a small number if the y-axis starts at 90
  • Overreading trends: The correct answer will be what the data actually shows, not what you'd expect it to show
  • Real-world example: A passage argues that teens who sleep more perform better academically. A graph shows average GPA vs. average hours of sleep for 500 students. A question asks which conclusion is supported by the data. The correct answer would be something like "Students who sleep 9+ hours have higher average GPAs than those who sleep fewer than 7 hours." A wrong answer might say "Sleep is the most important factor in academic success" — the graph shows a correlation, not that sleep is more important than all other factors.

    Key Terms

  • Textual evidence: A quote or excerpt from the passage that directly supports a claim
  • Paired question: A two-part question format where you first answer a reading question, then find the supporting quote
  • Data support question: A question using a graph or table alongside text; requires accurate data reading
  • Supports vs. undermines: Some questions ask for evidence AGAINST a claim — make sure you're answering the right question
  • Correlation: Two things that change together; does NOT prove causation
  • Accurately describes: The key test for a data answer — does this answer correctly reflect the numbers?

Quiz Questions:

Q1. A student claims that the passage argues urban trees reduce air pollution. Which quote from a hypothetical passage would best support this claim?

A) "Urban trees provide shade, which reduces energy costs for nearby buildings." B) "Studies have shown that street trees in cities absorb significant amounts of carbon dioxide and particulate matter." C) "Trees are important for biodiversity and provide habitat for birds and insects." D) "City planners have long recognized the aesthetic value of urban greenery."

Answer: B — Only choice B directly supports the claim that trees reduce air pollution. Choice A is about energy savings. Choices C and D mention trees but not air pollution specifically.

Q2. A graph shows that countries with higher literacy rates have lower infant mortality rates. A student concludes: "Higher literacy rates cause lower infant mortality." Is this conclusion supported by the data?

A) Yes, the graph proves causation B) No, the graph shows a correlation but does not establish that literacy causes lower mortality C) Yes, any data that shows two trends moving together proves causation D) No, the graph shows the opposite — lower literacy correlates with lower mortality

Answer: B — A graph showing two variables moving in the same direction demonstrates correlation, not causation. The graph does not rule out other explanations (e.g., both literacy and health outcomes improve due to higher overall development). This is the most important data reasoning rule on the SAT.

Q3. A passage states: "The author suggests that space exploration has more cultural than scientific value." A student answers a paired question: "Which quote best supports this?" They choose: "The Moon landing inspired generations of engineers and scientists." Does this quote support the claim?

A) Yes, it directly shows that space exploration has more cultural value than scientific value B) No, it shows that space exploration inspired scientists, which is closer to scientific than purely cultural value — and it doesn't establish that cultural value exceeds scientific value C) Yes, inspiration is a cultural benefit D) No, quotes cannot support claims about value judgments

Answer: B — The quote shows inspiration (which is a benefit), but it doesn't directly prove that cultural value exceeds scientific value. The claim makes a comparison ("more cultural than scientific"), which requires evidence that explicitly weighs both sides. This quote doesn't do that.

Q4. A student reads a chart showing sales of electric vehicles (EVs) from 2015 to 2023. EV sales grew each year. The question asks: "Which conclusion does the data most directly support?" The answer choices include:

A) "EVs will eventually replace gasoline vehicles entirely." B) "EV sales increased consistently from 2015 to 2023." C) "The increase in EV sales was caused by government incentives." D) "EVs are now more popular than gasoline vehicles."

The best answer is:

A) A B) B C) C D) D

Answer: B — Choice B accurately describes what the chart shows: consistent growth in EV sales from 2015–2023. Choice A predicts a future outcome the data can't prove. Choice C assumes a cause the chart doesn't identify. Choice D would require comparative data on gasoline vehicle sales that isn't shown.

Q5. For a paired question, the first question asks: "What does the passage suggest about the author's view of social media?" The student answers: "The author is critical of social media's effect on teenagers." To support this answer, the best quote would be:

A) "Social media platforms were first developed in the early 2000s." B) "Many teenagers report spending over 4 hours per day on social media." C) "Research has linked heavy social media use among teens to increased rates of anxiety and depression." D) "Social media companies have introduced parental control features."

Answer: C — This quote directly supports a critical view — it provides evidence of negative effects. Choice A is a historical fact with no evaluative content. Choice B describes a behavior without judging it. Choice D describes a company response, not a critique.
