RC Comparative Passages.
The trap is answering from only one passage.
Why the top miss on Comparative is a choice that is true in Passage A but wrong about Passage B. The two-skeleton method. Seven sub-patterns.
Also known as: Dual passages, Paired passages.
RC Comparative Passages pairs two short passages on a related topic and asks questions that require understanding the relationship between the two authors. The defining trap is an answer that accurately describes one passage but ignores or misrepresents the other. Build a one-sentence skeleton for each passage before reading the choices. The credited answer on a relationship question must hold for both passages simultaneously. Seven sub-patterns cover the range of question types: relationship, inference across both, function of element in both, comparative main point, author attitude across both, primary purpose across both, and analogy/application to both.
The pattern
RC Comparative Passages pairs two short passages (Passage A and Passage B) on a related topic. Questions test the relationship between the two authors: where they agree, where they disagree, what one would say about the other, and how each uses specific evidence. The defining trap is a choice that accurately describes one passage but misrepresents or ignores the other. Read both passages first. Build a one-sentence skeleton for each. Then ask: what does each author claim, and how do those claims relate?
The stem usually reads as one of these:
- Which of the following best describes the relationship between Passage A and Passage B?
- The authors of Passage A and Passage B would most likely agree on which of the following?
- Which of the following would the author of Passage B be most likely to say in response to Passage A?
- Which of the following is supported by both passages?
- How does the author of Passage B respond to the type of argument made in Passage A?
Sub-patterns
The question asks how the two passages relate overall: agreement, disagreement, one extends the other, one rebuts the other, or one provides evidence the other interprets differently.
The right answer combines commitments from both passages. Neither passage alone supports the answer. The trap is an answer supported by one passage but contradicted or unaddressed by the other.
A specific piece of evidence or claim appears in both passages. The question asks what function it serves in each. A piece of evidence can serve opposite functions in two passages that take opposing positions.
The question asks for the main point of each passage, or asks which choice captures what both passages are about. Both skeletons must match the credited answer.
The question asks about one author's attitude toward the subject, toward a specific claim, or toward the other passage. Attitude is signaled by word choice, by what the author endorses or qualifies, not by what the author merely describes.
The question asks the primary purpose of each passage or asks which choice describes both authors' purpose. Purpose answers describe what the author is doing (arguing, analyzing, rebutting, illustrating) rather than what the passage is about.
The question presents a scenario and asks which passage author would view it more favorably, or how the scenario applies to the arguments of both. Map the scenario against each skeleton before evaluating choices.
Three trap patterns.
The first slip
The top miss on RC Comparative Passages is the one-passage-only answer. A choice is accurate for Passage A, the student confirms it, and moves on without checking Passage B. On every Comparative question, both passages must be accounted for in the credited answer. One passage correct and one passage wrong is still a wrong answer.
The compounding slip
The second most common miss is over-reading the relationship. Students see that the two passages disagree and conclude the relationship must be adversarial or one-sided. Most Comparative passages have a nuanced relationship: they might disagree on one point and share an implicit assumption on another. The question tests which specific relationship the choices describe.
Why it sticks
A Comparative answer that covers only one passage is a distractor. Every credited answer on a relationship question must hold for both.

Passage A
I bought Pinaka Books on Pennsylvania Avenue five years ago because I believed the two dominant models for running an independent bookstore were both wrong. The full-retail model treats every section the same and assumes price is irrelevant to a customer who already walked in. The member-discount model assumes loyalty is the scarcest resource and discounts indiscriminately to protect it. Neither model asks what actually drives purchase behavior inside a specific section.
My operating thesis is narrower. Pricing outcomes at an independent bookstore depend on the context of each section, not on a single store-wide philosophy. Legal-reference customers treat price as a secondary factor because the purchase is tied to professional necessity. Fiction customers are more sensitive to price because the purchase is discretionary. History customers occupy a middle position.
Last quarter I tested three strategies simultaneously: full-retail on fiction, a 10 percent subscriber discount on history, and dynamic weekly pricing on legal reference. The data confirmed the thesis. Fiction sales were flat under full-retail. History saw a lift from the subscriber discount, but the lift came entirely from existing subscribers, not new ones. Legal-reference performance was stable under dynamic pricing because those customers were not responding to price at all.
The investor case is simple. A store that prices by section can optimize each section independently. A store locked into one philosophy applies the wrong tool to two out of three sections by design. The approach requires more operational attention. The returns justify it.
Passage B
Dynamic pricing and section-specific discounting have gained attention among independent bookstore operators in recent years. The appeal is intuitive: different customers have different price sensitivities, and treating all sections identically leaves revenue on the table. The appeal does not survive contact with two operational realities.
First, customers at independent storefronts develop expectations through repetition. A legal-reference customer who finds a title priced at eighty dollars one week and ninety-two dollars three weeks later does not conclude that prices fluctuate. She concludes that the store cannot be trusted. Research on price variability in independent retail consistently shows that trust erosion from dynamic pricing exceeds the short-term margin gain in stores below roughly two hundred transactions per day. Most independent bookstores do not approach that volume.
Second, section-specific pricing strategies require staff to hold multiple pricing rules simultaneously. A staff member ringing up a customer who has books from two sections must know which discount applies, whether the dynamic price has been updated this week, and how to explain the difference if the customer asks. Training costs rise. Error rates rise. Customer complaints about pricing inconsistency are, in this industry, among the top five drivers of one-star reviews.
The enthusiasm for fine-grained pricing models among independent operators is understandable. The evidence that those models improve outcomes at sub-two-hundred-transaction venues is not there. Independent storefronts that have adopted section-specific approaches report higher operational overhead and mixed revenue results. The simpler pricing model is simpler for a reason.
Which of the following best describes the relationship between Passage A and Passage B?
Pick one of the five choices on the left. The explanation reveals after you commit.
The fix
- 01
Build two skeletons before reading the choices.
Write one sentence for each passage: what is the main claim? What is the evidence? What is the tone? This takes 60 seconds and prevents the one-passage trap on every question type.
- 02
Flag the relationship before looking at the choices.
After building both skeletons, name the relationship in your own words: agreement, disagreement, one extends the other, one rebuts the other. Then read the choices and match. If your named relationship does not match the credited answer, you misread one of the passages.
- 03
Drill relationship questions in isolation.
Take 15 Comparative relationship questions across different passage pairs. The pattern-recognition for one-passage-only traps locks in after repetition. This question type is rarely drilled in isolation because it appears only once per test.
The drill set adapts to your weakness.
Every RC Comparative item in Pinaka is tagged with one of seven sub-patterns. After your first mock, your skill map shows accuracy at the sub-pattern level: relationship, inference across both, function of element in both, comparative main point, author attitude, primary purpose, analogy/application. Drills sort by your weakest sub-pattern.
The five-section explanation on every Comparative item names which passage each distractor draws from and why the credited answer satisfies both. Building the two-skeleton habit on practice questions transfers directly to test day.
This is sample data. Your numbers arrive after one full mock. The chart shows your accuracy on each of the 21 LSAT subskills, with an evidence count on each. The lowest peak is where Pinaka starts your drilling.

RC Comparative Passages questions, answered.
How many Comparative Passage sets appear on the LSAT?
One. The Reading Comprehension section contains four passage sets. One of those four is always a Comparative Passage set with two shorter passages instead of one long passage. That set typically carries five to seven questions.
Should I read both passages before answering any questions?
Yes. Read Passage A, build a skeleton, then read Passage B, build a skeleton, then read the questions. Answering questions after only one passage is the fastest path to the one-passage-only trap. The extra 90 seconds to read the second passage saves more time than it costs.
What is the difference between a Relationship question and an Agreement question?
A Relationship question asks how the two passages relate overall: which describes the structural connection. An Agreement question asks for a specific claim that both authors would accept. Agreement questions require finding a claim that is simultaneously supported by both passages, not merely consistent with both.
How long should I spend on each Comparative Passage question?
Budget 8 to 9 minutes for the full set. First read: 3 to 4 minutes for both passages with skeleton notes. Then roughly 75 seconds per question. Relationship questions are usually faster once the skeletons are built. Inference-across-both questions take longer because you must verify both sides.
