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

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?

  1. Thermometers and timers are unreliable tools for teaching beginners to cook soup.
  2. A traditional saying about cooking conveys the value of attentive technique. (correct answer)
  3. Miso soup tastes harsher when aromatics turn bitter from excessive heat.
  4. 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 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?

  1. To argue that civic design succeeds only when rules and enforcement do not undermine trust. (correct answer)
  2. To describe how ornate benches can beautify a city square and attract visitors.
  3. To explain why dense signage is necessary to prevent prohibited park behaviors.
  4. 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 3

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?

  1. It introduces a problem, then compares two attempted fixes before drawing a broader lesson. (correct answer)
  2. It recounts an invention's history, then profiles the scientists who funded it.
  3. It argues for banning plastic packaging, then lists alternatives already available.
  4. 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 4

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?

  1. Carbon offsets are always unreliable because forest projects cannot be verified.
  2. Offset-funded cookstoves can improve health by reducing indoor smoke exposure.
  3. Neutrality claims based on offsets can obscure emissions, so direct cuts and transparency are needed. (correct answer)
  4. 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 5

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?

  1. Petrov's classmates were wrong to mock him for copying symphonies by hand.
  2. Petrov's early compositions closely resembled the works he transcribed as a student.
  3. A composer's originality can grow from disciplined imitation that develops structural awareness. (correct answer)
  4. 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 6

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?

  1. To argue that the idea of a "natural" singing voice often hides training and technology, (correct answer)
  2. To explain how vowel-shape coaching can protect a singer's range during competitions,
  3. To describe why audiences prefer finalists who appear effortless on stage,
  4. 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 7

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?

  1. Phone notifications are the single most important cause of attention problems in adults.
  2. Survey tasks cannot accurately measure how quickly people recover focus after interruptions.
  3. Frequent phone checking may reflect preexisting attention struggles, complicating simple cause claims. (correct answer)
  4. 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 8

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?

  1. To argue that practicing retrieval improves long‑term learning more than rereading notes does, (correct answer)
  2. To explain why rereading notes increases students' confidence even when learning is weak,
  3. To describe a study showing that unfamiliar vocabulary is best learned through rereading,
  4. 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 9

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?

  1. To argue that preserved records can distort historians' understanding of everyday trade. (correct answer)
  2. To explain how customs ledgers allowed officials to calculate duties with precision.
  3. To describe the discovery of a shipowner's desk filled with sailors' credit notes.
  4. 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 10

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?

  1. To argue that emphasizing a job's social impact can improve retention and service outcomes. (correct answer)
  2. To explain why call centers should reduce training time and increase efficiency metrics.
  3. To describe how peak-season demand inevitably causes burnout among call-center employees.
  4. 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 11

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?

  1. A dockworker's diary shows how a strike fostered enduring community cooperation. (correct answer)
  2. Newspapers misrepresented the harbor strike by focusing only on economic losses.
  3. Borrowing coal and missing wages made the harbor strike especially painful.
  4. 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 12

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?

  1. To argue that accessibility requires welcoming, visible routes rather than hidden code-compliant ones, (correct answer)
  2. To describe how donors influenced the library renovation by funding a sculptural staircase,
  3. To explain why elevators are less efficient than stairs for moving patrons through a library lobby,
  4. 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.

Question 13

In 2023, marine biologist Tessa Liu wrote in Reefs in the Shade: A team tested whether artificial shade cloth could help corals survive heat waves. In the first month, shaded plots retained more living tissue, which sparked headlines about a "simple fix." But by the third month, algae growth increased under the cloth, reducing water flow and offsetting some gains, while unshaded plots that had partially bleached began recovering as temperatures fell. Liu concludes that shade can be a useful emergency tool, yet its effects depend on timing and local conditions, and it cannot substitute for reducing the warming that makes such interventions necessary.

Which choice best states the main idea of the text?

  1. Shade cloth is a simple fix that reliably prevents coral bleaching during heat waves.
  2. Shading corals can help temporarily but has trade-offs and cannot replace addressing warming. (correct answer)
  3. Algae growth under shade cloth always reduces water flow enough to kill corals.
  4. Unshaded corals recover fully once temperatures fall, making interventions unnecessary.

Explanation: The main idea of the text is that shading corals offers temporary help during heat waves but involves trade-offs and cannot replace addressing ocean warming. The passage details a shade cloth test's initial success, later algae issues and recovery in unshaded areas, concluding it's a tool with limits. This arc presents promising results, then nuances with complications, emphasizing broader needs. Choice A seems positive as it calls shade a reliable fix, but the text highlights its temporary, conditional nature. Choice C overstates algae always killing corals, a risk not absolute. A strategy is to note time-based progression, as it reveals caveats to initial findings.

Question 14

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?

  1. Televised debates can appear substantive while their format discourages genuine deliberation. (correct answer)
  2. Unemployment statistics are often repeated by candidates because voters demand precise numbers.
  3. Studio audiences should be removed from debates because they reward interruption and zingers.
  4. 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 15

In 1962, botanist Elise Grant wrote in Seeds on the Wind: A colleague insisted that a certain alpine plant could not spread beyond a single valley because its seeds were heavy. Grant climbed neighboring ridges and found the plant in scattered pockets, a discovery that could be dismissed as accidental human transport. But she then observed ants dragging the seeds into their nests, where some later sprouted in nutrient-rich refuse piles. Grant concedes that wind dispersal is limited for this species, yet she argues that small animal partners can expand a plant's range in ways that simple weight-based assumptions overlook.

Which choice best states the main idea of the text?

  1. Ants can disperse heavy seeds, challenging assumptions about a plant's limited range. (correct answer)
  2. Alpine plants often spread to neighboring ridges through accidental human transport.
  3. Wind dispersal is ineffective for many mountain species because their seeds are heavy.
  4. Nutrient-rich refuse piles provide ideal conditions for seed sprouting in ant nests.

Explanation: The main idea of the text is that ants can disperse heavy seeds, expanding a plant's range beyond what weight-based assumptions predict, as discovered by botanist Elise Grant. The passage starts with a colleague's claim limiting the plant to one valley due to seed weight, describes Grant's findings on neighboring ridges and ant observations, notes possible human transport but emphasizes ant nests' role, and concludes that animal partners challenge simple dispersal models. This structure builds from skepticism to evidence of overlooked mechanisms, with wind's limitations as setup. Choice C is tempting as it states wind's ineffectiveness for heavy seeds, a conceded point, but this supports rather than defines the main idea of alternative dispersal. In main idea questions, look for the discovery or argument that reframes initial assumptions.

Question 16

In 2019, economist R. Ahmed summarized a study in Markets & Memory: A city replaced paper bus tickets with a tap card, expecting faster boarding. The first month did cut average stop time, but the researchers noticed an unexpected shift: riders began taking slightly longer routes with fewer transfers, even when the shortest route remained cheaper. Interviews suggested that once the card removed the visible "cost" of each transfer, riders started optimizing for mental effort rather than minutes. Ahmed adds that the tap system also reduced fare disputes, yet he emphasizes that the largest change was psychological: pricing felt less like a sequence and more like a single decision.

Which choice best states the main purpose of the text?

  1. To argue that tap cards should replace paper tickets in every transit system.
  2. To explain how a payment change altered riders' route choices by shifting perceived costs. (correct answer)
  3. To describe how faster boarding times reduced crowding at the busiest bus stops.
  4. To show that eliminating fare disputes was the most important benefit of tap cards.

Explanation: The passage's main purpose is to explain how switching to tap cards changed riders' route choices by altering their perception of costs. While the city expected only faster boarding, Ahmed's study revealed a psychological shift: riders began taking longer routes with fewer transfers because the tap card made the "cost" of transfers invisible, leading them to optimize for mental effort over time. The text mentions faster boarding and reduced fare disputes, but these are presented as secondary effects—Ahmed emphasizes that the largest change was psychological, transforming how riders perceived the pricing structure. Choice A advocates for universal adoption (not the text's purpose), while Choices C and D focus on minor benefits rather than the central behavioral insight. Main idea questions often test whether you can identify the unexpected finding that the author emphasizes most.

Question 17

In 2016, sociolinguist Priya Nand wrote in Voices at the Counter: A coffee chain trained baristas to repeat customers' orders "verbatim" to reduce mistakes. Nand begins by describing the training script and the company's expectation that exact repetition signals respect. She then presents recordings showing that baristas who made small, polite adjustments—adding "please," smoothing grammar, or using the customer's name—actually received fewer complaints, even when the drink was wrong. Nand ends by arguing that what customers hear as respect is not literal accuracy but social alignment, and that rigid scripts can sound mocking when they ignore everyday conversational norms.

Which choice best describes the overall structure of the text?

  1. It presents a policy goal, then uses evidence to argue the policy misjudged what matters. (correct answer)
  2. It defines key linguistic terms, then surveys how often each term appears in speech.
  3. It compares two coffee chains, then concludes that both should raise prices.
  4. It narrates a customer dispute, then advises baristas to avoid speaking at all.

Explanation: The text structure presents a policy goal (verbatim repetition for accuracy and respect), then uses evidence to argue the policy misjudged what actually matters to customers. Nand begins with the company's training expectations, then presents recordings showing that baristas who made polite adjustments received fewer complaints despite occasional errors. This evidence supports her conclusion that customers value social alignment over literal accuracy, and rigid scripts can backfire by ignoring conversational norms. Choice B incorrectly suggests defining linguistic terms, Choice C invents a comparison between chains, and Choice D mischaracterizes the narrative and advice. When analyzing structure, look for how evidence is used to challenge initial assumptions.

Question 18

In 1893, novelist Edwin Harrow wrote in The Brass Lantern: I used to admire the lighthouse keeper for his solitude, imagining it as a kind of freedom. Then I watched him tally the oil, scrub the lenses, and copy weather notes into a ledger that no one in town would ever read. When a storm finally arrived, it was not his bravery that impressed me but his routine; the lamp held because he had treated every calm evening as rehearsal. The sea, of course, remained indifferent, and the townspeople still told heroic stories afterward. Yet the real safeguard was the keeper's unglamorous attention to repetition.

Which choice best states the main purpose of the text?

  1. To argue that routine, rather than heroism, is what makes the lighthouse dependable. (correct answer)
  2. To describe how townspeople turn storms into heroic stories for entertainment.
  3. To explain why the sea's indifference makes human bravery seem insignificant.
  4. To illustrate how a lighthouse keeper's solitude can feel like personal freedom.

Explanation: The main purpose of the text is to argue that the lighthouse's dependability stems from the keeper's routine attention rather than heroic acts during storms. The passage opens with the narrator's initial admiration for the keeper's solitude, then shifts to observations of daily tasks like tallying oil and scrubbing lenses, culminating in the realization that routine prepared for storms more effectively than bravery. This arc contrasts romanticized views with the unglamorous reality, emphasizing repetition as the true safeguard. Choice B is a tempting distractor because it references townspeople turning storms into heroic stories, which appears in the text, but this is a minor detail illustrating indifference rather than the main purpose. Choice C mentions the sea's indifference making bravery insignificant, a supporting idea that doesn't fully address the focus on routine's value. A key strategy is to distinguish purpose by asking what the author aims to persuade readers about, often revealed in the concluding sentence.

Question 19

In 1887, travel writer Henri Leclerc wrote in Notes from the Northern Line: The new railway promised to "unite the provinces," and investors spoke as if steel alone could dissolve old rivalries. On my journey, I did see markets swell as farmers shipped cheese farther than before, and I watched children chase the train as if it were a festival. Yet in the dining car, passengers still sorted themselves by dialect, and stationmasters announced arrivals in the dominant tongue, leaving some travelers to guess. The railway connected towns geographically, but it also revealed how connection can magnify differences by placing them in constant proximity.

Which choice best states the main idea of the text?

  1. The railway increased trade and entertainment by enabling farmers and children to engage with it.
  2. Investors were wrong because steel can never dissolve old rivalries between provinces.
  3. Rail travel exposed cultural divisions even as it improved physical connections between towns. (correct answer)
  4. Stationmasters should announce arrivals in multiple dialects to help all travelers.

Explanation: The main idea of the text is that rail travel improved physical connections but exposed and magnified cultural divisions between provinces. The passage starts with promises of unity, describes trade and entertainment benefits, then notes persistent sorting by dialect, concluding connection highlights differences. This arc contrasts expectations with realities, focusing on proximity's effects. Choice A is tempting as it lists trade and entertainment increases, positive details but not the central tension. Choice B claims investors wrong about dissolving rivalries, partial but missing magnification. In main idea questions, identify the ironic or contrasting element that drives the author's point.

Question 20

In 2001, astronomer Victor Salinas wrote in Light, Interrupted: Early photographs of a distant galaxy showed uneven brightness, and some researchers suggested the galaxy itself was violently unstable. Salinas reviews later observations and notes that the pattern matched the movement of a faint foreground object that briefly blocked part of the light, much like a small cloud passing a streetlamp. He admits the galaxy contains active regions, but those do not account for the specific dips in brightness. Salinas concludes that before inventing dramatic explanations, astronomers must rule out ordinary interference along the line of sight.

Which choice best states the main idea of the text?

  1. Brightness dips in a galaxy's images were likely caused by foreground interference, not instability. (correct answer)
  2. Distant galaxies are often violently unstable because they contain many active regions.
  3. Streetlamp analogies are the most accurate way to explain astronomical observations to the public.
  4. Early galaxy photographs were unreliable because cameras could not capture even brightness.

Explanation: The main idea of the text is that observed brightness dips in a galaxy's images were likely due to foreground interference rather than intrinsic instability, urging astronomers to rule out ordinary explanations first, as argued by Victor Salinas. The passage presents early interpretations of uneven brightness as violent instability, describes matching patterns to a blocking object like a cloud, acknowledges active regions, and concludes against dramatic claims without checking interference. This arc debunks assumptions with methodical analysis, building to cautious methodology. Choice B is tempting as it generalizes about distant galaxies' instability, an initial suggestion, but the text refutes this for the case, not endorsing it. In main idea questions, focus on the corrective conclusion over preliminary hypotheses.
