Evaluating Whole-Essay Goals and Purpose

The following passage is an essay about Marie Tharp and ocean mapping.

[1]
For decades, the consensus among geologists was that the ocean floor was a flat, featureless plain. In the early 1950s, Marie Tharp, a geologist and cartographer at Columbia University, set out to challenge this assumption. Working with raw topographic data collected by her colleague Bruce Heezen, Tharp spent years drafting detailed profiles of the Atlantic Ocean floor. Because women were barred from working on research vessels at the time, Tharp relied entirely on Heezen's sonar data, painstakingly hand-drawing the underwater landscapes.

[2]
As Tharp plotted the data points, she noticed a distinct V-shaped valley running down the center of the Mid-Atlantic Ridge. She hypothesized that this feature was a rift valley, which would indicate that the ocean floor was spreading apart. This concept of continental drift was highly controversial and widely dismissed by the scientific community at the time. When Tharp first showed her findings to Heezen, he dismissed it as "girl talk." Undeterred, Tharp insisted on re-evaluating the data until Heezen was convinced, leading to their collaborative publication of the first physiographic map of the North Atlantic in 1957.

[3]
Tharp and Heezen's map revolutionized the field of earth science, providing visual evidence that supported the theory of plate tectonics. By showing that the ocean floor was dynamic and actively changing, their work transformed our understanding of how Earth's crust is formed and recycled. Today, Tharp is recognized not only for her monumental contributions to marine cartography but also as a pioneer who broke through the gender barriers of mid-century academia.

Suppose the writer's goal had been to write an essay that profiles the collaborative relationship between Marie Tharp and Bruce Heezen, emphasizing their shared academic backgrounds and mutual career development. Would this essay fulfill that goal?

In 1856, eighteen-year-old chemist William Henry Perkin was attempting to synthesize quinine, a treatment for malaria, in his home laboratory in London. Instead of obtaining a clear drug, Perkin ended up with a dark, sludge-like residue. When he attempted to clean the flask with alcohol, the mixture turned a brilliant purple. Recognizing the potential of the vibrant hue, Perkin realized he had accidentally created the first synthetic organic dye, which he eventually named mauveine.

Prior to Perkin’s discovery, dyes were derived exclusively from natural sources like plants, insects, and minerals. Purple, historically harvested from the glands of Mediterranean sea snails, was so rare and expensive that it was reserved almost entirely for royalty. Mauveine transformed this landscape. Because it could be mass-produced in a laboratory at a fraction of the cost, purple fabric suddenly became accessible to the general public. Perkin quickly patented his process, secured financial backing, and built a factory to manufacture the dye, sparking a fashion craze across Europe.

Perkin’s success did more than just revolutionize fashion; it laid the foundation for the modern chemical industry. The methods used to synthesize mauveine demonstrated that valuable organic compounds could be engineered systematically from coal tar, a waste product of coal gas production. This breakthrough prompted researchers to develop synthetic colors, artificial pharmaceuticals, and new plastics. By transforming chemistry from a descriptive science to a creative, industrial enterprise, Perkin’s accidental residue reshaped the modern world.

Suppose the writer’s goal had been to write an essay demonstrating how an accidental laboratory discovery influenced both nineteenth-century European fashion and the trajectory of industrial chemistry. The essay successfully achieves this goal.

The following passage is an essay about early sound recording technology.

[1]
In 1857, French inventor Édouard-Léon Scott de Martinville patented the phonautograph, a device designed to visually record sound waves onto paper blackened by the soot of a plasterer’s lamp. As a speaker sang or spoke into a horn, a membrane vibrated, causing a stylus to etch wavy lines onto the rotating paper cylinder. Unlike Thomas Edison’s phonograph, which would emerge two decades later, Scott’s invention was not designed to play sound back. Instead, Scott believed that humans could learn to "read" the visual squiggles of the phonautograms just as one reads text. Consequently, these earliest recordings of the human voice remained silent, locked in archival sheets for over a century.

[2]
The silence was finally broken in 2008 when an international team of scientists and historians collaborated to play back Scott's recordings. Using high-resolution digital scans of the paper phonautograms, researchers at the Lawrence Berkeley National Laboratory employed a virtual stylus to trace the etched lines. By converting these physical undulations into digital audio, they successfully reconstructed the sound of a human voice singing a snippet of the French folk song "Au Clair de la Lune." The recording, dated April 9, 1860, is widely recognized as the oldest known recording of a human voice, predating Edison’s first acoustic playback by seventeen years.

[3]
Beyond their historical novelty, these restored phonautograms have fundamentally altered our understanding of early acoustic technology. They demonstrate that the desire to capture sound existed long before the technology to play it back was developed. Furthermore, the recovery process highlighted the power of modern optical imaging to preserve fragile historical media. Today, archivists continue to apply these digital techniques to retrieve lost sounds from wax cylinders and shellac discs, ensuring that the ephemeral voices of the past can be heard by future generations.

Suppose the writer’s goal had been to write an essay demonstrating that Thomas Edison's phonograph was directly inspired by Édouard-Léon Scott de Martinville's phonautograph. Is the statement that the essay successfully achieves this goal true or false?

The Antikythera Puzzle

[1]
In 1901, divers salvaging an ancient Roman shipwreck near the Greek island of Antikythera recovered a corroded, lumpish bronze artifact. For decades, the calcified object remained largely ignored in the storerooms of the National Archaeological Museum in Athens, appearing to be little more than a formless mass of metal and stone. It was not until the mid-twentieth century, when researchers began using X-ray imaging, that the artifact's true nature began to emerge. Beneath its encrusted exterior lay a complex system of dozens of interlocking bronze gears, precisely cut and arranged with mathematical precision.

[2]
This device, now known as the Antikythera Mechanism, is widely considered the world's oldest known analog computer. Dating back to the second century BCE, it was designed to calculate and display astronomical positions, the phases of the moon, and the timing of eclipses with astonishing accuracy. It even tracked the four-year cycle of the ancient Olympic Games. The sophistication of its gear trains, particularly its use of a differential gear to calculate the synodic month, represents a level of mechanical engineering that would not reappear in European clockmaking for another fifteen hundred years.

[3]
The discovery fundamentally challenged long-held historical assumptions about the technological capabilities of ancient Greek civilization. Before the mechanism was fully analyzed, historians generally believed that complex geared technology arose only in the late Middle Ages. The Antikythera Mechanism proved that ancient mechanics had already mastered advanced gearing principles, showing that technological progress is not always a linear, continuous march forward, but can instead be lost to time and subsequently reinvented.

Suppose the writer's goal had been to write an essay that outlines the timeline of the Antikythera Mechanism's investigation and explains how its mechanical complexity challenged prevailing historical narratives regarding ancient engineering. The writer successfully achieved this goal.

[1]
For decades, the clay tablets unearthed at the ancient palace of Knossos on Crete remained an inscrutable enigma. Discovered by archaeologist Arthur Evans in 1900, the script—dubbed "Linear B"—defied translation. Evans believed that the tablets recorded a non-Greek Minoan language, and his towering authority in the field led most scholars to follow his lead, searching in vain for connections to ancient languages of the Near East.

[2]
Enter Michael Ventris, an English architect who had been obsessed with the mystery since hearing Evans speak about it during his schooldays. Unlike academic linguists who worked within rigid paradigms, Ventris approached the script as a cryptanalyst. He began by meticulously constructing grids that mapped the relationships between different signs, noting which symbols appeared together and how word endings changed depending on context.

[3]
In 1952, Ventris made a breakthrough. By analyzing place names on the tablets, he realized that the phonetic values of the symbols aligned perfectly with archaic Greek nouns and verbs. Working alongside classical scholar John Chadwick, Ventris proved that Linear B was not a foreign tongue at all, but rather the earliest written form of Greek, dating back some five centuries before Homer.

[4]
The decipherment revolutionized our understanding of the Bronze Age Aegean. It revealed that the Mycenaeans, not the Minoans, ruled Knossos in its final phase and showed that their society was highly bureaucratic, keeping detailed inventories of sheep, oil, and bronze. Ventris’s outsider status and grid-based methodology had unlocked a civilization's voice.

Suppose the writer’s goal had been to write an essay that demonstrates how Michael Ventris’s cryptanalytic methodology successfully challenged Arthur Evans’s theory about the linguistic origin of the Knossos tablets. Is the statement that the essay successfully achieves this goal True or False?

The QWERTY Legacy

[1]
Walk into any modern office or open a laptop, and you will find the same arrangement of letters on the keyboard: Q, W, E, R, T, and Y in the top-left row. This layout, known as QWERTY, is so ubiquitous that it seems like a natural law of technology. However, its origins lie in the mechanical limitations of the nineteenth century rather than any modern ergonomic design.

[2]
In the 1870s, Christopher Latham Sholes, a newspaper editor and printer from Milwaukee, developed the first commercially successful typewriter. His early prototypes had keys arranged alphabetically, but this setup caused a major problem. When typists typed rapidly, the typebars—the metal arms holding the letters—would swing up and collide, jamming the machine. To solve this, Sholes rearranged the keyboard layout.

[3]
A common myth is that Sholes designed QWERTY to deliberately slow down typists. In reality, he positioned frequently used letter pairs, such as 'TH' or 'HE,' on opposite sides of the keyboard. This separation ensured that the typebars would not strike in rapid succession and jam. The layout was not meant to hinder typing speed, but rather to allow for a continuous, jam-free typing rhythm.

[4]
Despite the rise of electronic keyboards and alternative layouts like the Dvorak Simplified Keyboard, which places the most common letters on the home row to reduce finger movement, QWERTY remains the global standard. Path dependency—the tendency of users to stick with an established technology because it is too costly or difficult to retrain—has cemented QWERTY’s position, proving that history often triumphs over efficiency.

Suppose the writer’s goal had been to write an essay that explains the mechanical necessity that led to the QWERTY layout and argues for its replacement by more modern, efficient keyboard layouts. Based on the passage, is the statement that the writer successfully achieved this goal true or false?

During the 1904 World's Fair in St. Louis, Missouri, concession stands were bustling with visitors from all over the world. Among these vendors was Arnold Fornachou, who sold ice cream. On a particularly hot day, Fornachou ran out of paper bowls to serve his popular treats.

Ernest Hamwi, a Syrian immigrant, was operating a waffle booth next to Fornachou's stand. Hamwi noticed his neighbor's predicament. Quickly rolling one of his thin, warm waffles into a cone shape, Hamwi handed it to Fornachou, who placed a scoop of ice cream on top. The customer was delighted, and a legendary combination was born.

This simple act of quick thinking changed the history of dessert. Soon, ice cream cones were being manufactured nationwide, turning a temporary solution into a beloved global tradition.

Suppose the writer's goal had been to write an essay that describes how a challenge faced by a vendor at the 1904 World's Fair led to a popular culinary invention. Would this essay successfully fulfill that goal?

The following passage is about Mary Anning, a nineteenth-century fossil collector.

[1]
Mary Anning was born in 1799 in Lyme Regis, a coastal town in Dorset, England. Her father, a cabinetmaker, frequently took Mary and her brother Joseph to the nearby cliffs to search for fossils to sell to tourists. This family trade, initially born of economic necessity, soon became Mary's lifelong passion. Despite her lack of formal education in science, Anning possessed an extraordinary eye for detail and an unmatched persistence, which would lead her to some of the most significant paleontological discoveries of the nineteenth century.

[2]
In 1811, when Mary was only twelve years old, she and Joseph discovered the skeleton of what was later named an Ichthyosaurus, a giant marine reptile that lived during the Jurassic period. A few years later, Mary discovered the first complete Plesiosaurus skeleton, a creature so bizarre that many scientists of the era initially believed it to be a fake. These findings, along with her discovery of the first pterosaur skeleton outside of Germany, challenged existing scientific theories about the history of the Earth and the extinction of species, providing crucial evidence for the emerging field of geology.

[3]
Despite her monumental contributions, Anning was largely excluded from the male-dominated scientific community. The Geological Society of London refused to admit her, and male scientists often published papers about her discoveries without giving her any credit. Nevertheless, her expertise was widely recognized by leading geologists of the day, who frequently visited Lyme Regis to consult with her. Today, Anning is celebrated not only for her groundbreaking discoveries but also as a pioneer who broke down barriers for women in science.

Suppose the writer's primary goal had been to write an essay focusing on the challenges Mary Anning faced as a female scientist in nineteenth-century England. Would this essay fulfill that goal?

In the late nineteenth century, the bicycle underwent a dramatic transformation. Prior to this era, the "ordinary bicycle"—often called the penny-farthing—dominated the roads. With its massive front wheel and tiny rear wheel, it was notoriously difficult to mount and highly dangerous to ride. A sudden stop could send the rider flying over the handlebars, a mishap colorfully known as "taking a header." Consequently, cycling remained the exclusive domain of athletic, adventurous young men.

This barrier fell with the introduction of the "safety bicycle" in the 1880s. Featuring two wheels of equal size, a steerable front wheel, and a chain-driven rear wheel, this new design was stable and accessible to the general public. Pneumatic rubber tires, invented shortly thereafter, replaced solid rubber ones, offering a far smoother ride over the unpaved streets of the time. Almost overnight, cycling transformed from a hazardous stunt into a popular form of recreation and daily transportation.

The social impact of the safety bicycle was profound, particularly for women. Standard Victorian attire, with its heavy layers, tight corsets, and floor-length skirts, made riding virtually impossible. To accommodate the bicycle, women began adopting "rational dress," which included bloomers—loose-fitting trousers gathered at the ankle—and shorter skirts. This shift in fashion symbolized a broader movement toward physical freedom and social independence.

Suffragist leaders quickly recognized the political power of this invention. Susan B. Anthony famously remarked in 1896 that the bicycle had "done more to emancipate women than anything else in the world." By granting women independent mobility, the bicycle helped dismantle the restrictive notion that women's lives should be confined solely to the domestic sphere.

Based on the passage above, is the following statement true or false?
"Suppose the writer’s goal was to write an essay that explains how the transition from the ordinary bicycle to the safety bicycle influenced women’s fashion and social independence in the late nineteenth century. The essay successfully achieves this goal."

Suppose the writer's goal had been to write an essay that highlights the construction timeline and key structural features of the Empire State Building. Based on the provided essay, is the statement that the essay successfully fulfills this goal true or false?

[1] The Empire State Building, completed in 1931, stands as a monument to early twentieth-century engineering. Rising 1,250 feet above the streets of Midtown Manhattan, it was constructed in just thirteen months during the Great Depression. The building’s framework consists of a massive steel grid designed to withstand high winds and support the limestone cladding that covers its exterior.

[2] At the core of this engineering marvel was the innovative use of hot-riveted steel columns. Workers, known as "sky boys," balanced on narrow beams hundreds of feet in the air to assemble the frame. They heated steel rivets in small furnaces until red-hot, tossed them across open gaps to catchers, and hammered them into place to secure the joints. This dangerous and fast-paced labor allowed the steel skeleton to rise at an astonishing rate of four and a half stories per week.

[3] While newer skyscrapers utilize concrete cores and composite materials, the Empire State Building remains a symbol of the steel-frame era. Today, it continues to serve as an active office building and a world-famous tourist attraction, demonstrating the enduring strength and utility of its original structural design.

An Accidental Invention

[1]
In 1945, self-taught engineer Percy Spencer was working at Raytheon, a company that manufactured magnetrons for radar systems. One day, while standing near an active radar transmitter, Spencer noticed something unusual in his pocket: a chocolate bar he was carrying had completely melted. Intrigued, he decided to investigate further by placing other food items, including popcorn kernels, near the machine. To his delight, they quickly popped.

[2]
Spencer realized that the microwave radiation from the magnetron could cook food much faster than traditional ovens, which relied on external heat. Raytheon patented the technology, and in 1947, the company introduced the first commercial microwave oven. This early model was massive, weighing nearly 750 pounds and standing almost six feet tall, making it impractical for home kitchens.

[3]
Over the next few decades, engineers worked to shrink the technology and reduce its cost. By the late 1960s, affordable countertop models became available, permanently transforming how people around the world prepare meals. Today, the microwave is a staple of modern convenience, all thanks to a melted chocolate bar.

Suppose the writer's goal had been to write an essay that describes the accidental discovery of the microwave oven and its evolution into a common household appliance. The essay successfully achieves this goal.

The following passage is about Mary Anderson's invention of the windshield wiper.

[1]
During a winter trip to New York City in 1903, Mary Anderson noticed that streetcar drivers had to open their front windows or step outside to wipe sleet and snow off the windshields. This practice not only chilled the passengers but also slowed down transit times. Anderson began sketching a solution: a manual lever inside the vehicle that controlled a rubber blade on the outside of the window.

[2]
Upon returning to her home in Alabama, Anderson hired a designer to create a working model of her invention. She successfully patented her "window cleaning device" later that year. Although early car manufacturers did not immediately see the value of her invention, by the 1920s, windshield wipers had become standard equipment on most automobiles.

[3]
Today, Anderson is recognized as a pioneer of automotive safety. Her simple, mechanical invention solved a major transportation hazard and paved the way for modern driving convenience.

Suppose the writer's goal had been to write an essay that describes how Mary Anderson came up with and developed the idea for the windshield wiper. Would this essay successfully fulfill that goal?

The following passage is about the ecological effects of reintroducing wolves to Yellowstone National Park.

Restoring the Balance

[1]
In 1995, conservationists reintroduced gray wolves to Yellowstone National Park, ending a seventy-year absence of the apex predator. During the wolves’ absence, the park's elk population had soared, leading to severe overgrazing of young willow, aspen, and cottonwood trees along valley bottoms. Lacking competition and predators, the elk had stripped the riverbanks bare, causing significant erosion and altering the local ecosystem.

[2]
The return of the wolves quickly initiated a phenomenon known as a trophic cascade. As wolves hunted the elk, the herbivores' behavior shifted; they began avoiding low-lying areas where they could be easily cornered. Consequently, the vegetation along the riverbanks began to recover. Willows and aspens grew taller, providing shade that cooled the water, which in turn benefited native trout species.

[3]
With the regrowth of trees, songbirds returned to the valleys, and beavers found the materials they needed to build dams. Beaver ponds created wetlands that supported insects, amphibians, and waterfowl. By modifying the behavior of a single herbivore, the wolves indirectly reshaped the physical geography and biological diversity of the entire park, proving that predators are essential to maintaining healthy ecosystems.

Suppose the writer’s goal had been to write an essay that explains how the reintroduction of a predator can restore biodiversity and physically alter an ecosystem's landscape. Would this essay accomplish that goal?

The following passage is about the origin of the chocolate chip cookie.

[1] In 1938, Ruth Wakefield, co-owner of the Toll House Inn in Massachusetts, made a culinary decision that changed baking history. While preparing a batch of chocolate cookies, she realized she was out of baker's chocolate. Improvising, she chopped up a bar of semi-sweet chocolate, expecting it to melt entirely into the dough during baking.

[2] To her surprise, the chocolate bits did not melt completely; instead, they softened into distinct, gooey pockets of chocolate within the cookie. The guests at the inn praised the new creation, which she named the Toll House Chocolate Crunch Cookie. Its popularity grew rapidly, prompting a partnership with Nestlé to print her recipe on their packaging.

[3] Today, the chocolate chip cookie remains one of the most popular desserts in the United States. Wakefield’s invention demonstrates how an unexpected change in a recipe can lead to a beloved culinary tradition.

Suppose the writer's goal had been to write an essay focusing on the historical origin and accidental creation of the chocolate chip cookie. Does this essay successfully fulfill that goal?

The Sticky Note Solution

[1]
In 1968, a chemist named Spencer Silver was working at the 3M company, trying to develop a super-strong adhesive for the aerospace industry. Instead, he accidentally created something quite different: a weak adhesive that stuck lightly to surfaces, could be peeled off easily, and left no residue behind. For several years, Silver promoted his unusual adhesive within the company, but no one could think of a practical use for it.

[2]
The breakthrough came in 1974, when another 3M scientist, Art Fry, attended a seminar where Silver was explaining his adhesive. Fry sang in his church choir and was frustrated that the scraps of paper he used as bookmarks kept falling out of his hymnal. He remembered Silver’s adhesive and realized it would be perfect for making sticky bookmarks that could hold their place without damaging the pages of the hymnal.

[3]
Fry and Silver worked together to develop the product, and 3M eventually launched it in 1980 under the name "Post-it Notes." The yellow square notes quickly became an indispensable office staple worldwide, proving that a failed scientific experiment could lead to a highly successful commercial product.

Suppose the writer's goal had been to write an essay detailing the step-by-step invention and commercial release of the Post-it Note. Would this essay accomplish that goal?

The following passage is about the history of musical pitch standardization.

For centuries, musicians tuned their instruments to varying reference pitches. A performer traveling from Paris to London in the eighteenth century would find that what was considered "middle A" in one city might sound nearly a semitone higher or lower in another. This lack of standardization posed significant challenges, particularly as orchestras grew larger and instrument manufacturing became more globalized.

In $1939$, an international conference in London officially recommended that the note $A$ above middle $C$ be tuned to $440 \text{ Hz}$. This frequency, known as $A440$, was chosen as a compromise. It balanced the desires of singers, who preferred lower pitches to avoid vocal strain, with those of string players and instrument makers, who favored higher pitches for a brighter, more brilliant sound.

Today, $A440$ remains the standard reference pitch for tuning in most Western classical and popular music. Although some modern orchestras tune slightly higher—often to $442 \text{ Hz}$ or $443 \text{ Hz}$ to achieve a more piercing tone—the establishment of $A440$ was a milestone that facilitated global musical collaboration and standardized instrument production.

Suppose the writer's goal had been to write an essay that explains why a standardized musical pitch was established and how it was decided. Would this essay successfully fulfill that goal?

Zhang Heng's Seismoscope

[1]
In 132 CE, during the Han Dynasty, the Chinese polymath Zhang Heng introduced an extraordinary invention to the imperial court: the Houfeng Didong Yi, widely regarded as the world's first seismoscope. To a court routinely threatened by devastating earthquakes, the device promised crucial advanced warning. It was a large, ornate bronze vessel, resembling a wine jar, with a diameter of nearly six feet. On its outer surface, eight dragons faced downward, each holding a bronze ball in its mouth. Directly beneath them sat eight bronze toads, their mouths open and facing upward to receive the balls.

[2]
The internal mechanism of the vessel was a closely guarded secret, but modern reconstructions suggest it relied on a central pendulum. When a tremor occurred, even one imperceptible to humans, the ground's movement would sway the pendulum. This motion triggered a series of internal levers, releasing the ball from the mouth of the dragon facing the direction of the earthquake's origin. The ball would drop into the open mouth of the toad below with a loud clang, alerting the court to both the occurrence and the approximate direction of the seismic activity.

[3]
Initially, imperial officials were skeptical of the device's utility, especially when a ball dropped one day without any visible tremor felt in the capital. However, days later, a messenger arrived to report that an earthquake had indeed occurred hundreds of miles away in the direction indicated by the empty dragon's mouth. Despite its success, the exact design of the seismoscope was lost to history when the Han Dynasty fell, leaving future generations to marvel at its sophistication through historical texts alone.

Suppose the writer's goal had been to write an essay that details the broad range of scientific, mathematical, and literary contributions made by Zhang Heng throughout his lifetime. Is the statement that this essay successfully achieves this goal true or false?

A Popping Success

[1]
In 1957, engineers Alfred Fielding and Marc Chavannes set out to create a textured, three-dimensional wallpaper. They attempted to laminate two plastic shower curtains together, sealing them with heat. However, the process trapped tiny pockets of air between the sheets. Although the wallpaper idea was a commercial failure, the inventors refused to abandon their creation.

[2]
They first attempted to market the bubbly material as greenhouse insulation. While it worked reasonably well, sales remained low. The true breakthrough came a few years later when Marc Chavannes realized the material’s potential for protecting fragile items during transport.

[3]
In 1960, they founded Sealed Air Corporation and branded their product as Bubble Wrap. Their first major client, IBM, used it to ship the delicate IBM 1401 computer. Today, Bubble Wrap is a staple of the shipping industry, protecting millions of packages worldwide.

Suppose the writer's goal had been to write an essay that highlights the history of Bubble Wrap, focusing on how a failed design for wallpaper became a successful packaging material. This goal was successfully met by the essay.

Josephine’s Invention

[1]
In the late nineteenth century, Josephine Cochrane, a wealthy socialite from Illinois, grew frustrated with a common household problem. Although she did not wash dishes herself, her servants frequently chipped her fine heirloom china while cleaning it. Determined to find a better solution, Cochrane resolved to build a machine that could wash dishes faster and more safely than human hands.

[2]
Working in a shed behind her home, Cochrane designed a machine that used high water pressure rather than scrubbers to clean. She measured the dishes first, constructing wire compartments tailored to fit plates, cups, and saucers. These compartments were placed inside a copper boiler, which rotated while hot, soapy water was sprayed from the bottom. Cochrane patented her invention in 1886, naming it the Cochrane Dishwasher.

[3]
Initially, Cochrane’s invention was not designed for the average home, which lacked the plumbing and hot water heaters necessary to run the machine. Instead, she found success selling her large-scale washers to hotels, restaurants, and hospitals, where efficiency and sanitation were paramount. Cochrane’s design laid the foundation for the modern household appliance that is now common in kitchens worldwide.

Suppose the writer’s goal had been to write an essay that describes the technical and mechanical difficulties Cochrane encountered while building her first prototype. Would this essay successfully fulfill that goal?

The following passage is about the history of Manhattan's street layout.

Manhattan's Grid

[1]
In the early nineteenth century, New York City was growing rapidly, yet its street layout was a chaotic jumble of narrow, winding pathways. To bring order to this expanding metropolis, the state legislature appointed a commission in 1807 to design a new street system. The resulting proposal, known as the Commissioners' Plan of 1811, introduced the iconic rectangular grid of streets and avenues that defines Manhattan today.

[2]
The planners prioritized practicality over aesthetic elegance. They rejected circular designs or diagonal boulevards, which were popular in European capitals, in favor of right-angled intersections. This layout maximized the utility of building lots and simplified the buying and selling of real estate. While some critics argued that the grid was monotonous, its efficiency facilitated the city's commercial explosion.

[3]
Today, the grid remains the structural backbone of Manhattan. It has proven remarkably adaptable, accommodating millions of residents, skyscrapers, and transit systems that the original planners could scarcely have imagined. Although Central Park was later carved out of the grid to provide green space, the basic rectangular network continues to shape the daily flow of life in the city.

Suppose the writer's goal had been to write an essay that traces the transition of New York City from a chaotic trading post to a global financial capital. Would this essay accomplish this goal?
