- The author mentions increased purchases of untaxed fruit juices primarily in order to
Answer: support the point that consumer substitution can limit a tax's health effects and that policy design must consider responses across product categories
In this role of a detail question, we need to understand why the author discusses increased fruit juice purchases after soda taxes. The author introduces this example to "illustrate the substitution concern" raised in the previous paragraph—that taxes might encourage switching to other unhealthy products. The example demonstrates that when only sodas are taxed, consumers may substitute untaxed sugary fruit juices, potentially limiting the health benefits. Importantly, the author uses this to make a nuanced point: such findings don't prove taxes are "futile," but they do show that "policymakers should attend to product categories and consumer responses." Choice D captures this function perfectly—the example supports the broader point about considering substitution effects across product categories when designing tax policies. Choice B merely describes what happened without explaining why it matters to the argument, while choices A and E overstate what this single example can establish. Remember that details in LSAT passages rarely just convey information; they serve specific argumentative purposes within the author's broader analysis.
- The passage's reference to Justice Delgado's decision to leave a disliked precedent intact "for now" serves which one of the following functions?
Answer: To illustrate by example how selective restraint can protect legitimacy while laying groundwork for future change
The Delgado example concretely illustrates the advocated strategy of signaling a future direction while exercising restraint now. The other choices either misdescribe the passage's aim, treat the example as a definition or counterargument, or ascribe claims the author does not make.
- The author mentions the history of early antitrust statutes primarily in order to
Answer: illustrate how broad statutory language can invite judicial elaboration that is viewed by some as adaptive and by others as institutionally risky
In this role of a detail question, we need to understand why the author brings up antitrust law history in the fourth paragraph. The author isn't just mentioning that antitrust statutes used broad language—that's what the detail says, but not why it's included. The author uses this example to illustrate the "institutional concern" that critics have about dynamic interpretation: when courts interpret broad statutory language, they might create extensive doctrines that reflect judicial assumptions rather than legislative intent. This perfectly demonstrates how broad language can be seen as either adaptive (allowing judicial elaboration to make general terms workable) or institutionally risky (allowing judges to impose their own economic theories). Choice B captures this dual perspective and the illustrative function of the example. Choice D merely restates the detail without explaining its purpose, while choices A, C, and E either overstate the example's scope or mischaracterize the author's neutral presentation. Remember: always ask why the author includes a detail, not just what the detail says.
- The author mentions 'recent soil assays' primarily in order to:
Answer: highlight a piece of evidence that corrected a previous scientific misconception about native displacement.
The 'recent soil assays' are introduced immediately after 'initial ecological models assumed,' creating a direct contrast. The assays establish fungal network starvation as 'the primary mechanism of native displacement,' correcting the prior model. (A) is incorrect because the passage claims only that the fungal networks were desiccated, not that native bunchgrasses are inherently incapable of deep-soil absorption. (D) is out of scope; the passage does not address whether the water table will recover.
- In the passage, the statement that a 2019 municipal study found a 15 percent reduction in summer electricity use in neighborhoods with mature tree cover serves which one of the following functions?
Answer: It provides concrete empirical support for the claim that trees yield measurable cost savings.
The study is cited as specific evidence that canopy reduces electricity use, bolstering the author's cost-savings argument. The other choices either miscast it as a definition, concession, competing view, or a procedural description not at issue.
- The passage's mention of a 2019 meta-analysis finding substantial phylogenetic signal in climatic niche parameters serves which one of the following functions?
Answer: To supply empirical support for the claim that niche conservatism remains prevalent even when species' ranges shift rapidly
The meta-analysis is adduced as evidence that niche conservatism persists, bolstering the author's position. The other choices miscast it as a rejected model, a definition, a contrary exception, or a methodological critique.
- The author mentions sea-level rise primarily in order to
Answer: illustrate a slow-moving, long-horizon risk that can be undervalued by high discount rates, supporting the critique of standard discounting practices
This role of a detail question asks why the author mentions sea-level rise in the context of environmental discounting. The author uses this example to illustrate a slow-moving, long-horizon risk that can be undervalued by high discount rates, supporting the critique of standard discounting practices in environmental economics. Sea-level rise represents the kind of gradual but potentially catastrophic change that may seem 'unjustifiably expensive' to address if future costs are heavily discounted, even when prevention could avoid severe outcomes. This example supports the argument that 'standard discounting can undervalue harms borne by future generations' and illustrates why some propose lower rates for intergenerational problems. Choice B incorrectly treats this as merely restating environmental processes. Choice E overstates by suggesting discounting should be eliminated entirely. Focus on how specific examples reveal the policy implications of seemingly technical methodological choices.
- The passage's reference to a photographer whose image was wrongly treated as an orphan serves which one of the following functions?
Answer: To acknowledge a legitimate risk and motivate the inclusion of attribution and notice safeguards in the proposed framework
The anecdote functions as a caution that supports adding safeguards like attribution, registries, and penalties for bad faith. The other options either overstate the anecdote, contradict the passage's proposals, or misstate its evidentiary role.
- The author uses the 'sharp, chronological decline in Mediterranean forest species' primarily as evidence to support which of the following claims?
Answer: A severe drop in precipitation fundamentally altered the region's climate.
The sediment core data — the decline in forest species and rise in steppe flora — is introduced as evidence 'indicating a severe and prolonged drop in precipitation,' directly supporting the megadrought hypothesis. (A) directly contradicts the passage's argument, which positions the Sea Peoples as a consequence of the climate-driven collapse rather than a cause of environmental change. (B) is out of scope; the passage does not characterize palynological data as generally contradictory to ancient texts.
- The statistic that a 2019 citywide survey found 62% of residents used a pocket park at least once a week serves which one of the following functions?
Answer: To provide empirical support for the passage's claim that proximity enables frequent, cumulative use of small parks
It supplies evidence that frequent use is a distinctive advantage of small nearby spaces. The other options misstate the main point, mischaracterize the statistic, or describe different portions of the passage.
- In the second paragraph, the quotation from Justice Brandeis that "sunlight is said to be the best of disinfectants" serves primarily to do which of the following?
Answer: Invoke a concise historical endorsement of transparency to bolster the claim that oversight practices can legitimate agency action.
The quote lends rhetorical and historical support to the author's point that transparency-based tools can ground legitimacy. It neither states the main point, presents a counterargument, provides a definition, nor claims uniform judicial outcomes.
- What is the primary function of the discussion of the Mount Pinatubo eruption in the second paragraph?
Answer: To exemplify a natural experiment that helps calibrate model timescales and supports the argument for combining heterogeneous lines of evidence.
Pinatubo is presented as a useful quasi-experiment for calibrating model responses, illustrating the value of converging evidence. It is not used to discredit models, serve as a rejected analogy, provide the sole basis of an estimate, or claim volcanic dominance.
- The author mentions developers redirecting capital to unregulated housing markets primarily to provide evidence that:
Answer: rent price ceilings suppress the construction of new housing units in regulated areas.
Classical economists argue rent control 'suppresses the construction of new housing units,' and the developer behavior provides the mechanism: facing capped returns, developers 'predictably redirect their capital to unregulated housing markets.' The redirection is evidence for the supply-suppression claim. (A) represents the opposing advocate position, which the economist argument is challenging. (E) conflates housing misallocation — a secondary effect described in the second paragraph — with the supply-suppression claim the developer detail is introduced to support.
- The quoted observation that the herd will not cross when the river's 'skin' is sick serves which one of the following functions?
Answer: To exemplify an indigenous insight that, once translated into measurable terms, enhances the scientific model
The remark exemplifies a local observation that, when operationalized, becomes a valuable predictor in the model. The other options either misstate the passage's thesis, introduce limitations not tied to the quote, or denigrate metaphor in a way the author does not.
- The quoted language from the 1491 charter inviting apprentices to propose "new devices" under supervision serves which one of the following functions in the passage?
Answer: To offer a concrete instance that exemplifies the claim that some guilds institutionalized experimentation within safeguards
The quotation serves as a specific example of a guild formalizing supervised innovation, supporting the passage's thesis. The other options either mischaracterize the main point, introduce irrelevant context, or confuse the quote with a definition or counterexample.
- The author mentions that current regulatory protocols are 'designed for static chemical compounds' primarily to provide an explanation for:
Answer: why the approval process for phage therapeutics faces significant administrative hurdles.
The passage identifies the regulatory framework as 'a major bottleneck,' then gives the reason: 'current protocols were inherently designed for static chemical compounds.' The phrase explains why dynamic, evolving phage therapeutics face approval difficulties. (D) refers to the historical preference for penicillin described in the first paragraph — a separate development disconnected from the modern regulatory bottleneck. (A) is incorrect because the passage does not claim phage cocktails are frequently ineffective; it identifies regulatory approval as the obstacle, not clinical performance.
- The passage mentions that some judges privately admit uncertainty about applying custom without expert testimony primarily in order to do which of the following?
Answer: Motivate the proposed procedural reforms by highlighting a practical obstacle they are meant to address
The uncertainty illustrates a practical challenge that the proposed expert panels and training are designed to address. The other options distort the point by turning it into opposition, a critique of training, a counterexample to New Zealand, or a call to abdicate judging.
- In the third paragraph, the author's observation that auction prices for quilts remain far below those of comparably sized canvases serves primarily to do which of the following?
Answer: Underscore the persistence of institutional undervaluation despite growing recognition of quilts' aesthetic innovations.
The price comparison highlights enduring undervaluation even as curatorial attitudes shift. It does not weigh cultural resonance, claim indifference to medium, show full correction, or address costs.
- The author mentions cases in which a defendant rejected a plea offer of two years and later received twenty years primarily in order to
Answer: demonstrate how large sentencing differentials can create pressure to plead guilty, supporting critics' concerns about coercive incentives
To understand why the author mentions the two-years-versus-twenty-years example, we must examine its function in the plea bargaining discussion. The author introduces this example to "illustrate the pressure created by sentencing differentials" after explaining critics' concerns about coercive incentives in plea bargaining. The dramatic difference between the plea offer (two years) and the post-trial sentence (twenty years) demonstrates how the system can create overwhelming pressure to plead guilty, regardless of actual guilt. The author carefully notes that such examples don't prove every plea is coerced but "do clarify how the structure of incentives can influence choices independently of guilt." Choice A correctly identifies this function—the example demonstrates how large sentencing differentials create pressure that supports critics' coercion concerns. Choice C merely states what happened without explaining why it matters to the argument, while choice E overstates by claiming this supports abolishing plea bargaining entirely. The key is recognizing that this detail provides concrete evidence for the abstract concern about coercive incentives in the plea system.
- In the passage, the statement that the Riverside Guild's 1907 collection financed most of a new tuberculosis clinic serves which one of the following functions?
Answer: It illustrates the broader claim that community cookbooks functioned as tools for civic fundraising and activism.
The Riverside Guild example concretely exemplifies the passage's claim that such cookbooks financed civic projects. The other choices miscast it as a definition, a concession, a counterexample, or the main point itself.
