Authors Main PointQuestion 1 of 20

In 2009, chef and writer Akiko Sato reflected in Broth and Memory: My grandmother insisted that miso soup should be made "by ear," meaning you listen for the simmer that never quite becomes a boil. At first I dismissed this as superstition, preferring thermometers and timers, but then I noticed that the same batch tasted harsher when I rushed it. The difference wasn't mystical: gentler heat kept the aromatics from turning bitter, and the tofu stayed intact instead of crumbling. I still measure when teaching beginners, yet I now understand the phrase as a lesson about attention, not about rejecting tools.

Which choice best states the main idea of the text?

Thermometers and timers are unreliable tools for teaching beginners to cook soup.

A traditional saying about cooking conveys the value of attentive technique.

Miso soup tastes harsher when aromatics turn bitter from excessive heat.

Tofu should be handled carefully so it does not crumble during simmering.

Question 1

Which choice best states the main idea of the text?

Thermometers and timers are unreliable tools for teaching beginners to cook soup.
A traditional saying about cooking conveys the value of attentive technique. (correct answer)
Miso soup tastes harsher when aromatics turn bitter from excessive heat.
Tofu should be handled carefully so it does not crumble during simmering.

Explanation: The main idea of the text is that a traditional saying about cooking miso soup conveys the value of attentive technique over reliance on tools. The passage introduces the grandmother's phrase 'by ear' and the narrator's initial dismissal using thermometers, then describes taste differences from gentle heat, leading to an understanding that the saying teaches attention without rejecting tools. This arc evolves from skepticism to appreciation, highlighting practical benefits like preventing bitterness. Choice A is tempting as it critiques thermometers and timers, which the narrator used but later contextualized, yet this misses the broader idea of the saying's wisdom. Choice C focuses on miso soup's harshness from excessive heat, a detail supporting the technique's importance but not the central message. A good strategy is to look for the author's reflective conclusion, which often distills the main idea beyond specific examples.

Question 2

In 2010, environmental policy analyst Noor Haddad wrote in Counting Carbon: A company announced it had become "carbon neutral" by purchasing offsets, and its ads showed forests and smiling farmers. Haddad notes that some offsets fund valuable projects, including efficient cookstoves that reduce smoke exposure. Yet she explains that neutrality claims can mislead when they obscure ongoing emissions from factories and shipping, especially if the offsets are difficult to verify or would have happened anyway. Haddad concludes that offsets may be useful as a supplement, but real accountability requires transparent reporting and direct emissions cuts.

Which choice best states the main idea of the text?

Carbon offsets are always unreliable because forest projects cannot be verified.
Offset-funded cookstoves can improve health by reducing indoor smoke exposure.
Neutrality claims based on offsets can obscure emissions, so direct cuts and transparency are needed. (correct answer)
Shipping emissions are the largest obstacle to corporate sustainability in most industries.

Explanation: The main idea of the text is that while carbon offsets can support good projects, neutrality claims may mislead without direct emissions cuts and transparency, as analyzed by Noor Haddad. The passage begins with a company's offset-based announcement and positive ads, acknowledges benefits like cookstoves, then critiques obscured emissions and verification issues, concluding that offsets are supplementary to accountable reductions. This flow contrasts marketing appeal with practical limitations, emphasizing balanced approaches. Choice B is tempting as it highlights cookstoves' health benefits, a positive example, but this supports rather than defines the main cautionary idea. Choice A overgeneralizes unreliability, which the text avoids. Ensure the main idea accounts for the author's qualifiers and conclusion, not isolated positives or negatives.

Question 3

In 2021, linguist Peter Cho wrote in Borrowed Words: Many people assume that when a language adopts foreign terms, it is "losing" its identity. Cho notes, however, that borrowed words often become tools for local creativity: speakers shorten them, shift their meanings, and attach native endings, producing forms that would sound strange in the source language. He offers the example of a loanword for "computer" that, in one community, also became a verb meaning "to organize a meeting efficiently." Purists may still dislike the trend, but the evidence suggests that borrowing can signal vitality, not decline, because it expands what speakers can do with their own grammar.

Which choice best states the main purpose of the text?

To argue that loanwords can reflect linguistic vitality by enabling new local uses. (correct answer)
To explain why purists dislike borrowed words and try to prevent their spread.
To describe how a community created a verb meaning "to organize a meeting efficiently."
To show that languages lose their identity when they adopt many foreign terms.

Explanation: The main purpose of the text is to argue that loanwords reflect linguistic vitality by enabling creative local adaptations, countering assumptions of identity loss. The passage introduces the common view of borrowing as decline, then provides examples of modifications like shifting meanings, leading to the conclusion that it expands grammatical possibilities. This arc challenges a belief with evidence, emphasizing creativity over purist concerns. Choice C is tempting because it details a specific verb example, which supports the argument but isn't the broader purpose. Choice D states languages lose identity with borrowings, directly opposing the text's point. A key strategy is to identify the author's counterargument, as it often defines the purpose against prevailing assumptions.

Question 4

In 2017, psychologist Erik Voss wrote in Memory's Housekeeping: People often try to strengthen memory by rereading notes, but Voss describes a study in which participants instead wrote down what they could recall, then compared their attempt to the original material. Rereaders felt more confident, which might suggest their method worked better. However, the recall-and-check group performed higher a week later, especially on questions requiring connections between ideas. Voss acknowledges that rereading can help with unfamiliar vocabulary, but he argues that the effort of retrieval is what reorganizes knowledge for long-term use.

Which choice best states the main purpose of the text?

To argue that practicing retrieval improves long‑term learning more than rereading notes does, (correct answer)
To explain why rereading notes increases students' confidence even when learning is weak,
To describe a study showing that unfamiliar vocabulary is best learned through rereading,
To claim that most memory strategies fail because people cannot accurately judge their knowledge,

Explanation: The main purpose of the text is to summarize Erik Voss's argument that retrieval practice enhances long-term learning more effectively than rereading, based on a study comparing the methods. The passage introduces rereading as a common strategy, describes the recall-and-check alternative in the study, notes rereaders' higher confidence, then reveals the retrieval group's superior performance on connected ideas, concluding with retrieval's reorganizing benefits despite rereading's niche uses. This arc contrasts intuitive appeal with evidence-based superiority, building to a recommendation for effortful methods. Choice B might attract because it explains confidence from rereading, a real finding, but this is a contrast point, not the purpose. Choice C tempts by mentioning rereading's help with vocabulary, yet the text positions this as secondary to the main argument. Remember, the purpose often lies in what the author 'argues,' unifying the study's setup and results.

Question 5

In 2022, computer scientist Leila Osman wrote in When Algorithms Listen: A music app promised "personalized discovery," and users assumed it simply matched songs to their tastes. Osman explains that the app's system also reacts to what it needs: it promotes tracks from labels that offer favorable licensing terms and repeats familiar artists to reduce the risk of users skipping. She notes that the algorithm still learns genuine preferences, and some listeners do find new genres through it. But Osman concludes that personalization is a negotiation between user desire and platform incentives, so recommendations reveal as much about business constraints as about individual taste.

Which choice best states the main idea of the text?

Music apps can help listeners discover new genres by learning their genuine preferences.
Personalized recommendations reflect both user tastes and platform incentives and constraints. (correct answer)
Licensing terms are the primary factor that determines which songs a music app promotes.
Users skip unfamiliar songs more often than familiar songs, so algorithms avoid novelty.

Explanation: The main idea of the text is that music app recommendations blend user preferences with platform business needs, so personalization reflects constraints as much as tastes, as explained by Leila Osman. The passage starts with users' assumption of pure taste-matching, details algorithmic influences like licensing and skip avoidance, notes genuine learning and discoveries, and concludes that recommendations negotiate desires and incentives. This structure uncovers layers behind apparent customization, contrasting user view with systemic realities. Choice A is tempting as it mentions discovering genres, a positive outcome, but this is balanced against business factors, not the sole idea. Choice C overemphasizes licensing as primary, which is one factor. In main idea questions, seek the nuanced claim that integrates pros and cons.

Question 6

In 2007, psychologist Dana Kline wrote in Remembering Together: In a lab study, pairs of friends watched a short film and then recalled it either separately or as a duo. The duo condition produced fewer total details, which might suggest that collaboration harms memory. But when the same participants returned a week later, those who had recalled together were more consistent, repeating fewer invented or distorted elements. Kline argues that joint remembering functions less like a search for maximum information and more like a filter: friends prune each other's guesses, sometimes at the cost of breadth, to preserve accuracy over time.

Which choice best states the main idea of the text?

Recalling a film with a friend can reduce details but improve long‑term accuracy. (correct answer)
Pairs of friends recall films more slowly than individuals recalling separately.
A week-long delay makes participants more likely to invent details about a film.
Collaboration in memory tasks generally harms recall and should be avoided.

Explanation: The main idea of the text is that collaborative recall with friends can reduce immediate details but improve long-term accuracy by filtering distortions. The passage describes a study comparing solo and duo recall, notes fewer details in duos initially, but highlights greater consistency later, concluding that joint remembering acts as a filter. This arc presents findings, then interprets them to reframe collaboration's value over time. Choice C might attract because it mentions inventing details after a delay, but this applies to solo recall implicitly, not the main idea. Choice D generalizes harm from collaboration, contradicting the text's positive reframing. In main idea questions, look beyond surface results to the author's explanatory conclusion.

Question 7

In 2004, political scientist Omar Feld wrote in Debate as Theater: Commentators praised a televised debate for its "substance," citing the candidates' detailed statistics about jobs and taxes. Feld does not deny that numbers were offered, and he lists several, including a precise unemployment figure repeated by both sides. But he shows that the debate's format encouraged rehearsed zingers: strict time limits punished explanation, and the studio audience rewarded confident interruption. Polls afterward suggested viewers remembered tone more than policy. Feld concludes that calling such events substantive can confuse the presence of data with genuine deliberation.

Which choice best states the main idea of the text?

Televised debates can appear substantive while their format discourages genuine deliberation. (correct answer)
Unemployment statistics are often repeated by candidates because voters demand precise numbers.
Studio audiences should be removed from debates because they reward interruption and zingers.
Viewers remembered debate tone more than policy because polls are influenced by media coverage.

Explanation: The main idea of the text is that televised debates can seem substantive due to data but their format promotes theater over deliberation, as critiqued by Omar Feld. The passage praises a debate's job statistics, lists examples, then analyzes how time limits and audience favored zingers, noting polls on tone over policy, and concludes against confusing data with depth. This structure peels back apparent substance to reveal performative flaws. Choice B is tempting as it mentions repeated unemployment stats, a detail, but this illustrates the format issue, not the idea. Choice C suggests removing audiences, implied but not the core. In main idea questions, seek the author's warning about misperceptions in the conclusion.

Question 8

In 2005, art conservator Nadia Petrov wrote in The Color Beneath: When a museum cleaned a nineteenth-century portrait, viewers were shocked by the bright blue ribbon that emerged from beneath the varnish. Some claimed the conservators had "changed" the painting, while others insisted the artist must have intended the muted brown that generations had known. Petrov explains that the controversy confuses aging with authorship: varnish yellows, pigments shift, and what looks "authentic" may be simply familiar. She concedes that restoration involves choices, such as how far to remove later layers, but she argues that refusing to intervene is also a choice—one that can freeze an accident of chemistry into a false tradition.

Which choice best states the main idea of the text?

A bright blue ribbon proves the portrait was originally more colorful than viewers assumed.
Restoration debates often hinge on mistaking chemical aging for artistic intent. (correct answer)
Conservators should always remove all later layers to reveal the original paint.
Museums create controversy when they clean paintings that the public recognizes.

Explanation: The main idea of the text is that restoration debates often confuse chemical aging with artistic intent, as in a portrait's cleaned ribbon sparking controversy. The passage describes shock at the bright color, claims of change versus intent, explains aging processes, and argues refusal to restore freezes accidents. This arc presents a case, then generalizes to choices in conservation. Choice A focuses on the ribbon proving original colorfulness, a detail but not the broader idea of mistaking aging. Choice C advocates always removing layers, which the text presents as one choice among options. A strategy is to distinguish examples from the overarching principle they illustrate.

Question 9

In 2013, astronomer Caleb Nguyen wrote in Small Telescopes, Big Claims: Amateur skywatchers often report "new stars," and professional astronomers sometimes dismiss these sightings as wishful thinking. Yet a recent collaboration showed that the amateurs' strength is not precision but persistence: they scan the same patch of sky night after night, noticing subtle changes that automated surveys may miss during bad weather or maintenance. The project still relied on professional instruments to confirm a supernova candidate, and it trained volunteers to avoid common errors like confusing satellites for transients. Even so, the partnership demonstrates that scientific discovery can depend on organized patience as much as on expensive equipment.

Which choice best states the main purpose of the text?

To argue that amateurs can aid discovery when their persistence is coordinated with verification. (correct answer)
To explain why automated sky surveys are usually more accurate than human observers.
To describe the training volunteers need to avoid mistaking satellites for transients.
To criticize professionals for dismissing reports of new stars as wishful thinking.

Explanation: The main purpose of the text is to argue that amateurs can aid astronomical discovery through persistence when coordinated with professional verification. The passage begins by noting dismissals of amateur reports, then highlights their strength in consistent monitoring, describes a collaboration confirming a supernova, and concludes that organized patience complements equipment. This arc shifts from skepticism to demonstration of value, emphasizing partnership. Choice D might seem appealing because it mentions criticizing professionals for dismissing reports, but this is introductory and not the main purpose, which focuses on successful collaboration. Choice B explains automated surveys' accuracy, a contrast but not the core argument. In purpose questions, identify the author's thesis, often in the final sentence, to capture what the text seeks to establish overall.

Question 10

In 2003, marine scientist Jorge Ibarra wrote in Quiet Reefs: Divers once assumed that reef fish relied mainly on sight to find shelter, since the water is clear in many lagoons. Ibarra describes an experiment in which juvenile fish were released near artificial reefs while recordings of healthy reef "crackling" played from underwater speakers. The fish swam toward the sound even when the structures were out of view, though they still used sight to choose among crevices once they arrived. Ibarra argues that conservation plans should consider soundscapes: if boat noise masks reef crackle, young fish may fail to locate habitats even when the coral remains.

Which choice best states the main idea of the text?

Juvenile reef fish use reef sounds to locate habitat, so noise can hinder conservation. (correct answer)
Artificial reefs provide better shelter than natural reefs because they have more crevices.
Clear lagoon water allows divers to observe how fish choose crevices by sight.
Underwater speakers are the most reliable method for increasing fish populations near reefs.

Explanation: The main idea of the text is that juvenile reef fish use sound to locate habitats, so conservation must address noise pollution to prevent disruption, as argued by marine scientist Jorge Ibarra. The passage begins with the assumption that fish rely on sight in clear water, describes an experiment showing attraction to reef sounds even without visibility, notes sight's role in final choices, and concludes with implications for soundscapes amid boat noise. This arc challenges visual dominance with auditory evidence, leading to a conservation payoff. Choice C may tempt because it mentions clear water enabling visual observation, a setup detail, but the text uses this to contrast with the surprising sound reliance, not as the main idea. In main idea questions, ensure the choice captures the author's argument or implication, not just background assumptions.

Question 11

In 2019, psychologist Maren Okafor summarized survey research in Attention Economies: participants reported their daily phone use and also completed a task measuring how quickly they recovered focus after interruptions. Okafor notes a tempting interpretation—heavy use must cause poor attention—but points out that the strongest pattern ran the other way: people who already struggled to regain focus were more likely to check their phones frequently, perhaps seeking brief relief from frustration. She adds that design features like notifications still matter, yet she argues that effective interventions must address underlying attentional difficulty rather than blaming devices alone.

Which choice best states the main idea of the text?

Phone notifications are the single most important cause of attention problems in adults.
Survey tasks cannot accurately measure how quickly people recover focus after interruptions.
Frequent phone checking may reflect preexisting attention struggles, complicating simple cause claims. (correct answer)
People check their phones mainly to seek relief from frustration during difficult workdays.

Explanation: The main idea of the text is that frequent phone checking may stem from preexisting attention struggles, which complicates claims that phone use solely causes poor focus. The passage summarizes the survey linking phone use to attention recovery, cautions against assuming causation from heavy use, points out the reverse pattern where attention issues predict more checking, and concludes that interventions should address underlying difficulties alongside device features. Choice A appears tempting because it references phone notifications and attention problems, which are discussed, but it asserts notifications as the single cause, contradicting the text's emphasis on bidirectional influences and nuance. Test-taking strategy: Beware of choices that simplify correlations into one-way causation, especially when the passage explicitly qualifies or reverses the intuitive interpretation.

Question 12

In 2018, journalist Priya Nandakumar wrote in her essay collection Small Inventions: "A city's 'smart' traffic lights were sold as a solution to congestion, and early reports did show shorter waits on two downtown corridors. Yet the city's own audit found the bigger change elsewhere: the lights produced detailed timing data that allowed engineers to redesign bus routes, reducing missed transfers and making ridership more predictable. The system also revealed an unexpected inequity—some neighborhoods endured longer pedestrian cycles—prompting a recalibration. The lights, then, mattered less as an automated fix than as a tool that exposed patterns humans could act on."

Which choice best states the main idea of the text?

Smart traffic lights initially reduced downtown congestion on two major corridors.
Data from smart traffic lights enabled broader transit improvements and equity adjustments. (correct answer)
Cities should replace human planners with automated systems to manage transportation.
Pedestrian signal timing is the most important factor in public transit ridership.

Explanation: The main idea of the text is that while smart traffic lights were intended to reduce congestion directly, their greater value came from providing data that enabled broader transportation improvements and equity adjustments. The passage begins by noting the initial promise and modest success in reducing waits on specific corridors, then shifts to reveal the audit's findings about data-driven changes like bus route redesigns and pedestrian cycle recalibrations, ultimately emphasizing the lights' role as a tool for human-led enhancements rather than an automated solution. Choice A is tempting because it mentions the early reports of reduced congestion on downtown corridors, which are real details from the text, but it focuses only on the initial, limited outcome and misses the broader impact highlighted in the audit and the conclusion. In main idea questions, always ensure the chosen answer captures the passage's overall emphasis, not just an introductory or partial element.

Question 13

In 1904, essayist Lillian Moore wrote in On Public Benches: The city installed ornate benches to "encourage civic fellowship," and the mayor's dedication speech promised strangers would become neighbors. For a month, the benches were indeed occupied: children climbed them, couples lingered, and old men argued about baseball. Then the parks department added signs listing prohibited behaviors in dense, anxious language, and a police officer began circling the square at dusk. The benches remained, but people sat more briefly and looked over their shoulders, as if the wood itself had become accusatory. Moore concludes that design can invite community only when governance does not simultaneously communicate suspicion.

Which choice best states the main purpose of the text?

To argue that civic design succeeds only when rules and enforcement do not undermine trust. (correct answer)
To describe how ornate benches can beautify a city square and attract visitors.
To explain why dense signage is necessary to prevent prohibited park behaviors.
To illustrate that baseball debates are the most common form of public fellowship.

Explanation: The main purpose of the text is to argue that civic design succeeds in fostering community only when rules and enforcement avoid undermining trust. The passage describes benches installed for fellowship, initial positive use, then signs and policing causing wariness, leading to the conclusion that governance must align with invitation. This arc builds from promise to unintended consequence, illustrating suspicion's impact. Choice B seems relevant as it mentions ornate benches attracting visitors, but this is introductory and not the purpose, which critiques the full context. Choice C advocates dense signage, opposing the text's point. In purpose questions, the author's moral or lesson, often in the conclusion, reveals the intent.

Question 14

In 2021, materials scientist L. Chen wrote in Practical Polymers: A lab developed a biodegradable packaging film that resisted tearing in dry air but weakened in humid warehouses. Chen first describes the team's initial fix—adding more cross-linking—which improved strength yet made the film too stiff for automated sealing machines. Next, Chen reports a second approach: mixing in a small amount of plant wax, which did little for dry strength but stabilized performance across humidity levels. Chen concludes that the project's lesson is not that one additive is "best," but that designers must decide which failure is acceptable in the real supply chain.

Which choice best describes the overall structure of the text?

It introduces a problem, then compares two attempted fixes before drawing a broader lesson. (correct answer)
It recounts an invention's history, then profiles the scientists who funded it.
It argues for banning plastic packaging, then lists alternatives already available.
It defines key chemistry terms, then tests readers with practice questions.

Explanation: The text structure introduces a problem (packaging film failing in humidity), compares two attempted solutions, then draws a broader lesson about design trade-offs. First, Chen describes the initial fix of adding cross-linking, which improved strength but created a new problem (too stiff for machines). Then, Chen presents the second approach using plant wax, which didn't improve dry strength but stabilized performance across conditions. The passage concludes with a lesson about accepting certain failures in real-world applications rather than seeking perfection. Choice B incorrectly focuses on invention history and scientists, Choice C advocates for banning plastic (not mentioned), and Choice D suggests a quiz format that doesn't exist. Structure questions require recognizing the problem-solution-lesson pattern common in technical writing.

Question 15

In 1974, biographer K. N. Shah wrote in Workshop of a Composer: As a student, composer Ilya Petrov copied entire symphonies by hand, an exercise his classmates mocked as pointless drudgery. Shah admits the copying did not make Petrov instantly original, and Petrov's early pieces even resemble the composers he transcribed. Yet Shah shows how the practice trained Petrov's ear for structure: he began predicting modulations before they arrived and noticing how themes returned in altered form. When Petrov later wrote his own celebrated quartet, Shah argues, its daring rests on habits learned through imitation rather than on sudden inspiration.

Which choice best states the main idea of the text?

Petrov's classmates were wrong to mock him for copying symphonies by hand.
Petrov's early compositions closely resembled the works he transcribed as a student.
A composer's originality can grow from disciplined imitation that develops structural awareness. (correct answer)
Petrov's celebrated quartet succeeded because it used daring modulations and returning themes.

Explanation: The main idea of the text is that composer Ilya Petrov's originality developed from disciplined imitation through transcription, which built his structural awareness, as argued by biographer K. N. Shah. The passage starts with Petrov's mocked student practice of copying symphonies, admits initial resemblances in his work, then explains how it honed his predictive skills for modulations and themes, leading to Shah's conclusion that this foundation enabled his celebrated quartet. This flow contrasts early dismissal with later recognition of imitation's value, building to the payoff of creative growth. Choice B is tempting as it notes the resemblance of Petrov's early pieces to transcribed works, a mentioned fact, but this is transitional, not the core idea of imitation fostering originality. Choice D focuses on specific quartet elements like modulations, which illustrate but do not encapsulate the broader claim. A key strategy is to seek the idea that unifies the passage's progression from challenge to achievement.

Question 16

In 2009, cultural critic Dev Patel wrote in The Myth of the "Natural" Voice: A singing competition advertised that it rewarded "raw talent," implying that training dilutes authenticity. Patel follows one finalist who is praised for sounding effortless, then reveals the hidden labor: daily scales, careful hydration, and a coach who adjusts vowel shapes to protect the singer's range. Patel notes that stage lighting and microphone choices also shape what audiences perceive as "natural." He concludes that calling a voice untrained often erases the work and technology behind it, turning craft into a romantic story of innate gift.

Which choice best states the main purpose of the text?

To argue that the idea of a "natural" singing voice often hides training and technology, (correct answer)
To explain how vowel-shape coaching can protect a singer's range during competitions,
To describe why audiences prefer finalists who appear effortless on stage,
To claim that singing competitions should ban microphones and stage lighting to ensure fairness,

Explanation: The main purpose of the text is to present Dev Patel's argument that the notion of a 'natural' singing voice often conceals underlying training and technology, critiquing a competition's emphasis on raw talent. The passage introduces the competition's anti-training rhetoric, details a finalist's hidden efforts like scales and coaching, notes stage elements shaping perception, and concludes that praising untrained voices erases craft in favor of romantic myths. This arc exposes labor behind apparent effortlessness, building to a cultural critique. Choice C may tempt because it mentions audience preference for effortless performers, a noted perception, but this illustrates the myth rather than the purpose. Choice B focuses on vowel coaching, a supporting example, not the core. A strategy is to identify what the author 'concludes' about a concept, as it captures the purpose beyond examples.

Question 17

In 2006, historian Miguel Aranda argued in Harbors of Paper that a port's archives can mislead readers about what mattered most in daily trade. He notes that officials preserved customs ledgers with obsessive care, so modern scholars can tally duties by the penny; meanwhile, sailors' informal credit notes—used to buy food, rope, and repairs—were tossed out as clutter. Aranda describes one rare cache of such notes that survived only because it was stuffed into a shipowner's desk, and it shows how often voyages depended on small, personal loans. He concludes that what survives in an archive often reflects bureaucracy's habits more than commerce's realities.

Which choice best states the main purpose of the text?

To argue that preserved records can distort historians' understanding of everyday trade. (correct answer)
To explain how customs ledgers allowed officials to calculate duties with precision.
To describe the discovery of a shipowner's desk filled with sailors' credit notes.
To praise bureaucratic recordkeeping as the most reliable guide to port commerce.

Explanation: The main purpose of the text is to argue that preserved records like customs ledgers can distort historians' understanding of everyday trade by prioritizing bureaucratic details over informal practices. The passage starts by introducing Aranda's argument about misleading archives, provides examples of preserved ledgers versus discarded credit notes, describes a rare surviving cache to illustrate overlooked aspects of commerce, and concludes that archives reflect bureaucracy more than reality. Choice B might seem appealing because it references the precision of duties in ledgers, which is mentioned in the text, but it misrepresents the purpose by suggesting the text explains this positively, whereas the overall arc critiques such records for creating a skewed view. For purpose questions, identify the author's intent by tracing how evidence builds to a central claim, rather than isolating supportive details.

Question 18

In 2015, economist Tarek Mahmoud reported in Work and Worth on a field experiment at a call center: half the new hires were told their work primarily helped customers solve urgent problems, while the other half heard a standard orientation about efficiency metrics. Both groups received identical training and pay. After three months, the "customer-impact" group had slightly longer calls but fewer repeat complaints and lower turnover. Mahmoud cautions that the intervention wasn't a cure-all—some employees still burned out during peak season—but he argues it shows how reframing a job's meaning can change performance in measurable ways.

Which choice best states the main purpose of the text?

To argue that emphasizing a job's social impact can improve retention and service outcomes. (correct answer)
To explain why call centers should reduce training time and increase efficiency metrics.
To describe how peak-season demand inevitably causes burnout among call-center employees.
To claim that longer calls always lead to more customer complaints and higher turnover.

Explanation: The main purpose of the text is to argue that emphasizing a job's social impact, such as helping customers, can improve employee retention and service outcomes in settings like call centers. The passage introduces the experiment's setup with two groups receiving different orientations, reports the results showing better performance in the impact-focused group, acknowledges limitations like seasonal burnout, and concludes by advocating for reframing job meaning to influence behavior. Choice D is a tempting distractor because it mentions longer calls, which occurred in the experiment, but it incorrectly generalizes this as always leading to more complaints and turnover, missing the positive outcomes and the text's qualified endorsement. In purpose questions, distinguish the author's balanced argument from extreme or reversed interpretations of evidence presented.

Question 19

In 2006, historian Rafael Ortiz wrote in Letters from the Wharf: When the harbor strike ended, newspapers celebrated the return of commerce, but Ortiz follows a dockworker named Lena who kept a diary during the stoppage. At first her entries describe missed wages and the shame of borrowing coal, details that could make the strike seem only destructive. Yet as the weeks pass, Lena records neighbors sharing meals and teaching each other bookkeeping so they could challenge unfair pay slips. Ortiz ends by suggesting that the strike's most lasting effect was not the halted ships but the new habits of cooperation that outlived the dispute.

Which choice best states the main idea of the text?

A dockworker's diary shows how a strike fostered enduring community cooperation. (correct answer)
Newspapers misrepresented the harbor strike by focusing only on economic losses.
Borrowing coal and missing wages made the harbor strike especially painful.
Bookkeeping lessons helped dockworkers correct unfair pay slips after the strike.

Explanation: The main idea of the text is that the harbor strike's lasting impact was the fostering of community cooperation, as revealed through a dockworker's diary, rather than just economic disruption. The passage starts with newspapers' focus on commerce resuming, then shifts to Ortiz's analysis of Lena's diary, which evolves from descriptions of hardship to accounts of shared meals and skill-building, leading to Ortiz's conclusion about enduring habits of cooperation. This arc contrasts superficial views of the strike as destructive with deeper social benefits that persisted. Choice C could be tempting as it details the painful aspects like borrowing coal and missed wages mentioned in the diary, but these are initial setup points that highlight the contrast to the positive outcomes, not the main idea. Beware that in main idea questions, distractors often zoom in on vivid details from the passage's beginning while ignoring the author's concluding emphasis on transformation.

Question 20

In 2016, architect Salma Idris wrote in Stairs That Invite: A library renovation added a grand staircase in the lobby, and donors praised it as a sculptural centerpiece. Idris observes that the stairs did become a popular meeting spot, but she also notes who did not use them: patrons with strollers, those with limited mobility, and anyone carrying stacks of books. The building technically met accessibility codes through an elevator tucked behind a service door, yet many visitors reported feeling as if they were "taking the back way." Idris concludes that inclusive design is not only about providing access, but about making the accessible route equally visible and welcoming.

Which choice best states the main purpose of the text?

To argue that accessibility requires welcoming, visible routes rather than hidden code-compliant ones, (correct answer)
To describe how donors influenced the library renovation by funding a sculptural staircase,
To explain why elevators are less efficient than stairs for moving patrons through a library lobby,
To claim that meeting accessibility codes is sufficient to ensure all patrons feel included,

Explanation: The main purpose of the text is to present Salma Idris's argument that true accessibility in design means making compliant routes visible and welcoming, not just hidden options, using a library renovation as an example. The passage describes the praised staircase, notes its exclusion of certain patrons, contrasts with the tucked elevator causing feelings of marginalization, and concludes that inclusion requires equal prominence. This arc critiques aesthetic priorities, advocating integrated access. Choice B tempts by mentioning donor influence on the staircase, a detail, but this sets up the problem, not the purpose. Choice D claims codes suffice, directly opposed by the text. Focus on the author's call for what 'inclusive design is not only about' to capture the purpose.
