Key takeaway

What to remember about The three RC traps

Reading Comprehension misses cluster into three trap families. Author-attitude substitution swaps the author for a passage figure. Cross-paragraph inference gaps break the bridge between non-adjacent paragraphs. Off-by-one detail errors match the topic but swap the predicate. Structural tagging during the read catches all three before the question stem.

Reading Comprehension misses are not random. Most fall into three trap families that recur across passages, mocks, and prep tests. A student who learns to name the traps stops falling in. A student who does not learn calls the misses careless and lets the pattern repeat for months.

The traps are not a knowledge problem. They are a reading-habit problem. The fix is structural and takes about two weeks to install.

Tagged paragraphs catch traps. Memorized content does not.

Why these three traps recur

LSAC writes RC passages that present multiple viewpoints. The author is one viewpoint among several. The passage describes a debate, presents arguments from two or three positions, and signals the author stance through word choice rather than direct statement. A reader who reads for content remembers the debate but loses the author. A reader who tagged the paragraphs separates the author from the debate.

Right answers on RC inference items are usually a combination. The right answer combines two non-adjacent paragraphs. The combination is the inference; neither paragraph contains the right answer alone. A reader who reads for content has no bridge between the paragraphs. A reader who tagged each paragraph function has the bridge already.

The right answer to a detail item depends on the exact pairing of subject and predicate in the passage. The passage states X about weekdays and Y about weekends. The trap distractor states X about weekends. A reader who relies on memory of what was in there picks by topic. A reader who returns to the passage and locates the sentence picks by line.

A four-word tag per paragraph builds a sixteen-word skeleton in twelve seconds.

Three trap families to name

Naming each trap by tell and fix is the first step. The fix in every case is the same habit: tag every paragraph in two or three words on first read.

Three traps to name and catch
  1. Author-attitude substitution. A student picks the viewpoint that appears most often in the passage. Fix: return to the paragraph tagged as the author voice. Pick the stance that paragraph signals.
  2. Cross-paragraph inference gap. A student searches for the right answer in one paragraph. Fix: combine the two paragraph tags the stem references. The bridge is the inference.
  3. Off-by-one detail error. A student picks by topic match. Fix: return to the passage and find the sentence. Match subject and predicate exactly.
Where this hits the skill map

This post connects to RC Inference and RC Detail. The three traps split across the two skill nodes: author-attitude and cross-paragraph inference sit under RC Inference; off-by-one detail sits under RC Detail. The skill map drills each node separately, then mixed.

A real RC trap-drill plan

The plan is one habit, applied to every passage. Tag every paragraph in two or three words on first read. The table below shows the three misses and the read that prevents each.

Each trap, the read that falls into it, and the read that catches it.
On author-attitude, pick the viewpoint that appears most often in the passage.On author-attitude, return to the paragraph tagged as the author voice. Pick the stance that paragraph signals.Multiple viewpoints appear in the passage. Only one is the author. The frequency trap chooses the most discussed view, not the authored view.
On cross-paragraph inference, search for the right answer in one paragraph.On cross-paragraph inference, combine the two paragraph tags the stem references. The bridge is the inference.The right answer is a combination. Single-paragraph search returns wrong answers that are true of one paragraph but not of the combination.
On detail items, pick by topic match.On detail items, return to the passage. Find the sentence. Match subject and predicate exactly.The off-by-one distractor matches the topic but swaps the subject. Subject-predicate verification catches it; topic match does not.

The worked example

The question below is an RC Inference item. Watch for the cross-paragraph bridge. The right answer is not contained in any single paragraph. It is a combination of what one paragraph establishes and what a later paragraph qualifies. A reader who tagged the paragraphs on first read has the bridge already.

At Pinaka Books on Pennsylvania Avenue, owner Maya tested three pricing strategies in different sections last quarter. The fiction section used full-retail prices. The history section offered subscribers a 10% discount. The legal-reference section used dynamic prices that adjusted weekly based on demand.

After three months, fiction sales were unchanged. History sales rose 8%, but the lift came almost entirely from existing subscribers; new-subscriber growth was negligible. Legal-reference sales rose 4% and held steady regardless of price changes; legal-reference customers, Maya observed, treat price as a secondary factor when buying technical materials.

Maya is now considering which model to expand store-wide. Sam has argued for the subscriber-discount model on the grounds that it produced the largest sales lift. Maya is more cautious. She notes that the lift came from existing subscribers rather than new ones, and that the legal-reference data suggests price may not be the strongest lever for sales in every section.

Which one of the following is most strongly supported by the information in the passage?

(A)Maya prefers the dynamic-pricing model over the subscriber-discount model.Your answer
(B)The legal-reference section demonstrates that pricing strategy is irrelevant for technical materials.
(C)Sam treats the size of a sales lift as his primary criterion for evaluating pricing strategies.Correct
(D)Existing subscribers are more sensitive to price changes than new subscribers are.
(E)Maya plans to apply the dynamic-pricing model across all sections at Pinaka Books.
Wrong
You picked (A). The correct answer is (C).
Short answer

Sam’s stated rationale ("it produced the largest sales lift") implies size of lift is his criterion. Option (C) names what his rationale implies.

01Per-option diagnosis
(A)distortionCaution about one model is not preference for another. The passage says what makes Maya cautious, not what she prefers.
(B)distortion"Irrelevant for technical materials" overstates "price may not be the strongest lever in every section."
(C)correctSam argued for the model on the grounds it produced the largest lift. His stated rationale implies size-of-lift is his primary criterion.
(D)out_of_scopeThe passage says the lift came from existing subscribers, not that they are more sensitive to price than new subscribers.
(E)out_of_scopeThe passage says Maya is considering which model to expand, not that she plans the dynamic-pricing model.
02Approach

Inference questions reward what the passage strictly supports. Find the option whose claim is anchored in a specific passage statement. Sam’s stated rationale is the anchor for (C).

03Take-home

Distinguish what the passage says from what it suggests. Inference is supported, not implied. Caution is not preference. Lift-size as rationale is what is stated.

04Timing

75-100 seconds. Eliminate (D) and (E) on unsupported. (A) trades caution for preference. (B) overstates. (C) is anchored in Sam’s rationale.

Common questions

What are the most common RC trap answers?

Three patterns recur: out-of-passage detail (a real-world plausible claim the passage does not actually support), cited view confused with author view, and cross-paragraph inference picked from a single paragraph. Naming the trap type before elimination prevents the most common misses.

How do I avoid out-of-passage detail traps?

Anchor each answer choice to a specific line. If you cannot point to the line, the choice is unsupported, regardless of how plausible it sounds in the real world. The passage is the only evidence on Reading Comprehension.

What is a cross-paragraph inference?

An inference whose answer combines content from two non-adjacent paragraphs. Neither paragraph contains the answer alone; the combination is the inference. A reader who tagged each paragraph function has the bridge ready.

How can I improve my RC trap-recognition speed?

Drill RC questions with the answer hidden. Tag each distractor with its trap type before checking the credited answer. After ten questions, the tag itself becomes the elimination move.

Next steps

Tag the trap type before you eliminate.

When a miss happens, name which trap it was. Author-attitude, cross-paragraph inference, or off-by-one detail. Three traps. Same diagnostic move. Tag the swap.
