Topic DevelopmentQuestion 1 of 20

A student writes this paragraph about citizen science projects that track birds:

Birdwatchers contribute to science by recording sightings on apps and websites. When thousands of participants submit observations, researchers can map migration routes and see how timing changes from year to year. Because the data come from many skill levels, projects often include built-in photo guides and prompts that encourage careful identification. The result is a large, continuously updated dataset that would be difficult for a small research team to collect alone.

The writer wants to add a sentence after the third sentence that explains how projects improve data reliability. Which choice best accomplishes this?

Birds use a variety of calls, including songs for attracting mates and alarm notes for warning others.

Some birdwatchers keep life lists, recording every species they have ever seen in any location.

Binoculars are sold in a range of magnifications, and some models are designed to be waterproof.

Many platforms flag unusual reports—such as a rare species in winter—and ask for a photo or expert review before adding the sighting to maps.

Question 1

A student writes this paragraph about citizen science projects that track birds:

The writer wants to add a sentence after the third sentence that explains how projects improve data reliability. Which choice best accomplishes this?

Birds use a variety of calls, including songs for attracting mates and alarm notes for warning others.
Some birdwatchers keep life lists, recording every species they have ever seen in any location.
Binoculars are sold in a range of magnifications, and some models are designed to be waterproof.
Many platforms flag unusual reports—such as a rare species in winter—and ask for a photo or expert review before adding the sighting to maps. (correct answer)

Explanation: This question tests relevance: an inserted sentence has to accomplish the specific purpose named in the prompt, which here is explaining how projects improve data reliability. The sentence about platforms flagging unusual reports, such as a rare species in winter, and requesting a photo or expert review before adding the sighting to maps describes an actual verification step, and it follows naturally from the point that 'the data come from many skill levels.' The other options stay on the general topic of birds and birdwatching without touching data quality: bird calls for attracting mates and warning others describe animal behavior, life lists describe a hobbyist habit, and binocular magnifications and waterproofing describe equipment. Turn the prompt into a question — 'how do projects make the data more reliable?' — and choose the only sentence that answers it directly.

Question 2

A student is drafting a short essay about the value of translating poetry. The draft reads:

[1] Translating a poem is not the same as swapping each word for its dictionary equivalent. [2] A translator has to decide which features to preserve—sound, rhythm, imagery, or literal meaning—when not all of them can survive the move into another language. [3] Some translators add brief notes to explain cultural references that would otherwise be confusing. [4] Poetry has existed for a long time in many cultures. [5] Even when a translation cannot match every nuance, it can still carry a poem's central emotion to new readers.

The writer wants Sentence 4 to elaborate on the challenge described in Sentences 1–3 without drifting into a broad, unfocused statement. Which choice best replaces the underlined sentence?

NO CHANGE
Because metaphors and wordplay often rely on local history and everyday speech, translators must sometimes invent new phrasing that creates a similar effect for their audience. (correct answer)
Some poems are short, while others are long enough to fill an entire book.
Many readers enjoy poetry because it can be read silently or performed aloud at public events.

Explanation: This question tests relevance and focused development: an added or replacement sentence must extend the specific idea the surrounding sentences build. Sentences 1 through 3 are all about the translator's dilemma — choosing which features to preserve when 'not all of them can survive the move into another language' — so the winner is the sentence explaining that because metaphors and wordplay rely on local history and everyday speech, translators must invent new phrasing that creates a similar effect. It names a concrete source of the difficulty and a concrete response to it, and it sets up Sentence 5's point about carrying a poem's central emotion. Keeping 'Poetry has existed for a long time in many cultures' is exactly the broad, unfocused statement the question warns against; noting that some poems are short while others fill a book and that readers enjoy poetry silently or aloud are true but say nothing about translating. Before choosing, state the paragraph's specific topic in a few words and reject any sentence that is merely about the general subject rather than that topic.

Question 3

A student writes a paragraph about why some companies are switching to four-day workweeks:

Several businesses have experimented with four-day workweeks without reducing pay. Supporters argue that a shorter week can improve focus by encouraging teams to plan meetings more carefully and limit distractions. In some trials, companies reported that productivity stayed the same or even increased. Employees also reported lower stress and fewer sick days.

The student wants to add a sentence after the third sentence that provides the most relevant evidence for the claim about productivity. Which choice best accomplishes this?

Some employees use their extra day off to run errands that would otherwise take time during the workweek.
Some industries, such as emergency services, must staff positions around the clock regardless of schedule changes.
Many offices provide coffee and tea in shared kitchens to help workers take short breaks.
In one six-month pilot, a customer-support team handled roughly the same number of tickets per week after cutting meeting time and rotating coverage. (correct answer)

Explanation: This item tests relevance: added evidence must support the specific claim named in the question, here that 'productivity stayed the same or even increased.' The sentence about a six-month pilot in which a customer-support team 'handled roughly the same number of tickets per week after cutting meeting time' does exactly that, giving a measurable output over a stated period and echoing the paragraph's point about planning meetings more carefully. The sentence about employees running errands on their day off describes personal convenience, not work output. The sentence about emergency services staffing around the clock raises a limitation on scheduling rather than evidence about productivity, and the sentence about coffee and tea in shared kitchens is an office amenity unrelated to the claim. Restate the claim in your own words first, then keep only the choice that measures that exact thing.

Question 4

A writer is drafting a paragraph about a city program that plants trees to reduce summer heat. Read the draft.

[1] In the hottest months, some neighborhoods can be several degrees warmer than others because they have fewer trees and more dark pavement. [2] To address this, the city is planting hundreds of street trees and prioritizing blocks with little existing shade. [3] The program also trains residents to water young trees during their first two summers, when roots are still developing. [4] Tree leaves come in many shapes, including needles, lobes, and smooth ovals. [5] Over time, increased shade can lower surface temperatures and make walking and waiting at bus stops more comfortable.

The writer wants to replace Sentence 4 with a detail that directly supports the paragraph's discussion of neighborhood heat and shade. Which choice is best?

Some trees produce flowers in spring, and others produce fruit that can attract birds and small mammals.
Many people can identify trees by their bark patterns, which may be rough, peeling, or deeply furrowed.
By blocking sunlight and releasing water vapor through their leaves, trees can cool the air around them, especially along streets with wide, unshaded sidewalks. (correct answer)
Some neighborhoods have older houses, while others have newer apartment buildings with different architectural styles.

Explanation: When a question asks you to replace a sentence with a detail that supports a specific discussion, the winning choice must connect to the exact ideas the paragraph is developing, not merely to the general topic of trees. This paragraph is about heat and shade, from neighborhoods that 'can be several degrees warmer than others' to shade that 'can lower surface temperatures,' so the sentence explaining that trees cool the air by blocking sunlight and releasing water vapor, 'especially along streets with wide, unshaded sidewalks,' is the one that supplies the missing mechanism. The details about spring flowers and fruit that attracts birds, about identifying trees by bark patterns, and about older houses versus newer apartment buildings are all true-sounding and all off-target, because none of them mentions heat, shade, or cooling. Leaving the original sentence about leaf shapes has the same problem: leaves appear, but heat does not. Name the paragraph's specific claim in your own words first, then pick the choice that contains that claim's key terms.

Question 5

PASSAGE IV The Violin Doctor [1] In a small, dust-mote-filled workshop in Chicago, Elena creates voices. She is a luthier, a craftsperson [36] who specializes in the repair and restoration of stringed instruments. While the world is full of mass-produced violins, Elena works on the "sick" ones—antique instruments that have suffered centuries of wear, weather, and neglect. Her patients are often older than the country she lives in. [2] To the untrained eye, a crack in a violin's body looks like a simple fracture in wood. To Elena, it is a wound in the instrument's soul. [37] Fixing it requires more than just glue, it demands an understanding of physics, chemistry, and history. She begins by removing the top plate, a delicate operation performed with a thin, heated knife. Once the instrument is open, she can see the internal architecture: the bass bar, the soundpost, and the lining strips. [3] [38] Elena's most recent project was a cello from 1790. It had been crushed in a shipping accident, its ribs splintered and its varnish scarred. Most luthiers would have declared it a total loss. Elena, [39] however, saw potential. She spent three months humidifying the wood to restore its shape. Then, using tiny "cleats"—small squares of spruce—she reinforced the cracks from the inside. [40] Each cleat had to be carved by hand to match the grain of the original wood. [4] The final step is the varnish. Modern synthetic varnishes are durable, but they stifle the sound. Elena mixes her own recipes using natural resins like amber, mastic, and sandarac. She applies the varnish in microscopic layers, [41] polishing each one with a cloth dipped in olive oil and rottenstone. This process can take weeks, but it is essential. The varnish must protect the wood while allowing it to vibrate freely, a paradox that has challenged makers for centuries. [5] When the cello was finally strung and tuned, Elena played a single low note. The sound was rich and dark, filling the small room with a resonance that felt physical. It was no longer a broken collection of wood; it was a living thing again. [42] Elena smiled, wiping the rosin dust from her hands. She isn't just fixing instruments; she is preserving history, one note at a time. [43]

Which choice provides the most effective transition from the previous paragraph?

NO CHANGE
Violins are smaller than cellos.
To illustrate the difficulty of her work, consider her latest challenge. (correct answer)
Woodworking is a dangerous profession.

Explanation: A transition sentence has to name the relationship between the paragraph that just ended and the one beginning. The paragraph before this one describes Elena's general repair process, ending with what she can see once the instrument is open: the bass bar, the soundpost, and the lining strips. The paragraph that follows tells the story of one badly damaged instrument, so the transition must signal a move from general process to specific case, which is exactly what 'To illustrate the difficulty of her work, consider her latest challenge.' does. Keeping the original wording, 'Elena's most recent project was a cello from 1790,' does introduce the cello but announces nothing about why it is being introduced, leaving the shift for the reader to infer. The remark that violins are smaller than cellos compares two instruments the passage is not contrasting, and the claim that woodworking is a dangerous profession raises a risk the passage never discusses. When a question asks for a transition, read the last sentence before the gap and the first sentence after it, then pick the option that names the relationship between them.

Question 6

PASSAGE V: The River of Grass

¹ In the early twentieth century, the general consensus regarding the Florida Everglades was that it was a useless, disease-ridden swamp. Developers and politicians viewed the millions of acres of wetlands as a problem to be solved. They embarked on massive drainage projects, digging canals and building levees to convert the marsh into dry, arable land for farming and real estate. For decades, the destruction of the Everglades was celebrated as a triumph of human engineering over nature. (41)

² One woman, (42) however, saw the Everglades differently. Marjory Stoneman Douglas, a freelance writer and journalist, moved to Miami in 1915. She spent years exploring the vast wetlands, observing the intricate balance of the ecosystem. In 1947, she published a groundbreaking book titled The Everglades: River of Grass.

³ The title itself was revolutionary. By calling it a "river," Douglas completely reframed how the public understood the region. She explained that the Everglades was not a stagnant swamp, but a wide, shallow sheet of water flowing imperceptibly slowly from Lake Okeechobee southward to the Florida Bay. (43) This sheet of water, rarely more than knee-deep, supported a staggering diversity of wildlife. Douglas vividly described the sawgrass marshes, the cypress domes, and the delicate wading birds that relied on the seasonal floods.

⁴ Douglas's book was a bestseller, (44) and it catalyzed the early environmental movement. She fiercely argued that draining the wetlands was ecological suicide. Without the slow flow of freshwater, the underground aquifers that supplied South Florida's drinking water would dry up or become contaminated by saltwater intrusion from the ocean. (45) In addition, the dry peat soil of the drained marshes became highly flammable, leading to massive, uncontrollable muck fires.

⁵ Despite the success of her book, the drainage projects continued. (46) Infuriated by the government's inaction, Douglas founded the Friends of the Everglades in 1969, when she was 79 years old. For the next thirty years, she was a relentless advocate for the wetlands. She attended public hearings, organized protests, and famously stated, "The Everglades is a test. If we pass it, we may get to keep the planet."

⁶ Today, the Comprehensive Everglades Restoration Plan is the largest environmental restoration project in history. Engineers are currently working to undo the damage of the past century by filling in canals and allowing the water to flow naturally once again. (47) While the ecosystem is still threatened by pollution and climate change. (48) It is widely acknowledged that the Everglades would likely have been paved over completely if not for Marjory Stoneman Douglas. (49) Her legacy is a reminder that a single voice, armed with a profound understanding of nature, can change the course of history. (50)

Which choice most effectively concludes the essay?

NO CHANGE — Her legacy is a reminder that a single voice, armed with a profound understanding of nature, can change the course of history. (correct answer)
She lived to be 108 years old, passing away in 1998.
The Florida panther is still highly endangered today.
Many schools and parks in Florida are now named after her.

Explanation: The correct answer is A (NO CHANGE). The essay traces Marjory Stoneman Douglas's journey from observer to author to activist, building to a central argument: that one person with knowledge, passion, and persistence can have a transformative impact on the natural world. The concluding sentence 'Her legacy is a reminder that a single voice, armed with a profound understanding of nature, can change the course of history' directly captures this argument in universal, resonant terms. It elevates Douglas's story from a biographical account to a broader lesson — which is the hallmark of a strong essay conclusion. B (she lived to be 108 years old) is a biographical trivia fact with no thematic resonance — it tells us something interesting but adds nothing to the essay's argument. C (the Florida panther is still endangered) introduces a new environmental concern unconnected to Douglas's work or legacy. D (schools and parks are named after her) is a minor honor that understates her actual impact — the essay has argued she saved an entire ecosystem, and naming a park after her is a weak ending to that story. On conclusion questions, the right answer always connects back to the essay's central argument and provides thematic closure rather than adding new, unrelated facts.

Question 7

A student is drafting an essay about how city parks can support wildlife. The draft reads:

[1] In many cities, parks are designed mainly for people: open lawns, paved paths, and bright nighttime lighting. [2] But small design changes can make these spaces friendlier to birds and insects without reducing their usefulness for visitors. [3] For example, replacing some lawn with native plants provides food and shelter for pollinators. [4] Leaving a few fallen logs in an out-of-the-way corner can create habitat for beetles and fungi. [5] There are many different kinds of parks in the world.

The writer wants to add a concluding sentence that reinforces the paragraph's main idea (specific design changes that help wildlife). Which choice best replaces the underlined sentence?

Because cities contain so many people, parks often need to be large enough to host concerts and sports tournaments.
NO CHANGE
Thoughtful features like native plantings and small "wild" areas can turn an ordinary park into a healthier ecosystem for urban species. (correct answer)
Some park visitors prefer wide sidewalks because they make it easier to walk in groups.

Explanation: This question asks you to identify a concluding sentence that reinforces the paragraph's main idea about specific design changes that help wildlife. The paragraph establishes that small changes can make parks wildlife-friendly without reducing human usefulness, then provides concrete examples like native plants and fallen logs. Choice C effectively concludes by summarizing how thoughtful features can transform parks into healthier ecosystems, directly reinforcing the main idea. The original sentence (B) is far too broad and unfocused, merely stating an obvious fact about park variety. Choices A and D focus on human needs rather than wildlife benefits, missing the paragraph's central purpose. A strong concluding sentence should echo the paragraph's specific focus while providing closure, not introduce new or tangential ideas.

Question 8

"Turn Right at the Big Pine\n\nMy father believed that road maps were for people who lacked a sense of adventure. He preferred to navigate by instinct, landmark, and the occasional contradictory tip from a gas station attendant. Consequently, [19] our annual family trips to the Cedar Creek campground were rarely straight lines; they were sprawling, improvisational loops through the backroads of Oregon.\n\nI was ten years old, sitting in the backseat of our station wagon, squeezed between a cooler full of soda and my sleeping brother. The air outside was thick with the scent of pine and dust. We had been driving for six hours, [20] but according to Dad, we were "just around the river bend." He pointed to a massive, gnarled tree standing sentinel at a fork in the road. "That's the Big Pine," he declared with the confidence of a ship captain spotting land. "We turn right here."\n\nWe turned right. The pavement immediately gave way to gravel, and the road narrowed until the blackberry bushes were scraping the sides of the car. My mother, who had been quietly reading a novel, looked up. "Honey," she said, her voice dropping an octave, "I don't think this is the way to the campsite." Dad waved a hand dismissively. He insisted that this was a shortcut he had discovered years ago. [21]\n\nTen minutes later, the road ended abruptly at a rusted gate marked "Private Property." A cow stared at us blankly from the other side. Silence filled the car. The cow chewed its cud, looking entirely unimpressed by our arrival. [22] Without a word, Dad shifted the car into reverse. As we backed down the dusty trail, he caught my eye in the rearview mirror and winked. "Well," he said, "now we know what's down that road." For him, the wrong turn wasn't a mistake; it was just another part of the story. [23]\n\n[1] We eventually found the campsite, arriving just as the sun was setting behind the mountains. [2] I realized then that the destination mattered less to him than the wandering it took to get there. [3] Years later, when I drive [25] my own kids on vacation, I keep a GPS on the dashboard. [4] But sometimes, when I see a strange road winding off into the trees I feel [24] a familiar tug to turn the wheel."

Which choice best concludes the paragraph by connecting the specific event to the father's general philosophy?

NO CHANGE (correct answer)
We were all very hungry and ready to eat dinner.
My mother shook her head and went back to reading her book.
It was getting late, and we still had to set up the tent.

Explanation: This is a topic development question testing concluding sentences and thematic connection. You can tell because the question asks which choice "best concludes the paragraph by connecting the specific event to the father's general philosophy." This requires you to link a concrete narrative moment to an abstract theme. For questions about concluding sentences, identify the paragraph's main point or the essay's central theme, then choose the sentence that most effectively ties specific details back to that larger idea. Strong conclusions create coherence by showing readers why the specific example matters in the bigger picture. Avoid mundane details that don't provide thematic insight. Choice A (NO CHANGE) is correct because "For him, the wrong turn wasn't a mistake; it was just another part of the story" directly connects the specific wrong-turn event to the father's general philosophy of treating life as an adventure. This echoes the essay's opening: "road maps were for people who lacked a sense of adventure." The sentence reveals his worldview—mistakes are adventures, detours are part of the experience. This creates thematic unity. Choice B ("We were all very hungry and ready to eat dinner") is a mundane practical detail that doesn't connect to any larger philosophy or theme. It's just a fact with no thematic resonance. Choice C ("My mother shook her head and went back to reading her book") provides a character reaction but doesn't articulate or connect to the father's philosophy about adventure and wandering. Choice D ("It was getting late, and we still had to set up the tent") is another practical detail about logistics that fails to provide any thematic insight or philosophical connection. Remember: Strong concluding sentences do more than state facts—they reveal meaning and connect specific events to larger themes. Pro tip: When the ACT asks for a sentence that "connects specific to general" or "concludes by showing the significance," look for the option that contains abstract or philosophical language ("philosophy," "belief," "meaning," "significance") rather than concrete actions or mundane details. The correct answer often uses metacognitive language that steps back from the action to reflect on its meaning.

Question 9

"The Vertical Forests of Milan\n\nIn 2014, the skyline of Milan, Italy, began to change in a way that surprised many observers. Two residential towers, known as Bosco Verticale (Vertical Forest), rose above the Porta Nuova district. At first, [1] Italian architect Stefano Boeri envisioned these structures, critics were skeptical. They claimed that planting trees on balconies was a gimmick that would cause structural issues. Boeri, however, believed the naysayers were totally wrong. [2]\n\nBoeri's design called for the towers to host 900 trees, 5,000 shrubs, and 11,000 floral plants. This "living facade" not only improves air quality but also regulates temperature. The vegetation, which includes oak, beech, and larch trees act [3] as a natural shield against the intense Mediterranean sun. To ensure the safety of the structure, botanists tested the wind resistance of the trees in a wind tunnel. Similarly, [4] the engineering team reinforced the concrete balconies with steel to support the immense weight of the soil.\n\nThe result is a self-sufficient ecosystem that changes colors with the seasons. In autumn, the leaves turn golden and red; in winter, they fall to let in sunlight. [5] Residents live nestled among the branches, enjoying a connection to nature rarely found in urban environments. Boeri's work has inspired similar projects in China and the Netherlands, proving that architecture and ecology can collaborate [6] to create sustainable cities. As cities grow denser, the Vertical Forest offers a blueprint for a greener future, demonstrating that nature need not be pushed, to the margins, [7] of urban life.\n\nThe project's success suggests a new path forward for urban planning. [8] By integrating living systems into high-rise buildings, architects can help reduce the carbon footprint of cities. [9]"

The writer is considering deleting the underlined sentence. Should the sentence be kept or deleted?

Kept, because it provides descriptive details that illustrate the "changes colors" mentioned in the preceding sentence. (correct answer)
Kept, because it explains why residents prefer to live in the towers during the winter.
Deleted, because it repeats information about the trees that was provided in the second paragraph.
Deleted, because it detracts from the paragraph's focus on the structural engineering of the towers.

Explanation: This is a topic development question asking whether to keep or delete a sentence. You can tell because the question stem says "The writer is considering deleting the underlined sentence. Should the sentence be kept or deleted?" You must evaluate whether the sentence serves a rhetorical purpose in the paragraph. To answer deletion questions, determine the purpose of the surrounding paragraph, then ask: Does this sentence support that purpose? Does it provide necessary detail, evidence, or development? If yes, keep it. If the sentence is redundant, off-topic, or distracting, delete it. Always read the reasoning in the answer choices carefully—both "kept" and "deleted" options will have good and bad reasons. Choice A (Kept, because it provides descriptive details...) is correct because the preceding sentence states "changes colors with the seasons," and the underlined sentence directly illustrates this claim by providing specific examples: autumn (golden and red) and winter (leaves fall). This is effective development through concrete detail. Choice B (Kept, because it explains why residents prefer winter) is incorrect reasoning—the sentence doesn't discuss residents' preferences at all; it simply describes the seasonal changes objectively. Choice C (Deleted, because it repeats information from paragraph 2) is incorrect because paragraph 2 mentions trees but doesn't describe seasonal color changes. Choice D (Deleted, because it detracts from structural engineering focus) misidentifies the paragraph's purpose—paragraph 3 focuses on the ecosystem and experience, not engineering. Remember: The ACT often includes deletion questions where you must keep valuable supporting details. When a sentence provides specific examples that illustrate a general claim made in the previous sentence, it should almost always be kept. Look for signal relationships like "For instance," or direct illustration. Pro tip: If the sentence answers the question "Like what?" or "Such as?" after reading the previous sentence, it's probably worth keeping.

Question 10

A student is writing a report about how scientists study glaciers:

To track how glaciers change over time, researchers compare satellite images taken years apart. They also place GPS stakes on the ice to measure how quickly it flows downhill. In addition, scientists drill narrow cores to examine trapped air bubbles, which can reveal past atmospheric conditions. These methods together help explain how glaciers respond to shifts in temperature and snowfall.

The student wants to add a sentence at the end of the paragraph that provides a specific example of how the data are used. Which choice best accomplishes this?

Some glaciers are so remote that researchers must travel by helicopter to reach them safely.
A glacier's surface can appear blue because dense ice absorbs some wavelengths of light more than others.
By combining GPS measurements with satellite maps, a team can calculate annual ice loss and estimate how much meltwater will enter nearby rivers. (correct answer)
Ice cores are stored in freezers so they do not melt before being analyzed in a lab.

Explanation: This question asks for a specific example of how glacier research data are used. The paragraph describes various data collection methods: satellite images, GPS stakes, and ice cores. Choice C provides the most relevant example by explaining how GPS measurements combined with satellite maps can calculate annual ice loss and estimate meltwater entering rivers - showing a concrete application of the collected data. Choices A and B discuss research logistics and ice appearance but don't show data usage. Choice D mentions ice core storage but not data application. When asked for specific examples of data use, focus on how the information leads to concrete calculations, predictions, or understanding rather than just collection methods.

Question 11

A student writes the following paragraph for a school magazine about community repair events:

At a repair café, volunteers help neighbors fix broken items instead of throwing them away. People bring everything from lamps with loose wires to jackets with torn seams, and the volunteers explain each step so visitors can learn basic skills. The events reduce waste while also making repair feel less intimidating. Many cafés keep a box of spare parts—buttons, screws, and cords—so small fixes can happen on the spot.

The student wants to add a sentence after the third sentence that elaborates on how the events make repair feel less intimidating. Which choice best accomplishes this?

Some volunteers specialize in electronics, while others are more comfortable with sewing machines and fabric.
Visitors often sit beside the volunteer working on their item, asking questions and practicing with the tools under supervision. (correct answer)
Many towns also host seasonal festivals that include music, food trucks, and art booths.
A few repair cafés operate in libraries, which may already have meeting rooms and tables available.

Explanation: This question asks you to elaborate on how repair cafés make repair feel less intimidating. The preceding sentence states that volunteers explain each step so visitors can learn basic skills, and the events make repair feel less intimidating. Choice B perfectly elaborates on this by describing how visitors sit beside volunteers, ask questions, and practice with tools under supervision - showing exactly how the intimidation factor is reduced through hands-on guidance. Choices A and D discuss volunteer specializations and café locations but don't address intimidation. Choice C about seasonal festivals is completely off-topic. When elaborating on a specific claim, choose details that directly explain the mechanism or process being described.

Question 12

A student is revising a paragraph about why libraries lend more than books. The draft reads:

[1] Many libraries now lend items such as sewing machines, Wi-Fi hotspots, and board games. [2] These collections can make expensive or specialized resources available to people who might otherwise go without them. [3] Libraries have long been places where people can find information. [4] For instance, a hotspot loan can help a student complete online homework when home internet is unreliable. [5] A sewing machine loan can help someone mend clothing instead of replacing it.

The writer wants to keep Sentence 3 but make it more clearly connected to the paragraph's main idea (lending non-book items to expand access). Which choice best revises the underlined sentence?

Libraries have long been places where people can find information, and lending practical items is another way they help communities access what they need. (correct answer)
Libraries have long been places where people can find information, especially in encyclopedias and newspapers.
Libraries have long been places where people can find information, and many are built with quiet reading rooms.
Libraries have long been places where people can find information, which is why some people prefer to buy their own books.

Explanation: This question asks you to revise a sentence to better connect it to the paragraph's main idea about libraries lending non-book items to expand access. The paragraph discusses how libraries now lend practical items like sewing machines and Wi-Fi hotspots to help people who couldn't otherwise afford them. Choice A effectively revises the sentence by maintaining the traditional information role while explicitly connecting it to lending practical items as another way libraries help communities access what they need. Choices B and C keep the information focus but fail to connect to the lending theme, while Choice D actually works against the paragraph's message about shared access. When revising for connection, ensure the sentence bridges between familiar concepts and the new idea being developed.

Question 13

PASSAGE II: Defeat from Above

¹ In late 1932, the Australian government faced a unique crisis. Following the Great Depression, struggling wheat farmers in Western Australia were besieged by a migrating force of 20,000 emus. These flightless birds, standing up to six feet tall, (13) devastated crops and destroyed fences. Desperate for help, the farmers, many of (14) whom were veterans of World War I, petitioned the government for military aid. The Minister of Defence, Sir George Pearce, agreed to deploy troops. He believed the birds would be easy targets for modern weaponry. (22)

² (15) Commanded by Major G.P.W. Meredith, the plan was simple. Two soldiers armed with Lewis machine guns and 10,000 rounds of ammunition would cull the population. The media dubbed the operation "The Great Emu War." However, the emus proved to be (16) a formidable and surprisingly strategic adversary.

³ The first engagement took place on November 2. The soldiers spotted a group of fifty emus and opened fire from a distance. The birds, (17) however, scattered instantly. They ran in every direction, making it nearly impossible to aim. Meredith noted that the emus seemed to have a leader who kept watch while the others ate, warning the flock of approaching danger. Later, the soldiers attempted to ambush a larger group of 1,000 emus near a dam. They waited until the birds were at point-blank range before firing. The gun jammed after only a dozen shots, and the flock escaped.

⁴ Meredith was astounded by the birds' resilience. "If we had a military division with the bullet-carrying capacity of these birds," he wrote, "it would face any army in the world." (18) The emus' speed and guerrilla tactics rendered the machine guns useless. By the time the operation was withdrawn, the military had expended thousands of rounds of ammunition (19) to take down only a fraction of the birds.

⁵ The "war" was a humiliation for the government. It highlighted the unpredictability of nature and the limits of military force. Ultimately, the farmers found a better solution: the bounty system. By 1934, over 57,000 bounties had been claimed, proving that local incentive was more effective than heavy artillery. The Great Emu War remains a curious footnote in history, a time when humans fought the (20) birds, it was the birds who won.

The writer is considering deleting Sentence 6 in Paragraph 1 ("He believed the birds would be easy targets..."). Should the writer do this?

Yes, because it contradicts the later information about the birds being difficult to kill.
Yes, because it repeats information from Sentence 5.
No, because it establishes the government's overconfidence, which contrasts with the actual outcome. (correct answer)
No, because it explains why machine guns were chosen over rifles.

Explanation: This is a deletion strategy question. Choice C is correct—the sentence establishes government hubris ("easy targets"), which creates irony when the emus prove formidable. This overconfidence is essential to the passage's ironic narrative structure. Choice A misunderstands—the "contradiction" is actually intentional irony, not a flaw. Choice B is wrong—Sentence 5 says troops were deployed, not that birds would be easy targets. Choice D invents a reason (explaining weapon choice) not supported by the text. Pro tip: Keep sentences that set up important contrasts or irony.

Question 14

A student is revising an informational paragraph about a town's annual marathon:

[1] The Pine Ridge Marathon draws runners of many experience levels. [2] Some athletes aim for a personal record, while others run to raise money for local charities. [3] The race begins at 7:00 a.m. near the river and ends downtown. [4] Along the route, volunteers hand out water and cheer, helping participants push through difficult miles.

Given that all choices are true, which option provides information most relevant to add after Sentence 2 to develop the idea that runners participate for different reasons?

The course includes several hills, which can make pacing difficult for first-time marathoners.
Last year, the event's fundraising teams collected over $60,000, and many runners wore shirts naming the causes they supported. (correct answer)
The town closes certain streets during the race to keep runners safe from traffic.
Some spectators bring signs and cowbells to encourage runners as they pass.

Explanation: This question asks for information that develops the idea that runners participate in the marathon for different reasons, as mentioned in Sentence 2. The paragraph contrasts runners seeking personal records with those raising money for charity. Choice B directly develops this contrast by providing specific evidence of charitable participation—fundraising teams collected over $60,000 and runners wore shirts naming their causes, showing the significance of the charity aspect. Choices A, C, and D provide general marathon information about the course difficulty, street closures, and spectator behavior, none of which develop the theme of varied participant motivations. When developing a specific idea, choose details that directly illustrate or expand upon that concept.

Question 15

A writer is drafting an informational paragraph about why some libraries lend out "seed packets" for home gardeners. Read the draft.

[1] The Oakview Library's newest collection isn't made of books at all. [2] Instead, patrons can "check out" small packets of vegetable and herb seeds. [3] The program is designed to make gardening less expensive for beginners and to encourage residents to try growing food in containers or small yards. [4] The library also offers quiet study rooms that can be reserved online. [5] At the end of the season, participants are invited to save seeds from their strongest plants and return a portion to the library for next year.

The writer wants to replace Sentence 4 with a detail that better develops the paragraph's main idea. Which choice best accomplishes that goal?

Library staff label the seed packets with planting dates and basic care tips so that first-time gardeners know when to start seeds indoors and when to move them outside. (correct answer)
The study rooms have large windows, and many students prefer to work there during the afternoon because the lighting is bright.
Some patrons visit the library to borrow novels, while others come mainly to use computers or attend community meetings.
The library's website includes a calendar of events, and the homepage features announcements about holiday hours.

Explanation: This question evaluates topic development by replacing a sentence with a detail that strengthens the main idea of why libraries lend seed packets to promote affordable gardening. The paragraph's focus is on the seed-lending program's design to help beginners grow food inexpensively and encourage community participation through returning seeds. Choice A accomplishes this goal by describing how library staff label packets with planting dates and care tips, which directly supports making gardening accessible for novices and ties into the program's educational benefits. This replacement develops the topic by adding practical details that show how the library aids users beyond just providing seeds. Choices B, C, and D fail because they introduce irrelevant information about study rooms, patron activities, or the website, diverting from the seed program's purpose. Remember, relevant details should directly support or develop the paragraph's main point, such as by providing specific examples of how a program assists users.

Question 16

A student is revising a paragraph about a school cafeteria's efforts to reduce food waste. Read the draft.

[1] Each day, the cafeteria used to throw away trays of unopened fruit and cartons of milk. [2] This year, student volunteers created a "share table" where students can place sealed items they don't plan to eat. [3] Other students can pick up those items for free, and whatever remains at the end of lunch is donated to a nearby shelter. [4] The cafeteria's walls are painted a light yellow, and the tables are arranged in long rows. [5] Since the share table began, the school has reduced its lunchtime trash by nearly a third.

The writer wants to add a sentence after Sentence 2 that explains how the share table works in a way that makes Sentence 5 more convincing. Which choice is best?

The cafeteria manager started working at the school five years ago after managing a restaurant in another town.
The shelter serves dinner to community members, and it accepts donations from several grocery stores in addition to the school.
Some students prefer to bring lunch from home, especially on days when the cafeteria serves foods they don't like.
The volunteers keep a simple tally of how many items are placed on the share table each day, which helps the school track how much food is being saved from the trash. (correct answer)

Explanation: This question tests the ability to add a sentence that explains a process in a way that makes subsequent claims more convincing, specifically regarding a school cafeteria's food waste reduction efforts. The paragraph focuses on the share table initiative, including how it allows students to donate uneaten items, benefits others, and leads to less trash overall. Choice D is best because it describes volunteers tallying items on the share table, which provides evidence of tracking saved food and strengthens the credibility of Sentence 5's claim about reduced trash by one-third. This addition develops the topic by showing a measurable aspect of the program's success. Choices B, C, and A are less effective as they discuss the shelter's operations, student lunch preferences, or the manager's background, which do not directly explain or support the waste reduction outcome. When a question asks for a sentence to make a claim convincing, focus on details that provide evidence or examples, like data tracking, to build a logical progression.

Question 17

The writer is considering adding the following phrase to the end of the preceding sentence: shimmering in the heat waves rising off the asphalt. Should the writer make this addition?

No, because it distracts from the focus on the father's navigation skills.
Yes, because it explains why the narrator's brother was sleeping.
No, because it contradicts the earlier description of the pine scent.
Yes, because it emphasizes the intense heat and sensory experience of the drive. (correct answer)

Explanation: This is a topic development question asking whether to add descriptive detail. You can tell because the question says "The writer is considering adding the following phrase" and asks "Should the writer make this addition?" You must evaluate whether the addition serves a rhetorical purpose. For questions about adding details, consider: Does the addition enhance the passage's purpose? Does it provide relevant sensory detail, evidence, or development? Does it fit the paragraph's focus, or does it distract? Read the reasoning in both "Yes" and "No" answers carefully to select the one that accurately describes the addition's effect. Choice D (Yes, because it emphasizes the intense heat and sensory experience of the drive) is correct because the phrase "shimmering in the heat waves rising off the asphalt" adds vivid sensory imagery that enhances the setting. The paragraph already establishes sensory details ("scent of pine and dust"), and this addition contributes another layer, creating a more immersive experience of the long, hot drive through Oregon backroads. Choice B (Yes, because it explains why the narrator's brother was sleeping) provides incorrect reasoning—while heat might contribute to sleepiness, that's not the primary function of this descriptive phrase, which is to enhance the sensory atmosphere of the scene. Choice C (No, because it contradicts the earlier description of pine scent) is incorrect because heat waves and pine scent can coexist—one is visual/thermal, the other is olfactory. They describe different sensory experiences and don't contradict each other. Choice A (No, because it distracts from the father's navigation skills) is incorrect because the entire paragraph establishes setting and atmosphere, not just the father's navigation. Sensory detail enriches the narrative context. Pro tip: When evaluating whether to add descriptive details, ask yourself: "Does this detail enhance the reader's experience of the scene or provide necessary information?" If yes, keep it. The ACT often includes additions that enrich sensory experience or provide concrete examples—these should usually be kept unless they're truly off-topic. Vivid details make good writing!

Question 18

A student is writing a short profile of a local museum's "sound map" exhibit. Read the draft.

[1] Visitors enter a dim room and stand before a large map of the city. [2] When a visitor taps a neighborhood on the map, speakers play a short recording captured there: a train crossing, a street market, or wind in tall grasses. [3] Curators collected the recordings over six months, visiting each site at multiple times of day. [4] The museum's gift shop sells postcards, books, and other souvenirs. [5] The exhibit encourages visitors to notice how sound can reveal a place's rhythm and daily routines.

Given that all choices are true, which sentence would be most relevant to add immediately after Sentence 3 to maintain the paragraph's focus?

Postcards in the gift shop often feature photographs of the city skyline taken from a nearby hill at sunset.
The museum building was renovated ten years ago, and the lobby now features a staircase made of polished stone.
The museum's café changes its menu seasonally and offers discounts to members on weekday mornings.
Some recordings were made with a handheld microphone inside a foam windscreen to reduce gust noise and make quieter details—like footsteps—easier to hear. (correct answer)

Explanation: This question assesses the ability to maintain paragraph focus by adding a relevant sentence that supports the description of a museum's sound map exhibit and its creation process. The paragraph centers on how the exhibit works, including the interactive map, recordings from city neighborhoods, and its goal of revealing places through sound. Choice D is most relevant because it provides a specific detail about recording techniques, like using a windscreen to capture subtle sounds, which builds on Sentence 3's mention of curators collecting recordings over time and at different hours. This enhances topic development by illustrating the care taken to ensure high-quality, immersive audio experiences. Choices B, C, and A distract by shifting to unrelated museum features like renovations, café menus, or gift shop items, which do not connect to the sound map's focus. A useful strategy is to evaluate additions based on whether they directly elaborate on the core topic, such as exhibit creation, rather than introducing tangential information about the venue.

Question 19

A student is revising a paragraph about the history of a neighborhood mural.

[1] The Eastwall Mural stretches across the side of a grocery store, depicting the neighborhood's past and present. [2] Local artists designed the mural after interviewing longtime residents about the area's changing industries. [3] The final design includes a streetcar, a factory skyline, and a modern farmers' market. [4] The paint used in the mural is water-based. [5] Since its completion, the mural has become a gathering point for walking tours and school field trips.

The writer wants to add a sentence after Sentence 3 that explains how the artists ensured the mural would represent many perspectives. Which choice best accomplishes this?

They held open studio hours where residents could review sketches, suggest additions, and vote on which symbols best captured the neighborhood's story. (correct answer)
The grocery store's owner repainted the building's trim the week before the mural was unveiled to the public.
Murals can fade over time, especially on walls that receive strong afternoon sunlight.
The artists worked mostly in the early morning to avoid painting during the hottest part of the day.

Explanation: This question tests adding a sentence to explain a process in topic development, specifically how artists ensured a mural represented multiple perspectives. The paragraph traces the history of a neighborhood mural, from design based on interviews to its community role. Choice A accomplishes this by describing open studio hours for resident input, which shows inclusive methods after Sentence 3's mention of the final design. Choices B, C, and D fail to develop this idea, instead introducing unrelated details about repainting, fading, and work schedules. When adding to explain representation, choose details that highlight collaboration, not logistics. Relevant details should directly support or develop the paragraph's main point.

Question 20

A student is writing an article about how scientists track migrating animals. The draft reads:

[1] For decades, researchers relied on leg bands and occasional sightings to learn where birds traveled. [2] Now, lightweight GPS tags can record an animal's location multiple times a day and transmit the data remotely. [3] These detailed tracks reveal not only destinations but also stopover sites where animals rest and refuel. [4] Some GPS tags are powered by tiny solar panels. [5] With better information, conservation groups can focus protection efforts on the habitats animals actually use.

The writer's goal is to emphasize how newer tracking tools provide more useful data for conservation decisions. Which choice, if substituted for Sentence 4, best accomplishes that goal?

Some researchers also study migration by observing birds from boats during early morning hours.
The tags can show that a species depends on a specific wetland for several weeks each year, helping conservationists prioritize that site for protection. (correct answer)
Many birds migrate at night, when temperatures are cooler and winds can be favorable.
NO CHANGE

Explanation: This question tests whether you can identify content that emphasizes how newer tracking tools provide more useful data for conservation decisions. The paragraph contrasts old tracking methods with new GPS technology that reveals detailed travel patterns including stopover sites. Choice B perfectly accomplishes the writer's goal by showing how GPS data reveals specific wetland dependencies, directly helping conservationists prioritize protection efforts—a concrete example of useful conservation data. The original sentence (D) about solar panels is a technical detail that doesn't connect to conservation usefulness. Choices A and C provide general information about research methods and migration patterns but don't emphasize the conservation value of the new data. Specific examples showing practical applications are generally better than technical specifications for demonstrating value.
