How the SAT Tests It

Pattern

Support the Claim

A researcher or author makes a claim; pick the finding that backs it.

Clue: "most directly supports"
Pattern

Weaken the Claim

Pick the finding that undermines the stated hypothesis.

Clue: "most directly weakens"
Pattern

Illustrate the Statement

Pick the quotation from a literary work that illustrates a characterization.

Clue: "most effectively illustrates"

Worked Example

Claim: "The novelist portrays Elena as reluctant to abandon her hometown despite its decline." Which quotation best illustrates this?

We must illustrate TWO things at once: reluctance to leave AND awareness of decline.
This is an illustrate-the-statement question — the quote must show the claim, not just involve Elena or the town.
A quote showing Elena loves the town = only half. A quote showing the town is failing = only half. We need both in tension.
The right quote shows her hesitating to go while acknowledging what the town has lost — e.g., packing a suitcase she keeps unpacking as shops close around her.

Try It Yourself

Claim: "Octopuses use tools in ways that suggest planning for future needs." Which finding, if true, most directly supports this claim?

Common Traps

What students do

Matching the topic instead of the assertion.

Why it fails

Every option mentions the subject — that's what makes them tempting. Only one addresses the claim's specific logic.

Do this instead

Rewrite the claim as X does Y. The evidence must show Y happening, not just X existing.
