Excerpt from "Snoozing While Soaring"

1 Certain types of birds soar for hundreds of miles, over land, over sea—and never stop to rest. That kind of endurance seems impossible to us, since we as people need time to rest and sleep. Researchers set out to learn how birds could fly for such long distances without restorative rest. They found that for some birds, settling in for a good night's rest is not always a necessity. 2 In 2013 Felix Liechti and his research colleagues at the Swiss Ornithological Institute published results of a study about the flight habits of Alpine swifts, small birds that migrate annually between Europe and Africa. Liechti and his team fitted the birds with small electronic tags that recorded the birds' acceleration and their pitch, or angle relative to the ground. The data revealed that the birds remained completely airborne during their time in Africa, a period of over 200 days. Since all animals require sleep, the researchers inferred that the birds slept from time to time on their long journey. However, since the electronic tags recorded only movement such as gliding or flying, and not brain waves, the question of whether birds sleep during flight remained unanswered. 3 Researcher Niels Rattenborg from the Max Planck Institute for Ornithology also delved into this question. In a 2006 article Rattenborg explained that it was theoretically possible that birds could undergo a certain type of sleep while flying. Like mammals, Rattenborg explained, birds experience different types of sleep, including slow-wave sleep (SWS). Rattenborg argued that SWS during flight is plausible because SWS can happen in one hemisphere of the brain at a time, leaving half of the brain essentially awake while the other half sleeps. The eye associated with the "awake" hemisphere can still function, allowing a bird to see where it is going. Rattenborg decided that electroencephalogram (EEG) recordings of birds' brain waves would ultimately be necessary to determine whether a bird can actually sleep in flight. 4 Eventually, Rattenborg and his team were able to create an experiment to prove this theory by studying frigatebirds from the Galápagos Islands. These enormous birds are good subjects for avian-sleep research because they fly far out to sea to hunt fish. However, unlike many seabirds, they cannot land on the water to rest because the physical build of their body—long wings, poorly webbed feet, and minimal feather waterproofing—makes them unable to take off again from the surface of the water. Rattenborg concluded that they must remain in flight for up to two months at a time. 5 In an article from 2016, Rattenborg outlined the team's research methods and conclusions. The team humanely implanted EEGs on the skulls of several frigatebirds. After analyzing the EEG readings of the birds while in flight, the team determined that the frigatebirds slow-wave slept for about ten seconds at a time at points when the birds were gliding upward via warm air currents, typically the safest part of the flight. While in flight the birds slept for only 45 minutes a day, which is just enough rest for the birds to function during these long flights. They later recovered from the stress of going with very little sleep when they rested for approximately twelve hours each day back on land. 6 Using EEG recordings, Niels Rattenborg solved the puzzle of when birds sleep while traveling long distances. His evidence proved that his theory was correct, and the birds proved themselves to be the ultimate multitaskers as they manage sleep and flight at the same time.

Question 1

Excerpt from "Snoozing While Soaring"

How do paragraphs 2 and 3 work together to develop the central idea?

Paragraph 2 presents an observation that raises a scientific question, and paragraph 3 introduces a theory that attempts to answer it. (correct answer)
Paragraph 2 describes a failed experiment about bird flight, and paragraph 3 explains in detail why the experiment was unsuccessful.
Paragraph 2 focuses on the habits of one species of bird, while paragraph 3 contrasts those habits with a completely different species.
Paragraph 2 summarizes historical beliefs about how birds rest, and paragraph 3 refutes those beliefs with modern scientific data.

Explanation: When you encounter questions about how paragraphs work together, focus on identifying the specific role each paragraph plays in developing the passage's main argument or investigation. Looking at paragraph 2, you'll see it describes Liechti's study of Alpine swifts that revealed birds can stay airborne for over 200 days. The researchers inferred the birds must sleep during flight, but since their equipment only tracked movement—not brain waves—they couldn't prove when or how this sleep occurred. This creates a clear scientific question that needs answering. Paragraph 3 then introduces Rattenborg's theoretical framework for how birds might accomplish this feat. He explains that slow-wave sleep (SWS) could happen in one brain hemisphere while the other stays awake, allowing birds to sleep while maintaining flight control. However, he acknowledges that EEG recordings would be needed to prove this theory. This makes choice A correct: paragraph 2 presents an observation that raises a scientific question, and paragraph 3 introduces a theory attempting to answer it. Choice B is wrong because paragraph 2 doesn't describe a failed experiment—Liechti's study successfully revealed that birds stay airborne continuously. Choice C is incorrect since both paragraphs discuss the general phenomenon of bird sleep during flight, not contrasting different species' habits. Choice D misrepresents the content—paragraph 2 presents recent research findings, not historical beliefs, and paragraph 3 doesn't refute anything with data. Remember: when analyzing paragraph relationships, trace how each builds on the previous one—often through question-raising and question-answering patterns like this one.

Question 2

Excerpt from "Snoozing While Soaring"

The author develops the central idea of the passage by

outlining a chronological history of technological advancements in animal tracking devices from 2006 to the present day.
comparing and contrasting the flight patterns of Alpine swifts and frigatebirds to show which species is a more efficient long-distance flyer.
arguing against the initial findings of Felix Liechti's research team and proving that Niels Rattenborg's research was more scientifically accurate.
presenting a scientific mystery, detailing the progression of research and theories attempting to solve it, and culminating in the definitive experimental proof. (correct answer)

Explanation: When you encounter questions about how an author develops a central idea, focus on the overall structure and progression of the passage rather than getting caught up in specific details. This passage follows a classic scientific inquiry structure. The author begins by presenting a mystery: how do birds fly for hundreds of miles without stopping to rest? The passage then traces the evolution of research attempting to solve this puzzle. First, Liechti's 2013 study provided evidence that birds stay airborne for over 200 days but couldn't definitively prove they sleep while flying. Next, Rattenborg's 2006 theoretical work suggested slow-wave sleep could occur during flight. Finally, Rattenborg's 2016 experiment with frigatebirds provided the definitive proof using EEG recordings. Answer choice A is incorrect because the passage isn't focused on technological advancement chronology—it's about solving a specific scientific question. Choice B is wrong because the passage doesn't compare Alpine swifts and frigatebirds to determine which is more efficient; both species are simply used as research subjects. Choice C misrepresents the relationship between the studies—Rattenborg's work built upon rather than argued against Liechti's findings, and both researchers' work was scientifically valid within their scope. Choice D correctly identifies the passage's structure: mystery → progressive research attempts → definitive experimental proof. For SHSAT reading questions about textual development, always step back and consider the "big picture" organization. Ask yourself: What problem or question does the author start with, and how do they guide the reader toward resolution?

Question 3

Excerpt from "Snoozing While Soaring"

The transition from paragraph 5 to paragraph 6 serves to

shift from discussing a successful experiment to introducing a new, unanswered question for future scientific research.
move from presenting the specific data and results of the experiment to stating the broader conclusion and significance of the findings. (correct answer)
contrast the behavior of birds in the wild with their behavior in the laboratory setting described in the experiment.
provide a personal opinion from the author about the ethical implications of the research method described in paragraph 5.

Explanation: When you encounter questions about paragraph transitions, focus on analyzing what each paragraph accomplishes and how they connect. Look at the specific content and purpose of each paragraph to understand the relationship. Paragraph 5 presents detailed, specific findings from Rattenborg's frigatebird experiment: the EEG recordings showed birds slept in 10-second intervals during gliding, averaged 45 minutes of sleep daily while flying, and compensated with 12 hours of rest on land. This paragraph is packed with concrete data and experimental results. Paragraph 6 then steps back from these specific details to emphasize the broader significance: Rattenborg "solved the puzzle" of avian sleep during flight, proved his theory correct, and demonstrated that birds are "ultimate multitaskers." This paragraph synthesizes the specific findings into their larger scientific importance. Choice B correctly identifies this progression from specific experimental data to broader conclusions and significance. Choice A is wrong because paragraph 6 doesn't introduce new questions—it concludes the research and confirms the theory was proven. Choice C is incorrect because there's no contrast between wild versus laboratory behavior; the experiment studied birds in their natural flying environment. Choice D is wrong because paragraph 6 contains no personal opinions about ethics—it simply states scientific conclusions about the research's success. Strategy tip: For transition questions, always compare the main purpose of each paragraph. Look for shifts from specific to general, data to conclusions, or questions to answers. The SHSAT often tests whether you can distinguish between detailed evidence and the broader implications drawn from that evidence.

Question 4

Excerpt from "Scribe Like an Egyptian" by Hilary Wilson

1 In ancient Egypt, literacy was the key to success. However, contrary to popular belief, not all Egyptian scribes understood hieroglyphs. Many relied instead on the simpler hieratic script for the multitude of everyday documents generated by the Egyptian bureaucracy. 2 Hieroglyphs—"the Words of God"—compose a writing system with more than 1,000 distinct characters... Including both ideograms...and phonograms... [the writing system] was used in formal inscriptions on tomb and temple walls as well as on elaborate funerary papyri. For everyday purposes, however, scribes used a shorthand version of the hieroglyphic script known as hieratic, which was quicker to write and more economical of space. The two writings existed side by side for at least 2,500 years. 3 Scraps of ancient hieratic writing, mostly penned by student scribes on limestone flakes called ostraca, suggest that no matter how humble his origins, an educated Egyptian could achieve almost anything. Horemheb (d.1292 B.C.) is a good example. Born of middle-ranking parents, his scribal training led to an army career. From Scribe of Recruits... Horemheb rose through the military ranks and... was commander in chief... eventually Horemheb achieved the pinnacle of his career by becoming the last king of the 18th Dynasty... 4 But education was not available to all. Government departments and major temples supported schools, where boys commenced their training at six or seven... Boys from poorer families could only hope to be educated with support from a wealthier relative or patron, or through apprenticeship to an older scribe... This limited the scope for employment but such "on the job" training allowed apprentices to help out at home while learning.... 5 Scribal education began with the elementary principles of the hieratic script. The lowliest scribes, who trained for just five or six years, probably learned only the rudiments of the hieroglyphic script. Students were set exemplar documents and extracts from popular texts to copy... Surviving examples of copy-work sometimes include tutors' corrections added in red... 6 A schoolboy "dictionary'' of hieroglyphs with their hieratic equivalents shows that a knowledge of more than 450 signs was required for everyday writing purposes. Lessons in record-keeping and filing and labelling enabled any half-competent scribe to perform that most essential of all scribal functions: the making and updating of lists. For professions such as those of government official, priest or lawyer, a scribe would train for several more years, increasing his vocabulary to perhaps a thousand or more signs. Those with the best handwriting or drawing skills might follow the craft of creating beautifully illustrated copies of funerary texts... Others could become draughtsmen, artists or architects... Egypt's bureaucratic society depended on the skills of an army of scribes...

How do paragraphs 2 and 3 work together to develop the central idea about the importance of scribes?

Paragraph 2 focuses on the ancient discovery of scripts, while paragraph 3 details the modern process of deciphering those same scripts.
Paragraph 2 explains the extreme difficulty of hieroglyphs, and paragraph 3 argues that this difficulty prevented most people from ever becoming successful scribes.
Paragraph 2 distinguishes between two forms of writing, and paragraph 3 provides a specific example of a person who used scribal training to rise to the highest social rank. (correct answer)
Paragraph 2 describes the uses of hieratic script for everyday documents, and paragraph 3 details the specific process of training student scribes on limestone flakes.

Explanation: When you encounter questions asking how paragraphs work together, focus on identifying each paragraph's specific purpose and how they connect to support the main idea. Paragraph 2 establishes the distinction between two Egyptian writing systems: hieroglyphs (formal, complex, used for religious purposes) and hieratic script (simpler, faster, used for everyday documents). This sets up the foundation that scribes had different levels of literacy - not all needed to master the complex hieroglyphs. Paragraph 3 then illustrates this concept through Horemheb's story, showing how scribal training - even if it only involved the simpler hieratic script - could lead to extraordinary social mobility. Horemheb rose from middle-class origins to become king, demonstrating the practical power of literacy in Egyptian society. Answer C correctly identifies this relationship: paragraph 2 distinguishes the writing systems, and paragraph 3 provides concrete evidence of how scribal training led to success. Answer A is wrong because neither paragraph discusses ancient discoveries or modern deciphering processes. Answer B misrepresents both paragraphs - paragraph 2 actually explains how hieratic script made writing more accessible, and paragraph 3 shows someone who did achieve success through scribal training. Answer D incorrectly focuses on minor details (limestone flakes are mentioned briefly) rather than the paragraphs' main purposes. Strategy tip: For paragraph relationship questions, identify each paragraph's main job first, then look for how they connect - whether through contrast, example, cause-and-effect, or building an argument. Don't get distracted by minor details mentioned in the paragraphs.

Question 5

Excerpt from "Scribe Like an Egyptian" by Hilary Wilson

The passage's central idea about scribal education is developed by moving from

an analysis of student copy-work on limestone flakes to a general discussion of ancient Egyptian society and its complex social structure as a whole.
a focus on complex hieroglyphs to a focus on simpler hieratic script, showing how the simpler script eventually replaced the more complex one in Egyptian society.
a broad statement about literacy and success to a specific, high-profile example, then to the general structure of the educational system, and finally to its specialized outcomes. (correct answer)
the perspective of a young student scribe to the perspectives of a master scribe, a government official, and finally a powerful pharaoh.

Explanation: When you encounter questions about how an author develops a central idea, you need to trace the organizational pattern throughout the entire passage, not just focus on isolated details. The passage follows a clear progression that moves from general to specific and back to general. It begins with a broad statement in paragraph 1: "literacy was the key to success" in ancient Egypt. This sets up the central idea about the importance of scribal education. The author then provides a specific, compelling example in paragraph 3 with Horemheb, who rose from middle-ranking origins to become a pharaoh through his scribal training. Next, paragraphs 4-5 explain the general structure of the educational system—who could attend, how training worked, and what students learned. Finally, paragraph 6 details the specialized outcomes and various career paths available to trained scribes. Choice A is incorrect because the passage doesn't focus primarily on copy-work analysis or Egyptian social structure as a whole. Choice B misrepresents the relationship between hieroglyphs and hieratic script—the passage states they "existed side by side for at least 2,500 years," not that one replaced the other. Choice D is wrong because the passage doesn't shift between different individual perspectives; instead, it maintains an informational, third-person approach throughout. When analyzing organizational patterns, map out each paragraph's main focus and look for the logical flow between them. Authors often use this general-to-specific-to-general structure to make abstract concepts more concrete and relatable.

Question 6

Excerpt from "Winter Wheat" by Mildred Walker

The author develops the central idea by transitioning from the narrator's present anxieties about her departure (paragraphs 1-8) to

an analysis of her mother's Russian heritage and how it has influenced their family dynamics and traditions.
a detailed description of the family's farm and daily chores to emphasize all of the things she will be leaving behind.
a general flashback to her early childhood to show how her relationship with both of her parents has changed over time.
a specific memory of her father's past departure that reveals the underlying tensions and deep emotions within her family. (correct answer)

Explanation: When you encounter a question about how an author develops a central idea through structural transitions, focus on identifying the shift in content and what that shift reveals about the main theme. The passage clearly transitions from the narrator's present worries about leaving (paragraphs 1-8) to a specific flashback about her father's departure to Vermont (paragraphs 9-16). This memory isn't just any recollection—it reveals crucial family dynamics. Notice how the father calls his wife "Anna Petrovna" (using both names for the first time), how the mother responds curtly with "I'll manage," and how the departure scene is filled with tension and formality. The narrator observes that her father "seemed strange" when dressed up, and her mother stands "without smiling." This flashback illuminates the emotional complexity and underlying strains within the family that the narrator is now experiencing herself. Choice A is incorrect because while the mother may have Russian heritage (suggested by "Anna Petrovna"), the passage doesn't analyze this heritage or its influence on family traditions. Choice B is wrong because paragraphs 9-16 don't describe farm life or daily chores—they focus entirely on the departure scene. Choice C is incorrect because this isn't a general flashback about changing relationships over time; it's a specific, vivid memory of one significant departure that mirrors the narrator's current situation. Remember: when analyzing structural transitions in literature passages, look for how the shift in time or perspective deepens your understanding of the central conflict or theme, rather than just adding background information.

Question 7

Excerpt from "Winter Wheat" by Mildred Walker

1 I love Dad's way of talking that makes him seem different from other ranchers. He's lived here twenty-three years, but he still says "back East where I come from." ... but it's what Mom says that I depend on. ... Dad is always talking of going some place, not now, but next year, maybe. Mom seems to think of nothing farther away than today or perhaps yesterday or tomorrow morning. 2 ...All of a sudden, I realized that tomorrow when those beans would be ready to eat I'd be going away. It gave me a funny feeling. 3 "I'll be taking the train tomorrow night," I said aloud, more to hear it myself. 4 "We can drive you into town in the afternoon," Dad said, dropping his paper on the floor. 5 "There's no need to go to town; she can catch the train at Gotham just as well. We haven't nothing to take us into town for," Mom said. 6 "Well, we don't have to decide tonight," Dad said, but I knew he wanted to go into Clark City. It wouldn't be so flat as just seeing me go off on the train from Gotham. My going away was hard on both of them; they were so different—and I was part of them both. It made me uncomfortable to think of leaving them. 7 While I was getting ready for bed... I saw how it would be if I left from town. We'd go in right after dinner and go around to the stores... Then we'd meet... and go to the cafeteria for supper. The train stops ten minutes or so at the station in town and there are other people and excitement and you have time to wave... 8 If I left from Gotham, we'd just drive down in the truck and wait till the train came. It only stops long enough for you to get on and you hardly have time to taste the flavor of going away. 9 I sat on the bed in my pyjamas with my arms around my knees. I couldn't keep from thinking of that time Dad went back East. ... 10 Dad went all the way back to Vermont. ... It was in November and it was already dark when the train came through Gotham. Even now, I could feel how cold and dark it was. I held Mom's hand. Dad was so dressed-up he seemed strange.... 11 "I'll manage," Mom snapped back. ... 14 "Good-by, Anna Petrovna," he said, looking at Mom. I had never heard him call her by two names before. 15 "Good-by," Mom said, standing still, without smiling. 16 Then he was gone and the crossroads were darker than ever... 17 Our house seemed lonely when we came back to it. ... 20 I drank the milk sitting on a stool in front of the stove. It tasted good, but the lonely ache in my throat was still there. ... 21 "Good night, Mom," I said almost timidly, standing beside her. She seemed wrapped around in a kind of strangeness. Then she turned around and drew me to her. ... She laid her hand against my face and it felt rough and hard but firm. I dared ask her something I wanted to know. 22 "Mom, was that really your name—what Dad called you?" 23 Her voice sounded surprised. 'Why, Yelena, you know that; Anna Petrovna. You know I am born in Russia, in Seletskoe." 24 "Yes, but I didn't know your other name," I said. 25 "Anna Petrovna Webb." She pronounced it slowly. ... She laughed. Her laugh was warm and low like our kitchen, and comfortable. The house seemed natural and right again.... 26 But now that I am grown, I feel the wall of strangeness between them, more than when I was a child. I wondered how they would get along without me.

The progression from paragraph 16 ("The train light shone...") to paragraph 25 ("The house seemed natural and right again...") serves to

illustrate the stark contrast between the cold, windy weather outside the house and the physical warmth of the kitchen stove inside.
describe the physical journey from the train stop back to the family's house and barn and detail the chores that needed to be done.
reveal the narrator's growing understanding of her mother's difficult and impoverished past growing up in Russia.
trace the narrator's emotional journey from feeling the ache of loneliness to finding comfort and connection through a conversation with her mother. (correct answer)

Explanation: When you encounter questions about how a passage "progresses" or "serves to," you're being asked to trace the emotional or thematic journey through specific paragraphs, not just summarize what happens. Looking at this progression, you need to follow the narrator's emotional state from paragraph 16 to 25. The passage begins with the father's departure creating darkness and loneliness—the narrator describes a "lonely ache in my throat" and feeling "timid" around her mother, who seemed "wrapped around in a kind of strangeness." But through their conversation about the mother's Russian name and heritage, this emotional distance dissolves. The mother's "warm and low" laugh restores connection, and "the house seemed natural and right again." This traces a clear emotional arc from isolation to comfort. Answer A focuses on physical temperature contrasts, but the passage emphasizes emotional warmth, not literal warmth from the stove. Answer B describes the plot events (going home, doing chores) but misses the emotional transformation that's the real focus. Answer C mentions learning about the mother's Russian past, but the narrator already knew her mother was Russian—the revelation is just her formal name, not her "difficult and impoverished past." Answer D correctly identifies this emotional journey from loneliness to connection through meaningful conversation. On passage analysis questions, always distinguish between plot summary (what happens) and thematic progression (how emotions, relationships, or understanding develops). The SHSAT often includes plot-focused distractors to test whether you can identify the deeper literary movement.

Question 8

Excerpt from "Do Them No Harm!" by Zoa L. Swayne

1 In the moon of Ta-Yum... people from many villages of the Chopunnish Nation gathered in the Oyaip Prairie for the work and festivities of their annual camas harvest. 2 From far and near The People came.... 3 Should a stranger enter their homeland and ask, "Where are you from?" the reply was always, "We are Nee-mee-poo, The People who live here in this place." 4 It was a time of Lawtiwa-mah-ton—a time of being friends together—when The People came for this last chance to enjoy being together before the Cold Moons kept them close to their fires. ... Lawtiwa-mah-ton! It was good to be friends together. 5 As was their custom since wahk-kee-ma, a time far back beyond the memory of man, they set up their camps in the same locations their parents and grandparents had occupied before them. ... 6 Red Bear's people had traveled all summer with neighboring bands, gathering and preparing roots... Now they were at the Oyaip camp. The women worked hard... for the sharp night air brought warnings that WARM was going and COLD was coming. 7 Everyone helped in some way. Most of the men fished or hunted for meat. While many of the women dug and roasted camas, other women and older children picked and dried berries. 8 And the younger children played. They played at hunting. They played with the babies. ... They learned how to live through their play. 9 This sun, happiness, peace, and quiet blessed the Red Bear camp. All were busy with their daily tasks, until sudden cries came from the children playing by the trail. 10 —"People coming! People coming! People coming on the trail from the high mountains!" they called as they ran to their elders, who looked sharply at the figures of approaching horsemen.

The author develops the central idea in paragraphs 1 through 4 by

focusing on the history of the Chopunnish Nation and detailing their often hostile relationship with strangers who enter their homeland.
introducing a central conflict between different villages of the Chopunnish Nation who are competing for limited land and resources.
establishing the setting and cultural significance of the annual gathering, emphasizing its purpose as a time for community, work, and friendship. (correct answer)
providing a detailed list of all the specific tasks, such as digging camas and drying fish, that must be completed before the coming winter.

Explanation: When you encounter questions about how an author develops a central idea, focus on what the author is actually doing in those specific paragraphs rather than getting distracted by minor details or dramatic elements that aren't the main focus. In paragraphs 1-4, the author establishes the foundational elements of the story: the annual camas harvest gathering of the Chopunnish Nation during "the moon of Ta-Yum." The author emphasizes that this is a time when "people from many villages" come together, calling it "Lawtiwa-mah-ton—a time of being friends together." The passage stresses the cultural significance of this gathering as both a working time (harvest) and a social time (enjoying being together before winter isolation). This directly supports answer choice C. Answer choice A is incorrect because while the passage mentions strangers, there's no discussion of "often hostile relationships" - the focus is on the gathering itself, not conflicts with outsiders. Answer choice B misreads the text entirely; the villages are cooperating and gathering together peacefully, not competing for resources. Answer choice D focuses on specific tasks, but paragraphs 1-4 don't provide detailed task lists - that information comes later in the passage. For SHSAT reading questions about central idea development, always ask yourself: "What is the author's main purpose in these specific paragraphs?" Don't be misled by minor details or dramatic elements that might appear elsewhere in the passage. Focus on the primary function those paragraphs serve in the overall text structure.

Question 9

Excerpt from "Do Them No Harm!" by Zoa L. Swayne

The author builds suspense and reinforces the central idea of community from paragraph 10 to paragraph 19 by

contrasting the modern way of identifying unknown visitors with the traditional, slower methods used by The People.
describing the widespread fear and panic that spreads through the camp as they worry the approaching riders are dangerous enemies.
focusing on Red Bear's personal thoughts and anxieties as he tries to remember who the hunters could possibly be.
detailing the community's collective process of questioning, observing, and gradually identifying the approaching riders. (correct answer)

Explanation: When you encounter questions about how authors build suspense while reinforcing themes, look for specific techniques the writer uses to create tension and develop their main ideas simultaneously. In this passage, the author masterfully builds suspense by showing the entire community's collective response to the mysterious approaching riders. From paragraphs 10-19, we see a careful progression: the children first spot the riders and alert everyone, then the whole community engages in questioning ("Who can it be? What brings them here?"), observing ("Looks like hunters," "Looks like five people—not four"), and gradually identifying the visitors ("they are our four hunters! But who is the fifth person?"). This process reinforces the central theme of community because it shows how The People work together, share information, and collectively solve mysteries—emphasizing their unity and shared concern. Answer choice A is incorrect because there's no contrast between modern and traditional methods mentioned in the text. Answer choice B mischaracterizes the community's response—while there's uncertainty, the passage doesn't describe "widespread fear and panic" but rather curiosity and excitement. Answer choice C is wrong because the narrative doesn't focus on Red Bear's personal thoughts; instead, it presents the collective voice of the entire community through phrases like "questions in every mind" and group observations. Remember that suspense questions often test whether you can identify how authors use pacing and perspective. Look for how the author controls the flow of information and whose viewpoint drives the tension.

Question 10

Excerpt from "Do Them No Harm!" by Zoa L. Swayne

How does the revelation of Wat-ku-ese's identity in paragraphs 22-24 contribute to the central idea?

It transforms the event from a successful hunt into a story of homecoming and reunion, reinforcing the theme of community connection. (correct answer)
It introduces a new source of conflict by revealing that Wat-ku-ese has been away from her people and their traditions for a long time.
It explains the specific cultural rules and detailed process for how names are given within The People's culture.
It shifts the focus of the story away from the community as a whole to the individual story of one woman's difficult journey.

Explanation: When analyzing how a story element contributes to the central idea, look for how it reinforces or develops the main themes already established in the passage. The central idea here focuses on community, tradition, and the bonds that unite "The People" during their annual gathering. The revelation of Wat-ku-ese's identity perfectly reinforces the theme of community connection. What initially appears to be strangers approaching becomes a joyful reunion when the community recognizes one of their own who has returned home. This transformation from potential concern to celebration strengthens the passage's emphasis on how The People maintain their bonds across time and distance. The community immediately welcomes her with "gentle arms," food, and care, demonstrating their enduring commitment to each other. Choice A correctly identifies this shift from what could have been a hunting scene to a powerful story of homecoming that reinforces community connection. Choice B is wrong because while Wat-ku-ese has been away, the text presents this as a positive reunion rather than introducing conflict—the community welcomes her warmly. Choice C misses the mark because the passage doesn't explain detailed naming rules; it simply shows how she received her new name. Choice D is incorrect because the focus remains on the community's response to Wat-ku-ese rather than shifting to her individual journey—we learn little about her personal story. Remember: when a question asks how a plot element "contributes to the central idea," look for how it reinforces or develops themes already present rather than introducing entirely new concepts.

Question 11

Massachusetts: Lowell National Historical Park

The transition from paragraph 3 to paragraph 4 marks a shift in the development of the central idea by

changing from a historical account of nineteenth-century Lowell to a modern-day description of Lowell National Historical Park.
shifting the focus from the economic benefits of working in the mills to the various social and educational opportunities available in the city.
contrasting the positive work experiences of the first generation of "mill girls" with the negative experiences of the second generation.
moving from a description of the initial, highly regulated workforce of "mill girls" to the economic reasons for their departure and replacement. (correct answer)

Explanation: When you encounter questions about transitions between paragraphs, focus on identifying how the content and emphasis shift from one paragraph to the next. Look for changes in tone, focus, or the aspect of the topic being discussed. Paragraph 3 describes the initial experience of the "mill girls" - young women who gained economic independence by working in Lowell's mills, though they lived under strict supervision and codes of conduct. The paragraph presents this as a generally positive development, emphasizing the women's newfound independence despite the regulations. Paragraph 4 shifts dramatically by explaining why this system eventually failed. It focuses on economic pressures that led to wage cuts, deteriorating conditions, and ultimately the departure of the "mill girls" who were replaced by immigrant workers. This represents a clear transition from describing the regulated but beneficial work environment to explaining the economic factors that destroyed it. Choice A is wrong because both paragraphs discuss historical events from the 1800s - there's no shift to modern times. Choice B incorrectly suggests the focus moves to social and educational opportunities, when paragraph 4 actually discusses economic decline and worker replacement. Choice C is tempting but inaccurate because both paragraphs discuss the same generation of workers, not comparing two different generations - the shift is about changing conditions over time, not different groups. Choice D correctly identifies that the transition moves from describing the initial workforce structure and regulations to explaining the economic reasons behind the system's collapse and workforce changes. Remember: transition questions test your ability to track how an author's focus evolves between paragraphs, not just the topics discussed.

Question 12

Massachusetts: Lowell National Historical Park

1 During the first half of the 19th century, Lowell, Massachusetts, quickly transformed itself from a farm town to a bustling industrial city. In time, Lowell became a model of industry, gaining global recognition for its state-of-the-art technology, innovative canal and dam system, mill architecture... As one Scottish traveler observed... "Niagara and Lowell are the two objects I will longest remember..." 2 The Boston merchants who founded Lowell in 1821... chose to locate the town along Massachusetts's Merrimack River to take advantage of the kinetic energy offered by the Pawtucket waterfalls. Over six miles of canals powered the waterwheels of Lowell's mills, whose massive five- and six-story brick buildings dominated the city's landscape... By the 1850s, 40 textile mills employing over 10,000 workers stretched for about a mile along the river.... 3 The city's female workforce was significant in the history of Lowell. From the early to mid-1800s, women left the constricted lifestyle of small rural towns... for independent industrial city life. Most were young single Yankee girls... Although these women gained economic independence in Lowell, the mill boardinghouse keepers constantly supervised their social activities... They were expected to adhere to the strict code of conduct respecting curfew and attending church. 4 Yankee "mill girls" continued to dominate the Lowell workforce until the 1840s, when the city began to find it difficult to compete... As profits fell, the mill industry cut wages. These wage cuts, deteriorating working conditions, and long workdays led the "mill girls" to protest and organize strikes. When their demands went unheard, the women left Lowell, and immigrant groups replaced them in the workforce... 5 The immigrants replacing the Yankee "mill girls" during the 1840s were predominantly Irish Catholics... Although Lowell received an influx of Irish families during this time, the Irish were a part of the city's history from its birth... 6 Like the Irish, the French-Canadians, Greeks, Poles, Portuguese, Russian Jews, and Armenians who came to work in Lowell's mills faced long work hours, I ow wages, and poor living conditions in the city's crowded tenements. By the time Lowell's industry declined, the city had become an ethnic melting pot, where each group claimed its own distinct neighborhood... The city officially began to close down its mills in the 1920s and '30s after Lowell's outdated mills could no longer compete... Despite a brief resurgence during World War II, the city shut down its last surviving mill by the mid-1950s.

The author develops the main idea about Lowell's history by structuring the passage

as a persuasive argument, claiming that the exploitation of immigrant labor was the primary cause of the city's success and later failure.
thematically, with separate, distinct sections devoted to technology, architecture, labor relations, and immigration policy.
as a comparison and contrast between the industrial development of Lowell and that of other competing cities in New England.
chronologically, tracing the city's rise based on technology, its peak powered by different labor groups, and its eventual decline due to economic competition. (correct answer)

Explanation: When you encounter questions about passage structure, focus on how the author organizes information to develop their main ideas. Look for patterns in how events, concepts, or arguments are presented throughout the text. This passage follows a clear chronological structure that traces Lowell's complete historical arc. The author begins with Lowell's founding in 1821 and its early technological innovations using waterpower. The narrative then moves through its peak period with the "mill girls" workforce in the early-to-mid 1800s, followed by the transition to immigrant labor in the 1840s when economic pressures mounted. Finally, the passage concludes with the city's industrial decline from the 1920s through the 1950s. This time-based organization effectively shows how Lowell rose through technological advantage, thrived with different labor forces, and ultimately fell due to economic competition. Answer A is incorrect because the passage presents factual history rather than making a persuasive argument about exploitation causing success and failure. Answer B misidentifies the structure—while the passage mentions technology, labor, and immigration, these aren't organized as separate thematic sections but woven into the chronological narrative. Answer C is wrong because the passage doesn't compare Lowell to other New England cities; it focuses exclusively on Lowell's individual development. When analyzing passage structure, trace how the author moves from point to point. Time markers like dates, phrases such as "during the first half," "by the 1850s," and "until the 1840s" signal chronological organization, which is common in historical passages.

How do paragraphs 5 and 6 together refine the central idea about Lowell's immigrant workforce?

They describe the process of cultural assimilation, explaining how the various immigrant groups eventually blended into a single, unified American community.
They argue that the Irish immigrants were the most influential group in Lowell's history because they built the original canals and mills before anyone else arrived.
They show that the immigrant experience was not monolithic by detailing the initial wave of Irish immigrants and then the subsequent arrival of many other ethnic groups. (correct answer)
They focus primarily on the religious conflicts between the city's Protestant community and the Catholic and Jewish immigrants who arrived later.

Explanation: When you encounter questions asking how paragraphs "refine" a central idea, you're being tested on how authors develop and add complexity to their main points through specific details and examples. Paragraphs 5 and 6 work together to show that Lowell's immigrant experience wasn't a single, uniform story. Paragraph 5 focuses specifically on Irish Catholics who arrived during the Great Potato Famine in the 1840s, explaining their particular circumstances and how they initially faced hostility from the Protestant community that "eventually disappeared." Paragraph 6 then broadens this picture dramatically, listing multiple ethnic groups—French-Canadians, Greeks, Poles, Portuguese, Russian Jews, and Armenians—who all came to work in the mills. This progression from one specific group to many diverse groups demonstrates that immigration to Lowell was complex and varied, not a monolithic experience. Choice A is wrong because the passage emphasizes that groups maintained "distinct neighborhoods," not unified assimilation. Choice B misrepresents the timeline—Irish immigrants came in the 1840s to replace mill girls, not to build the original infrastructure. Choice D incorrectly suggests religious conflict is the primary focus, when it's only briefly mentioned regarding the Irish and quickly dismissed as temporary. The key strategy here is recognizing how authors use specific-to-general organization. When you see paragraphs that start with one detailed example and then expand to show broader patterns, they're usually demonstrating complexity or variety rather than uniformity. Look for this progression in reading comprehension passages.

Question 14

Excerpt from "Winter Wheat" by Mildred Walker

The author develops the contrast between the narrator's parents across the passage by

showing the father's clear excitement for the narrator's departure against the mother's obvious sadness and disapproval of her leaving.
juxtaposing the father's outward-looking, verbal nature with the mother's quiet, action-oriented, and inwardly focused demeanor. (correct answer)
detailing the father's fond memories of living "back East" while the mother only speaks about her difficult past in Russia.
presenting the father as the primary financial decision-maker for the family and the mother as someone who quietly follows his lead.

Explanation: When you encounter questions about character contrast, look for patterns in how characters speak, think, and behave rather than focusing on isolated details or plot events. The passage consistently shows two opposing personality types. The father is described as verbal and outward-looking—he talks about "back East where I come from" and dreams of "going some place...next year, maybe." He wants the elaborate town departure with stores, cafeteria visits, and excitement. The mother, conversely, is practical and present-focused, thinking "of nothing farther away than today or perhaps yesterday or tomorrow morning." She suggests the simple Gotham departure because "we haven't nothing to take us into town for." This fundamental difference—expansive dreamer versus grounded realist—drives their contrast throughout. Choice A misreads their emotions about the departure. Neither parent shows clear excitement or obvious disapproval; both are dealing with the difficulty of separation in their own ways. Choice C incorrectly assumes the mother is Russian based on "Anna Petrovna"—the passage never mentions Russia or details about either parent's past beyond the father being from "back East." Choice D reverses their actual dynamic. The mother makes practical decisions (like suggesting Gotham over town), while the father doesn't override her choices—he says "we don't have to decide tonight" when she disagrees. Remember: character contrast questions reward you for identifying consistent behavioral patterns across the entire passage, not for getting caught up in specific plot details or making assumptions beyond the text.

Question 15

Excerpt from "Winter Wheat" by Mildred Walker

How do paragraphs 7 and 8 contribute to the central idea about the narrator's feelings about leaving?

They show the narrator's clear preference for leaving from Gotham because it is a much quicker and more efficient way for her to depart.
They contrast the lively, communal experience of leaving from the city with the stark, lonely experience of leaving from the local stop, revealing her internal conflict. (correct answer)
They explain the practical difficulties and expenses of traveling from a rural area, focusing on the lack of reliable transportation and services.
They primarily illustrate the narrator's desire to spend more quality time with her father in Clark City before she leaves for college.

Explanation: When you encounter questions about how specific paragraphs contribute to a central idea, focus on analyzing what those paragraphs reveal about the character's emotional state and internal struggles. Paragraphs 7 and 8 present two contrasting scenarios for the narrator's departure. In paragraph 7, she imagines leaving from Clark City—a vibrant experience with shopping, meeting people, eating at a cafeteria, and having time to wave goodbye amid "other people and excitement." This creates a sense of ceremony and community around her departure. Paragraph 8 describes leaving from Gotham as stark and rushed: "just drive down in the truck and wait," with barely enough time to board and "you hardly have time to taste the flavor of going away." This contrast reveals her internal conflict between wanting a meaningful farewell and the reality of her rural circumstances. Choice A is incorrect because the narrator doesn't prefer Gotham—she actually seems drawn to the more elaborate city departure. Choice C misses the emotional focus by emphasizing practical transportation issues rather than the narrator's feelings. Choice D is too narrow, focusing only on spending time with her father rather than the broader emotional significance of how she leaves. Choice B correctly identifies that these paragraphs use contrast to reveal the narrator's conflicted feelings about departure—she's torn between the communal, celebratory experience the city would provide and the simple, isolated reality of leaving from the local stop. Remember: When analyzing how paragraphs contribute to character development, look for contrasts that reveal internal conflicts rather than just surface-level preferences or practical concerns.

Question 16

Excerpt from "Winter Wheat" by Mildred Walker

How does the final paragraph connect the narrator's past memories to her present situation?

It reveals that the narrator now feels more emotionally distant from her parents than she did when she was a young child.
It shows that her impending departure has given her a more mature understanding of the "wall of strangeness" between her parents, bringing the central conflict into focus. (correct answer)
It suggests that the narrator has decided not to leave for college after all because she is now too worried about her parents' well-being.
It concludes that her parents' relationship significantly improved after the memorable incident when her father left for Vermont.

Explanation: When you encounter questions about how a concluding paragraph connects past and present, focus on how the narrator's perspective has evolved and what new insights emerge from that maturity. The final paragraph serves as a bridge between the childhood memory of her father's departure and her current situation facing her own departure. The key phrase is "But now that I am grown, I feel the wall of strangeness between them, more than when I was a child." This shows that her adult perspective has given her deeper insight into her parents' fundamental differences—the same differences that made her uncomfortable earlier when she noted "they were so different—and I was part of them both." Her impending departure forces her to confront this central tension in her family dynamic, wondering "how they would get along without me." This brings the story's main conflict—the cultural and emotional divide between her parents—into sharp focus through her mature understanding. Choice A misinterprets the passage; she feels more distant from her parents' relationship dynamics, not emotionally distant from her parents themselves. Choice C contradicts the text—she's still planning to take the train and is considering departure logistics. Choice D completely misreads the passage; there's no indication her parents' relationship improved after the Vermont trip—if anything, the memory reinforces their ongoing "strangeness." Remember that concluding paragraphs in literary passages often reveal how a character's understanding has deepened. Look for language that contrasts past and present perspectives, especially phrases like "now that I am grown" or "I now understand."

Question 17

Massachusetts: Lowell National Historical Park

1 During the first half of the 19th century, Lowell, Massachusetts, quickly transformed itself from a farm town to a bustling industrial city.

The author develops the central idea about Lowell's workforce by

comparing the wages of female workers in Lowell's mills to the wages of male workers in other industrial New England cities.
arguing that the Yankee "mill girls" were more efficient and productive workers than the various immigrant groups who came after them.
detailing the consistent daily work schedule for all factory workers from the city's founding in the 1820s until its decline in the 1950s.
first focusing on the initial group of Yankee "mill girls," and then describing their replacement by successive waves of immigrant groups. (correct answer)

Explanation: When you encounter questions about how an author develops a central idea, you need to trace the organizational pattern and flow of information throughout the passage. The author develops the central idea about Lowell's workforce by following a clear chronological progression. The passage begins by establishing the workforce with Yankee "mill girls" in paragraphs 3-4, describing how these young women "left the constricted lifestyle of small rural towns for independent industrial city life" in the early to mid-1800s. Then the author explains their departure: wage cuts and poor conditions led them to "protest and organize strikes," and "when their demands went unheard, the women left Lowell." The passage then shifts to describe their replacements. Paragraph 5 introduces Irish Catholics as the first major immigrant group, while paragraph 6 expands this to include "French-Canadians, Greeks, Poles, Portuguese, Russian Jews, and Armenians" who faced similar challenging conditions. This creates a clear narrative arc from the original workforce to successive immigrant groups. Choice A is wrong because the passage never compares wages between male and female workers or mentions other New England cities. Choice B is incorrect because the author never argues that mill girls were more efficient than immigrants—the text focuses on working conditions, not productivity comparisons. Choice C fails because the passage doesn't provide detailed daily schedules or cover the 1950s. When analyzing text structure, look for transitional phrases and chronological markers that signal how ideas connect and build upon each other throughout the passage.

Question 18

Excerpt from "Scribe Like an Egyptian" by Hilary Wilson

How does the final paragraph (paragraph 6) bring the passage's central idea to a conclusion?

It broadens the scope from basic training to the diverse, high-level professions available to skilled scribes, reinforcing their essential role in Egyptian society. (correct answer)
It summarizes the famous career of Horemheb, who was mentioned earlier in the passage, as the ultimate example of a highly successful scribe.
It concludes that becoming a doctor or a lawyer was the most difficult and respected path for a scribe, requiring many more years of training.
It introduces the new idea that the single most important function of any scribe was the relatively simple task of making and updating lists.

Explanation: When you encounter questions asking how a final paragraph concludes a passage, focus on how that paragraph relates to and reinforces the central theme throughout the entire text. The passage's central idea is that literacy and scribal skills were crucial for success in ancient Egypt. Paragraph 6 effectively concludes this theme by showing the progression from basic scribal training (450 signs for everyday writing) to advanced specializations requiring 1,000+ signs. It demonstrates how scribes could branch into diverse high-level careers like government official, priest, lawyer, artist, or architect. The final sentence—"Egypt's bureaucratic society depended on the skills of an army of scribes"—directly reinforces their essential societal role, bringing the passage full circle. Choice A correctly identifies this broadening scope and reinforcement of scribes' importance. Choice B is wrong because paragraph 6 doesn't mention Horemheb at all—his story was confined to paragraph 3. Choice C misrepresents the content; the paragraph mentions doctors and lawyers as examples but doesn't claim they were the "most difficult and respected" paths. Choice D incorrectly suggests that list-making is presented as a new, central idea, when it's actually described as just one basic function among many more advanced skills. Remember: conclusion questions test whether you can identify how the final paragraph ties back to the main theme. Look for language that summarizes, broadens the scope, or explicitly reinforces the central argument rather than introducing entirely new concepts.

Question 19

Massachusetts: Lowell National Historical Park

How do paragraphs 1 and 2 work together to introduce the central idea of the passage?

Paragraph 1 introduces the founders of Lowell by name, and paragraph 2 details the various architectural styles of the buildings they designed.
Paragraph 1 presents a traveler's positive opinion of Lowell, and paragraph 2 provides specific evidence to challenge and refute that opinion.
Paragraph 1 establishes Lowell's significance as a model industrial city, and paragraph 2 explains the technological and geographical factors that enabled its growth. (correct answer)
Paragraph 1 compares Lowell to the natural wonder of Niagara Falls, and paragraph 2 explains why Lowell was ultimately a more important tourist destination.

Explanation: When you encounter questions about how paragraphs work together, focus on identifying each paragraph's main purpose and how they connect to support the passage's central idea. Paragraph 1 establishes Lowell's transformation from farm town to industrial powerhouse, emphasizing its global recognition and status as a "model of industry." The Scottish traveler's quote comparing Lowell to Niagara Falls reinforces its remarkable significance. Paragraph 2 then explains the concrete factors behind this success: the strategic location along the Merrimack River, the innovative use of Pawtucket waterfalls for kinetic energy, the extensive canal system, and the impressive scale of mill construction. Together, these paragraphs present Lowell's importance and then detail what made that success possible. Choice A is incorrect because paragraph 1 doesn't introduce founders by name, and paragraph 2 doesn't focus on architectural styles but rather on functional design and scale. Choice B misreads the relationship—paragraph 2 supports rather than challenges the positive view from paragraph 1 by providing evidence of Lowell's impressive infrastructure. Choice D distorts the traveler's comparison; the passage doesn't suggest Lowell was a more important tourist destination than Niagara Falls, just that both were memorable to this particular visitor. The correct answer is C because it accurately captures how paragraph 1 establishes Lowell's significance while paragraph 2 explains the technological innovation and geographical advantages that enabled this transformation. Study tip: For paragraph relationship questions, first identify what each paragraph accomplishes individually, then determine how they work together to develop the main idea.

Question 20

Excerpt from "Snoozing While Soaring"

The author develops the scientific argument in the passage by

presenting an initial study that raised a question, introducing a hypothesis to address it, and describing a subsequent, more advanced experiment that confirmed the hypothesis. (correct answer)
outlining a series of completely failed experiments and explaining how each failure eventually led researchers closer to the correct conclusion about bird sleep.
focusing on a professional rivalry between two competing scientists, Felix Liechti and Niels Rattenborg, and showing whose theory was ultimately proven superior.
explaining the complex biological makeup of migratory birds in the first half of the passage and detailing the technology used to study them in the second half.

Explanation: When you encounter questions about how an author develops an argument, focus on identifying the logical structure and flow of ideas throughout the passage. This passage follows a classic scientific inquiry pattern. It begins with Liechti's 2013 study on Alpine swifts, which provided important data showing birds could remain airborne for over 200 days. However, this study had a limitation—the electronic tags couldn't record brain waves, leaving the sleep question unanswered. Next, Rattenborg introduced his hypothesis about slow-wave sleep (SWS), theorizing that birds could sleep with one brain hemisphere while the other stayed awake. Finally, Rattenborg's team conducted a more sophisticated experiment using EEG recordings on frigatebirds, which definitively proved his hypothesis correct. Choice A correctly captures this progression: initial study → unanswered question → hypothesis → advanced experiment → confirmation. Choice B is wrong because neither study "completely failed"—Liechti's research provided valuable data, and Rattenborg's experiment succeeded. Choice C mischaracterizes the relationship between the scientists as a rivalry when they're actually building on each other's work collaboratively. Choice D incorrectly suggests the passage splits between biological makeup and technology, when the actual structure follows the scientific method chronologically. For SHSAT passages about scientific discoveries, look for this common pattern: observation or initial study → gap in knowledge → theory or hypothesis → experiment → conclusion. Recognizing this structure will help you quickly identify how authors develop scientific arguments.
