Main Idea Primary PurposeQuestion 1 of 20

Read the passage and answer the question.

In the arts, originality is often treated as the highest virtue, leading to the suspicion that imitation is inherently inferior. Yet imitation can be a method of learning and even a source of innovation. Artists frequently begin by copying established techniques, not to produce replicas for their own sake but to internalize constraints and develop control. Moreover, many celebrated "original" works are transformations of existing forms: they recombine familiar elements or shift them into new contexts. The more useful distinction, then, is not between originality and imitation but between unreflective copying and purposeful adaptation. When creators understand what they borrow and why, imitation becomes a tool for generating variation rather than a barrier to it. Evaluating creativity requires attention to process and intent, not just to whether a work appears unprecedented.

The author's main objective is to:

Argue that originality is meaningless and that all artworks are identical copies of earlier works

Explain that imitation can support learning and innovation, and propose a more nuanced way to evaluate creativity

Provide a detailed history of artistic movements in order to rank them by originality

Offer a topic-only discussion of art by mentioning originality, imitation, and technique without making a claim

Criticize museums for displaying derivative works instead of only unprecedented masterpieces

All questions

Question 1

Read the passage and answer the question.

The author's main objective is to:

Argue that originality is meaningless and that all artworks are identical copies of earlier works
Explain that imitation can support learning and innovation, and propose a more nuanced way to evaluate creativity (correct answer)
Provide a detailed history of artistic movements in order to rank them by originality
Offer a topic-only discussion of art by mentioning originality, imitation, and technique without making a claim
Criticize museums for displaying derivative works instead of only unprecedented masterpieces

Explanation: This question tests the author's main objective by identifying the passage's primary aim. A correct objective answer should encompass re-evaluating imitation's role in creativity. The passage develops this by challenging suspicion of imitation, with examples of learning and transformation. It proposes distinguishing unreflective copying from adaptation, focusing on process. Choice B captures the nuanced evaluation and support for imitation. In contrast, choice A is a distractor that overstates by denying originality, unlike the passage's balanced view. Choice D is too neutral, offering a survey without the claim, missing the argumentative core.

Question 2

Passage: In discussions of language change, prescriptive commentators often portray new usages as signs of decline, implying that a language has a correct, stable form that is being corrupted. The passage evaluates this view by contrasting it with a descriptive perspective, which treats variation and change as normal features of living languages. The author notes that standards can be socially useful: shared conventions facilitate communication in formal settings and can reduce ambiguity. Yet the passage argues that elevating one variety as inherently superior often reflects historical power relations rather than linguistic necessity, and it can stigmatize speakers whose dialects differ from the standard. The author concludes that a balanced approach recognizes the practical role of standards while rejecting the notion that change itself is evidence of decay.

Question: The author's main objective is to…

provide a list of recent slang terms that have entered the language and explain their origins
argue that language standards are useless and should be eliminated from schools
discuss language change
evaluate prescriptive and descriptive views of language by acknowledging the utility of standards while disputing that change signals decline (correct answer)
criticize descriptive linguists for ignoring the need for clarity in formal writing

Explanation: This question tests primary purpose, asking for the author's main objective in discussing language change. A correct answer must identify the specific evaluative argument being made rather than just stating the topic. The passage develops its argument by contrasting prescriptive views (which see change as decline) with descriptive views (which see change as normal), then evaluating both perspectives. The author acknowledges the utility of standards for formal communication while rejecting the notion that language change represents decay, ultimately advocating for a balanced approach. Choice D correctly identifies this primary purpose by stating the author evaluates prescriptive and descriptive views while acknowledging standard utility but disputing that change signals decline. Choice C is too vague and merely identifies the topic, while choice B misrepresents the author's position by suggesting standards should be eliminated, when the passage actually acknowledges their practical value.

Question 3

Read the passage and answer the question.

In many workplaces, "productivity" is treated as a single, easily measured quantity, often proxied by hours logged or tasks completed. Yet these metrics can obscure the distinction between activity and value. A team may increase output by producing more reports, emails, or meetings, while simultaneously reducing the time available for analysis and decision-making. Some managers respond by introducing tighter monitoring, assuming that visibility will deter wasted effort; however, heightened surveillance can prompt employees to optimize for what is measured rather than for what matters, such as long-term problem prevention or creative experimentation. A more informative approach separates productivity into at least two components: efficiency (how quickly resources are converted into deliverables) and effectiveness (whether the deliverables advance the organization's goals). This distinction clarifies why certain interventions—like reducing unnecessary meetings, improving documentation, or empowering employees to decline low-impact requests—can raise effectiveness even if they lower visible activity. The point is not that measurement is futile, but that organizations should choose indicators that align with desired outcomes and remain alert to behavioral shifts caused by the indicators themselves.

Which of the following best describes the main idea of the passage?

To argue that workplace surveillance is inherently counterproductive and should be eliminated in all organizations
To explain why common productivity metrics can mislead and to propose a framework that distinguishes efficiency from effectiveness (correct answer)
To describe various tools managers use to track employee activity, such as monitoring software and time sheets
To recommend that organizations maximize the number of deliverables produced per week regardless of their strategic value
To provide a comprehensive theory of organizational behavior that explains all employee motivation across industries

Explanation: This question tests the main idea of the passage by asking for the best description of its central focus. A correct main idea answer should capture the passage's overall argument without being too narrow or too broad, encompassing the key critique and proposed alternative. The passage develops this by critiquing simplistic productivity metrics like hours or tasks, which can obscure value, and by discussing how surveillance may exacerbate the issue. It then introduces a distinction between efficiency and effectiveness, using examples like reducing meetings to illustrate how this framework improves understanding. Choice B justifies this as the main idea because it accurately reflects the passage's emphasis on misleading metrics and the proposed separation of components to better align with organizational goals. In contrast, choice A is too extreme, as the passage does not argue for eliminating all surveillance but rather for more thoughtful measurement. Similarly, choice C is too narrow, focusing only on describing tools without addressing the broader critique and framework.

Question 4

Read the passage and answer the question.

Some educators advocate "learning styles" instruction, in which students are categorized as visual, auditory, or kinesthetic learners and taught accordingly. The appeal is intuitive: if instruction matches a student's preferred mode, learning should improve. However, preference is not the same as effectiveness. A student may enjoy listening to lectures yet retain more from solving problems, and certain subjects constrain which modes are feasible—for instance, geometry requires working with diagrams regardless of preference. Moreover, the strongest test of the learning-styles hypothesis is not whether students report liking a matched format but whether matched instruction produces better outcomes than mismatched instruction. Reviews of experimental studies have found little consistent support for that interaction. This does not imply that varied instruction is useless; multiple representations can aid understanding and engagement. The more cautious conclusion is that teachers should diversify methods because content and practice matter, not because students can be reliably sorted into stable learning-style categories.

Which of the following best describes the main idea of the passage?

To argue that students should be required to learn only through the method they like best
To outline the three main learning-style categories and provide classroom activities for each
To critique the strong version of learning-styles instruction while endorsing varied teaching for other reasons (correct answer)
To prove that all educational psychology research is unreliable due to flawed experiments
To discuss student preferences in general without evaluating whether they affect learning outcomes

Explanation: This question tests the main idea of the passage by asking for its best description. A correct main idea answer should summarize the critique of a concept and a qualified endorsement of alternatives. The passage develops this by outlining learning-styles theory, then critiquing its evidential basis and assumptions like preference equaling effectiveness. It further contrasts this with benefits of varied instruction for content reasons, not style categories. Choice C captures the passage as a whole by highlighting the critique of the strong hypothesis while supporting diversification for other reasons. In contrast, choice A fails as too extreme, recommending only preferred methods, which the passage rejects. Similarly, choice D is overly broad and absolute, claiming all research is unreliable, unlike the passage's targeted review of studies.

Question 5

Read the passage and answer the question.

In literary criticism, a long-standing debate concerns whether interpretation should prioritize authorial intent or the text's effects on readers. Advocates of intent argue that ignoring the author's aims invites arbitrary readings; advocates of reader response counter that texts acquire meanings in diverse contexts the author could not control. The debate often stalls because it treats "meaning" as a single thing. One can distinguish at least three questions: what the author likely meant, what the text's language can reasonably support, and what responses the text tends to elicit in particular communities. These questions can conflict, but they need not be collapsed into one criterion. For instance, establishing likely intent may clarify historical context, while examining reader response may illuminate why a work remains influential. A pluralistic approach does not declare all interpretations equally valid; it instead evaluates claims by the standards appropriate to the question being asked.

The passage is primarily concerned with which of the following?

Arguing that only authorial intent matters and that reader-response criticism is illegitimate
Explaining that the intent-versus-reader debate can be clarified by distinguishing different senses of "meaning" and adopting a pluralistic framework (correct answer)
Providing detailed interpretations of a particular novel to demonstrate the superiority of one critical method
Offering a topic-only survey of literary criticism without advancing a claim about interpretation
Claiming that all interpretations are equally valid because texts have no stable language

Explanation: This question tests the primary concern of the passage by asking for its main focus. A correct answer should reflect clarifying a debate through distinctions and pluralism. The passage develops this by outlining intent versus reader positions, then distinguishing senses of meaning. It proposes evaluating claims by appropriate standards, using examples like historical context. Choice B encapsulates the passage's nuanced framework for the debate. For instance, choice A is a distractor that takes an extreme side, prioritizing intent only, unlike the passage's pluralism. Choice E fails by claiming all interpretations equal, contradicting the passage's standards.

Question 6

Read the passage and answer the question.

In discussions of scientific progress, a common image is that of a steady accumulation of facts. Yet many advances occur not by adding data but by revising the questions that data are meant to answer. When researchers inherit a standard measurement, they may treat it as neutral, even though it embodies assumptions about what matters. For example, a single index might combine several dimensions into one score, simplifying comparison but masking trade-offs among components. In such cases, collecting more observations can refine the score without clarifying whether the score captures the phenomenon of interest. Progress may require disaggregating the index, creating alternative measures, or even redefining the target concept. This is not an argument against quantification; rather, it is a reminder that measurement is an interpretive act. Scientific debates often hinge less on whose numbers are larger than on whether the numbers correspond to an adequate framing of the problem.

The author's main objective is to:

Demonstrate that all scientific indices are deceptive and should be abandoned in favor of qualitative judgment
Describe the history of measurement in science from early astronomy to modern statistics
Explain that scientific progress often involves revising measurement and framing, not merely accumulating more data (correct answer)
Provide step-by-step instructions for constructing a composite index that avoids trade-offs among components
Discuss scientific progress without making any claim about the role of measurement

Explanation: This question tests the author's main objective by seeking the passage's primary aim. A correct answer should capture the emphasis on revising measurement for scientific progress, rather than just data accumulation. The passage develops this by challenging the accumulation view and illustrating with examples like indices that mask trade-offs. It further explains that progress involves disaggregating measures or redefining concepts, framing measurement as interpretive. Choice C justifies this as the main objective because it encompasses the passage's focus on reframing questions and measurement for advances. For example, choice A is a distractor that overstates by claiming all indices are deceptive and should be abandoned, while the passage supports quantification with revisions. Choice D is too narrow, offering instructions not present in the passage, which instead discusses broader principles.

Question 7

Passage: When cities consider planting more trees to address summer heat, advocates sometimes imply that tree canopy is a universal remedy. The passage agrees that shade and evapotranspiration can lower local temperatures, but it emphasizes that the effect depends on placement, species, and surrounding infrastructure. For example, dense canopy over asphalt parking lots may reduce surface temperatures substantially, whereas scattered trees along wide, windy corridors may yield only modest cooling. The author also notes potential trade-offs: some species emit compounds that can contribute to ozone formation under certain conditions, and increased pollen can worsen allergies. Rather than treating tree planting as a symbolic gesture, the passage argues for integrating it with broader heat-mitigation strategies such as reflective materials and building design, and for evaluating outcomes with neighborhood-specific data.

Question: Which of the following best describes the main idea of the passage?

City governments should prioritize reflective roofing over planting trees because roofing has fewer trade-offs.
Tree planting can help reduce urban heat, but its benefits and drawbacks vary by context and should be planned as part of a broader strategy. (correct answer)
The passage catalogues every major method cities use to mitigate heat.
The passage is about urban trees and summer temperatures.
Dense canopy over asphalt parking lots produces the largest temperature reductions among common planting sites.

Explanation: This question tests main idea identification, requiring recognition of the passage's central claim about urban tree planting. A correct main idea answer must capture both the benefits acknowledged and the limitations discussed throughout the passage. The passage develops its central point by first acknowledging that trees can reduce urban heat through shade and evapotranspiration, then systematically presenting various contextual factors that affect their effectiveness. The author emphasizes placement, species selection, and potential trade-offs like ozone formation and allergies, ultimately arguing for a nuanced, data-driven approach. Choice B correctly captures this main idea by stating that tree planting can help but its benefits and drawbacks vary by context and require broader strategic planning. Choice A is too narrow, focusing only on one comparison mentioned in the passage, while choice D is too vague and fails to capture the passage's nuanced argument about contextual variability.

Question 8

Read the passage and answer the question.

In discussions of employee performance, managers often treat "motivation" as a stable trait that some workers possess and others lack. This view encourages interventions aimed at selecting inherently driven individuals rather than improving working conditions. Yet research on goal pursuit suggests that motivation is highly sensitive to context: people exert more effort when tasks are clearly defined, when feedback is timely, and when they can see how their work contributes to a larger outcome. Importantly, these contextual supports do not merely increase effort; they can also change what employees interpret as success. For example, when feedback emphasizes learning and iteration, workers may persist through early failure because progress is framed as skill development rather than as evidence of inadequacy.

However, the passage does not claim that context eliminates individual differences. Some workers may still respond more strongly than others to the same conditions, and long-term interests can shape which tasks feel meaningful. The central point is that organizations err when they treat motivation as a fixed internal resource. A more effective approach is to view motivation as an interaction between individuals and environments, making it possible to design workplaces that reliably elicit sustained engagement.

The primary purpose of the passage is to:

argue that employee motivation is largely shaped by workplace conditions and should be addressed through environmental design rather than treated as a fixed trait (correct answer)
provide a comprehensive overview of all known psychological theories of motivation and their implications for hiring
describe the topic of motivation in workplaces and mention several factors that influence it
demonstrate that individual differences are irrelevant once organizations provide clear goals and timely feedback
criticize managers for intentionally misusing the concept of motivation to justify poor treatment of employees

Explanation: This question tests your ability to identify the main idea or primary purpose of a passage. A correct main idea answer should capture the central argument or thesis that the entire passage develops, not just a detail or partial aspect. The passage develops the central point that motivation should be viewed as context-dependent rather than as a fixed trait, arguing that organizations should focus on environmental design rather than just selecting supposedly motivated individuals. The passage supports this by explaining how contextual factors like clear goals and timely feedback affect motivation, while acknowledging that individual differences still exist. Answer A correctly captures this primary purpose by stating that the passage argues motivation is shaped by workplace conditions and should be addressed through environmental design rather than treated as a fixed trait. Answer C is too vague and merely describes the topic without capturing the specific argument, making it a classic "too general" distractor that fails to identify the author's actual position on the issue.

Question 9

Read the passage and answer the question.

Some commentators claim that the spread of digital reading inevitably diminishes comprehension because screens encourage skimming. The evidence, however, is more mixed than the claim suggests. Studies that compare print and screen often find small average differences, but those averages conceal substantial variation depending on task and design. When digital texts are presented with frequent notifications, hyperlinks, or infinite scrolling, readers are more likely to fragment attention and retain less. Yet when distractions are minimized and the interface supports navigation—through stable page numbers, clear headings, and easy annotation—screen reading can yield comprehension comparable to print. Moreover, the medium itself does not determine reading goals: people often choose screens for quick reference and print for sustained study, and then attribute the resulting differences to the medium rather than to their intentions. The more defensible conclusion is that comprehension depends less on "screen versus paper" than on how the reading environment shapes attention and how well the format supports the reader's purpose.

The primary purpose of the passage is to:

Show that print reading is always superior to digital reading because it prevents distraction
Summarize the history of digital interfaces and their evolution from early e-readers to modern tablets
Explain that claims about digital reading harming comprehension are overstated and that design and goals mediate outcomes (correct answer)
Argue that readers should abandon screens entirely in favor of paper for all serious reading tasks
Discuss digital reading in general without taking a position on whether comprehension differs by medium

Explanation: This question tests the primary purpose of the passage by requiring identification of the author's main goal. A correct primary purpose answer should encapsulate the passage's intent, such as qualifying a claim and providing a nuanced view, rather than listing facts or taking an absolute stance. The passage develops this by countering the claim that digital reading always harms comprehension, citing mixed evidence and factors like design and goals. It further elaborates with examples of when screens hinder or support reading, emphasizing that outcomes depend on environment and purpose. Choice C captures the passage as a whole by highlighting the overstated claims and the mediating roles of design and goals, aligning with the author's balanced conclusion. For instance, choice A is a distractor that fails because it is too absolute, claiming print is always superior, which the passage refutes by noting comparable outcomes in well-designed digital formats. Likewise, choice D overstates by recommending abandoning screens entirely, ignoring the passage's nuanced support for context-dependent use.

Question 10

Read the passage and answer the question.

When policymakers consider regulating a new technology, they often face a dilemma: acting early can prevent harms from becoming entrenched, but acting too early can freeze innovation around premature assumptions. One response is to delay until evidence accumulates; yet delay can itself shape the market, allowing dominant designs and business models to set norms that later regulation struggles to change. Another response is to regulate principles rather than mechanisms—for example, focusing on transparency, accountability, and consumer choice—so that rules remain relevant as technical details evolve. Still, principle-based regulation can be criticized as vague, leaving firms uncertain about compliance. The most promising strategies therefore combine adaptive mechanisms, such as periodic review and sunset clauses, with targeted requirements in high-risk contexts. The goal is not to find a timeless rule but to create institutions that can learn, revise, and respond as both benefits and harms become clearer.

The primary purpose of the passage is to:

Recommend a single fixed regulatory rule that should govern all technologies regardless of context
Explain the trade-offs in regulating emerging technologies and suggest adaptive, mixed approaches (correct answer)
Describe the technical workings of new technologies in order to show why regulation is impossible
List specific examples of past technology laws and the dates they were enacted
Argue that regulation should always be postponed until a technology is fully mature

Explanation: This question tests the primary purpose of the passage by identifying the author's main intent. A correct purpose answer should reflect the discussion of dilemmas and suggestions for balanced approaches. The passage develops this by outlining trade-offs in early versus delayed regulation and critiquing extremes like vague principles. It proposes adaptive strategies like reviews and targeted requirements to handle evolving technologies. Choice B encapsulates the passage's focus on trade-offs and mixed approaches, covering the analysis and recommendations. For instance, choice A is a distractor that fails by being too rigid, recommending a single rule, which contradicts the passage's emphasis on adaptability. Choice E is too one-sided, advocating always postponing regulation, while the passage notes risks of delay.

Question 11

Passage: In debates about scientific replication, one side interprets failed replications as evidence that original studies were careless or even fraudulent. The passage argues for a more cautious interpretation. A replication attempt may differ subtly from the original—using a different population, measurement instrument, or laboratory context—and such differences can matter when effects are sensitive to conditions. Moreover, the passage notes that even genuine effects can appear inconsistent because estimates vary with sample size and random noise; a single study rarely pins down an exact magnitude. The author maintains that replication is essential, but primarily as a means of mapping when and where an effect occurs, not as a simplistic pass–fail test of a study's legitimacy. The passage concludes that the most productive replication culture emphasizes transparency, shared data, and cumulative evidence.

Question: The primary purpose of the passage is to…

argue that replication should be used to understand the conditions and variability of effects rather than to issue simple judgments about original studies (correct answer)
describe in detail the statistical formulas needed to compute sampling error
discuss replication in science
claim that most failed replications prove scientific fraud is widespread
explain how differences in measurement instruments alone account for all replication failures

Explanation: This question tests primary purpose, asking for the author's main objective in discussing scientific replication. A correct answer must identify the specific argument being made rather than just the general topic. The passage develops its argument by first presenting the simplistic view that failed replications indicate fraud or carelessness, then systematically explaining why this interpretation is problematic due to contextual differences and natural variability. The author advocates for using replication to understand conditions and variability rather than making simple pass-fail judgments. Choice A correctly identifies this primary purpose by stating the author argues replication should be used to understand conditions and variability rather than issue simple judgments. Choice C merely identifies the topic without capturing the specific argument, while choice D misrepresents the author's position by suggesting failed replications prove widespread fraud, which directly contradicts the passage's cautious interpretation.

Question 12

Read the passage and answer the question.

Organizations sometimes treat innovation as the product of sudden inspiration, emphasizing individual creativity while downplaying routine processes. The passage argues that this emphasis can obscure the extent to which innovation depends on systems that make experimentation affordable. When teams can prototype quickly, share partial results, and learn from small failures, they generate more usable ideas than when they wait for fully formed breakthroughs. In this account, innovation is less a rare event than a managed pipeline of trials, feedback, and revision.

The passage acknowledges that not all experimentation is valuable: without clear criteria, organizations can produce activity without progress. But it contends that the solution is not to abandon experimentation in favor of "genius-led" innovation; rather, leaders should define goals, track learning, and allocate resources to the most promising directions. The passage concludes that treating innovation as a process helps organizations build repeatable capabilities instead of relying on unpredictable moments of inspiration.

The passage is primarily concerned with which of the following?

arguing that innovation is primarily determined by hiring exceptionally creative individuals rather than by changing organizational processes
explaining that innovation can be cultivated through structured experimentation and feedback systems, not merely through sporadic inspiration (correct answer)
describing the topic of innovation and mentioning that prototyping, failure, and resource allocation are involved
providing a detailed set of metrics for ranking prototypes across industries and determining which ideas should be funded
criticizing organizational leaders for intentionally discouraging creativity by imposing goals and tracking learning

Explanation: This question tests your ability to identify what a passage about organizational innovation is primarily concerned with. A correct answer must capture the passage's central argument about how innovation should be understood and managed, not just describe topics covered. The passage develops its main point by challenging the view of innovation as sudden inspiration from creative individuals, arguing instead that it depends on systems that make experimentation affordable and manageable. The author supports this by explaining how quick prototyping, sharing results, and learning from failures generate more usable ideas than waiting for breakthroughs, while acknowledging the need for clear criteria and resource allocation. Answer B correctly identifies this primary concern: explaining that innovation can be cultivated through structured experimentation and feedback systems, not merely through sporadic inspiration. Answer C is too vague and merely describes the topic without capturing the passage's specific argument about innovation as a managed process rather than rare inspiration.

Question 13

Read the passage and answer the question.

Economic inequality is frequently discussed as a single gap between "the rich" and "everyone else," but different forms of inequality can have different causes and consequences. Income inequality concerns flows of earnings over time, while wealth inequality concerns accumulated assets and debts. Because wealth can be passed across generations, wealth disparities may persist even when income gaps narrow. In addition, measures that reduce poverty—such as wage subsidies—may improve the bottom of the income distribution without substantially affecting concentration at the top. Conversely, policies that affect asset prices or inheritance rules may reshape wealth distribution while leaving wages largely unchanged. Treating inequality as a unitary phenomenon can therefore produce mismatched policy expectations: a reform designed to address one dimension may be criticized for failing to move another. A clearer debate begins by specifying which inequality is at issue and what mechanism is presumed to connect policy levers to distributional outcomes.

Which of the following best describes the main idea of the passage?

To argue that income inequality is the only meaningful form of inequality because it reflects current living standards
To provide a general discussion of inequality without distinguishing among different types
To explain that "inequality" includes distinct dimensions (income vs. wealth) and that policy debates should specify which is targeted (correct answer)
To present a detailed statistical analysis of how inheritance taxes affect national wealth shares over decades
To claim that all policies aimed at reducing inequality necessarily fail because markets always re-create disparities

Explanation: This question tests the main idea of the passage by seeking its best description. A correct answer should highlight the distinction between inequality types and the need for specificity in debates. The passage develops this by differentiating income and wealth, with examples of how policies affect each differently. It warns against treating inequality as unitary, which leads to mismatched expectations. Choice C captures the overall idea by emphasizing distinct dimensions and the call for precise policy discussions. In contrast, choice A is too narrow and absolute, claiming income is the only meaningful form, unlike the passage's balanced view. Choice E fails by being overly pessimistic, asserting policies always fail, which the passage does not claim.

Question 14

Passage: Some critics of consumer credit argue that borrowing for everyday purchases is irrational because it involves paying more than an item's sticker price. The passage responds that this critique overlooks the role of timing and uncertainty. For households with volatile income, access to credit can prevent costly disruptions—such as missed rent or utilities shutoffs—that may have larger long-term consequences than interest payments. However, the author also emphasizes that credit can amplify vulnerability when terms are opaque or when repayment depends on optimistic assumptions about future income. The passage therefore suggests evaluating credit not as inherently prudent or imprudent but as a tool whose value depends on contract design, borrower circumstances, and the availability of safer alternatives like emergency savings or social insurance.

Question: Which of the following best describes the main idea of the passage?

Credit card interest rates are too high and should be capped by law.
The passage explains why households with volatile income often miss rent payments.
Consumer credit can be either stabilizing or risky depending on context, so it should be assessed as a conditional tool rather than dismissed wholesale. (correct answer)
The passage is about borrowing for everyday purchases.
Borrowing is irrational because it always causes households to pay more than an item's sticker price.

Explanation: This question tests main idea identification, requiring recognition of the passage's central claim about consumer credit. A correct main idea answer must capture both the benefits and risks discussed while reflecting the author's nuanced position. The passage develops its central point by first presenting critics' view that borrowing for everyday purchases is irrational, then explaining how credit can prevent costly disruptions for households with volatile income. The author balances this by acknowledging risks when terms are opaque or assumptions are overly optimistic, ultimately arguing for conditional evaluation based on context. Choice C correctly captures this main idea by stating that consumer credit can be either stabilizing or risky depending on context and should be assessed conditionally. Choice D is too vague and fails to capture the nuanced argument, while choice E oversimplifies by claiming borrowing is always irrational, directly contradicting the passage's discussion of situations where credit prevents larger costs.

Question 15

Read the passage and answer the question.

In evaluating new technologies, policymakers often ask whether an innovation is "efficient," typically meaning that it reduces costs or increases output. The passage argues that this narrow framing can obscure a different question: efficient for whom and under what constraints. A tool that lowers production costs might simultaneously shift risks onto workers, concentrate market power, or increase environmental damage. In such cases, aggregate efficiency gains may coexist with losses that are substantial for particular groups.

The passage does not deny that efficiency matters; rather, it claims that efficiency is an incomplete criterion for public decision-making. Because many technological effects are distributed unevenly, evaluation should incorporate considerations of resilience, fairness, and accountability. For example, a highly optimized supply chain may minimize inventory costs but become fragile when disruptions occur; similarly, automated decision systems may speed administrative processes while making errors harder to contest. The passage concludes that technology assessment should treat efficiency as one value among several, not as a substitute for broader judgments about social outcomes.

Which of the following best describes the main idea of the passage?

argue that efficiency should be abandoned entirely as a standard for evaluating technology because it is inherently anti-democratic
compare optimized supply chains with automated decision systems in order to show that both always increase fragility
discuss technology policy and mention that efficiency, resilience, fairness, and accountability are relevant
argue that judging technology solely by efficiency is too narrow and that broader social criteria should also guide evaluation (correct answer)
explain how to calculate aggregate efficiency gains for a new technology using standardized economic metrics

Explanation: This question tests your ability to identify the main idea of a passage about technology evaluation. A correct main idea answer should encapsulate the central argument that unifies all parts of the passage, not just mention topics or provide partial coverage. The passage develops its central point by first critiquing the narrow focus on efficiency in technology evaluation, then arguing that this criterion alone obscures important distributional effects and other social considerations. The passage supports this argument with examples showing how efficiency gains can coexist with losses for particular groups, and concludes that multiple criteria including resilience, fairness, and accountability should guide evaluation. Answer D correctly captures this main idea by stating that judging technology solely by efficiency is too narrow and broader social criteria should also guide evaluation. Answer C fails because it merely mentions relevant topics without capturing the passage's specific argument about the inadequacy of efficiency as a sole criterion.

Question 16

Read the passage and answer the question.

In climate policy, carbon pricing is often presented as a single instrument that can replace most other interventions. By putting a cost on emissions, the argument goes, markets will find the cheapest reductions. Pricing can indeed encourage efficiency and innovation, but it does not automatically address every barrier to decarbonization. Some sectors face coordination problems—such as building charging networks—that require collective investment. Others involve long-lived infrastructure, where decisions made today lock in emissions for decades and where price signals may be too weak or too uncertain to shift behavior quickly. Additionally, political constraints can lead to prices that are lower than what models recommend, limiting impact. For these reasons, many analysts favor policy packages: carbon pricing combined with standards, public investment, and research support. The question is not whether pricing "works," but what complementary measures are needed for it to work at the scale and speed required.

Which of the following best describes the main idea of the passage?

To argue that carbon pricing is unnecessary because voluntary corporate action will solve climate change
To explain that while carbon pricing is useful, it is not sufficient by itself and should be part of a broader policy package (correct answer)
To provide a detailed comparison of different carbon tax rates used in various countries over time
To discuss climate policy in general without taking a position on carbon pricing
To claim that markets always reduce emissions optimally once any price is introduced, making other policies harmful

Explanation: This question tests the main idea of the passage by seeking its best description. A correct main idea answer should address the usefulness and limitations of pricing, advocating complements. The passage develops this by noting pricing's efficiency but barriers like coordination, with examples of sectors. It favors packages with standards and investments for scale. Choice B justifies this as the central idea, emphasizing insufficiency and broader policies. In contrast, choice A is a distractor that misrepresents by claiming pricing unnecessary, contradicting the passage's support. Choice E fails by overstating market optimality, ignoring the need for complements.

Question 17

Read the passage and answer the question.

Some proposals for improving democracy focus on increasing voter information, assuming that better-informed citizens will choose better leaders. While information matters, the assumption overlooks how political choices are made under time constraints and cognitive limits. Citizens often use shortcuts—party labels, endorsements, or perceived competence—because evaluating every policy claim is infeasible. These heuristics can be rational, but they can also be manipulated when signals are distorted by misinformation or by strategically ambiguous messaging. Therefore, reforms that merely provide more information may have limited effects if the information is not trusted, comprehensible, or connected to decision-making cues citizens actually use. Complementary reforms might include improving the reliability of signals (for example, through transparency about funding) and designing institutions that reduce the payoff to deception. Strengthening democracy, then, involves not only educating voters but also improving the informational environment and the incentives that shape political communication.

Which of the following best describes the main idea of the passage?

To argue that voter education is pointless because citizens never use information when voting
To explain that increasing voter information alone may be insufficient and that reforms should also address heuristics, trust, and incentives (correct answer)
To list several political parties and describe how their platforms differ on major issues
To provide a broad overview of democratic theory from ancient to modern times
To claim that endorsements are always accurate signals of candidate competence

Explanation: This question tests the main idea of the passage by seeking its best description. A correct main idea answer should highlight limitations of information and the need for broader reforms. The passage develops this by noting heuristics and manipulation, with examples like party labels. It suggests improving signals and incentives alongside education. Choice B justifies this as the central idea, addressing insufficiency and additional factors. For instance, choice A is too absolute, claiming education pointless, contradicting the passage's qualified support. Choice E fails by claiming endorsements always accurate, ignoring the passage's discussion of distortions.

Question 18

Read the passage and answer the question.

Conservation plans sometimes prioritize protecting large, contiguous wilderness areas on the assumption that bigger reserves always preserve more biodiversity. The passage argues that while size can matter, focusing exclusively on area can overlook how landscapes actually function. In fragmented regions, small habitats may serve as stepping-stones that allow species to move between larger patches, maintaining genetic diversity and enabling migration in response to climate shifts. In such cases, connectivity can be as important as total protected acreage.

The passage also notes that some species thrive in edge environments or depend on specific microhabitats that do not require vast tracts of land. Conversely, certain large reserves may be poorly located relative to future environmental change, offering less long-term protection than their size suggests. The passage concludes that conservation should be planned as a network problem: decision-makers should evaluate how protected sites interact, which corridors exist or can be restored, and which ecological processes are being supported. The goal is not to reject large reserves but to avoid a simplistic "bigger is always better" rule.

Which of the following best describes the main idea of the passage?

argue that conservation should consider connectivity and ecological function in addition to reserve size, rather than relying on a simple acreage rule (correct answer)
provide a detailed method for calculating the minimum corridor width required for different species to migrate
discuss conservation and mention that reserve size, stepping-stones, corridors, and microhabitats can matter
argue that small habitats are always superior to large wilderness reserves for preserving biodiversity
criticize conservation planners for deliberately ignoring climate change when they design large protected areas

Explanation: This question tests your ability to identify the main idea of a passage about conservation planning. A correct main idea answer should capture the central argument that the passage develops throughout, not just mention topics or provide incomplete coverage. The passage develops its central point by challenging the assumption that bigger reserves are always better for conservation, arguing instead that connectivity and ecological function matter as much as size. The author supports this by explaining how small habitats can serve as stepping-stones, how some species thrive in edge environments, and how conservation should be planned as a network problem. Answer A correctly captures this main idea by stating that conservation should consider connectivity and ecological function in addition to reserve size, rather than relying on a simple acreage rule. Answer C fails because it merely lists topics mentioned without capturing the passage's specific argument against the "bigger is always better" approach.

Question 19

Passage: Public discussions of automation often treat technology as an independent force that inevitably replaces human labor. The passage argues that this framing obscures the role of organizational choices. Whether a new system substitutes for workers or complements them depends on how tasks are redesigned, what training is provided, and which performance goals are prioritized. For instance, software that can draft routine reports might be used to reduce staff, but it might also be used to free staff to perform higher-value analysis—if the organization invests in developing those skills and adjusts incentives accordingly. The author acknowledges that some displacement is real, but contends that inevitability rhetoric can become self-fulfilling by discouraging experimentation with complementary designs. The passage's main point is that the impact of automation is shaped by decisions, not just by machines.

Question: The passage is primarily concerned with which of the following?

arguing that the consequences of automation depend heavily on organizational decisions about task design and training (correct answer)
providing a technical explanation of how modern software systems draft and summarize reports
discussing automation in the workplace
predicting that automation will eliminate most jobs within the next decade
describing how report-writing software can reduce staff in administrative departments

Explanation: This question tests primary purpose, asking what the passage is primarily concerned with addressing. A correct answer must capture the author's central argument about automation rather than just identifying the topic. The passage develops its argument by challenging the view of technology as an independent force, instead emphasizing how organizational choices shape whether automation replaces or complements workers. The author provides examples of how the same technology can have different impacts depending on task redesign, training, and performance goals. Choice A correctly identifies this primary concern by stating the author argues that automation's consequences depend on organizational decisions about task design and training. Choice C is too vague and merely states the general topic, while choice D misrepresents the passage by suggesting it predicts widespread job elimination, which contradicts the author's emphasis on organizational choice.

Question 20

Read the passage and answer the question.

Economic discussions of inflation sometimes imply that rising prices are driven by a single source, such as excessive consumer demand or increases in production costs. The passage argues that this either-or framing can mislead because inflation can reflect multiple mechanisms operating simultaneously. For example, a surge in demand may allow firms to raise prices, but those increases can be amplified if supply constraints limit output. Likewise, cost increases may begin in a particular sector yet spread if businesses and workers adjust expectations and incorporate anticipated inflation into contracts.

The passage emphasizes that identifying the dominant mechanism matters because policy tools differ in their effects. Measures that dampen demand may reduce price pressures but can also increase unemployment; policies that expand supply or reduce bottlenecks may take longer to implement. The passage does not offer a single policy prescription; instead, it urges analysts to treat inflation as a diagnosis problem in which the same symptom—rising prices—can have different underlying causes. Overconfidence in one-cause explanations, the passage concludes, encourages blunt policy responses that may miss the actual drivers.

The passage is primarily concerned with which of the following?

arguing that demand-reducing policies are always preferable to supply-side measures because they work faster
explaining why inflation should be analyzed as potentially multi-causal and why that diagnostic approach matters for choosing policy tools (correct answer)
describing the topic of inflation and listing several common economic indicators used to measure it
providing an exhaustive history of inflation episodes in multiple countries to demonstrate recurring patterns
criticizing economists for ignoring expectations in inflation models and insisting that expectations are the only true cause of inflation

Explanation: This question tests your ability to identify what a passage about inflation is primarily concerned with. A correct answer must capture the passage's central focus on how we should understand and analyze inflation, not just describe topics mentioned. The passage develops its main point by critiquing single-cause explanations of inflation and arguing that multiple mechanisms can operate simultaneously, making proper diagnosis crucial for policy selection. The author supports this by explaining how demand surges and supply constraints can interact, and how different policy tools have different effects depending on the underlying causes. Answer B correctly identifies this primary concern: explaining why inflation should be analyzed as potentially multi-causal and why that diagnostic approach matters for choosing policy tools. Answer C is too general and merely describes the topic without capturing the passage's specific argument about the importance of multi-causal analysis for policy decisions.
