In 1783, Joseph-Michel and Jacques-Étienne Montgolfier launched the first manned hot air balloon in Paris. The balloon, constructed of paper and silk, rose over three thousand feet into the air and carried its passengers safely across the city. Today, hot air ballooning is a popular recreational activity and competitive sport worldwide. The success of this flight marked the beginning of human aviation, inspiring subsequent inventors to develop hydrogen balloons and gliders.

The following sentences are from a draft of an essay about chemist Alice Ball. To ensure that the paragraph logically builds its claim that Ball's work solved a major clinical hurdle in treating Hansen's disease, in what order should the sentences be placed?

Consider the following passage:

Umbrellas have a long history, dating back to ancient Egypt and Mesopotamia, where they were used primarily to shade royalty from the sun. In these early societies, umbrellas were symbols of power and status, made from palm leaves, feathers, or stretched papyrus. However, it was not until much later in ancient China that umbrellas were first waterproofed with wax and lacquer to provide protection against the rain.

[1] _________________________________________. For centuries, European men viewed them as a feminine accessory, associated almost exclusively with women of high social standing. It was not until the mid-eighteenth century, when an English traveler named Jonas Hanway began carrying an umbrella in public, that the device gained acceptance among men. Despite initial ridicule from carriage drivers who feared losing business, Hanway’s persistence eventually paid off, transforming the umbrella into a common and practical accessory for everyone.

Which of the following choices best introduces the main topic of the second paragraph?

In the deep, lightless zones of the ocean, the anglerfish uses a glowing lure to attract prey. This bioluminescent organ, called an esca, is filled with symbiotic <u>bacteria. Which produce</u> light through a complex chemical reaction. This glowing trap allows the predator to survive in an environment where food is extremely scarce.

Which of the following choices represents the correct punctuation at the underlined boundary?

Originating in Japan, *yakisugi* is a traditional method of wood preservation that involves charring the surface of cedar boards to make them resistant to fire, rot, and insects. The process begins by binding three boards into a triangular chimney, lighting the interior, and allowing the flames to rapidly carbonize the wood. This superficial burning creates a thick layer of carbonized cellulose, which acts as a natural barrier. Ultimately, the charred layer protects the underlying timber from environmental degradation, ensuring its longevity for decades.

The writer wants to revise the underlined portion of the sentence below to provide the most specific, concrete visual details that illustrate the physical appearance of the carbonized surface:

"This superficial burning creates a thick layer of carbonized cellulose, which acts as a natural barrier."

Which choice best accomplishes this goal?

Mary Anning was a pioneering English paleontologist who made several groundbreaking fossil discoveries in the cliffs of Lyme Regis. However, her path to success was not easy.

[1] She had many hobbies that kept her busy throughout her adult years. As a woman in nineteenth-century Britain, she was not allowed to join the Geological Society of London, and she was often excluded from the scientific community. Furthermore, male scientists frequently published academic papers about the fossils she found without giving her any credit.

Which choice most effectively replaces the underlined portion to introduce the paragraph by establishing its main focus?

In 1609, Galileo Galilei constructed an instrument that would revolutionize astronomy. The telescope that Galileo built, which had a magnification of three times, helped him discover the four largest moons of Jupiter. These observations challenged the geocentric model of the universe.

Which choice best punctuates the underlined portion of the sentence?

During the annual safety inspection, the two refineries' supervisors reviewed the safety procedures to ensure they're alignment with federal standards.

Which choice is the correct spelling and punctuation for the underlined portion of the sentence?

To reach the remote research station, the climatologists had to navigate the steep, narrow, mountain pass and they had to carry all of their scientific equipment on foot.

Which of the following choices for the underlined portion is correct?

Consider the following paragraph from an essay about Mayan architecture:

[1] The ancient Mayan pyramid El Castillo at Chichen Itza is celebrated not only for its imposing structure but also for its sophisticated acoustic design. [2] When visitors clap their hands at the base of the pyramid's staircase, the steps bounce the sound waves back as an echo. [3] This echo closely mimics the distinctive, high-pitched chirp of the resplendent quetzal, a sacred bird in Mayan mythology. [4] Researchers believe that Mayan architects intentionally engineered the staircase's dimensions—specifically the height and depth of each step—to produce this precise auditory illusion.

The writer wants to add a sentence after Sentence 3 that provides the most specific, concrete visual detail supporting the claim that the quetzal was highly revered in Mayan society. Which of the following sentences best accomplishes this goal?

In the sentence below, which punctuation mark should be placed in the blank to connect the two independent clauses grammatically?

In 1912, German meteorologist Alfred Wegener proposed the theory of continental drift, suggesting that Earth’s continents were once joined in a single supercontinent. Most of his contemporaries dismissed the idea because Wegener could not identify a physical mechanism that could move entire landmasses. He continued to gather supporting evidence until his death. Never seeing his revolutionary theory accepted by the scientific community.

Which of the following is the correct punctuation and phrasing for the underlined portion of the passage?

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?

[1] In 1938, Ruth Wakefield, owner of the Toll House Inn in Massachusetts, made culinary history when she decided to chop up a bar of semi-sweet chocolate and add it to her cookie dough. [2] She had expected the chocolate chunks to melt and swirl into the dough, but they instead retained their shape, creating the first chocolate chip cookie. [3] Over the years, many bakers have experimented with other cookie recipes, such as oatmeal raisin and peanut butter. [4] The recipe became an instant sensation among her guests, prompting Nestlé to print the Toll House recipe on their chocolate wrappers in exchange for providing Wakefield with a lifetime supply of chocolate.

Saving Sounds of the Past

[1]
For decades, archivists and historians struggled with a delicate problem: how to play the oldest recorded sounds in human history without destroying them. Early sound recordings from the late nineteenth century were captured on fragile materials like wax cylinders, tinfoil, and shellac discs. Every time a stylus was placed in the grooves of these media to play back the audio, the friction wore away a tiny bit of the soft material, slowly erasing the history it contained.

[2]
In the early 2000s, a breakthrough emerged from an unlikely place: particle physics. Physicist Carl Haber realized that the high-resolution optical cameras used to track subatomic particle collisions could be applied to audio preservation. By using these cameras to take thousands of micro-photographs of a record's surface, scientists could construct a detailed three-dimensional digital model of the groove.

[3]
Once the digital model is created, specialized software acts as a virtual stylus, calculating how a physical needle would move through the reconstructed grooves. This process, known as optical sound recovery, allows researchers to play back the audio without ever physically touching the delicate media. As a result, recordings that were previously considered unplayable due to damage or decay can now be heard clearly for the first time in over a century.

[4]
Through this technology, historians have recovered invaluable cultural artifacts. These include an 1885 recording of Alexander Graham Bell's voice and early traditional songs of Native American tribes. By bridging the gap between physics and history, optical recovery has ensured that these fragile auditory snapshots are preserved for future generations to study and appreciate.

Suppose the writer's goal had been to write an essay that details the historical evolution of audio playback devices from the late nineteenth century to the mid-twentieth century. Would this essay fulfill that goal?

To reconstruct the prehistoric environment, the researchers analyzed the fossilized microscopic, plant spores, and compared the results with modern soil samples.
