Passage: For centuries, the Maya of Mesoamerica tracked celestial bodies with extraordinary precision, constructing observatories aligned to the movements of Venus, the sun, and the moon. Their astronomical records, preserved in bark-paper codices, reveal sophisticated calculations of planetary cycles that rival modern measurements in accuracy. The Dresden Codex, one of the few surviving Maya texts, contains detailed Venus tables that allowed priests and astronomers to predict the planet's appearance as both morning and evening star across cycles spanning decades. This knowledge was not merely academic. Agricultural schedules, ceremonial calendars, and even military campaigns were timed according to celestial events. The crossing of Venus over the horizon, for example, was considered an auspicious moment for warfare in many Maya city-states. Scholars who have analyzed these codices argue that the integration of astronomy into governance and religion reflects a worldview in which the sky was not a passive backdrop but an active participant in human affairs. Despite the destruction of the vast majority of Maya books during the Spanish conquest, the remnants that survive continue to reshape scholarly understanding of pre-Columbian intellectual achievement. Question: What is the primary purpose of this passage?

Despite the destruction of the vast majority of Maya books during the Spanish conquest, the remnants that survive continue to reshape scholarly understanding of pre-Columbian intellectual achievement. Question: What is the primary purpose of this passage?
Correct answer: B. To describe the role of astronomical knowledge in Maya civilization and its surviving legacy
The passage covers Maya astronomical precision, its practical uses in agriculture, warfare and religion, and the partial survival of records — a broad overview of astronomy's role and legacy. A overstates: the passage says it rivals, not surpasses, modern measurement. C is wrong — destruction is mentioned only in passing. D is wrong — Greek astronomy never appears.
Q2. Passage: For centuries, the Maya of Mesoamerica tracked celestial bodies with extraordinary precision, constructing observatories aligned to the movements of Venus, the sun, and the moon.

Despite the destruction of the vast majority of Maya books during the Spanish conquest, the remnants that survive continue to reshape scholarly understanding of pre-Columbian intellectual achievement. Question: The author's description of the sky as 'not a passive backdrop but an active participant in human affairs' most likely reflects which belief?
Correct answer: B. The sky was understood as a force that actively shaped earthly decisions and events
Warfare, agriculture, and religion timed to celestial events — as described in the passage — support the idea that the sky was understood as shaping human life. B captures this. A introduces manipulation not in the passage. C directly contradicts the passage's emphasis on practical applications. D fabricates a rivalry not mentioned.

Despite the destruction of the vast majority of Maya books during the Spanish conquest, the remnants that survive continue to reshape scholarly understanding of pre-Columbian intellectual achievement. Question: Which organizational pattern best describes this passage?
Correct answer: C. General-to-specific, moving from astronomical capability to practical applications to historical context
The passage opens generally on Maya precision, narrows to the Dresden Codex, discusses practical applications, then closes with historical context about the conquest. A is wrong — no origin-to-collapse arc. B is wrong — no problem-solution structure. D is wrong — European astronomy is never discussed.

Despite the destruction of the vast majority of Maya books during the Spanish conquest, the remnants that survive continue to reshape scholarly understanding of pre-Columbian intellectual achievement. Question: Based on the passage, which of the following conclusions about Maya civilization is best supported?
Correct answer: B. Maya astronomical knowledge served both intellectual and governing functions
The passage shows astronomy informed agriculture, religious ceremonies, and military campaigns — demonstrating it was both intellectual and practically governing. B captures both dimensions. A contradicts evidence of sophisticated calculations. C contradicts the final sentence: surviving remnants 'continue to reshape scholarly understanding.' D is unsupported — priests and ceremonies are referenced throughout.
Q5. Passage: Urban tree canopies do far more than provide shade. Researchers studying metropolitan areas across multiple climate zones have documented that a ten-percent increase in canopy cover correlates with a measurable reduction in peak summer surface temperatures, a phenomenon sometimes called the urban cooling effect. Trees accomplish this through a combination of direct shading, which blocks solar radiation from reaching pavement and rooftops, and evapotranspiration, the process by which water absorbed through roots is released as vapor through leaf surfaces. Beyond temperature regulation, urban trees intercept stormwater runoff, reducing the volume of water that overwhelms drainage systems during heavy rainfall events. Their root systems stabilize soil and reduce erosion along urban waterways. Studies have also linked higher canopy cover to lower rates of respiratory illness in surrounding neighborhoods, though researchers caution that confounding variables — including income levels and proximity to highways — make it difficult to isolate the tree effect alone. Municipal governments increasingly recognize these benefits. Several major cities have adopted formal canopy-coverage targets and created dedicated funding streams to plant and maintain street trees, particularly in historically underserved neighborhoods where canopy cover has historically been lowest. Question: Which of the following best states the main idea of this passage?
Correct answer: C. Urban tree canopies provide a range of environmental and health benefits that cities are increasingly working to expand
The passage covers multiple benefits (temperature, stormwater, erosion, health) and concludes by noting cities are formally pursuing expanded coverage. C is the most comprehensive summary. A is too narrow (health is one of four benefits). B makes a prescriptive claim not in the passage. D is too narrow and overstates the cooling emphasis.
Q6. Passage: Urban tree canopies do far more than provide shade. Researchers studying metropolitan areas across multiple climate zones have documented that a ten-percent increase in canopy cover correlates with a measurable reduction in peak summer surface temperatures, a phenomenon sometimes called the urban cooling effect. Trees accomplish this through a combination of direct shading, which blocks solar radiation from reaching pavement and rooftops, and evapotranspiration, the process by which water absorbed through roots is released as vapor through leaf surfaces. Beyond temperature regulation, urban trees intercept stormwater runoff, reducing the volume of water that overwhelms drainage systems during heavy rainfall events. Their root systems stabilize soil and reduce erosion along urban waterways. Studies have also linked higher canopy cover to lower rates of respiratory illness in surrounding neighborhoods, though researchers caution that confounding variables — including income levels and proximity to highways — make it difficult to isolate the tree effect alone. Municipal governments increasingly recognize these benefits. Several major cities have adopted formal canopy-coverage targets and created dedicated funding streams to plant and maintain street trees, particularly in historically underserved neighborhoods where canopy cover has historically been lowest. Question: The passage states that researchers are cautious about linking canopy cover to respiratory health because of what concern?
Correct answer: B. Other variables, such as income levels and highway proximity, may also influence respiratory health
The passage explicitly names 'confounding variables — including income levels and proximity to highways — make it difficult to isolate the tree effect alone.' B is a direct restatement. A misreads the passage (the studies span multiple climate zones). C introduces pollen, not mentioned. D invents a time-period limitation.
Q7. Passage: Urban tree canopies do far more than provide shade. Researchers studying metropolitan areas across multiple climate zones have documented that a ten-percent increase in canopy cover correlates with a measurable reduction in peak summer surface temperatures, a phenomenon sometimes called the urban cooling effect. Trees accomplish this through a combination of direct shading, which blocks solar radiation from reaching pavement and rooftops, and evapotranspiration, the process by which water absorbed through roots is released as vapor through leaf surfaces. Beyond temperature regulation, urban trees intercept stormwater runoff, reducing the volume of water that overwhelms drainage systems during heavy rainfall events.

Municipal governments increasingly recognize these benefits. Several major cities have adopted formal canopy-coverage targets and created dedicated funding streams to plant and maintain street trees, particularly in historically underserved neighborhoods where canopy cover has historically been lowest. Question: As used in the passage, the word 'confounding' most nearly means:
Correct answer: C. Interfering with the ability to draw clear conclusions
In research methodology, confounding variables obscure the relationship between the variable studied and the outcome, making it harder to isolate the true cause. C captures this technical meaning. A mistakes the everyday sense for the research term. B fabricates a meaning tied to residents. D is the opposite — confounding variables undermine conclusions.
Q8. Passage: Urban tree canopies do far more than provide shade. Researchers studying metropolitan areas across multiple climate zones have documented that a ten-percent increase in canopy cover correlates with a measurable reduction in peak summer surface temperatures, a phenomenon sometimes called the urban cooling effect. Trees accomplish this through a combination of direct shading, which blocks solar radiation from reaching pavement and rooftops, and evapotranspiration, the process by which water absorbed through roots is released as vapor through leaf surfaces. Beyond temperature regulation, urban trees intercept stormwater runoff, reducing the volume of water that overwhelms drainage systems during heavy rainfall events. Their root systems stabilize soil and reduce erosion along urban waterways. Studies have also linked higher canopy cover to lower rates of respiratory illness in surrounding neighborhoods, though researchers caution that confounding variables — including income levels and proximity to highways — make it difficult to isolate the tree effect alone. Municipal governments increasingly recognize these benefits. Several major cities have adopted formal canopy-coverage targets and created dedicated funding streams to plant and maintain street trees, particularly in historically underserved neighborhoods where canopy cover has historically been lowest. Question: What can be inferred about historically underserved neighborhoods based on information in the passage?
Correct answer: B. They tend to have lower canopy coverage and therefore may have received fewer tree-related benefits
The passage says dedicated funding targets 'historically underserved neighborhoods where canopy cover has historically been lowest.' Lower canopy cover means fewer benefits from cooling, stormwater interception, and health effects. B follows logically. A introduces flooding risk not established in the passage. C directly contradicts the passage — these areas were previously neglected. D fabricates a geographic claim.
Q9. Passage: Urban tree canopies do far more than provide shade. Researchers studying metropolitan areas across multiple climate zones have documented that a ten-percent increase in canopy cover correlates with a measurable reduction in peak summer surface temperatures, a phenomenon sometimes called the urban cooling effect. Trees accomplish this through a combination of direct shading, which blocks solar radiation from reaching pavement and rooftops, and evapotranspiration, the process by which water absorbed through roots is released as vapor through leaf surfaces. Beyond temperature regulation, urban trees intercept stormwater runoff, reducing the volume of water that overwhelms drainage systems during heavy rainfall events. Their root systems stabilize soil and reduce erosion along urban waterways. Studies have also linked higher canopy cover to lower rates of respiratory illness in surrounding neighborhoods, though researchers caution that confounding variables — including income levels and proximity to highways — make it difficult to isolate the tree effect alone. Municipal governments increasingly recognize these benefits. Several major cities have adopted formal canopy-coverage targets and created dedicated funding streams to plant and maintain street trees, particularly in historically underserved neighborhoods where canopy cover has historically been lowest. Question: Which of the following, if true, would most weaken the case for investing in urban tree canopies in dense city centers?
Correct answer: B. The cost of maintaining large trees in confined sidewalk plots greatly exceeds the measured cooling benefit delivered
If maintenance costs far exceed the actual benefit, the investment case fails. B directly challenges the economic rationale. A supports the case by linking greenery to better health. C confirms a mechanism the passage describes and does not weaken anything. D supports the passage's concluding point about city action.
Q10. Passage: The history of printing in Korea predates the European Gutenberg press by several centuries. During the Goryeo dynasty, Buddhist monks sought ways to reproduce sacred texts more efficiently than hand-copying allowed. By the thirteenth century, artisans had developed a system of individual metal type pieces that could be arranged, inked, and pressed onto paper — then disassembled and reused for the next project. This movable metal type, known as jikji technology after the name of the oldest surviving printed book produced with it, could theoretically print any text that could be typeset. Despite this early innovation, the technology did not spread rapidly through Korean society the way printing would later transform Europe. Several historians argue that the complexity of the Korean script of the era — which used thousands of distinct Chinese characters rather than an alphabet of a few dozen letters — made typesetting impractical for most uses. A single book might require thousands of unique metal characters to be cast before printing could begin, limiting the technology largely to elite religious and governmental use. The invention of the Hangul phonetic alphabet in the fifteenth century eventually simplified the typesetting challenge, but by then the social and economic structures supporting manuscript culture were deeply entrenched. Question: What is the main idea of this passage?
Correct answer: B. Korea invented movable metal type centuries before Europe, but its spread was limited by script complexity
The passage traces both the early achievement (movable metal type predating Gutenberg) and the structural obstacle (thousands of Chinese characters limiting widespread use). B accurately captures both threads. A is not supported — monks developed the system. C overstates — Hangul simplified typesetting but was not invented specifically for that. D introduces a superiority comparison not made.
