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?
Miso soup tastes harsher when aromatics turn bitter from excessive heat.
Tofu should be handled carefully so it does not crumble during simmering.
A traditional saying about cooking conveys the value of attentive technique.
Thermometers and timers are unreliable tools for teaching beginners to cook soup.
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.
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 explain why dense signage is necessary to prevent prohibited park behaviors.
To illustrate that baseball debates are the most common form of public fellowship.
To describe how ornate benches can beautify a city square and attract visitors.
To argue that civic design succeeds only when rules and enforcement do not undermine trust.
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.
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 argues for banning plastic packaging, then lists alternatives already available.
It defines key chemistry terms, then tests readers with practice questions.
It recounts an invention’s history, then profiles the scientists who funded it.
It introduces a problem, then compares two attempted fixes before drawing a broader lesson.
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.
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.
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.
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 celebrated quartet succeeded because it used daring modulations and returning themes.
Petrov’s classmates were wrong to mock him for copying symphonies by hand.
A composer’s originality can grow from disciplined imitation that develops structural awareness.
Petrov’s early compositions closely resembled the works he transcribed as a student.
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.
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,
To claim that singing competitions should ban microphones and stage lighting to ensure fairness,
To describe why audiences prefer finalists who appear effortless on stage,
To explain how vowel-shape coaching can protect a singer’s range during competitions,
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.
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?
Survey tasks cannot accurately measure how quickly people recover focus after interruptions.
People check their phones mainly to seek relief from frustration during difficult workdays.
Phone notifications are the single most important cause of attention problems in adults.
Frequent phone checking may reflect preexisting attention struggles, complicating simple cause claims.
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.
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 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,
To explain why rereading notes increases students’ confidence even when learning is weak,
To argue that practicing retrieval improves long‑term learning more than rereading notes does,
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.
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 praise bureaucratic recordkeeping as the most reliable guide to port commerce.
To explain how customs ledgers allowed officials to calculate duties with precision.
To argue that preserved records can distort historians’ understanding of everyday trade.
To describe the discovery of a shipowner’s desk filled with sailors’ credit notes.
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.
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 explain why call centers should reduce training time and increase efficiency metrics.
To argue that emphasizing a job’s social impact can improve retention and service outcomes.
To claim that longer calls always lead to more customer complaints and higher turnover.
To describe how peak-season demand inevitably causes burnout among call-center employees.
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.
