Support or refute a claim by selecting the most relevant and sufficient evidence. | Command of Evidence | SAT Reading and Writing

核心知识

Select evidence that is both directly relevant to the claim and detailed enough to actually support or refute it.

深入理解

This question type raises the bar: the evidence must be both relevant (connected to the right claim) and sufficient (strong enough to matter). A single anecdote might be relevant but not sufficient. A broad statistic might seem impressive but miss the specific claim.

The SAT builds distractors here by offering evidence that passes one test but fails the other. One choice might be perfectly relevant but too vague to actually support the argument. Another might contain hard data but address a slightly different question.

Train yourself to run a two-part check. First: "Is this about the right claim?" Second: "Is this specific enough to actually move someone's opinion?" The correct answer passes both tests.

分步讲解

Identify the claim and whether the question asks you to support or refute it.
Test each choice for relevance: does it address the specific claim, not just the general topic?
Test each choice for sufficiency: is it detailed and specific enough to actually affect the argument?
Eliminate choices that are relevant but vague, or specific but off-topic.
Choose the evidence that passes both the relevance and sufficiency checks.

常见误解

Picking evidence that mentions the right topic but doesn't address the specific argument being made.
Choosing broad or vague evidence (like "spending increased") when the claim requires specific supporting details.
Assuming that the longest or most detailed answer choice is automatically the best evidence.

示例解析

Historian James Chen argues that the expansion of public libraries in the late 19th-century United States was driven more by a desire for social control than by democratic ideals. Chen contends that wealthy benefactors who funded libraries sought to shape the reading habits and values of working-class immigrants rather than simply provide access to knowledge.

Which choice provides the most relevant and sufficient evidence to support Chen's claim?
