Read the passage, then answer the question.
In the late 1800s, Thomas Edison and Nikola Tesla both worked to shape how people used electricity. Similarly, both men built devices that helped power homes and businesses, and each earned recognition for inventive talent. However, the text shows that their goals and working styles often pulled in different directions. Edison focused on making products that could be sold quickly, so he tested many small changes until something worked reliably for customers. In contrast, Tesla was drawn to big, theory-driven leaps, imagining systems that could send power more efficiently over long distances. Their disagreement became especially clear during the “War of Currents.” Edison promoted direct current (DC), which was easier to control over short distances, while Tesla supported alternating current (AC), which could travel farther with less power loss. As a result, cities faced competing electrical systems, and the debate pushed engineers to improve safety, wiring, and power stations. Even though Edison and Tesla are often portrayed as rivals, the passage suggests their shared impact came from working in the same field while approaching invention from opposite angles.
Question: What distinction does the author make between Edison and Tesla?
The author explains that Edison relied on theory while Tesla relied on repeated testing to build marketable products.
The author contrasts Edison’s practical, business-focused approach with Tesla’s more theoretical, long-distance vision for electrical systems.
The author shows that Edison and Tesla invented in completely unrelated fields, so their work never overlapped.
The author argues that the main difference is that only Tesla influenced modern electrical systems.
Explanation
This question tests analyzing how informational texts make connections among and distinctions between individuals, ideas, or events through comparisons (showing similarities), contrasts (showing differences), analogies (explaining complex through familiar), categorizations (grouping by shared properties), and cause-effect relationships. Texts establish relationships through various methods: Comparison connects by highlighting similarities ("Both Edison and Tesla revolutionized electrical technology" or "Similarly, both inventions used same basic principle"—shows what subjects share). Contrast distinguishes by emphasizing differences ("While Edison focused on practical inventions for commercial use, Tesla pursued theoretical innovations in wireless transmission"—shows divergent approaches or characteristics). The passage makes both connections and distinctions between Thomas Edison and Nikola Tesla. Connection: "Similarly, both men built devices that helped power homes and businesses, and each earned recognition for inventive talent"—shows similarity (both inventors, both in electricity, both recognized). Distinction: "Edison focused on making products that could be sold quickly, so he tested many small changes until something worked reliably for customers. In contrast, Tesla was drawn to big, theory-driven leaps, imagining systems that could send power more efficiently over long distances"—contrasts their approaches using "in contrast" to signal difference (practical/commercial vs theoretical/long-distance focus). The correct answer C accurately identifies this distinction: "The author contrasts Edison's practical, business-focused approach with Tesla's more theoretical, long-distance vision for electrical systems." This captures the key difference the passage emphasizes—Edison's focus on immediate commercial products versus Tesla's theoretical, long-range vision. Answer A is incorrect because it claims they worked in "completely unrelated fields" when the passage explicitly states both worked with electricity; Answer B reverses their approaches (Edison was practical, not theoretical); Answer D incorrectly claims only Tesla influenced modern systems when the passage suggests both had impact. Analyzing connections and distinctions requires: (1) Identify subjects being related (Edison and Tesla), (2) determine relationship type (both compared and contrasted), (3) find evidence of relationship (explicit markers: "Similarly," "In contrast"), (4) explain how relationship is established (specific comparisons made about their work in electricity, differences highlighted in their approaches), (5) understand purpose (to show how two inventors in same field took different approaches).
Read the passage, then answer the question.
The author groups energy sources into two main categories: fossil fuels and renewable energy. Fossil fuels—coal, oil, and natural gas—are described as carbon-based resources formed over millions of years. Because they take so long to form, the text explains, they are nonrenewable on a human time scale. As a result, burning them often releases large amounts of carbon dioxide and other pollutants. In contrast, renewable sources such as solar, wind, and hydroelectric power are replenished naturally and can be used repeatedly without “running out” in the same way. However, the passage notes that renewables can be variable: sunlight depends on weather and time of day, and wind depends on local conditions. By placing examples into these two groups and then listing shared traits, the author clarifies why debates about energy often involve both environmental impact and reliability.
How does the text categorize the energy sources?
It divides them into fossil fuels (nonrenewable, carbon-based) and renewables (naturally replenished but sometimes variable).
It groups them by whether they are used mostly in cities or mostly in rural areas.
It sorts them by which ones are the newest inventions.
It claims all energy sources are equally polluting and equally reliable.
Explanation
Tests analyzing how informational texts make connections among and distinctions between individuals, ideas, or events through comparisons (showing similarities), contrasts (showing differences), analogies (explaining complex through familiar), categorizations (grouping by shared properties), and cause-effect relationships. Texts establish relationships through various methods: Categorization groups items by shared characteristics ("Fossil fuels—coal, oil, natural gas—are carbon-based, non-renewable, and emit pollution; renewable sources—solar, wind, hydro—are sustainable and cleaner"—shows what items within group share and how groups differ). The passage categorizes energy sources into two main groups: "The author groups energy sources into two main categories: fossil fuels and renewable energy." For fossil fuels (coal, oil, natural gas), the text identifies shared traits: "carbon-based resources formed over millions of years...nonrenewable on a human time scale...releases large amounts of carbon dioxide and other pollutants." For renewables (solar, wind, hydroelectric), it notes they are "replenished naturally and can be used repeatedly" but "can be variable." The categorization helps readers understand energy debates by grouping sources with similar properties and contrasting the groups' environmental impact and reliability. The correct answer B accurately identifies this categorization scheme: fossil fuels (nonrenewable, carbon-based) versus renewables (naturally replenished but sometimes variable), which matches the passage's explicit grouping and characteristics. The incorrect answers misrepresent the categorization: A invents an urban/rural division not in the text, C falsely suggests grouping by invention date, and D claims all sources are equally polluting when the passage explicitly contrasts their pollution levels. Purpose of connections/distinctions: helps readers understand complex subjects by relating to familiar (analogy), see patterns across multiple items (comparison), appreciate unique features (contrast), understand cause-effect chains (historical events), organize information logically (categorization). Common mistakes: confusing comparison and contrast, missing implicit relationships (not stated but clearly present), not explaining how text establishes relationship (naming type without showing evidence), reversing directional relationships (cause-effect), focusing on superficial similarities while missing deeper connections text emphasizes.
Read the passage, then answer the question.
The passage examines two ancient river civilizations: Egypt along the Nile and Mesopotamia between the Tigris and Euphrates. Both societies, the author notes, depended on predictable water sources to farm, trade, and support growing cities. Similarly, both developed irrigation systems and organized governments to manage labor and resources. However, the author contrasts the rivers themselves. The Nile flooded in a more regular pattern, which helped Egyptian farmers plan planting seasons. In contrast, Mesopotamian rivers could flood unpredictably and sometimes violently, which made farming riskier and required stronger levees and constant repairs. The passage suggests this environmental difference influenced culture: Egyptians often described their land as stable and protected, while Mesopotamians wrote more about uncertainty and the need to control nature.
How does the author show the relationship between the two civilizations?
By presenting the civilizations as identical in environment and culture, with no meaningful differences.
By using comparison words like “both” and “similarly” to show shared dependence on rivers, and contrast words like “however” to show differences in flood patterns and their effects.
By claiming Egypt and Mesopotamia had no contact with rivers and relied only on rain.
By explaining that Mesopotamia’s stability caused the Nile to flood regularly.

Tests analyzing how informational texts make connections among and distinctions between individuals, ideas, or events through comparisons (showing similarities), contrasts (showing differences), analogies (explaining complex through familiar), categorizations (grouping by shared properties), and cause-effect relationships. Texts establish relationships through various methods: Comparison connects by highlighting similarities ("Both Edison and Tesla revolutionized electrical technology" or "Similarly, both inventions used same basic principle"—shows what subjects share). Contrast distinguishes by emphasizing differences ("While Edison focused on practical inventions for commercial use, Tesla pursued theoretical innovations in wireless transmission"—shows divergent approaches or characteristics). The passage uses both comparison and contrast to show the relationship between Egypt and Mesopotamia: "The passage examines two ancient river civilizations: Egypt along the Nile and Mesopotamia between the Tigris and Euphrates." Comparisons: "Both societies, the author notes, depended on predictable water sources to farm, trade, and support growing cities. Similarly, both developed irrigation systems and organized governments." Contrasts: "However, the author contrasts the rivers themselves. The Nile flooded in a more regular pattern...In contrast, Mesopotamian rivers could flood unpredictably and sometimes violently." The text shows how environmental differences influenced culture: "Egyptians often described their land as stable and protected, while Mesopotamians wrote more about uncertainty." The passage uses explicit transition words ("Both," "Similarly," "However," "In contrast") to signal connections and distinctions. The correct answer A accurately identifies the text's use of comparison words to show shared river dependence and contrast words to show different flood patterns and effects. The incorrect answers misrepresent the text: B falsely claims the civilizations had no river contact, C denies the differences the passage explicitly describes, and D invents an impossible causal claim about Mesopotamia causing Nile floods. Explicit vs implicit: explicit relationships include transition words or direct statements ("The two approaches differ in..."), implicit relationships require reader to recognize connection from presented information (listing three conservation efforts without saying "these are all types of environmental protection"—reader infers category).
Read the passage, then answer the question.
The passage connects the Industrial Revolution to rapid urbanization by showing a chain of cause and effect. First, new machines and factories increased production, so factory owners needed many workers in one place. Because of this demand, rural families who had once depended on farming began moving to cities to find steady wages. As a result, cities grew faster than their housing, sanitation systems, and transportation could handle. The author adds that crowded neighborhoods and polluted water were not random problems; they were linked to the speed of growth and the lack of planning. Finally, the passage notes that these challenges pushed city governments to build sewers, expand public transit, and create health regulations.
How does the text show that the Industrial Revolution led to urban problems?
It compares cities to farms to show they were basically the same.
It argues that urban problems existed first and therefore caused factories to be built.
It lists city problems but avoids explaining why they happened.
It describes a cause-and-effect sequence: factories created jobs, jobs drew people to cities, and fast growth strained housing and sanitation.
Explanation
Tests analyzing how informational texts make connections among and distinctions between individuals, ideas, or events through comparisons (showing similarities), contrasts (showing differences), analogies (explaining complex through familiar), categorizations (grouping by shared properties), and cause-effect relationships. Texts establish relationships through various methods: Cause-effect connects events/ideas showing one led to another ("The Industrial Revolution created factory jobs, which attracted rural workers to cities, causing rapid urbanization"—links cause to consequence). The passage explicitly traces a cause-and-effect chain from the Industrial Revolution to urban problems: "The passage connects the Industrial Revolution to rapid urbanization by showing a chain of cause and effect. First, new machines and factories increased production, so factory owners needed many workers in one place. Because of this demand, rural families who had once depended on farming began moving to cities to find steady wages. As a result, cities grew faster than their housing, sanitation systems, and transportation could handle." The text uses causal language ("Because of this demand," "As a result") to show how each event led to the next: factories→need for workers→rural migration→rapid city growth→urban problems. The passage emphasizes these were not random but "linked to the speed of growth and the lack of planning." The correct answer B accurately identifies this cause-and-effect sequence showing how factories created jobs, which drew people to cities, straining infrastructure. The incorrect answers misrepresent the causal relationship: A reverses causation claiming urban problems caused factories, C denies the explanation exists when it's explicitly stated, and D introduces an irrelevant comparison to farms. Analyzing connections and distinctions: (1) Identify subjects being related (which individuals, ideas, or events does text discuss?), (2) determine relationship type (compared? contrasted? linked causally? categorized? explained through analogy?), (3) find evidence of relationship (explicit markers: "similarly," "in contrast," "as a result," "like"; or implicit—items presented together suggesting connection), (4) explain how relationship is established (specific comparisons made, differences highlighted, causal chain shown, analogy structure explained), (5) understand purpose (why does author connect these?—to show pattern, explain complexity, demonstrate causation, group related concepts).
Read the passage, then answer the question.
The author explains the difference between a growth mindset and a fixed mindset by contrasting the way each responds to difficulty. A student with a growth mindset, the passage says, believes ability can improve through practice, feedback, and new strategies. Therefore, when the student makes mistakes, the mistakes are treated as information about what to work on next. In contrast, a student with a fixed mindset believes ability is mostly unchangeable. As a result, challenges may feel like threats, and the student might avoid hard tasks to prevent looking “bad” at something. The author uses signal words like “therefore,” “in contrast,” and “as a result” to show that beliefs lead to different behaviors.
What distinction does the author make between a growth mindset and a fixed mindset?
A growth mindset views ability as improvable and uses mistakes to learn, while a fixed mindset treats ability as unchangeable and may avoid challenges.
A fixed mindset is caused by practicing too much, while a growth mindset is caused by practicing too little.
A growth mindset avoids feedback, while a fixed mindset seeks out criticism.
Both mindsets respond to difficulty in exactly the same way.

Texts establish relationships through various methods: Contrast distinguishes by emphasizing differences ("While Edison focused on practical inventions for commercial use, Tesla pursued theoretical innovations in wireless transmission"—shows divergent approaches or characteristics). Cause-effect connects events/ideas showing one led to another ("The Industrial Revolution created factory jobs, which attracted rural workers to cities, causing rapid urbanization"—links cause to consequence). The passage contrasts growth and fixed mindsets by showing how different beliefs lead to different behaviors: "The author explains the difference between a growth mindset and a fixed mindset by contrasting the way each responds to difficulty." For growth mindset: "believes ability can improve through practice, feedback, and new strategies. Therefore, when the student makes mistakes, the mistakes are treated as information about what to work on next." For fixed mindset: "believes ability is mostly unchangeable. As a result, challenges may feel like threats, and the student might avoid hard tasks to prevent looking 'bad' at something." The text uses causal language ("Therefore," "As a result") to show beliefs determine behaviors, explicitly stating it uses these "signal words...to show that beliefs lead to different behaviors." The correct answer B accurately captures this distinction: growth mindset views ability as improvable and uses mistakes to learn, while fixed mindset treats ability as unchangeable and may avoid challenges. The incorrect answers misrepresent the distinction: A reverses which mindset seeks feedback, C denies the differences the passage explicitly describes, and D invents false causal claims about practice amounts. Recognizing relationship types: comparison emphasizes what's shared (both/similarly/likewise), contrast emphasizes differences (while/however/unlike), analogy uses structure "A is to B as X is to Y" or "just as...so too" making unfamiliar familiar, categorization groups items showing within-group similarities and between-group differences, cause-effect uses "because/led to/as a result" showing one thing produced another, sequential uses "first...then...finally" or temporal markers showing progression.
Read the passage, then answer the question.
To trace how major civil rights events built on one another, the author uses a clear timeline. First, Brown v. Board of Education (1954) is presented as a legal turning point because it declared school segregation unconstitutional. Following that decision, the Montgomery Bus Boycott (1955–56) is described as a community action that demonstrated the power of organized, nonviolent protest. Subsequently, the passage explains, national attention and continued activism increased pressure on lawmakers. Finally, the Civil Rights Act of 1964 is shown as a federal response that outlawed segregation in many public places and banned employment discrimination. By using words like “first,” “following,” and “finally,” the author emphasizes how earlier steps created momentum for later change.
How does the text connect Brown v. Board of Education to the Civil Rights Act of 1964?
It argues that the Civil Rights Act happened before Brown v. Board of Education.
It shows a sequence in which the court ruling helped inspire later activism and pressure that contributed to national legislation.
It claims the events were unrelated and occurred in different centuries.
It suggests the Montgomery Bus Boycott ended the need for any further laws.
Explanation
Tests analyzing how informational texts make connections among and distinctions between individuals, ideas, or events through comparisons (showing similarities), contrasts (showing differences), analogies (explaining complex through familiar), categorizations (grouping by shared properties), and cause-effect relationships. Texts establish relationships through various methods: Sequential connection shows progression ("Brown v Board ended legal school segregation; this legal victory encouraged further challenges, leading to Montgomery Bus Boycott, then Civil Rights Act"—events build on each other). The passage uses temporal markers and sequential language to connect civil rights events: "To trace how major civil rights events built on one another, the author uses a clear timeline. First, Brown v. Board of Education (1954) is presented as a legal turning point...Following that decision, the Montgomery Bus Boycott (1955–56) is described...Subsequently, the passage explains, national attention and continued activism increased pressure on lawmakers. Finally, the Civil Rights Act of 1964 is shown as a federal response." The text explicitly uses "First," "Following," "Subsequently," and "Finally" to show how earlier events created momentum for later ones, with the passage stating the author "emphasizes how earlier steps created momentum for later change." The correct answer A accurately identifies this sequential connection where the court ruling inspired later activism that contributed to national legislation. The incorrect answers misrepresent the timeline: B reverses chronology claiming the Act preceded Brown, C falsely suggests the boycott ended the need for laws, and D denies any connection between events that the passage explicitly links. Recognizing relationship types: comparison emphasizes what's shared (both/similarly/likewise), contrast emphasizes differences (while/however/unlike), analogy uses structure "A is to B as X is to Y" or "just as...so too" making unfamiliar familiar, categorization groups items showing within-group similarities and between-group differences, cause-effect uses "because/led to/as a result" showing one thing produced another, sequential uses "first...then...finally" or temporal markers showing progression. Purpose of connections/distinctions: helps readers understand complex subjects by relating to familiar (analogy), see patterns across multiple items (comparison), appreciate unique features (contrast), understand cause-effect chains (historical events), organize information logically (categorization).
Read the passage, then answer the question.
In the late 1800s, Thomas Edison and Nikola Tesla both worked with electricity, and the text points out that each held many patents and helped shape modern power systems. Similarly, both relied on careful observation and repeated testing to improve their inventions. However, the author draws a clear contrast in their goals. Edison focused on building devices that could be sold quickly and used safely in homes and businesses, so he organized teams and created companies to produce his designs. In contrast, Tesla spent more time imagining bold new possibilities, such as long-distance wireless transmission, even when the technology and funding were not yet ready. The passage suggests that these different approaches affected their public reputations: Edison became known as a practical business-minded inventor, while Tesla became known as a visionary whose ideas sometimes arrived “ahead of their time.”
Which distinction does the author make between Edison and Tesla?
The author contrasts Edison’s focus on market-ready, practical inventions with Tesla’s focus on ambitious theoretical ideas like wireless power.
The author claims Edison avoided testing, while Tesla relied only on trial and error.
The author argues Tesla copied Edison’s inventions and improved them.
The author says Edison worked mostly alone, while Tesla always worked in large teams.

Contrast distinguishes by emphasizing differences ("While Edison focused on practical inventions for commercial use, Tesla pursued theoretical innovations in wireless transmission"—shows divergent approaches or characteristics). The passage makes both connections and distinctions between Thomas Edison and Nikola Tesla. Connection: "both worked with electricity, and the text points out that each held many patents and helped shape modern power systems. Similarly, both relied on careful observation and repeated testing"—shows similarities (both inventors, both in electricity, both used scientific method). Distinction: "Edison focused on building devices that could be sold quickly and used safely in homes and businesses" while "Tesla spent more time imagining bold new possibilities, such as long-distance wireless transmission"—contrasts their approaches using "In contrast" to signal difference (practical/commercial vs theoretical/visionary focus). The correct answer B accurately identifies this distinction between Edison's market-ready, practical focus versus Tesla's ambitious theoretical ideas, which the passage explicitly states affected their public reputations. The incorrect answers misrepresent the text: A falsely claims Edison worked alone when passage says he "organized teams," C invents a copying claim not in the text, and D contradicts the passage which says both used "repeated testing." Analyzing connections and distinctions: (1) Identify subjects being related (which individuals, ideas, or events does text discuss?), (2) determine relationship type (compared? contrasted? linked causally? categorized? explained through analogy?), (3) find evidence of relationship (explicit markers: "similarly," "in contrast," "as a result," "like"; or implicit—items presented together suggesting connection), (4) explain how relationship is established (specific comparisons made, differences highlighted, causal chain shown, analogy structure explained), (5) understand purpose (why does author connect these?—to show pattern, explain complexity, demonstrate causation, group related concepts).
Read the passage, then answer the question.
The author compares two ways scientists study Earth’s past climate: ice cores and tree rings. Both, the passage explains, act like natural records because they preserve clues over time. Similarly, both methods require careful measurement and comparison with modern data. However, the author highlights an important difference in what each record captures best. Ice cores, drilled from glaciers, can trap tiny bubbles of ancient air, so they reveal past greenhouse gas levels and can stretch back hundreds of thousands of years. In contrast, tree rings usually cover a shorter time span, but they can show year-by-year changes in local conditions such as rainfall and temperature. By placing “both” and “however” side by side, the passage makes it clear that the tools are connected by purpose but separated by what they measure most precisely.
How does the author connect and distinguish ice cores and tree rings?
The author states ice cores and tree rings measure the same information in the same way.
The author explains that both are natural climate records, but ice cores reveal long‑term atmospheric gases while tree rings show detailed year-by-year local changes.
The author says both are human-made instruments, but only ice cores can be used outdoors.
The author argues tree rings are more useful because they contain ancient air bubbles.

Texts establish relationships through various methods: Comparison connects by highlighting similarities ("Both Edison and Tesla revolutionized electrical technology" or "Similarly, both inventions used same basic principle"—shows what subjects share). Contrast distinguishes by emphasizing differences ("While Edison focused on practical inventions for commercial use, Tesla pursued theoretical innovations in wireless transmission"—shows divergent approaches or characteristics). The passage makes both connections and distinctions between ice cores and tree rings as climate research tools. Connection: "Both, the passage explains, act like natural records because they preserve clues over time. Similarly, both methods require careful measurement and comparison with modern data"—establishes their shared purpose and methodology. Distinction: "However, the author highlights an important difference in what each record captures best. Ice cores...can trap tiny bubbles of ancient air, so they reveal past greenhouse gas levels and can stretch back hundreds of thousands of years. In contrast, tree rings usually cover a shorter time span, but they can show year-by-year changes in local conditions." The text uses "both" and "similarly" for connections, "however" and "in contrast" for distinctions, explicitly stating it "makes it clear that the tools are connected by purpose but separated by what they measure most precisely." The correct answer B accurately identifies both the connection (natural climate records) and distinction (ice cores show long-term atmospheric gases, tree rings show detailed local changes). The incorrect answers mischaracterize the relationship: A invents false claims about human-made instruments and outdoor use, C reverses which method contains air bubbles, and D denies the differences the passage explicitly describes. Explicit vs implicit: explicit relationships include transition words or direct statements ("The two approaches differ in..."), implicit relationships require reader to recognize connection from presented information (listing three conservation efforts without saying "these are all types of environmental protection"—reader infers category).
Read the passage, then answer the question.
The author compares two ways communities respond to water shortages: building dams and promoting water conservation. Both approaches, the text notes, aim to ensure people have enough water for drinking, farming, and industry. Similarly, each can require planning and cooperation across many groups. However, the author highlights a key contrast. Dams increase supply by storing water, but they can flood habitats and change river ecosystems. In contrast, conservation reduces demand through actions like fixing leaks, using drought-tolerant landscaping, and installing efficient appliances. The author uses signal words such as “both,” “similarly,” and “however” to show shared purpose first and then separate the strategies by their different methods and side effects.
Question: How does the author show the relationship between building dams and promoting conservation?
By explaining that conservation caused dams to fail and therefore should replace all reservoirs.
By using comparison words to show they share the goal of addressing shortages, then using contrast words to show one increases supply while the other reduces demand.
By arguing that dams and conservation are identical and have the same environmental impacts.
By describing only dams in detail and never mentioning conservation methods.
Explanation
This question tests analyzing how informational texts make connections among and distinctions between individuals, ideas, or events through comparisons (showing similarities), contrasts (showing differences), analogies (explaining complex through familiar), categorizations (grouping by shared properties), and cause-effect relationships. The passage systematically compares and contrasts two water management strategies using explicit comparison and contrast language to show both shared purpose and different methods. Connection through comparison: 'Both approaches, the text notes, aim to ensure people have enough water' and 'Similarly, each can require planning and cooperation'—establishes shared goal of addressing water shortages. Distinction through contrast: 'However, the author highlights a key contrast'—dams 'increase supply by storing water' but 'can flood habitats,' while 'In contrast, conservation reduces demand' through efficiency measures. The text explicitly uses signal words ('both,' 'similarly,' 'however,' 'in contrast') to guide readers through the relationship. The correct answer A accurately captures this dual relationship—the author uses comparison words to show shared goal of addressing shortages, then contrast words to show one increases supply while the other reduces demand, precisely matching the text's structure of establishing similarity before highlighting methodological differences. The incorrect answers misrepresent the relationship: B falsely claims they're identical, C invents a causal claim about conservation causing dam failure, D claims only dams are discussed when both strategies receive detailed treatment. Analyzing connections and distinctions requires: (1) identifying comparison markers ('both,' 'similarly'), (2) identifying contrast markers ('however,' 'in contrast'), (3) understanding shared elements (addressing water shortage goal), (4) recognizing differences (supply increase vs. demand reduction), (5) seeing how text structures the relationship (similarity first, then contrast).
Read the passage, then answer the question.
The author examines two explorers: Zheng He of Ming China and Christopher Columbus of Spain. Both led major sea voyages that connected distant regions, and the text points out that each traveled with ships, crews, and supplies that required careful planning. Similarly, both voyages increased knowledge of geography for their societies. However, the author emphasizes different purposes and outcomes. Zheng He’s expeditions are described as state-sponsored missions meant to display power, build trade relationships, and collect tribute, and they did not lead to long-term colonies. In contrast, Columbus’s voyages are portrayed as opening the door to European colonization in the Americas, which brought lasting settlement and major changes for Indigenous peoples. The passage uses “both” to establish similarity and “however/in contrast” to highlight differences in goals and impact.
Question: How does the text connect and distinguish Zheng He and Columbus?
It argues Columbus copied Zheng He’s exact routes and therefore had the same outcomes.
It claims neither explorer traveled by sea, so their journeys had little to do with navigation.
It compares them by noting both led important voyages, but contrasts them by showing Zheng He’s missions focused on diplomacy/trade display while Columbus’s voyages led to colonization and settlement.
It categorizes both explorers as mythological characters whose stories are not based on real events.
Explanation
This question tests analyzing how informational texts make connections among and distinctions between individuals, ideas, or events through comparisons (showing similarities), contrasts (showing differences), analogies (explaining complex through familiar), categorizations (grouping by shared properties), and cause-effect relationships. The passage both connects and distinguishes Zheng He and Columbus through explicit comparison and contrast language, establishing similarities before highlighting crucial differences in purpose and impact. Connections: 'Both led major sea voyages that connected distant regions,' both required 'ships, crews, and supplies that required careful planning,' and 'Similarly, both voyages increased knowledge of geography'—establishes them as comparable maritime explorers. Distinctions: 'However, the author emphasizes different purposes and outcomes'—Zheng He's expeditions were 'state-sponsored missions meant to display power, build trade relationships, and collect tribute' that 'did not lead to long-term colonies,' while 'In contrast, Columbus's voyages are portrayed as opening the door to European colonization' with 'lasting settlement and major changes for Indigenous peoples.' The correct answer B accurately captures this dual relationship—the text compares them as leaders of important voyages but contrasts Zheng He's diplomatic/trade display missions with Columbus's voyages that led to colonization and settlement, precisely matching the passage's comparison-contrast structure. The incorrect answers misrepresent the relationship: A falsely claims neither traveled by sea, C incorrectly states Columbus copied Zheng He's routes, D absurdly categorizes them as mythological. Analyzing connections and distinctions requires: (1) identifying comparison markers ('Both,' 'Similarly'), (2) identifying contrast markers ('However,' 'In contrast'), (3) recognizing shared elements (major sea voyages, geographic knowledge expansion), (4) understanding key differences (diplomatic display vs. colonization outcomes), (5) grasping historical significance of distinction (temporary influence vs. permanent settlement).
