While preparing a presentation on pre-Columbian engineering, a student takes the following notes:

* The Chimú Empire (1000–1470 CE) constructed the Chicama-Moche canal to direct water through the arid Peruvian desert.
* To prevent water from eroding the canal's earthen banks, Chimú engineers designed it with a precise, gentle slope averaging only 1 to 2 meters of drop per kilometer.
* Tectonic uplift later altered the region's topography, disrupting the canal's slope alignment.
* Due to these geological changes, water could no longer flow through the canal, and the project was abandoned before completion.

The student wants to support the claim that the canal's abandonment was caused by geological activity rather than poor engineering. Which choice most effectively uses information from the given notes to accomplish this goal?

While preparing a presentation on marine sciences, a student took the following notes:

* Sclerochronology is a scientific discipline that studies the physical and chemical variations in the accretionary hard tissues of organisms.
* These tissues include mollusk shells and coral skeletons.
* The field is considered the marine counterpart to dendrochronology (tree-ring dating).
* Researchers analyze periodic growth increments in these hard tissues to reconstruct past marine environments.
* The term was coined in 1974 by geologist Richard A. Dodge.

The student wants to provide a definition of sclerochronology. Which choice most effectively uses information from the given notes to accomplish this goal?

Planetary geologists studying the surface of Mars have identified features that suggest ancient liquid water once flowed there in large quantities. However, determining the precise duration and stability of these ancient water bodies remains a challenge. __________, the discovery of clay minerals and hydrated silica in Jezero Crater indicates that liquid water must have persisted for thousands, if not millions, of years, as these minerals require sustained aqueous alteration to form.

While preparing a presentation on Rongorongo, a script from Easter Island, a student takes the following notes:
* Rongorongo is a system of glyphs discovered on Easter Island in the 19th century.
* In 1958, linguist Thomas Barthel published a catalog of the glyphs, identifying 120 basic signs.
* Barthel's work established a standardized numbering system for the glyphs, facilitating modern analysis.
* Some researchers claim that Rongorongo developed independently without external influence.
* Despite decades of study, scholars have not yet reached a consensus on the meaning or translation of the glyphs.

The student wants to support the claim that Rongorongo remains undeciphered despite historical efforts to systematically organize the script. Which choice most effectively uses information from the given notes to accomplish this goal?

Lichenometry is a dating technique used by geomorphologists to estimate the age of exposed rock surfaces based on the growth rates of specific lichen species. By measuring the maximum diameter of individual lichens on a glacial moraine, researchers can determine when the glacier ______ method is particularly useful for deposits that are less than a few thousand years old.

While preparing a presentation on early photography, a student took the following notes:

* The daguerreotype process, introduced in 1839, created a highly detailed image directly on a polished sheet of copper.
* Because each daguerreotype was unique, it could not be easily replicated or used to print multiple copies.
* The calotype process, patented in 1841, produced a paper negative from which multiple paper prints could be made.
* Although calotypes allowed for the mass production of prints, the resulting images were softer and lacked the fine detail of daguerreotypes.

The student wants to contrast the replication capability of the daguerreotype process with that of the calotype process. Which choice most effectively uses information from the given notes to accomplish this goal?

In 1977, marine scientists discovered hydrothermal vents on the ocean floor, revealing complex ecosystems that thrive in complete darkness. This pioneering exploration permanently ________ our understanding of biology and prompted researchers to rethink the conditions under which life could survive in the universe.

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

The green sea slug *Elysia chlorotica* is known for its ability to perform photosynthesis, a process typically reserved for plants. The slug achieves this by consuming the algae *Vaucheria litorea* and retaining its chloroplasts—the organelles responsible for photosynthesis—within its own digestive cells. This biological phenomenon, known as kleptoplasty, allows *E. chlorotica* to survive for up to nine months solely on light and carbon dioxide. While the slug extracts these chloroplasts, it does not inherit the algal genes required to maintain them. Instead, the chloroplasts eventually degrade, requiring the slug to feed on algae periodically throughout its life cycle to replenish them.

According to the text, which statement is true about the chloroplasts inside *Elysia chlorotica*?

Which inequality is equivalent to $-3(3x - 5) - 4 < -2x + 18$?

Complete the text with the most logical and precise word.

An environmentalist studies the sound level of a waterfall. The sound level, $S$, in decibels ($\text{dB}$), at a distance of $d$ meters from the base of the waterfall is modeled by the equation $S = 92 - 0.15d$, where $0 \leq d \leq 200$. What is the best interpretation of the $S$-intercept of the graph of this equation in the $dS$-plane?

A writer took the following notes while researching deep-sea exploration vessels:
* The submersible *Deepsea Challenger* was designed by filmmaker James Cameron.
* In 2012, the vessel reached the bottom of the Mariana Trench.
* The hull of the vessel was constructed from a specialized syntactic foam.
* It reached a maximum depth of 10,908 meters during its historic dive.
* Marine biologist Dr. Sandra Myres analyzed the sediment samples collected during the mission.

The writer wants to write a sentence that emphasizes the material composition of the *Deepsea Challenger*'s hull. Complete the sentence by filling in the blank with the correct detail from the notes.

A recent ecological survey of the unique wetlands in southern Florida reveals that the primary threat to local biodiversity is not urban sprawl but invasive plant species. A single population of these fast-growing weeds, despite efforts by conservationists to manage their spread, ________ the delicate balance of the native ecosystem by outcompeting local flora for sunlight and soil nutrients.

Text 1
More than four hundred carved stone spheres dating from the Neolithic period have been found across Scotland. Archaeologist Alistair Munro posits that these spheres, decorated with intricate geometric knobs, served primarily as status symbols or prestige items displayed by tribal leaders to signal wealth and social authority. Munro points to the significant labor required to carve such hard stones, as well as the polished finish on many specimens, to argue that they were prized non-utilitarian possessions rather than functional everyday items.

Text 2
While Munro views Scotland's Neolithic carved stone spheres as purely ceremonial displays of prestige, researcher Clara Vance offers a different interpretation. Vance highlights that the spheres exhibit a remarkably consistent average diameter of roughly 70 millimeters, regardless of the complexity of their carvings or the type of stone used. According to Vance, this high degree of dimensional uniformity suggests that the spheres functioned as standardized units of measurement or trade weights. She argues that their value lay not in representing abstract social status, but in facilitating economic transactions and building structural systems.

Based on the texts, how would Vance (Text 2) most likely characterize Munro's claim (Text 1) regarding the primary function of the carved stone spheres?

For decades, astrophysicists have struggled to explain the origin of elements heavier than iron, which require extreme conditions to form. Recently, the detection of gravitational waves from binary neutron star mergers, along with the subsequent observation of electromagnetic counterparts across multiple wavelengths, _______ invaluable data regarding this nucleosynthesis process.

While preparing a talk on biological classification, a student took the following notes:

* Cladistics is an approach to biological classification.
* In cladistics, organisms are categorized based on their shared evolutionary ancestry.
* The approach groups organisms into clades, which consist of a common ancestor and all its descendants.
* It was developed in the 1950s by German entomologist Willi Hennig, who referred to it as phylogenetic systematics.
* Cladistics differs from phenetics, an approach that groups organisms based on overall physical similarity.

The student wants to provide a definition of cladistics. Which choice most effectively uses information from the given notes to accomplish this goal?

In volcanology, the viscosity of magma is a primary factor determining the explosiveness of an eruption. Low-viscosity basaltic magma allows trapped gases to escape relatively easily, resulting in gentle, effusive lava flows. High-viscosity rhyolitic magma, conversely, prevents these gases from escaping freely ______ pressure builds up within the volcanic chamber until it releases in a catastrophic explosion.
