However, his discovery of Machu Picchu captured the world's imagination and brought global attention to Incan history.

Which choice, if added at Point [1], most effectively emphasizes the physical difficulty of Bingham's journey to the ruins?

Passage Excerpt:

Unlike European navigators who relied on magnetic compasses and sextants to chart their courses across the open ocean, ancient Polynesian wayfinders navigated vast distances of the Pacific by reading the natural world. They observed the paths of stars, the flight patterns of birds, and the subtle behavior of ocean currents. To teach apprentice navigators how to interpret these complex ocean wave patterns, experienced wayfinders constructed stick charts. [X] These devices did not represent physical distances in the way a modern map does. Instead, they served as abstract, mnemonic training aids.

Given that all the choices are true, which one provides the most specific and detailed description of the physical composition of the stick charts and how they functioned as wave diagrams?

Passage Excerpt:

In the winter of 1903, while visiting New York City, Mary Anderson noticed that a streetcar driver had to keep the front window open to clear falling sleet from the glass. Upon returning to her home in Alabama, she designed a hand-operated device to solve this problem. [1] She was granted a patent for her window-cleaning device in November 1903.

Given that all the choices are true, which choice, if added at Point [1], best supports the idea that Anderson's design was both simple and easy to operate?

Passage Excerpt:
In 1943, marine engineer Richard James was working in a shipyard when he accidentally knocked a tension spring off a shelf. To his amazement, the spring did not merely fall; it "walked" down a stack of books, onto a table, and then coiled itself neatly on the floor. James immediately realized the toy potential of this simple steel coil. [blank]

The writer wants to add a sentence at point [1] that emphasizes Silver's disappointment with the weak adhesive. Which choice best accomplishes this goal?

Passage Excerpt:

In the late nineteenth century, audio was captured on fragile, spinning wax cylinders. Over time, these cylinders have degraded, making them too delicate to be played by a physical stylus without destroying the recordings. To retrieve these sounds, scientists developed IRENE, a system that uses digital imaging. [Underlined: A camera captures high-resolution images of the grooves to create a 3D digital model, avoiding any physical contact.] This visual map is then translated by computer software back into audio, allowing archivists to preserve lost voices.

Question:

The writer wants to choose an option that most clearly explains the specific mechanism of the IRENE system while emphasizing how it protects the fragile cylinders from damage. Which choice best accomplishes this goal?

Passage Excerpt:

In 1930, Ruth Wakefield was preparing cookies at the Toll House Inn when she decided to chop up a bar of semi-sweet chocolate and add it to her dough. She expected the chocolate to melt completely, but instead, the small pieces retained their shape, [blank].

The writer wants to complete the sentence by choosing an option that emphasizes that the new cookies were immediately popular among the inn's visitors. Which choice best accomplishes this goal?

During a winter trip to New York City in 1902, Mary Anderson observed a trolley driver struggle to see through a sleet-covered windshield. The driver had to repeatedly open his window, leaning out into the freezing air to wipe the glass by hand. Upon returning to Alabama, Anderson sketched her solution: a wooden lever inside the vehicle connected to a rubber blade on the outside. [X]

Resorting to the passage above, the writer wants to add a sentence at the indicated point [X] that emphasizes the immediate skepticism Anderson's invention faced despite its practical utility. Which choice best accomplishes this goal?

Though modern surveyors once dismissed the Great Dismal Swamp as a stagnant wasteland, early nineteenth-century communities viewed the dense morass as a vital, albeit challenging, sanctuary. Fleeing from nearby plantations, many enslaved people established permanent, self-sufficient settlements deep within the swamp's interior. [1]

The writer wants to add a sentence at Point [1] that contrasts the swamp's role as a refuge for self-determination with the hostile, dehumanizing conditions of the plantations they left behind. Which choice most effectively accomplishes this rhetorical goal?

During the 2018 restoration of the Prague Astronomical Clock, conservators replaced the replica of the nineteenth-century calendar dial with a new version. The original paintings by Josef Mánes celebrate Bohemian agricultural life. [2] The new replica, however, featured thick, harsh outlines and stylized features that critics argued belonged in a mid-century comic book rather than on a medieval monument.

The writer wants to add a sentence at Point [2] that establishes a clear stylistic contrast between Mánes's original paintings and the newly installed replica. Which choice best accomplishes this goal?

During a trolley ride in a freezing New York City winter, Mary Anderson observed the driver repeatedly opening the front window pane to brush away falling sleet, exposing passengers to the biting cold. Determined to find a solution, she sketched a device featuring a hand-operated lever inside the vehicle linked to a rubber blade on the outside. Although she secured a patent for her mechanical sweeper in 1903, manufacturing companies rejected her design, viewing it as a dangerous distraction for drivers.

The writer wants to add a sentence at the end of the paragraph that contrasts the initial commercial failure of Mary Anderson's invention with its eventual universal adoption. Which choice best accomplishes this goal?

For decades after the Tudor warship *Mary Rose* was raised from the Solent in 1982, conservators kept the wooden hull constantly saturated with a chilled freshwater mist to prevent it from drying out and collapsing. Eventually, they began actively replacing the water in the wood cells with polyethylene glycol (PEG), a water-soluble polymer.

Given that all the choices are true, which choice most clearly highlights the transition from temporary preservation methods to a permanent, structural stabilization technique while emphasizing the scientific complexity of the process?

In 1895, Harvard University opened the Fogg Art Museum, but its lecture hall was a disaster; speakers' voices bounced off the semicircular plaster walls, creating a chaotic echo that rendered lectures completely unintelligible. The university turned to a young physics assistant professor, Wallace Sabine, to solve the problem. Sabine painstakingly tracked the sound decay in the room, using a pipe organ and a stopwatch to measure the time it took for sound to become inaudible. He discovered that the duration of the reverberation was directly proportional to the room's volume and inversely proportional to the sound-absorbing qualities of its surfaces. [X] Ultimately, this breakthrough allowed him to calculate the exact amount of felt padding needed to absorb the excess sound, founding the modern science of architectural acoustics.

Given that all the choices are true, which one transitions most effectively from the discovery of the mathematical relationship to the practical application of it, while emphasizing the arduous nature of Sabine's experimentation?

Passage excerpt:

When the Paris Métro opened in 1900, the transit company sought to make the new underground railway inviting rather than intimidating. They commissioned architect Hector Guimard, whose modular cast-iron entryways came to define the city's aesthetic. Guimard’s designs utilized organic forms—such as arches resembling orchid stalks and glass canopies shaped like butterfly wings—to ease the public's transition from the familiar streets into the dark, subterranean platforms. By blending these natural motifs with structural metal, he created spaces that felt open and organic.

The writer wants to replace the bolded sentence with one that highlights how the physical architecture of the entrances specifically countered the public's fear of descending into a dark, subterranean space. Which choice best accomplishes this goal?

Passage Excerpt:

For centuries, scientists have marveled at the durability of ancient Roman concrete, which has survived for two millennia in harsh marine environments. Recently, researchers discovered that the Romans used a hot-mixing method, leaving small, white mineral fragments known as 'lime clasts' throughout the material. Previously, these lime clasts were once dismissed as a sign of poor mixing.

Prompt:

Given that all the choices are true, which choice most effectively highlights the active, self-healing role that lime clasts play in maintaining the structural integrity of Roman concrete over time?

Passage Excerpt:

Before the invention of radar, the British military constructed acoustic mirrors along the Kent coast to detect the drone of approaching enemy aircraft. [Sentence] These monolithic structures functioned like giant ears, reflecting sound waves onto a central microphone. However, the rapidly increasing speed of modern aircraft in the late 1930s soon rendered this network obsolete.

Which choice most effectively emphasizes the immense scale and distinctive geometry of the acoustic mirrors, highlighting their visual impact on the coastline?
