From 'Small Steps to a Walkable City' (2021), by Lila Moreno. Officials often announce 'transformative' plans such as subway expansions and car-free corridors, but the most durable gains in walkability usually come from smaller, repeated acts. Seville's quick-build bike lanes, laid with paint and plastic bollards, boosted ridership before any grand redesign. Paris's celebrated '15-minute city' emerged not from a single blueprint but from many trials such as school streets, widened corners, and pop-up plazas that persisted because residents used them. Not every place can spend billions or remake its map, and in any case, sweeping visions can falter under budget shortfalls and politics. Cities should start with what they can test: slow traffic near schools, fix crossings where crashes cluster, add benches on routes to clinics, measure results, and keep what works. Walking thrives when small improvements accumulate into a network people actually trust.
Which choice best states the main purpose of the text?
To recount the history of European walkability initiatives
To advocate for incremental, testable steps to improve urban walkability
To criticize the '15-minute city' as unrealistic
To argue that only major transit projects can reduce car dependence
Explanation
B is correct because the author argues that small, testable interventions build walkability more reliably than grand plans. A focuses narrowly on European examples, C misreads the stance as anti–'15-minute city,' and D states the opposite of the claim.
Many historians once assumed that Bronze Age coastal villages were isolated, subsisting on local resources with little contact beyond neighboring bays. Recent excavations, however, have uncovered imported pottery and metalwork in several small harbors. Because these goods appear alongside locally produced tools, they likely arrived through routine exchange rather than rare ceremonial visits. This pattern suggests a web of everyday trade that tied even modest settlements into regional markets. While not all sites show such evidence, the consistent mix at multiple locations challenges the older view of isolation. Further analysis of residues on the pottery indicates origins across different river systems, reinforcing the interpretation.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
Introduces a new line of evidence unrelated to trade activity
Provides background on how the goods were manufactured
Acknowledges a limitation in the archaeological record that weakens the claim
Interprets the artifact context to argue that exchange was routine, not exceptional
Explanation
It interprets the co-occurrence of imported goods with local tools to support the claim of regular trade. It does not add unrelated evidence (A), supply manufacturing background (B), or emphasize a limitation (C).
From 'The Tarnish' (2015) by Mara Das. I found my grandmother's spoon at the back of a drawer, its bowl bruised thin and its handle dulled to a soft shadow. I thought first of polish and a place on the shelf. Then, turning it in my hand, I felt the faint ridges where her thumb had worn the metal smooth. This spoon stirred tamarind stew through lean months and rich, tapped the side of a pot like a metronome while she listened for the right simmer. The shine I imagined suddenly seemed beside the point; the gray held the hours she could not spare and never counted. I rinsed it, dried it, and slid it beside my own ladle, leaving the tarnish to keep speaking.
Which choice best states the main idea of the text?
The narrator decides to learn their grandmother's recipes by cooking every weekend.
The narrator argues that antiques should be restored to their original shine.
The narrator describes the exact process used to make tamarind stew.
The narrator comes to value an heirloom's wear as a record of a grandmother's labor.
Explanation
D is correct because the narrator realizes the spoon's tarnish and wear embody the grandmother's work and time. A and C add actions or details not in the text, and B contradicts the narrator's choice.
Urban trees cool neighborhoods by casting shade and releasing water vapor through transpiration. Multiple studies in North American cities report that streets with mature canopy can be several degrees cooler on summer afternoons than adjacent blocks lacking trees. The benefits extend beyond heat relief: leaves filter particulates, and tree-lined streets are associated with lower traffic speeds and reduced noise. While these effects vary by species and spacing, the direction of the impact is remarkably consistent across contexts. Therefore, even small increases in street-tree planting can produce measurable public health gains. Municipal budgets are limited, but cost-benefit analyses often show that maintenance expenses are offset by energy savings and improved health outcomes within a few years.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
Introduces a counterargument to the passage's main claim
Draws an overarching conclusion from the evidence presented earlier
Defines a key term used throughout the passage
Describes a specific research method employed in the studies
Explanation
The sentence synthesizes prior evidence to state a broad conclusion about public health benefits. It does not present a counterargument, define a term, or detail a method.
City Parks Department Update (2022). Beginning in early May, crews will renovate Maple Square Park to make it more welcoming and accessible. Paths will be widened for wheelchairs and strollers, worn playground equipment will be replaced, and native shrubs will be planted to support pollinators. The lawn will be open most weekdays while work proceeds in sections, and completion is expected in about eight weeks. To help neighbors enjoy the park during construction, the department will host weekend music and story hours on the north lawn. Residents are invited to volunteer at a community planting day and to donate to the Friends of Maple Square for additional benches. For schedule updates, visit the Parks Department website.
Which choice best states the main purpose of the text?
To persuade residents to oppose the renovation timeline at Maple Square Park
To inform residents about upcoming renovations and invite them to participate
To compare Maple Square Park with other city parks in the region
To argue that native plants are more attractive than ornamental species
Explanation
The text announces the renovation schedule, describes changes, and invites volunteers and donors, so its purpose is to inform and encourage participation. The other choices either introduce arguments or comparisons the passage does not make or narrow the focus to one detail.
Archaeologists increasingly deploy airborne lidar to map buried structures beneath dense forest canopies. By sending laser pulses from aircraft and measuring their returns, researchers generate digital terrain models that reveal roads, terraces, and city grids hidden by vegetation. These datasets can be produced over large regions in days, offering a synoptic view that ground surveys rarely achieve. Spectacular finds in Central America have reshaped estimates of ancient population density. Critics caution, however, that remote sensing can mislead when features resemble natural formations. Yet lidar does not replace excavation; it guides it. Teams still verify anomalies with trenches, radiocarbon samples, and artifact analysis to establish dates and functions.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
Presents a surprising result that contradicts earlier data
Provides a detailed example of a lidar discovery
Restates the passage's thesis in different words
Qualifies the preceding discussion by clarifying how lidar should be used
Explanation
The sentence qualifies the prior enthusiasm and caution by positioning lidar as a guide rather than a replacement. It neither reports a specific result, offers an example, nor restates the thesis.
Translating literature involves more than swapping words between languages. A translator must capture tone, rhythm, and cultural references that give a text its character. Idioms pose a particular challenge because their literal meanings often mislead. For instance, the French expression 'avoir le cafard' does not involve insects at all; it conveys a mood of melancholy. When translators choose an English equivalent like 'feeling blue,' they preserve the emotional register while adapting the imagery. Even punctuation choices can shift the perceived voice of a narrator. Such choices are interpretive, not mechanical, which is why good translations read as original works in their own right.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
Introduces a new argument that changes the passage's focus
Summarizes the passage's main conclusion
Provides a concrete example that illustrates a previously stated challenge
Defines the term "idiom" for the first time
Explanation
The sentence offers a specific example that illustrates the challenge of translating idioms. It does not shift the argument, summarize the whole passage, or define the term.
from The Quiet Aisle (2019) by Marisol Vega. I had not stepped into the Alder Street Library in years, but the smell of paper and dust met me like an old friend. The card catalog had vanished, replaced by patient screens, and the carpet no longer bore the constellation of coffee stains I once traced with my shoe. Yet a familiar squeak rose from the third stair, and sunlight still pooled in the reading room at four. I found my childhood corner and, without thinking, reached for a chair that seemed to remember the shape of my impatience. The shelves had shifted, and the books wore new jackets, but when I opened one, the room narrowed to a page and a pulse I knew. The place had changed; the welcome had not.
Which choice best states the main idea of the text?
To recount the sound of a particular stair that squeaked in the library
To argue that public libraries are essential to democracy
To celebrate the replacement of outdated systems with new technology
To reflect on how a familiar place has changed while its meaning endures
Explanation
The narrator acknowledges changes in the library while emphasizing that its welcome and personal significance remain. The other choices elevate a single detail, introduce an unsupported civic claim, or miscast the tone as technological celebration.
Memo: Urban Heat Initiative, City Sustainability Office (2021). Summer temperatures in the downtown core routinely exceed those in surrounding neighborhoods, in part because dark pavement absorbs and radiates heat. To address this problem, the city applied a reflective sealant to 20 blocks of asphalt last July. Sensors recorded afternoon surface temperatures 10 to 12 degrees lower on treated blocks compared with untreated ones, and residents reported more comfortable walks. The pilot also exposed challenges: the coating dulled under heavy traffic and required additional sweeping to manage glare-related debris. Based on these results, the office recommends a phased expansion prioritizing school routes and municipal lots with existing shade trees, along with a maintenance schedule to preserve performance. A report to the council will outline costs and timelines next month.
Which choice best describes the overall structure of the text?
It introduces a problem, reports on a small-scale test solution, and outlines next steps.
It narrates the historical rise of urban heat from ancient times to today.
It compares two competing technologies and chooses the better one.
It lists budget items and explains their funding sources.
Explanation
The memo identifies a problem, summarizes a pilot program's results and challenges, and recommends phased expansion. The other choices describe structures not present, such as history, comparison, or budgeting.
To reconstruct past climates, researchers often analyze tree rings, whose widths reflect annual growth conditions. In semi-arid regions, wider rings typically correspond to wetter years, allowing scientists to infer precipitation patterns over centuries. Statistical models calibrate ring width against instrumental rainfall records to generate regional drought indices. By positing a linear relation between ring width and moisture, the model risks oversimplifying multi-causal growth patterns. Still, when validated against independent evidence—such as lake sediments—ring-based reconstructions can clarify the frequency of extreme droughts.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
Acknowledges a limitation of the modeling approach to temper the preceding explanation
Introduces a historical example that supports the study's conclusions
Provides a definition of a technical term used in the passage
States the passage's main claim about the superiority of tree-ring data
Explanation
The sentence flags a methodological limitation, moderating the prior description of the model. It does not introduce an example, define a term, or assert overall superiority.
