From J. Kim, "Notes from the Garden," 2022.
Last spring, our community garden asked residents to volunteer for two-hour watering shifts. The sign-up sheet sat mostly empty; even eager gardeners hesitated to block out large chunks of time. In June we tried something smaller: a task board listing five-minute jobs—refill the rain barrel, clip three tomato suckers, sweep the gate path. People started stopping by on their way home, checking off a square, and chatting before leaving. By July, every bed looked cared for, and we met more neighbors than we had during entire seasons. The change was not expensive or dramatic, but it lowered the barrier to participation. When we design projects as a series of small, visible wins, we make it easier for people to show up.
Which choice best states the main purpose of the text?
To criticize residents for failing to commit to longer shifts
To show that breaking tasks into small steps increased community participation
To argue that gardens require professional management to thrive
To compare the effectiveness of different watering techniques
Explanation
The text emphasizes that smaller, simple tasks led to greater involvement. The other choices either misstate the tone, focus on an unrelated claim, or elevate a narrow detail beyond the passage's main point.
Farmers often assume that introducing domestic honeybees is the most efficient way to increase crop yields. Recent studies, however, show that diverse wild pollinator communities can be equally, if not more, effective. As a result, farms bordering wildflower corridors tend to report higher yields than similar farms without such habitat. These corridors provide continuous bloom across seasons, sustaining bees, flies, and beetles that pollinate at different times of day and under varied weather conditions. The studies also note that wild pollinators are less synchronized, reducing the risk that a single cold spell disrupts all activity. While managed hives remain useful, the data suggest that conserving hedgerows and field margins offers a cost-effective, resilient strategy for boosting production while supporting local biodiversity.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
Introduces a competing hypothesis about pollination.
Concedes an exception to the preceding claim.
Provides evidence that supports the claim about the benefits of wildflower corridors.
Defines a technical term introduced earlier.
Explanation
The sentence reports a concrete outcome (higher yields) that supports the claim about wildflower corridors. The other options mischaracterize its role: it neither introduces a new hypothesis, admits an exception, nor defines a term.
Cities seeking relief from heat increasingly invest in urban trees. Studies show that tree canopies intercept sunlight and promote evapotranspiration, lowering street-level temperatures and reducing energy demand for cooling. For instance, a single mature oak can transpire dozens of gallons of water per day, cooling the surrounding air. Beyond comfort, these microclimate effects have public health implications: fewer heat-related illnesses and improved air quality. Critics note maintenance costs, but those expenses are typically outweighed by energy savings and health benefits. Consequently, urban forestry programs have shifted from beautification to infrastructure planning, where shading corridors are mapped with the same care as transit routes.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
Introduces a counterargument to the passage's claim.
Defines a technical process referenced earlier.
Provides a concrete example that illustrates the preceding claim.
Anticipates an objection about program costs.
Explanation
The sentence offers a specific example (a mature oak's transpiration) that illustrates how trees cool cities. It neither defines a term nor presents a counterargument or cost-related objection.
City planners long treated vacant lots as eyesores best fenced off. On my block, neighbors proposed something different: a community garden bordered by salvaged bricks, sown with tomatoes, herbs, and marigolds. The city supplied compost; a retired carpenter built raised beds from scrap. By midsummer, the lot that had collected wrappers and windblown weeds held picnic benches and a chalkboard where Saturday recipes were scrawled. Children learned which leaves smelled like lemons; teenagers swapped watering shifts. We still buy groceries, of course, but the harvest has changed the street. People who once hurried past now linger to trade seedlings and news. The garden is small, and it will not solve every problem, yet it has made a neglected space useful, inviting, and shared.
Which choice best states the main purpose of the text?
Describe the steps needed to establish a citywide urban farming mandate.
Show how community gardens can transform neglected spaces into shared assets.
Argue that individual home gardens are superior to public plots.
Recount the history of farming practices in the region.
Explanation
The passage emphasizes how a community garden improved a vacant lot and strengthened neighborhood ties. The other choices either propose policies not discussed, make a comparison the text does not make, or broaden the scope to regional history.
Urban forests are often praised for cooling cities, filtering air, and supporting wildlife. Municipal reports list tree planting as a cost-effective climate strategy. However, these benefits are unevenly distributed across neighborhoods. Studies show wealthier areas have denser canopies, while low-income districts face hotter summers and poorer air quality. Recognizing this imbalance, planners now map tree cover alongside income and health indicators. Doing so allows programs to prioritize blocks where new shade would reduce heat stress most. Equity-focused planting, the argument goes, can turn a general good into a targeted public health intervention. This shift reframes canopy as infrastructure, not ornament.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
Introduces the passage's central claim.
Provides a counterexample to a cited study.
Introduces a limitation to the preceding benefits, setting up the need for equitable planning.
Summarizes the passage's main ideas.
Explanation
The sentence highlights an inequity that complicates the general praise and sets up the equity-focused measures that follow. The other choices miscast it as a claim, a counterexample, or a summary.
Lina Ortiz, 2019, City Trees. In a city where summers are hotter each year, planting street trees is one of the simplest investments we can make. A single mature tree cools the block, catches stormwater before it floods basements, and filters air that triggers asthma. The price of a sapling and a watering bag is small compared with the cost of heat-related emergency visits. Some residents worry about leaves clogging gutters or roots lifting sidewalks; those concerns are real, but they are manageable through routine maintenance. What we cannot manage, once the asphalt has absorbed a day's heat, is the discomfort we all share. When public dollars are scarce, we should spend them where they do the most good for the most people. Plant the trees now; their shade will repay us for decades.
Which choice best states the main purpose of the text?
To compare the costs of emergency medical care to home repairs
To advocate that the city prioritize planting street trees for broad public benefits
To propose a comprehensive solution to all urban environmental problems
To argue that trees are too burdensome to maintain in dense neighborhoods
Explanation
The text urges the city to plant more street trees because of multiple shared benefits. The other choices are too narrow, too broad, or misstate the author's position as anti-tree.
Last spring, our block converted a weed-choked strip beside the laundromat into a small garden of native flowers. The plot is hardly grand: a few square yards of coneflower, milkweed, and asters squeezed between a fence and the sidewalk. Yet by mid-summer, bees stitched the air from dawn to dusk, and we counted three species of butterflies we had never noticed before. Neighbors lingered to watch, swapping watering shifts and seed packets. When a child pointed out a monarch caterpillar fattening on milkweed, the group fell silent, delighted. The garden did not change the skyline or erase traffic, but it reminded us how even tiny, intentional patches can restore corridors for pollinators that the city has paved over.
Which choice best states the main purpose of the text?
To argue that city budgets should prioritize parks over roads
To explain how even small urban gardens can support pollinators and community engagement
To recount the history of a single vacant lot on one block
To refute claims that native plants are unattractive in dense neighborhoods
Explanation
The text emphasizes that a modest native-plant garden meaningfully supports pollinators and neighbors. The other choices are too broad (A), too narrow (C), or miscast a rebuttal the text does not make (D).
Each spring and fall, billions of birds migrate across continents, navigating largely at night by starlight. In brightly lit cities, however, artificial illumination can disorient these travelers, drawing them into glass-heavy skylines where collisions are common. Ornithologists estimate that urban lighting contributes to the deaths of millions of birds annually. To address this, several cities have adopted 'lights-out' policies during peak migration. The measures are simple: office towers dim nonessential lights after dusk, and landmarks go dark for a few critical weeks. Early reports from participating cities indicate fewer fatal strikes, especially on overcast nights when celestial cues are obscured. While not a complete solution, coordinated reductions in nighttime lighting represent a relatively low-cost intervention with measurable benefits.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
Introduces historical background about migration patterns
Provides a counterexample to a previous claim
Presents a solution to a problem described earlier
Defines a technical term used in the passage
Explanation
It presents a solution to the problem of bird disorientation caused by urban lighting. The other choices mischaracterize the sentence as background, a counterexample, or a definition.
Last winter the lot on Maple and Third was a tangle of chain-link fence and stubborn weeds. By May, neighbors had hauled away tires, layered compost, and marked out beds with twine. Children planted beans alongside retirees who remembered when the block had elm trees. Their Saturday harvest table is small, but it draws conversations that never happened at the old bus stop. City inspectors noticed a drop in litter along the block, and a nearby cafe now buys herbs grown here. The garden has not solved every problem; volunteers still patch leaky hoses and shoo off raccoons. Yet the street feels claimed rather than ignored, and passersby slow to look at the sunflowers.
Which choice best states the main purpose of the text?
to instruct readers on how to start a community garden
to explain how a community garden revitalized a neglected space
to argue that city officials should increase fines for littering
to criticize volunteers for failing to fix all problems
Explanation
The passage describes how a community garden transformed a neglected lot and its surrounding block. The other choices either propose instructions or policies the passage does not offer or fixate on problems mentioned only briefly.
Studies of agricultural landscapes increasingly emphasize the role of pollinator diversity in stabilizing crop yields. When multiple bee and fly species visit blossoms at different times and under varying weather, flowers receive more consistent pollen delivery. For example, apple orchards bordered by wildflower meadows tend to set more fruit than those surrounded by bare fields. This pattern holds even when total numbers of pollinators are similar, suggesting that variety, not just abundance, matters. As climate conditions become less predictable, farmers who maintain habitat strips may buffer their harvests against sudden pollinator shortages. The goal is not to replace managed honeybees but to complement them with native species that thrive in local conditions.
Which choice best describes the function of the underlined sentence in the overall structure of the text?
Introduces a counterclaim that challenges the main point
Defines a technical term used in the discussion
Provides a concrete example that illustrates the preceding claim
Describes a methodology for measuring pollination
Explanation
The sentence offers a specific orchard example to illustrate the claim that diversity supports yield stability. It does not define a term, present a counterclaim, or outline a method.
