# SAT Command of Evidence (Textual): which finding would matter

Textual Command of Evidence gives you a claim and four findings or quotations. Why three of them are true and useless, three worked items to attempt, and the habit that separates relevant from supporting.

## The short answer

Command of Evidence: Textual gives you a claim, a hypothesis or an argument, then asks which of four findings or quotations would support it most directly. The passage runs 25 to 150 words. Three options are usually true, on topic and useless, because they bear on something other than the point in dispute. The skill is scored under Information and Ideas, about 26% of Reading and Writing.

## Key facts

- **Section:** Reading and Writing
- **Domain:** Information and Ideas
- **Domain share:** ~=26% of the section, 12-14 questions
- **Passage length:** 25-150 words
- **Options:** 4 (A-D)
- **If you are unsure:** Guess rather than leave it blank

Question counts, timings and domain shares come from College Board's test pages and the Digital SAT Suite Specifications Overview, checked 28 September 2026.

## How it's scored

Some items ask which finding would support a claim. Others ask which quotation illustrates one. Both turn on the same question: what exactly is being claimed?

Information and Ideas is about 26% of the section, 12 to 14 of the 50 operational questions. That count covers four skills, so there is no published number for this one alone.

> Mark the part of the claim that could be wrong. Evidence has to bear on that part. An option about anything else is decoration, however true it is.

## Command of Evidence: Textual examples

Worked examples written for this page. Answer each one before you open the model response: memorizing a response is scored as an irrelevant answer in the real test.

**Example 1 -- on topic, silent on the claim**

> Excavations at a Bronze Age settlement in Anatolia recovered obsidian tools whose chemistry matches a source 400 miles away. One archaeologist argues that the villagers obtained the obsidian through a chain of short local exchanges rather than by traveling to the source themselves.

Prompt: Which finding, if true, would most directly support the archaeologist's argument?

- A. Obsidian from that source appears at settlements all along the 400-mile route, in amounts that fall steadily with distance.
- B. The obsidian tools at the settlement were cut more skillfully than tools found near the source.
- C. The settlement traded grain with a village twelve miles away.
- D. One obsidian blade at the settlement weighed more than any blade found at the source.
Answer: A.

Model response: A. A steady falloff with distance is what a chain of short exchanges leaves behind. A single long journey would leave obsidian at the two ends and little in between.

Why it scores: B and D describe the tools themselves. They are on topic and say nothing about how the obsidian arrived, which is the only thing the argument is about.

**Example 2 -- evidence pointing the other way**

> In the 1840s Ignaz Semmelweis reported that washing hands in chlorinated lime cut deaths in a Vienna maternity ward. A historian claims that his colleagues turned the finding down less because of the numbers than because it implied that doctors themselves carried disease.

Prompt: Which finding, if true, would most directly support the historian's claim?

- A. Physicians who read the ward tables accepted the figures but objected to what Semmelweis said doctors should do.
- B. The ward records contained arithmetic errors that later editors had to correct.
- C. Chlorinated lime was costly and hard to obtain in Vienna hospitals.
- D. Semmelweis published his results in a book that few physicians read.
Answer: A.

Model response: A. Accepting the figures and objecting to the implication is exactly the split the historian describes: the numbers were not the problem.

Why it scores: B and D each explain the rejection a different way, so they work against the claim rather than for it. Direction matters here as much as topic does.

**Example 3 -- a result with nothing to compare it to**

> A city dropped minimum parking requirements from its downtown zoning code in 2016. An economist predicts that the change lowered the cost of building small apartment buildings, and that developers responded by putting up more of them.

Prompt: Which finding, if true, would most directly support the economist's prediction?

- A. Downtown rents rose by four percent in the three years after 2016.
- B. Permits for buildings under twenty units rose sharply downtown after 2016 and stayed flat in nearby districts that kept the requirement.
- C. The city council voted to drop the requirement by a wide margin.
- D. Most downtown residents said they supported the zoning change.
Answer: B.

Model response: B. The prediction is about small buildings going up, and permits count them. The districts that kept the rule are what rule out a citywide building boom.

Why it scores: C and D are about the decision and how people felt about it. The prediction is about what builders did next, and the nearby districts are what make B evidence instead of a coincidence.

## Common mistakes

| What costs marks | Do this instead |
| --- | --- |
| Choosing the option that is most on topic. | Topic is cheap. Ask whether the option changes how likely the claim is, and drop it if it does not. |
| Missing which direction the prompt wants. | Read the prompt twice. A support item and a weaken item can share three of their four options. |
| Accepting a result that has nothing to compare it to. | One figure rarely supports a claim about a cause. Look for the option that carries a baseline or a second group. |
| Restating the claim and calling it evidence. | Evidence is a separate fact. An option that repeats the claim in fresh words has proved nothing. |

## How to practice

1. Before you read the options, write the one sentence that would have to be true for the claim to hold.
2. For each wrong option, name what it would support instead. That makes the gap between relevant and supporting concrete.
3. Do ten items with the prompt covered, then check whether you were asked to support or to weaken. Note how often direction alone decided the item.
4. Keep a list of the claims you meet. Most are about a cause, a mechanism or a prediction, and each takes a different kind of evidence.

## Common questions

### What is the difference between the two Command of Evidence skills?

Textual items give you a text and ask which quotation or finding supports a claim. Quantitative items give you a table or a graph and ask which reading of the data supports it. The reasoning is the same; the source of the evidence is not.

### Do I need outside knowledge to answer these?

No. Every option is judged against the claim in front of you. A finding that is true in the world but silent on that claim is still the wrong answer.

### Are the findings in the options real?

They are written for the item, and the prompt usually marks them as hypothetical with the phrase "if true". You are not asked whether the finding happened, only whether it would matter.
