Compare positions without exaggerating disagreement · LSAT Reasoning

9 min + practice · Original foundation lesson

Two authors may share a premise while differing about its sufficiency or application.

Recognize the distinction

In paired passages, record each author's central position separately before comparing them. A second author may reject a first author's claim, limit it to certain cases, or accept it while adding another criterion. Treat those relationships as different. Do not turn a qualified extension into complete opposition simply because the passages are presented as a pair.

Choose a method

Build a shared-and-different map. State one proposition both authors could endorse and the exact issue on which their commitments diverge. For agreement questions, require support from both passages. For a relationship question, preserve whether the second author offers a counterexample, an additional condition, an application, or an alternative explanation of the same evidence.

Worked contrast

The museum pair agrees that chronological galleries can help. The second passage proposes thematic rooms alongside them, not abolition of chronology. The housing pair similarly keeps unit counts relevant but adds affordability and location. Both examples show a second author extending or qualifying an initial consideration without rejecting its relevance. The first author need not have explicitly opposed that extension.

Transfer and check

For transfer, imagine two reviewers who agree that a model predicts well but disagree on whether it should guide interventions. Identify the added requirement concerning causal relationships. Then write a misleading answer that exaggerates disagreement and explain which words make it unsupported. Precision about agreement is as important as precision about conflict.

WORKED EXAMPLE

Original foundation reading selection (shorter than a full official passage): Passage A: A museum should arrange objects by date so visitors can follow changes across time. Chronology supplies a shared framework and makes later departures from earlier practice visible. Passage B: Chronology is helpful, but grouping some objects by a common problem can reveal connections between distant periods. A thematic room need not replace the chronological galleries; it can invite visitors to reconsider them. Which statement best expresses the central point?

  1. Read the whole selection, including its qualifications.
  2. Passage B proposes thematic groupings as a complement to the chronology favored by Passage A.
  3. The detail 'Passage B says thematic rooms need not replace chronological galleries.' helps develop that central point but is narrower than it.
Answer: Passage B proposes thematic groupings as a complement to the chronology favored by Passage A.

Passage A explicitly rejects every thematic arrangement, while Passage B argues that visitors should encounter objects only in thematic rooms.

The two authors both insist that objects from different periods cannot be grouped together for any meaningful museum purpose.

Try it, then explain it.

Complete a short set without looking at the example. After each answer, explain which evidence or rule supports your decision and why the alternatives do not fit.
