Which of the following choices best eliminates the redundancy in the underlined portion?

Although nineteenth-century philologists could find no written records of the ancient tongue, they successfully reconstructed Proto-Indo-European, which was a prehistoric ancestral language from which later modern languages descended from in the past.

Which choice is the most effective and concise alternative to the underlined portion of the sentence?

By analyzing the calcified dental plaque of ancestral populations, biochemists can extract remarkably preserved proteins that reveal prehistoric dietary habits. This biochemical approach offers direct evidence of ancient nutrition, bypassing the need for speculative inferences. Scientists can now reconstruct prehistoric diets down to the nitty-gritty.

Which choice best maintains the established tone of the passage?

Early cartographers faced immense challenges when mapping uncharted territories. Without modern satellite technology, they had to rely on celestial navigation and physical measurements. These early mapmakers had to be extremely picky about their calculations, as even a minor error could lead sailors miles off course.

Which choice is most precise and consistent with the tone of the passage?

Read the passage below about Roman engineering. Fill in the blank with the word that most precisely and clearly completes the sentence while maintaining the passage's formal tone.

The passage below is adapted from an article about document conservation.

When archivist Amanda Stone first examined the nineteenth-century ship logs, she noticed that the ink had begun to fade under the relentless humidity. To prevent further decay, she recommended that the museum store the documents in a climate-controlled vault. By maintaining a constant temperature and minimal moisture, the staff could arrest the degradation of the delicate fibers. This preservation effort ensured that future generations of historians could study these primary sources.

Which choice most precisely and clearly fits the context of the sentence?

In 1913, journalist Arthur Wynne created a new game for the *New York World* newspaper. Initially called a 'Word-Cross,' this puzzle was shaped like a diamond with a hollow center. Wynne's creation proved to be incredibly popular, and it established a precedent that would soon go on to become a staple of newspapers across the country.

Which of the following is the best revision of the underlined portion?

Biologists studying New Caledonian crows have observed that these birds can fashion hooks from twigs. By manufacturing and creating these tools, the crows can easily extract insects from deep within tree bark.

Which of the following options represents the most effective way to write the underlined portion of the sentence?

Read the passage below about elephant migration. Which precise and clear word should be placed in the blank to describe the matriarch's comprehensive, far-reaching knowledge of the terrain?

Read the following passage segment:

Although the new software was designed to streamline inventory management, several employees remained indifferent of the technology, preferring their traditional paper logs.

Which of the following options represents the correct idiomatic word choice to replace the underlined portion?

Early motion pictures were recorded on cellulose nitrate film, a material that was both highly flammable and chemically unstable. Over time, these historical reels undergo a process of decay, releasing acidic gases that degrade the emulsion until the image is completely lost. To halt this deterioration, archivist crews laboring in specialized vaults have to check out the films on a regular basis to monitor their condition. If a reel shows signs of decay, it is immediately copied onto a modern, stable polyester base.

Which choice most effectively maintains the established tone of the passage and is most concise?

Venus flytraps are carnivorous plants that capture their prey using specialized leaves. When an insect touches the sensitive trigger hairs on the inner surface of the trap, the leaves snap shut in a fraction of a second. [1] The rapid closure of the trap, which happens in a very fast and quick manner, prevents the insect from escaping. The plant then secretes digestive enzymes to break down its meal.

Which choice most effectively and concisely completes the sentence?

Read the following passage segment:

Although the new commercial drone is capable to fly in turbulent weather, the operators decided to postpone the survey flight until the storm subsided.

Which of the following options represents the correct idiomatic phrasing for the underlined portion of the sentence?

In 1856, eighteen-year-old chemist William Henry Perkin was attempting to synthesize quinine, a treatment for malaria, in his home laboratory. Instead of obtaining the expected clear liquid, he produced a dark, sticky sludge. Rather than discarding the failed experiment, Perkin washed the flask with alcohol and noticed a beautiful purple residue. This accidental discovery resulted in mauveine, the world’s first synthetic organic dye. Before Perkin’s breakthrough, purple textiles were exceedingly rare, as the color could only be extracted from expensive natural sources like marine snails. Consequently, Perkin's new dye became super popular and hit it big in the nineteenth-century fashion industry, transforming the worlds of chemistry and apparel design.

Given that all the choices are grammatically correct, which one best maintains the established tone and style of the passage?

In 1911, explorer Hiram Bingham climbed into the Peruvian Andes and encountered Machu Picchu, an ancient citadel from the past that was built by the Inca.

Which word best completes the blank?

In 1967, astrophysicist Jocelyn Bell Burnell was analyzing radio telescope data when she noticed a series of rapid radio pulses. These pulses, which occurred with a highly precise regularity and kept repeating at constant intervals, initially baffled astronomers, who jokingly named the source 'LGM-1' for 'Little Green Men.'

Which choice most effectively and concisely replaces the underlined portion of the sentence?

Mycorrhizal fungi establish symbiotic networks with plant roots, facilitating the exchange of nutrients and water. These subterranean pathways connect individual plants, allowing them to share resources and transmit chemical warning signals. Scientists have observed that when a host plant is attacked by herbivores, it sends warnings through this network, which helps neighboring plants prepare their defenses. $\underline{\text{So basically, this awesome web}}$ functions as an ecological communications infrastructure.

Which choice best maintains the established tone of the passage?

The following passage is adapted from an essay about medieval architecture.

Gothic cathedrals are renowned for their soaring heights and intricate designs, which were made possible by key structural innovations. The pointed arch, for instance, distributed weight more efficiently than the rounded Romanesque arch, allowing walls to be built taller and thinner. To prevent these high walls from collapsing outward, medieval masons developed flying buttresses, which towed the lateral thrust of the roof to external supports. This arrangement not only stabilized the massive stone structures but also freed up wall space for expansive stained-glass windows.
