SAT Command of Evidence: Textual and Quantitative

Command of Evidence questions test your ability to match a claim to the exact detail proving it. You will see two versions on the digital SAT: one where you pick a supporting quote from a passage, and one where you read a table or graph and finish a sentence with the correct number.

Both versions belong to the Information and Ideas domain, along with Central Ideas and Details and Inferences. This domain checks your ability to locate, interpret, and use information from texts and from data displays.

Where Command of Evidence Fits

The digital SAT Reading and Writing section runs as two adaptive modules, each with 25 operational questions plus 2 unscored pretest questions, for 32 minutes per module and 64 minutes total across 54 questions. Every question is a discrete 4-option multiple-choice item tied to its own short passage or passage pair.

The table below shows how the section is built and where the Information and Ideas domain sits inside it.

The Information and Ideas domain supplies about 26 percent of scored (operational) Reading and Writing questions, 12 to 14 per full test, and this count covers all three skill points together: Central Ideas and Details, Command of Evidence, and Inferences. College Board does not publish a separate count for textual versus quantitative Command of Evidence questions, so treat any specific split you see elsewhere as an estimate, not an official number.

Textual Evidence Questions

A textual Command of Evidence question gives you a claim, usually about a researcher, historical figure, or fictional character, then asks which quote from the passage best supports the claim. The passage itself is short, often one paragraph, and the four answer options are all direct quotes pulled from it.

How to Read the Claim

The claim is the whole question. Read it slowly and note exactly what it asserts: is it about a cause, a result, a comparison, or an opinion someone holds? A quote might look interesting and still fail to prove the specific assertion.

Here is an original example of the pattern.

Passage: A city planner argued the redesign of Elm Street reduced average commute times more than any other change made in the year under review. Traffic engineers had reported the new bus lane cut average travel time by four minutes during peak hours, while a separate bike lane project showed no measurable change in car traffic speed. The planner also noted pedestrian complaints dropped after new crosswalk signals were installed, though she did not attribute this to commute times.

Question: Which quote from the text most directly supports the planner's claim: the Elm Street redesign reduced commute times more than any other change in the year under review?

• A. The bike lane project showed no measurable change in car traffic speed.
• B. Traffic engineers reported the new bus lane cut average travel time by four minutes during peak hours.
• C. Pedestrian complaints dropped after new crosswalk signals were installed.
• D. The planner did not attribute the drop in complaints to commute times.

Option B is correct because it gives a direct, measured drop in commute time tied to the redesign. Option A describes a different project with no effect, which rules it out rather than supporting the claim. Option C talks about complaints, not commute times. Option D is a true detail from the passage but restates what the claim is not about.

Distractor Patterns in Textual Items

Wrong options in textual Command of Evidence questions tend to fall into a few repeatable traps.

• A quote about a related topic never mentioning the specific outcome named in the claim.
• A quote supporting the opposite of the claim or a different part of the passage.
• A quote true on its own but answering a different question than the one asked.
• A quote too general to prove the specific, narrow wording of the claim.

Before you pick an answer, restate the claim in your own words and ask whether the quote proves this exact restatement, not something nearby.

Quantitative Evidence Questions

A quantitative Command of Evidence question pairs a short passage with a table, bar graph, or line graph, then asks you to complete a sentence with the data point matching the claim in the text. You are reading a display and matching it to language, not doing complex math.

Reading the Data Display First

Look at the axis labels, units, and any footnotes before you read the sentence you need to complete. Note what each row or column represents and confirm whether values are counts, percentages, or rates.

Here is an original example.

Passage: A study tracked the average number of hours per week residents in four neighborhoods spent using public parks. Researchers found neighborhoods with a park within a 10-minute walk had noticeably higher weekly usage than neighborhoods without one.

Question: Which choice completes the statement with data from the table supporting the researchers' claim most directly?

Among the four neighborhoods, the one with a park within a 10-minute walk recording the highest weekly usage was ______.

• A. Elmwood, at 5.2 hours per week.
• B. Birchfield, at 1.8 hours per week.
• C. Cedar Grove, at 4.9 hours per week.
• D. Oak Hollow, at 2.1 hours per week.

Option A is correct. Elmwood has a park within a 10-minute walk and posts 5.2 hours per week, the highest figure in the table, and this figure sits far above the 1.8 and 2.1 hours logged by the two neighborhoods without nearby parks. Pairing park access with the top usage number is exactly what the researchers' claim needs.

Option C reads the table correctly and Cedar Grove does have a nearby park, but 4.9 is not the highest weekly usage, so it makes the comparison weaker than it has to be. Options B and D report accurate numbers, yet Birchfield and Oak Hollow both lack a park within a 10-minute walk, so neither fits the blank or backs the link between park access and higher usage.

Distractor Patterns in Quantitative Items

Quantitative distractors usually target a specific reading mistake rather than a math error.

• A value from the wrong row or column, plausible-looking on a quick scan.
• The correct number attached to the wrong label or category.
• A true reading of the display supporting a different point than the claim in the passage.
• A value answering a nearby but different question, such as a total instead of an average.
• A number correct only if you misread a percentage as a raw count, or the reverse.

Trace each option back to one specific cell or bar in the display, then check the option against the claim as well. Do not rely on memory of the shape of the graph.

Textual vs Quantitative: Key Differences

The two types test the same underlying skill, matching evidence to a claim, but they draw on different reading habits.

A Shared Rule: Supporting vs Merely Related

The single biggest separator between the correct answer and the strongest wrong answer in both types is the difference between evidence supporting the claim and evidence merely related to the same topic.

Use this quick test on every option:

1. Restate the claim in one plain sentence.
2. Ask what specific fact would have to be true to prove this sentence.
3. Check whether the option states this exact fact, not a nearby fact about the same subject.
4. Eliminate any option accurate but proving a different point than the one asked about.

Related evidence often shares a topic, a person, or a data category with the claim, but it stops short of proving the specific relationship the claim describes. Correct evidence closes this gap directly.
