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.
Thermometers and timers are unreliable tools for teaching beginners to cook soup.
A traditional saying about cooking conveys the value of attentive technique.
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 1995, historian Mei Takahashi wrote in Maps That Persuade: A wartime government published a map showing enemy territory as a dark stain creeping toward the capital. At first glance the map seems like a neutral report of geography. Takahashi points out, however, that the cartographer enlarged certain regions, omitted distances between cities, and used arrows that implied inevitable invasion. She notes that readers later cited the map as evidence that rationing and censorship were necessary. Takahashi concludes that the map’s persuasive power came not from new facts but from design choices that shaped how citizens imagined threat.
Which choice best states the main purpose of the text?
To claim that maps are inherently unreliable because they always omit some distances,
To argue that a wartime map influenced public opinion through persuasive design choices,
To describe the geographic features of enemy territory near the capital city,
To explain how rationing and censorship policies were implemented during the war,
Explanation
The main purpose of the text is to illustrate Mei Takahashi's argument that a wartime map shaped public opinion through subtle design choices that amplified threat perception, beyond mere geography. The passage describes the map's dark stain and invasion arrows, notes its initial neutral appearance, details manipulations like enlarged regions and omitted distances, and concludes that these persuaded citizens on policies like rationing. This arc reveals hidden persuasion in seemingly factual tools, building from description to analytical payoff. Choice C might tempt by referencing geographic features near the capital, implied in the map, but this is part of the critiqued content, not the purpose. A key strategy is to focus on how the author analyzes an artifact's impact, not just its content.
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?
Unshaded corals recover fully once temperatures fall, making interventions unnecessary.
Algae growth under shade cloth always reduces water flow enough to kill corals.
Shade cloth is a simple fix that reliably prevents coral bleaching during heat waves.
Shading corals can help temporarily but has trade-offs and cannot replace addressing warming.
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.
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?
Museums create controversy when they clean paintings that the public recognizes.
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.
Conservators should always remove all later layers to reveal the original paint.
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.
In 2008, science writer Helen Park wrote in The Peanut Puzzle: For years, parents were told to delay giving infants peanuts to prevent allergies, advice that seemed cautious and sensible. Park recounts how a later clinical trial compared early peanut exposure with avoidance and found fewer allergies in the early-exposure group. She notes that the result does not mean every family should ignore medical guidance, since some infants already show eczema or other risks. Still, Park argues that the episode illustrates a broader lesson: plausible recommendations can persist until rigorous testing reveals that prevention sometimes requires exposure, not avoidance.
Which choice best states the main idea of the text?
Infants with eczema are more likely to develop allergies regardless of peanut exposure timing.
Avoiding peanuts is always the safest approach because peanut allergies are severe and unpredictable.
Early peanut exposure reduced allergies in a trial, showing why advice must be tested rigorously.
Parents should ignore medical guidance because many recommendations are based on guesswork.
Explanation
The main idea of the text is that a trial showing reduced allergies from early peanut exposure highlights the need for rigorous testing of seemingly sensible advice, as discussed by Helen Park. The passage recalls past delay recommendations, describes the trial's counterintuitive results, notes caveats for at-risk infants, and concludes with the lesson that prevention may require exposure. This flow overturns assumptions with evidence, emphasizing methodological caution. Choice C may attract because it mentions eczema as a risk factor, a qualifier, but this refines rather than defines the idea. Choice D supports avoidance, which the text challenges. A key strategy is to identify the 'broader lesson' the author draws from the example.
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 illustrate that baseball debates are the most common form of public fellowship.
To explain why dense signage is necessary to prevent prohibited park behaviors.
To argue that civic design succeeds only when rules and enforcement do not undermine trust.
To describe how ornate benches can beautify a city square and attract visitors.
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 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.
To explain why call centers should reduce training time and increase efficiency metrics.
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.
In 1922, poet Salma Idris wrote in Letters Unsent: I kept your address folded in my pocket, not because I meant to visit, but because it proved the distance had a name. On the train I practiced greetings in my head, then spent them on strangers who would never notice the tremor. When I finally reached your street, I bought oranges from a vendor and watched the peels curl like small maps, each one leading nowhere. Later I told friends the journey was for business, and they admired my efficiency. But the truth is simpler: I traveled to learn that courage can look exactly like turning back.
Which choice best states the main purpose of the text?
To explain how practicing greetings helps travelers speak confidently to strangers.
To describe the sights and commerce of a street vendor selling oranges.
To argue that friends often misjudge efficiency when someone travels for business.
To portray an inward journey in which turning back becomes a form of courage.
Explanation
The main purpose of the text is to portray an inward journey where turning back represents a form of courage learned through travel. The passage details preparations and encounters en route, builds to a moment of observation with oranges, then reflects on the true lesson of courage in retreat. This arc simulates a physical trip that reveals internal growth, contrasting outward efficiency with inner truth. Choice D mentions friends misjudging efficiency, a closing detail but not the purpose of exploring personal realization. Choice C describes the vendor, a scenic element supporting the introspective payoff. For literary texts, the purpose often lies in the thematic resolution, like redefining courage beyond action.
In 2001, musicologist Elena Varga wrote in Listening for the Audience: A composer’s sketches show dozens of discarded endings, which biographers sometimes interpret as indecision. Varga instead compares the drafts to concert reviews from the same season, noting that audiences complained about finales that felt “too abrupt” after long, dense movements. The final version’s extended coda, then, may reflect not weakness but a strategic adjustment to how the piece would be heard in a noisy hall. Varga admits that the composer also enjoyed elaborate codas in other works, so taste played a role. Still, the evidence suggests revision can be a form of communication with listeners, not merely a private struggle.
Which choice best states the main idea of the text?
Draft revisions may reflect a composer’s effort to communicate with audience expectations.
The extended coda was added mainly because the composer preferred elaborate endings.
Noisy concert halls make it impossible for audiences to appreciate dense movements.
Discarded endings prove the composer was indecisive about how to finish the piece.
Explanation
The main idea of the text is that a composer's draft revisions may reflect efforts to align with audience expectations, not just indecision. The passage discusses discarded endings interpreted as weakness, compares to reviews complaining of abruptness, and suggests the coda as strategic, concluding revision as communication. This arc reframes evidence from personal struggle to listener-oriented. Choice A seems close as it calls the composer indecisive, but the text challenges this view. Choice D mentions noisy halls, a detail supporting the argument but not the main idea. A useful strategy is to spot how the author reinterprets common views, which often forms the core claim.
In 2018, urban ecologist Priya Menon wrote in Sidewalk Habitats: A city council proposed replacing several “messy” roadside plantings with uniform turf, arguing that neat lawns signal safety. Menon notes that the shaggy plots host bees and beetles that pollinate nearby community gardens, and that the plots also absorb stormwater during sudden summer downpours. She acknowledges residents’ complaints about ticks and allergens but points out that targeted mowing and signage reduced those concerns in a pilot block. Menon concludes that the city should judge roadside vegetation by what it does, not by how closely it resembles a park lawn.
Which choice best states the main purpose of the text?
To explain why some residents associate tidy lawns with public safety,
To criticize city councils for preferring parks over community gardens,
To describe how a pilot block used signage to address ticks and allergens,
To argue that roadside plantings should be evaluated by their ecological functions,
Explanation
The main purpose of the text is to summarize Priya Menon's argument that roadside plantings should be judged by their ecological benefits rather than their appearance. The passage begins by presenting the city council's proposal to replace 'messy' plantings with tidy lawns for perceived safety, then counters with Menon's evidence of the plots' roles in pollination and stormwater absorption, acknowledges resident concerns, and highlights a successful pilot before concluding with her recommendation to prioritize function. This arc builds from a common aesthetic preference to a broader ecological perspective, showing how initial complaints can be addressed without sacrificing environmental value. Choice A might tempt because it mentions residents' association of tidy lawns with safety, which appears early in the text, but this is just setup for Menon's counterargument rather than the central purpose. Choice C is a supporting detail about the pilot block's solutions, but it serves to bolster the main argument rather than defining the text's overall goal. A key strategy for main purpose questions is to identify what the author ultimately advocates for, ensuring the answer encompasses the conclusion and not just introductory or secondary elements.
