Question 1

Recent advances in materials science have produced synthetic spider silk with remarkable properties. This laboratory-created fiber mimics the natural protein structure found in orb-weaver spider silk, achieving tensile strength comparable to steel while remaining biodegradable. Engineers envision applications ranging from medical sutures to lightweight protective gear. The breakthrough emerged from studying how spiders control the molecular alignment of silk proteins during spinning, a process that occurs at ambient temperature without harsh chemicals. Researchers now aim to scale production while maintaining the material's unique combination of strength, flexibility, and environmental sustainability.
As used in the text, 'mimics' most nearly means
A. replaces the need for natural materials
B. replicates through artificial means
C. resembles in superficial appearance
D. disguises itself as something natural

Question 2

Throughout history, humans have sought to understand celestial navigation through mythology and science. Ancient Polynesian wayfinders used star paths and ocean swells to traverse thousands of miles between islands, encoding their knowledge in oral traditions passed across generations. This navigational expertise, developed over centuries of observation, enabled voyages that Western scientists once deemed impossible without modern instruments. Recent archaeological evidence from Micronesia reveals that these navigators possessed sophisticated mental maps of shifting currents and seasonal star positions, demonstrating a complex understanding of dynamic oceanic systems.
Which choice best describes the function of the underlined sentence in the text as a whole?
A. It indicates that ancient navigators were primarily motivated by proving Western scientists wrong
B. It suggests that archaeological evidence inspired the development of Polynesian navigation
C. It emphasizes the advanced nature of traditional knowledge by contrasting it with Western scientific assumptions
D. It challenges the validity of oral traditions in preserving technical knowledge

Question 3

The phenomenon of linguistic extinction affects more than communication—it erases unique worldviews embedded in grammar and vocabulary. When the last speaker of a language dies, humanity loses conceptual frameworks that may have no equivalent in surviving tongues. Linguist K. David Harrison documents how the Tuvan language contains elaborate terminology for describing horse behavior, reflecting a nomadic culture's deep relationship with these animals. Meanwhile, languages in the Amazon rainforest encode precise ecological knowledge about plant properties and animal habits. Preserving endangered languages thus means protecting irreplaceable repositories of human experience and environmental wisdom accumulated over millennia.
As used in the text, 'linguistic extinction' most nearly means
A. the gradual transformation of a language's written records
B. the evolution of a language into a new dialect over time
C. the temporary decline in the number of people learning a language
D. the permanent disappearance of a language from human use

Question 4

Text 1: Urban planners traditionally prioritize automobile traffic flow when designing city streets, measuring success through metrics like average vehicle speed and intersection wait times. This approach, dominant since the 1950s, treats pedestrians and cyclists as secondary concerns. Critics argue that car-centric design encourages sprawl and reduces walkability, ultimately undermining urban quality of life.
Text 2: Architect Jan Gehl's studies of Copenhagen demonstrate an alternative model. By prioritizing pedestrian spaces and cycling infrastructure, the city achieved higher commercial activity, improved public health outcomes, and reduced traffic congestion. Gehl's measurements focus on street-level human activity rather than vehicle throughput, showing that pedestrian-first design paradoxically improves overall urban mobility.
Based on the texts, how would Gehl (Text 2) most likely respond to the traditional planning approach described in Text 1?
A. By demonstrating that prioritizing pedestrians and cyclists actually enhances overall urban function, including mobility
B. By suggesting that automobile and pedestrian priorities should receive equal consideration in urban planning
C. By acknowledging that vehicle speed metrics remain important despite the value of pedestrian spaces
D. By arguing that pedestrian-first design inevitably increases traffic congestion in dense urban areas

Question 5

Text 1: Paleontologist Mary Schweitzer's 2005 discovery of soft tissue preserved inside a Tyrannosaurus rex fossil challenged fundamental assumptions about fossilization. Scientists had believed that proteins and cells could not survive more than 100,000 years, yet Schweitzer's team found structures resembling blood vessels and cells in 68-million-year-old bone. Initial skepticism gave way to repeated verification as similar findings emerged from other ancient specimens.
Text 2: Biochemist Matthew Collins argues that Schweitzer's findings do not represent original biological material but rather bacterial biofilms that colonized the fossils. Collins points out that some protein sequences in the samples match bacterial rather than dinosaur origins. He suggests that environmental contamination provides a more plausible explanation than the unprecedented preservation of organic matter across tens of millions of years.
Based on the texts, how would Collins (Text 2) most likely respond to the findings described in Text 1?
A. By confirming that the discoveries verify exceptional preservation conditions in certain fossils
B. By proposing that bacterial contamination offers a more scientifically plausible explanation than original tissue survival
C. By suggesting that fossilization time estimates need revision based on Schweitzer's evidence
D. By arguing that the soft tissue findings are too inconsistent to warrant serious scientific consideration

Question 6

The concept of ecological succession describes how ecosystems transform over time following disturbance. After a forest fire, for instance, pioneer species like fireweed and aspen quickly colonize bare soil, creating conditions that eventually allow shade-tolerant conifers to establish. This gradual replacement process demonstrates how ecosystems are not static entities but rather dynamic systems continuously responding to environmental changes. Ecologist Frederic Clements viewed succession as a predictable progression toward a stable climax community, while later researchers emphasized the role of random events and disturbances in preventing ecosystems from ever reaching true equilibrium.
As used in the text, 'ecological succession' most nearly means
A. the dominance of competitive species over less adaptable organisms
B. the increase in species diversity as an ecosystem matures
C. the initial colonization of an area by pioneer species after disturbance
D. the competition among species for limited environmental resources

Question 7

Behavioral economists have identified numerous cognitive biases that influence financial decision-making. The endowment effect causes people to overvalue items they already own compared to identical items they don't possess. This phenomenon explains why homeowners often price their houses higher than market value and why consumers demand more money to give up a possession than they would pay to acquire it. In experimental settings, participants randomly assigned to receive coffee mugs subsequently demanded twice as much money to sell them as other participants were willing to pay to buy identical mugs, demonstrating how mere ownership distorts perceived value.
Which choice best describes the function of the underlined sentence in the text as a whole?
A. It explains the psychological mechanism that causes the endowment effect to occur
B. It challenges the validity of experimental findings on the endowment effect
C. It illustrates the endowment effect through specific real-world examples of its influence
D. It introduces a contrasting perspective on how cognitive biases affect market prices

Question 8

Architect Maya Lin's design for the Vietnam Veterans Memorial sparked controversy upon its 1981 unveiling. Critics condemned the black granite wall as insufficiently heroic, expecting instead a traditional monument with figurative sculptures and uplifting symbolism. However, Lin's minimalist approach—listing names chronologically by date of death rather than alphabetically—creates a narrative of the war's progression while allowing visitors to trace the wall and reflect individually. The design's power emerges from this restraint: its reflective surface mirrors visitors, integrating them into the memorial and transforming observation into participation. Today, the memorial receives more visitors than any other Washington monument, vindicating Lin's unconventional vision.
Which choice best describes the function of the underlined sentence in the text as a whole?
A. It supports the argument that traditional monuments are more effective than modern designs
B. It presents a complete summary of all criticisms leveled against the memorial
C. It provides historical context for understanding the memorial's symbolic elements
D. It establishes the initial resistance to Lin's design in order to highlight its eventual acceptance

Question 9

Neuroscientist Antonio Damasio's research on emotion and decision-making overturned the classical view that rationality requires suppressing feelings. Damasio studied patients with damage to brain regions processing emotion who maintained intact logical reasoning abilities. Despite their preserved intelligence, these patients made disastrous personal and financial decisions, unable to choose between options even when one was clearly superior. Damasio concluded that emotions serve as somatic markers—physiological signals that guide decision-making by rapidly assigning value to potential choices. Far from interfering with rational thought, emotional responses provide essential information that conscious reasoning alone cannot generate, allowing us to navigate complex decisions efficiently.
Which choice best states the main idea of the text?
A. Research by Antonio Damasio demonstrates that emotional processes are necessary for effective decision-making rather than obstacles to rationality
B. Emotions generate more reliable decisions than conscious reasoning in most circumstances
C. Brain damage affecting emotional processing reveals the independence of logical reasoning from feelings
D. Patients with emotional processing deficits can still make sound decisions through purely logical analysis

Question 10

The Antikythera mechanism, discovered in a Mediterranean shipwreck in 1901, remained mysterious until recent X-ray imaging revealed its internal structure. This ancient Greek device, dating to approximately 100 BCE, contained more than thirty bronze gears arranged to predict astronomical positions and eclipses. Its sophistication rivaled that of eighteenth-century clockwork, leading historians to revise estimates of ancient technological capabilities. The mechanism could calculate the timing of the Olympic Games, track the lunar cycle, and predict planetary movements with remarkable accuracy, demonstrating that Hellenistic engineers possessed knowledge of complex gear systems centuries before such technology appeared again in medieval Europe.
Based on the text, what can most reasonably be inferred about historical understanding of ancient technology?
A. The discovery of the Antikythera mechanism revealed that ancient Greek technological knowledge was more advanced than previously assumed
B. Ancient Greek engineers deliberately concealed their most sophisticated technological achievements
C. Medieval European clockmakers had access to ancient Greek blueprints and engineering treatises
D. Most ancient civilizations possessed mechanical computing devices similar to the Antikythera mechanism

Question 11

Ecologist Daniel Janzen proposed the 'Pleistocene rewilding' hypothesis to address the ecological gaps left by North American megafauna extinctions 13,000 years ago. He argues that large herbivores shaped plant evolution through grazing pressure and seed dispersal. Species like the Osage orange, whose large fruit no living animal can effectively disperse, represent 'ecological anachronisms'—plants adapted to extinct megafauna. Janzen advocates introducing elephants and other modern megafauna as ecological proxies to restore these missing interactions. Critics contend this approach risks introducing invasive species and ignores how ecosystems have adapted during millennia without megafauna, suggesting that rewilding romanticizes a past baseline rather than preserving current ecological integrity.
According to the text, what is the main point of disagreement between Janzen and his critics regarding Pleistocene rewilding?
A. Whether restoring extinct megafauna interactions would benefit ecosystems or disrupt systems that have adapted to their absence
B. Whether megafauna extinctions were primarily caused by climate change or human hunting
C. Whether the Osage orange and similar plants evolved in response to megafauna or other factors
D. Whether modern megafauna species are genetically similar enough to extinct species to serve as proxies

Question 12

Chemist Stephanie Kwolek discovered Kevlar in 1965 while researching lightweight materials for tires at DuPont laboratories. The liquid crystalline polymer solution she synthesized appeared defective—cloudy and thin rather than clear and viscous like typical polymers. Standard protocol required discarding such solutions, but Kwolek convinced a colleague to spin the unusual fluid into fibers. The resulting material proved five times stronger than steel by weight, launching applications from bulletproof vests to fiber-optic cables. Kwolek's willingness to investigate an apparent failure exemplifies how scientific breakthroughs often emerge from exploring unexpected results rather than achieving predicted outcomes.
Which quotation from the text best supports the claim that Stephanie Kwolek's discovery required departing from standard research procedures?
A. 'The resulting material proved five times stronger than steel by weight, launching applications from bulletproof vests to fiber-optic cables.'
B. 'Standard protocol required discarding such solutions, but Kwolek convinced a colleague to spin the unusual fluid into fibers.'
C. 'Kwolek's willingness to investigate an apparent failure exemplifies how scientific breakthroughs often emerge from exploring unexpected results.'
D. 'The liquid crystalline polymer solution she synthesized appeared defective—cloudy and thin rather than clear and viscous like typical polymers.'

Question 13

Economists studying the 2008 financial crisis have debated whether regulatory failures or market dynamics were primarily responsible for the collapse. Research by economist Atif Mian shows that household debt accumulation, particularly among lower-income borrowers, created unsustainable consumption patterns that masked underlying economic weakness. As debt burdens became unmanageable, defaults cascaded through the financial system, triggering the broader crisis.
Which quotation from a researcher would best support Mian's explanation of the financial crisis?
A. 'Insufficient capital requirements for financial institutions allowed excessive risk-taking that regulators failed to adequately monitor or constrain.'
B. 'Rising household debt-to-income ratios in the years preceding 2008 created systemic fragility that ensured widespread defaults would destabilize the entire economy.'
C. 'Complex financial instruments like mortgage-backed securities obscured the true risk exposure of major banks and investment firms.'
D. 'Housing price bubbles in major metropolitan areas led to speculative investment that artificially inflated real estate values.'

Question 14

Archaeologist Sarah Parcak uses satellite imagery to identify potential excavation sites in Egypt. Her analysis of infrared wavelengths revealed subsurface features invisible to human observers, including ancient settlement patterns and buried structures. In a 2011 survey covering 3,000 square kilometers of the Nile Delta, Parcak's satellite data indicated seventeen potential pyramid sites, thousands of possible tombs, and over 3,100 previously unknown settlements. Ground surveys subsequently confirmed many locations, though excavation success rates varied depending on soil conditions and modern development.
Based on the data described in the text, which finding most strongly supports the effectiveness of Parcak's satellite archaeology method?
A. Ground surveys confirmed many locations initially identified through satellite imagery
B. Excavation success rates varied depending on soil conditions and modern development
C. Infrared satellite imagery can detect subsurface features invisible to observers on the ground
D. The survey covered 3,000 square kilometers of the Nile Delta region

Question 15

Linguist Lera Boroditsky's research examines how language structures influence spatial reasoning. She studied the Pormpuraaw Aboriginal community in Australia, whose language Kuuk Thaayorre uses cardinal directions (north, south, east, west) rather than egocentric terms (left, right, front, back) for spatial reference. When asked to arrange pictures showing temporal progression, English speakers typically order them left-to-right, while Hebrew speakers order them right-to-left, reflecting writing direction. Pormpuraaw speakers consistently arrange pictures from east to west regardless of their body orientation, demonstrating that linguistic spatial systems shape how speakers mentally organize even abstract concepts like time.
Which choice best states the main idea of the text?
A. All aspects of human cognition are fundamentally determined by the structure of one's native language
B. Different cultures arrange temporal sequences in patterns that reflect their writing system directions
C. Linguistic structures for expressing spatial relationships influence how speakers mentally organize abstract concepts
D. The Pormpuraaw language provides evidence that cardinal directions are more logical than egocentric spatial terms

Question 16

Geologists analyzing Martian rock formations have identified mineral signatures consistent with ancient hydrothermal activity. On Earth, hydrothermal vents provide energy and chemical gradients that support diverse microbial ecosystems, even in extreme environments like deep ocean trenches. The Martian deposits, found in the Gusev Crater, contain silica and sulfate minerals that on Earth typically form when hot water interacts with volcanic rock, creating chemical conditions favorable for microbial life.
Based on the text, what can most reasonably be inferred about the significance of the Martian mineral findings?
A. The minerals suggest Mars once had conditions similar to Earth environments where microbial life exists
B. The mineral composition in Gusev Crater is identical to that found near Earth's hydrothermal vents
C. The minerals prove that microbial life definitely existed on Mars during its ancient past
D. The presence of these minerals indicates that microbial life likely exists on Mars currently

Question 17

The phenomenon of bioluminescence—the production of light by living organisms—occurs across diverse taxa, from bacteria to deep-sea fish. While the underlying chemistry varies, most bioluminescent reactions involve a light-emitting molecule called luciferin and an enzyme called luciferase. In fireflies, this system produces the yellow-green flashing used for mate _____ marine organisms like dinoflagellates emit blue light when disturbed, potentially serving as a predator defense mechanism.

A. Earle has
B. Having
C. By
D. Earle

Question 21

Historian Timothy Snyder's research on twentieth-century Eastern Europe examines the region he calls the 'Bloodlands'—territories between Nazi Germany and the Soviet Union where _____ murdered fourteen million civilians between 1933 and 1945. Snyder argues that conventional Holocaust narratives have obscured the broader pattern of mass killing that included deliberate starvation, ethnic cleansing, and systematic executions across multiple states.
Which choice completes the text so that it conforms to the conventions of Standard English?
A. the regimes
B. both regimes has
C. these regimes, they
D. both regimes

Question 22

The ancient library of Alexandria, established in the third century BCE, aimed to collect all existing knowledge. Scholars estimate it housed between 400,000 and 700,000 scrolls at its _____ exact contents and the circumstances of its destruction remain subjects of historical debate, with evidence suggesting gradual decline rather than a single catastrophic event.

A. For instance,
B. In other words,
C. Nevertheless,
D. As a result,

Question 25

Agricultural scientists have long sought to reduce pesticide use while maintaining crop yields. Integrated pest management (IPM) combines biological controls, crop rotation, and targeted chemical application. ______ this approach has decreased pesticide use by 30-50% on farms implementing comprehensive IPM programs, while maintaining or even improving harvest outcomes through better soil health and beneficial insect populations.
Which choice completes the text with the most logical transition?
A. For example,
B. Consequently,
C. However,
D. Similarly,

Question 26

While researching the impact of urbanization on native plant species, a student has taken the following notes: • Cities create 'heat islands' where temperatures average 5-7°F warmer than surrounding areas. • Native plant species adapted to regional temperature ranges often struggle in urban heat islands. • Some drought-tolerant native species unexpectedly thrive in urban environments despite heat stress. • Urban soil compaction and pollution present additional challenges beyond temperature effects. • A 2022 study found that 40% of native plant species in Portland showed reduced growth in urban plots compared to rural controls.
The student wants to emphasize the complexity of urbanization's effects on native plants. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A. Native plant species adapted to specific temperature ranges struggle in cities where heat islands raise temperatures by 5-7°F.
B. While urban heat islands and soil conditions challenge many native species, with 40% showing reduced growth in one study, some drought-tolerant natives unexpectedly thrive in these warmer environments.
C. A 2022 Portland study documented that 40% of native plant species experienced reduced growth in urban locations.
D. Urban environments present multiple challenges for native plants, including heat islands, soil compaction, and pollution.

Question 27

While researching the development of early writing systems, a student has taken the following notes: • Sumerian cuneiform emerged around 3400 BCE as a system for recording economic transactions. • Egyptian hieroglyphics developed around 3200 BCE and included both phonetic and pictographic elements. • The Phoenician alphabet, created around 1050 BCE, used only phonetic symbols representing consonant sounds. • Most modern alphabets, including Greek, Latin, and Cyrillic, derive from the Phoenician system. • The Phoenician alphabet's simplicity facilitated widespread literacy compared to earlier complex writing systems.
The student wants to explain why the Phoenician alphabet had lasting historical influence. Which choice most effectively uses relevant information from the notes to accomplish this goal?
A. Most modern alphabets, including Greek, Latin, and Cyrillic, derive from the Phoenician alphabet created around 1050 BCE.
B. The Phoenician alphabet emerged centuries after Sumerian cuneiform and Egyptian hieroglyphics, which developed around 3400 BCE and 3200 BCE respectively.
C. Unlike earlier systems, the Phoenician alphabet used only phonetic symbols representing consonant sounds rather than pictographic elements.
D. The Phoenician alphabet's simplicity, using only phonetic symbols rather than complex pictographs, facilitated widespread literacy and became the foundation for most modern alphabets, including Greek, Latin, and Cyrillic.
