Comparison

Master the art of analyzing two paired passages on the LSAT: identify agreements, disagreements, and the logical relationships between authors.

LSAT Reading Comprehension

What Is Passage Comparison?

On the LSAT Reading Comprehension section, one of the four passage sets consists of two shorter passages (Passage A and Passage B) instead of one long passage. These paired passages address the same topic but from different angles, and several questions will ask you to compare them.

Why Passage Comparison Matters

Guaranteed on Every Test

Every LSAT RC section includes exactly one comparative reading set: typically 5-8 questions worth of points.

Higher-Order Thinking

These questions reward synthesis and relational reasoning, not just recall: skills that distinguish top scorers.

Unique Question Types

Comparison questions use formats you won't see with single passages, like "Both authors would agree" or "Unlike Passage A, Passage B..."

Anatomy of a Comparative Set

Five Relationship Types

1

Agreement: Both authors reach the same conclusion or endorse the same principle.

2

Disagreement: The authors reach opposing conclusions on the same issue.

3

Qualification: One author refines, limits, or adds nuance to the other's claim.

4

Complementary: Each discusses a different aspect of the same topic; no direct conflict.

5

Application: One passage provides theory, the other provides a concrete case or critique.

Agreement vs. Shared Topic

One of the most common traps on the LSAT is confusing agreement on a conclusion with merely discussing the same subject. Two passages can talk about the same phenomenon and arrive at completely different conclusions.

	Agreement	Shared Topic Only
Same subject?	Yes	Yes
Same conclusion?	Yes	No
Same evidence?	Often different	Often different
LSAT trap?	Overstating agreement	Assuming agreement exists

Recognizing Comparison Questions

Comparison questions use distinctive language. Learn to spot these stem patterns so you can activate your comparison framework immediately.

Both / Each

"Both passages discuss..." or "Each author would agree that..."

Unlike / Differs

"Unlike the author of Passage A..." or "The passages differ in..."

Respond / React

"Author B would most likely respond to Author A by..." or "How would Author A characterize..."

How to Attack Comparative Passages

1

Read Passage A fully. Identify its main conclusion, key evidence, and tone. Jot a one-line summary.

2

Read Passage B with A in mind. Actively compare as you read: where does B agree, disagree, or shift focus?

3

Map the relationship. Before looking at any questions, articulate the core relationship in your own words.

4

Answer single-passage questions first. These build your understanding before tackling harder comparison questions.

5

For comparison questions, return to both passages. Verify your answer has support in both texts, not just one.

Example 1: Mapping the Relationship

Example 2: "Both Would Agree" Questions

Even when authors disagree on a central issue, they may share background assumptions. A "Both would agree" question asks you to find common ground beneath the disagreement.

Example 3: "How Would B Respond?"

These questions ask you to adopt one author's perspective and evaluate the other's argument from that viewpoint. You must stay in character and select the response most consistent with the author's stated views.

1

Identify the specific claim from Passage A that the question references.

2

Review Passage B's principles and conclusions. What does Author B believe?

3

Ask: would Author B agree, disagree, or qualify that specific claim? Find the answer that matches B's likely response.

Example 4: Structural Comparison

Some questions compare not what the authors say, but how they argue. These structural comparison questions ask about method, organization, or rhetorical strategy.

Signal Words in Passage Comparison

Authors often telegraph their relationship to other viewpoints through signal language. Train yourself to flag these words as you read Passage B.

Agreement Signals

similarly, likewise, consistent with, as [other scholars] note, confirms, corroborates

Disagreement Signals

however, on the contrary, critics argue, this view fails to, unlike, challenges

Qualification Signals

while partially correct, though this overlooks, to a limited extent, nuanced by, more precisely

Common Mistakes to Avoid

✕ Conflating Topic with Agreement

Both passages discuss the same subject, so you assume the authors agree. Shared topic does not equal shared conclusion.

✕ Answering from One Passage Only

You find strong support in Passage A but forget to verify that the answer also holds for Passage B. Both must support the answer.

✕ Importing Outside Knowledge

You know the topic well and answer based on your opinion rather than what the specific authors actually state or imply.

Question Type Summary

Question Type	What It Asks	Key Strategy
Both Would Agree	Find shared ground	Look for background assumptions, not main claims
Primary Disagreement	The core point of conflict	Identify where conclusions directly oppose
Author's Response	How one would react to the other	Stay in character: use only that author's stated views
Structural Comparison	How the arguments are built	Compare methods, organization, and rhetorical moves
Shared Purpose	What both passages aim to do	Abstract beyond content to the passages' goals

Question 1 of 5

Passage A: The expansion of standardized testing in public education has been instrumental in maintaining accountability and identifying achievement gaps across districts. Without objective metrics, school administrators would lack the data needed to allocate resources effectively and ensure educational equity.

Passage B: While accountability measures are important, the overreliance on standardized testing has narrowed curricula, increased student stress, and incentivized teaching to the test rather than fostering genuine learning. Alternative assessment models, such as portfolio-based evaluations, offer more holistic measures of student growth.

▼ Tap to read passage

The authors of the two passages would be most likely to agree on which of the following?

Both authors accept the importance of accountability: Author A explicitly values it, and Author B acknowledges it with "accountability measures are important." The other options reflect only one author's position or are too extreme.

Question 2 of 5

Passage A: Artificial intelligence will transform the legal profession by automating routine tasks such as document review, contract analysis, and legal research. This will free lawyers to focus on higher-order strategic thinking and client counseling, ultimately improving access to justice.

Passage B: The integration of AI into legal practice raises serious concerns about professional responsibility. Algorithms trained on historical data may perpetuate existing biases, and clients may be harmed when complex legal judgments are delegated to machines incapable of ethical reasoning.

▼ Tap to read passage

The relationship between the two passages is best described as:

Passage A is enthusiastic about AI in law ("will transform," "improving access"), while Passage B raises "serious concerns" about the same development. This is a classic optimism-vs-caution disagreement on the same topic.

Question 3 of 5

Passage A: Urban green spaces serve primarily as recreational amenities, providing residents with areas for exercise, socializing, and mental relaxation. Cities that invest in parks see measurable improvements in public health outcomes and property values.

Passage B: The ecological functions of urban green spaces are underappreciated. These areas act as carbon sinks, mitigate urban heat islands, manage stormwater runoff, and support biodiversity. Planning decisions should prioritize these environmental services over purely aesthetic or recreational considerations.

▼ Tap to read passage

The author of Passage B would most likely respond to Passage A's characterization of green spaces by arguing that it:

Author B explicitly states ecological functions are "underappreciated" and that planning should "prioritize environmental services over purely aesthetic or recreational considerations." B would see A's recreational framing as exactly the kind of undervaluation B is critiquing.

Question 4 of 5

When answering a "Both authors would agree" question on the LSAT, the correct answer is most often:

The correct answer to "both would agree" questions is almost never a main conclusion (which is where authors typically differ). Instead, it's a more modest proposition: a shared background assumption, a fact both accept, or a principle neither would dispute.

Question 5 of 5

Passage A: Cognitive behavioral therapy (CBT) is the gold standard for treating anxiety disorders, supported by decades of randomized controlled trials. Its structured, evidence-based approach allows therapists to measure progress objectively and adjust treatment protocols accordingly.

Passage B: While CBT's empirical support is well established, its emphasis on symptom reduction may overlook the deeper relational and existential dimensions of human suffering. Psychodynamic approaches, though harder to measure, often address the root causes of distress that CBT's focus on cognition and behavior may leave untouched.

▼ Tap to read passage

Which of the following best describes the relationship between the two passages?

Passage B does not deny CBT's empirical support ("well established") but argues CBT is incomplete: it "may overlook" deeper dimensions. This is a qualification, not a contradiction. B accepts A's claim but argues it doesn't go far enough.
