Text 1
Proponents of "assisted migration"—deliberately moving plant species to higher latitudes or elevations to escape warming climates—argue that active human intervention is necessary to prevent mass extinctions. Ecological researcher Dr. Aris Thorne contends that natural migration rates of slow-growing tree species are far outpaced by current climate shifts. Without targeted relocation programs, key forest species face severe habitat fragmentation and ultimate decline. Thorne suggests that the risks of inaction far outweigh the potential ecological disruptions of introducing species to new ranges.

Text 2
Ecologist Dr. Elena Vance urges caution regarding assisted migration, emphasizing the unpredictability of novel ecosystems. Vance points out that introducing non-local tree species can lead to unforeseen competition with native flora and alter soil chemistry, potentially harming established communities. Furthermore, she argues that focusing resources on relocations diverts critical funding from preserving existing habitats. Rather than manually redistributing species, Vance suggests, conservationists should prioritize reinforcing native habitats and connecting corridors to facilitate self-directed migration.

Based on the texts, how would Vance (Text 2) most likely characterize Thorne’s claim in Text 1 that the risks of inaction outweigh the potential disruptions of introducing species to new ranges?

For decades, planetary scientists hypothesized that Earth's water was delivered primarily by carbonaceous chondrite meteorites during the planet's late accretion phase, pointing to isotopic similarities between the water on Earth and in these meteorites. Recently, however, researchers analyzing samples from the asteroid Itokawa discovered that solar wind implanting hydrogen ions into surface minerals could represent a significant, previously overlooked source of water. While this new mechanism explains how water could form on dry space rocks, it has not yet supplanted the meteorite delivery model. Instead, scientists are now exploring how both processes may have concurrently contributed to Earth's early oceans.

Which choice best describes the overall structure of the text?

In 1903, the Wright brothers conducted the first sustained, controlled flight of a powered aircraft near Kitty Hawk, North Carolina. Although many contemporaries doubted the feasibility of heavier-than-air flight, this historic achievement ultimately ________ the field of aviation and paved the way for modern aerospace engineering.

Which choice completes the text so that it conforms to the conventions of Standard English?

Review the passage below. Identify the transition word or phrase that should be inserted in the blank to establish the correct logical relationship.

While researching ancient Mediterranean merchant ships, a student took the following notes:

* The *Kyrenia* shipwreck represents a Greek merchant vessel that sank in the 4th century BCE.
* The *Kyrenia* vessel was relatively small, measuring approximately 14 meters in length.
* The *Madrague de Giens* shipwreck represents a Roman merchant vessel that sank around 75–60 BCE.
* The *Madrague de Giens* vessel was a large cargo ship, measuring approximately 40 meters in length.

The student wants to contrast the lengths of the two vessels. Which choice most effectively uses information from the given notes to accomplish this goal?

Text 1
Archaeologist Maria Reiche argued that the Nazca Lines in Peru were created primarily as an astronomical calendar. She proposed that the giant geoglyphs—depicting animals, plants, and geometric patterns—marked the rising and setting points of key stars and constellations on the horizon. According to Reiche, these markers served a practical agricultural purpose, helping the Nazca people determine optimal planting and harvesting times by tracking seasonal changes through celestial alignments.

Text 2
Anthropologist Anthony Aveni has analyzed the Nazca geoglyphs using modern archaeoastronomical mapping software. Aveni’s team systematically measured the alignments of hundreds of lines against stellar movements over several centuries. Their findings revealed that only a small, statistically insignificant fraction of the lines align with astronomical phenomena. Aveni suggests instead that the lines were pathways walked during water-related religious rituals, as many lines run parallel to underground aqueducts or lead to ritual sites associated with water offerings.

Based on the passages, how would Aveni (Text 2) most likely respond to Reiche’s hypothesis (Text 1) regarding the primary function of the Nazca Lines?

For decades, archaeologists studying ancient Maya civic centers focused primarily on their visual prominence and spatial alignment with astronomical events. However, recent studies in archaeoacoustics suggest that the architectural layouts of Mayan plazas were also intentionally designed for auditory performance. Researchers measuring sound propagation in plazas like those at Palenque found that the stuccoed limestone walls and step-terrace structures functioned as passive amplifiers, projecting spoken words from elevated central platforms across wide, open areas with minimal distortion. This acoustic engineering enabled political and religious leaders to communicate directly with large assemblies of citizens who stood far from the stage, suggesting that these public spaces were designed as much for auditory participation as they were for visual spectacle.

Which choice best states the main idea of the text?

While preparing a presentation on ancient Roman history, a student takes the following notes:
* The Aqua Appia, Rome's first aqueduct, was built underground to protect the water supply from hostile forces during war.
* The Aqua Anio Vetus was constructed forty years later to meet the water demands of Rome's expanding population.
* The construction of the Aqua Anio Vetus was funded entirely by spoils taken from defeated military adversaries.
* Both aqueducts utilized gravity to transport water from distant springs into the city.

The student wants to support the claim that military conflicts influenced the design or funding of Rome's earliest aqueducts. Which choice most effectively uses information from the given notes to accomplish this goal?

While preparing a presentation on avian evolution, a student takes the following notes:
* *Microraptor gui* was a dromaeosaurid dinosaur that possessed asymmetric flight feathers on both its forelimbs and hindlimbs.
* The "ground-up" (cursorial) hypothesis proposes that flight evolved in running animals, which requires high-speed running on flat ground to generate lift.
* The "trees-down" (arboreal) hypothesis proposes that flight evolved in tree-dwelling animals that glided from elevated perches.
* Biologist Dr. Sarah Werning used aerodynamic modeling to study the effects of *Microraptor*'s long hindlimb feathers.
* The model showed that the hindlimb feathers would create excessive drag during terrestrial running but would act as stabilizing airfoils during gliding descents.

The student wants to support the claim that *Microraptor*'s physical features are more consistent with the "trees-down" hypothesis than the "ground-up" hypothesis. Which choice most effectively uses information from the notes to accomplish this goal?

For decades, historians of literacy accepted the thesis that silent reading was an exceedingly rare anomaly in the ancient Mediterranean, citing Augustine’s surprise at seeing Bishop Ambrose read without making a sound as proof of its novelty. ______ subsequent examinations of classical texts have revealed that references to reading without speaking appear in works dating back to fifth-century BCE Athens, showing that the practice was familiar to literate Greeks and Romans long before Augustine's time.

The following passage discusses the origins of ancient writing systems. Complete the passage by typing the transition word or phrase that best establishes the logical relationship between the sentences in the blank.

Archaeologists studying the ancient city of Caral in Peru found evidence of advanced agricultural techniques, including complex irrigation canals that channeled water from nearby rivers to cultivate squash and beans. ______ the researchers discovered that the city's inhabitants traded these crops with coastal communities for fish and shellfish.

Which choice completes the passage with the most logical transition?

While preparing a presentation on colonial Jamaican history, a student takes the following notes:
* Maroons were communities of formerly enslaved Africans who fled plantations to establish independent settlements in the mountainous interior of Jamaica.
* Following decades of conflict, the British colonial government signed a peace treaty in 1739 with Cudjoe, leader of the Leeward Maroons.
* The treaty officially recognized Maroon autonomy, granting them land ownership and political self-governance.
* The agreement also required the Maroons to capture and return future runaway slaves to the British authorities.
* Additionally, the treaty obligated the Maroons to assist the British military in putting down future slave uprisings.

The student wants to support the claim that the 1739 treaty compromised the Maroons' alignment with other enslaved people in Jamaica despite securing their own independence. Which choice most effectively uses information from the given notes to accomplish this goal?

While conventional histories of the Silk Road emphasize the transit of luxury goods such as silk and lapis lazuli, some historians argue that the network's most profound impact was the transmission of mundane agricultural practices. ______ archaeological evidence from the Dunhuang oases indicates that regional farmers integrated West Asian irrigation designs and crop rotation systems, which permanently altered the local ecological and economic landscape.

While preparing a presentation on plant biology, a student took the following notes:
* Allelopathy is a biological phenomenon in which an organism produces biochemicals that influence the growth, survival, and reproduction of other organisms.
* These biochemicals are known as allelochemicals.
* Allelochemicals can have either positive (beneficial) or negative (detrimental) effects on target organisms.
* The term was first coined in 1937 by Austrian scientist Hans Molisch.
* Black walnut trees and rice crops are well-known examples of plants that use allelopathy to influence surrounding vegetation.

The student wants to provide a definition of allelopathy to an audience unfamiliar with the concept. Which choice most effectively uses relevant information from the notes to accomplish this goal?
