The Main Idea (Main Point)

  1. How it worksHow does an outline that builds paragraph by paragraph hand you the main point before you read a single answer choice?
  2. How it worksWhat is the difference between what an LSAT passage says and what its author is trying to do with it?
  3. Worked exampleWalk me through picking the main point when three paragraphs give a critic's view and one gives the author's rebuttal.
  4. Common mistakeWhy isn't the most-discussed detail in a text the same thing as its main point?
  5. Going furtherWhat changes about the main point when a final paragraph concedes something to the other side?

For 51 years after the statute's passage, appellate courts treated the phrase 'reasonable delay' as a question of fact for the jury. Commentators have read this as judicial modesty about the limits of review. The record suggests something narrower. Among the 72 published opinions of that period, the phrase appears almost exclusively where the trial record was incomplete; where the record was full, the same courts resolved the question themselves and said so. The modesty thesis thus describes a practice of triage rather than a doctrine of deference. When procedural reform made complete records routine, the phrase left the reports within a decade. Which one of the following most accurately expresses the main point of the passage?

Primary Purpose (the Author's Verb)

  1. How it worksHow do you test a purpose verb against the shape of a passage instead of against its topic?
  2. Worked exampleWalk me through choosing between 'describe a phenomenon' and 'argue for one explanation of it' as a primary purpose.
  3. Going furtherWhat happens to the purpose verb when an author adds a recommendation in the final two sentences?
  4. Common mistakeWhy doesn't a text that spends most of its words describing something have describe as its purpose?
Your turnmedium1 of 3
The 19 colonies studied divide labor by age: workers under 18 days old tend the brood, and older workers forage. Foragers die at 8 times the rate of nurses. Three explanations have been offered - hormonal timing, accumulated damage, and colony-level allocation of risk. The distribution of reversals settles the matter: when foragers are removed, nurses take up foraging within 3 days regardless of age, which no account keyed to the individual's own clock predicts. The primary purpose of the passage is to

Explicitly Stated Information (Detail)

  1. How it worksHow does a detail question's wording point you at one paragraph without rereading everything?
  2. How it worksWhat does paraphrase-matching mean when a correct detail answer shares almost no words with the text?
  3. Worked exampleWalk me through testing four choices against a line saying most, not all, surveyed firms reported a gain.
  4. Common mistakeWhy isn't a statement that is obviously true in the real world a correct answer to a stated-information question?
Your turneasy1 of 3
A survey of 315 firms in the licensing sector found that most, though not all, respondents reported a gain in net revenue in the year following the rule change, though the median gain was under 7 percent. Respondents in the smallest size band reported losses more often than gains. The surveying body cautions that participation was voluntary and that firms that had closed during the year could not respond. Its published summary states that the rule change 'coincided with' the reported gains; it makes no claim about what produced them. According to the passage, which one of the following is stated about the survey?

Information That Can Be Inferred

  1. How it worksHow do you draw the line exactly one step past what a text states without stepping two?
  2. Worked exampleWalk me through what must follow when every licensed lab uses the assay and one lab does not use it.
  3. Common mistakeWhy isn't the most likely real-world consequence of a text's facts a safe LSAT inference?
  4. Going furtherWhat changes about an inference question when the stem says most strongly supported instead of must be true?
Your turneasy1 of 3
The city's ordinance requires a permit for any structure over 39 feet, and the zoning board may issue a permit only after a public hearing. In the year just ended the board held 43 hearings and issued 19 permits. Which one of the following must be true on the basis of the passage?

Over-Reach and Scope on Inference Questions

  1. How it worksHow do words like all, only, never and cannot turn a plausible answer into an over-reach?
  2. How it worksShow me scope as a boundary drawn around exactly what a text licenses you to say.
  3. Common mistakeWhy doesn't a bland, weak-sounding answer choice get disqualified for saying too little?
  4. Worked exampleWalk me through why 'some geologists doubt the theory' is safe when 'the theory is doubtful' is not.
  5. Going furtherWhat happens to an over-reaching answer when one hedging word like sometimes is added back in?
Your turnmedium1 of 3
The isotope ratios in the 23 samples from the eastern outcrop are consistent with a hydrothermal origin, and three laboratories have reproduced them. A minority of geologists maintains that the same ratios arise from contamination during drilling, and one contaminated core has been documented. No study has yet measured the ratios in samples drilled with the newer sealed equipment, which the reviewing panel recommends. Which one of the following is most strongly supported by the passage?

The Meaning of Words and Phrases in Context

  1. How it worksHow do the sentences on either side of a word rotate its meaning until only one sense survives?
  2. Common mistakeWhy isn't a dictionary's first definition the answer to a meaning-in-context question?
  3. Worked exampleWalk me through what appropriated means where a later composer appropriated a folk melody without credit.
  4. Going furtherWhat changes when a stem asks for the purpose of a phrase rather than its meaning?
Your turneasy1 of 3
Critics of the period used 'plastic' as a term of praise: a plastic line was one the performer could reshape without breaking it. The word carried no suggestion of the synthetic, a sense that entered English usage some 75 years later. So when the critic writes that the phrasing of the younger players had grown 'plastic to the point of formlessness', the charge is not artificiality. It is the loss of a shape firm enough to be deformed. As it is used in the passage, 'plastic' most nearly means

The Organization or Structure of the Selection

  1. How it worksHow do you turn five paragraphs into a five-word skeleton like claim, objection, evidence, concession, verdict?
  2. Worked exampleWalk me through choosing between 'a theory is presented and then defended' and 'presented and then revised'.
  3. Common mistakeWhy isn't an organization answer correct just because everything named in it appears somewhere in the text?
  4. Going furtherWhat happens to a structure answer when two of its steps are swapped but every word stays the same?
  5. Ties togetherHow does one outline built while reading serve organization, main point and function questions at once?
Your turnmedium1 of 3
For 56 years the standard account held that the epidemic spread along trade routes. The account rests on a correlation between outbreak dates and caravan records. Two objections have been raised: the records survive for only 36 percent of the routes, and outbreaks appear at three sites no caravan reached. Proponents have answered the first objection by sampling, and have revised the account to admit a second vector for the three sites. The revised account is weaker than the original in one respect and stronger in another: it explains more cases and predicts fewer. Which one of the following most accurately describes the organization of the passage?

The Function of a Paragraph or Sentence

  1. How it worksHow do you name what a paragraph DOES rather than what it says?
  2. How it worksShow me how an example, a counterexample and a concession glow differently inside one outline.
  3. Worked exampleWalk me through the job of a paragraph on a failed 1890s experiment placed right before the author's proposal.
  4. Common mistakeWhy isn't summarizing a paragraph the same as answering what that paragraph is there for?
Your turnmedium1 of 3
Attempts to detect the drift began in the 1872s and continued for 46 years without result. The apparatus of the final attempt was sensitive to a shift 38 times smaller than the one predicted, and its null result was not seriously disputed. I do not rehearse this history to argue that the drift does not exist. I rehearse it because the experiments were designed around a single assumption about the medium, and the proposal I make below abandons that assumption while keeping everything else those designers believed. The author's account of the 46-year sequence of attempts functions primarily to

Applying Information to a New Context

  1. How it worksHow do you lift a criterion out of a text and test four unfamiliar cases against it?
  2. Worked exampleWalk me through applying a definition of restorative justice to an offender who repays a victim under court order.
  3. Going furtherWhat changes when an application question asks which case an author would reject instead of accept?
  4. Common mistakeWhy isn't the most sympathetic new case the one an author's stated standard actually picks out?
Your turnmedium1 of 3
On the account defended here, a sanction is restorative when three conditions hold: the offender performs the repair personally, the victim's specification of the harm governs what counts as repair, and the offender's participation is not secured by the threat of a heavier penalty. Programs that satisfy the first two conditions but not the third are common; in 17 of the 34 jurisdictions surveyed, participation is offered in place of a custodial term. Which one of the following sanctions counts as restorative on the account defended in the passage?

Principles That Function in the Selection

  1. How it worksHow do you climb from one specific judgment an author makes to the general principle underneath it?
  2. How it worksWhat makes a candidate principle too broad or too narrow to be the one a text runs on?
  3. Worked exampleWalk me through the principle behind a critic who praises one restoration and condemns another done the same way.
  4. Common mistakeWhy isn't a true and widely accepted moral rule the right answer when a text never relies on it?
  5. Going furtherWhat happens when a principle question runs backwards and hands you the rule to apply?
Your turnmedium1 of 3
The critic praises the restoration of the north transept, in which 40 percent of the original stone was replaced, and condemns the restoration of the nave, in which 20 percent was replaced by the same firm using the same method. The difference she draws is not one of degree. The transept's replacements are cut to a profile documented in the fabric rolls; the nave's are cut to a profile the restorer inferred from what he took to be the builder's intention. Which one of the following principles underlies the critic's two judgments?

Analogies to Claims or Arguments in the Selection

  1. How it worksHow do you strip an argument to a skeleton so it can be laid over a completely different situation?
  2. Worked exampleWalk me through matching 'a cure works only because patients expect it to' to its closest everyday parallel.
  3. Common mistakeWhy isn't the answer choice about the same subject matter the closest analogy?
  4. Going furtherWhat changes when an analogy has to match an author's method rather than an author's claim?
Your turnmedium1 of 3
The author's claim about the treatment is this: it produces its effect in 64 percent of patients, but the effect is produced by the patient's expectation rather than by the compound, and the compound is needed because nothing else sustains that expectation over the 8 weeks the effect takes to appear. Which one of the following is most closely analogous to the author's claim about the treatment?

The Author's Attitude, Revealed in Tone and Language

  1. How it worksHow do word choices rotate an attitude dial from admiring through neutral to dismissive?
  2. How it worksWhat separates critical from skeptical, and ambivalent from dismissive, in an attitude answer choice?
  3. Worked exampleWalk me through the attitude behind 'a promising if still largely unsubstantiated line of inquiry'.
  4. Going furtherWhat happens to an attitude answer when an author is warm toward a goal but cold toward the method?
  5. Common mistakeWhy isn't an author hostile just because a whole paragraph lays out an objection?
Your turnmedium1 of 3
The program's designers set out to reduce the caseload in 12 districts, and the aim was overdue. The instrument they chose was a survey administered at intake, which the designers describe as validated; the validation consisted of 15 interviews conducted by the designers themselves. Nothing in the published account suggests bad faith. It suggests, rather, that an ambition worth pursuing was entrusted to a measure no one outside the project has tested. The author's attitude toward the program is most accurately described as

The Impact of New Information on Claims

  1. How it worksHow do you find the one claim in a text that a new piece of evidence actually touches?
  2. Worked exampleWalk me through what it does to a claim that lead pipes caused a decline if the decline began before the pipes did.
  3. Worked exampleFind which new result most strengthens a claim that a drug works, given a trial where the placebo group also improved.
  4. Common mistakeWhy doesn't new evidence against a view the author merely reports weaken the author's own argument?
Your turnmedium1 of 3
Rates of the disorder in the city fell by 37 percent between the two surveys. The author attributes the fall to the replacement of the water pipes, which began in the year of the first survey and finished 9 years later. Critics attribute it instead to the closure of the smelter in the same period. The author replies that the decline is steepest in the districts where replacement came first. Which one of the following, if true, most weakens the author's reply to the critics?

Prep-Industry Question Names vs. LSAC's Ten Targets

  1. How it worksHow do LSAC's ten reading targets map onto the names tutors use, like Main Point and Vocabulary-in-Context?
  2. How it worksShow me how to read a question stem and route it to the right target in under three seconds.
  3. Common mistakeWhy isn't there an official LSAT list of reading question types with tidy names on it?
  4. Going furtherWhat happens when one stem hits two targets at once, like function and attitude together?
Your turneasy1 of 3
A commercial prep book prints 11 named reading question types and tells its readers that these are the official LSAT categories, so that each of the 28 stems in an official section must fall under one of them. Which one of the following is the most accurate correction of the book's claim?

The Recurring Wrong-Answer Shapes

  1. How it worksHow does a too-strong answer differ from an out-of-scope one when both feel wrong?
  2. How it worksShow me the half-right trap, where an answer's first clause is perfect and its last three words are fatal.
  3. Worked exampleWalk me through separating an answer that reverses cause and effect from one that merely overstates a degree.
  4. Common mistakeWhy isn't a reversed answer easy to catch when every word in it appeared in the text?
  5. Ties togetherHow do reading trap shapes line up with the trap shapes on logical reasoning questions?

The 93 inscriptions from the site record grain payments, not sales, and the quantities rise in each of the 16 years they cover. The excavator infers a growing population. A rise in recorded payments would also follow from a change in what the administration chose to record, and the last 6 years of the sequence coincide with a new scribal hand. Which one of the following answer choices would be wrong because it claims more than the passage supports, rather than because it raises a matter the passage does not discuss?
