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?

Strumming My Way
[1]
Last summer, I decided to learn a new musical instrument. Walking into the local music shop, my eyes immediately bypassed the massive guitars and glossy pianos, landing instead on a small, four-stringed instrument: the ukulele. Its compact size and bright, cheerful color felt welcoming. I bought it on the spot.
[2]
Learning the basic chords was surprisingly easy. Within three days, I could play a simple version of my favorite folk song. The nylon strings were gentle on my fingers, unlike the harsh steel strings of my older brother's acoustic guitar. I practiced on our back porch every evening, enjoying the warm breeze.
[3]
By the end of the summer, I was confident enough to perform a short song at a family barbecue. While my playing was not perfect, the cheerful strums brought smiles to my relatives' faces. This small instrument had opened up a whole new world of musical joy for me, proving that you don't need a massive instrument to make a big impact.
Suppose the writer's goal had been to write an essay that describes the historical origins and development of the ukulele as a traditional Hawaiian instrument. Would this essay accomplish that goal?

In the early nineteenth century, navigating the coastal waters of Europe and North America at night was a perilous endeavor. Existing lighthouses relied on crude metal reflectors and thick glass lenses that absorbed most of the light, casting weak, scattered beams that were barely visible a few miles out. Mariners frequently ran aground because they could not see the warning beacons until it was too late.
[2]
The solution came in 1821 from French physicist Augustin-Jean Fresnel, who designed a revolutionary lens system. Instead of using a single thick, heavy piece of glass, Fresnel assembled a series of concentric glass rings shaped like prisms. These rings bent the light from a central lamp and concentrated it into a single, intense parallel beam. This design allowed the light to travel over twenty miles across the ocean surface, significantly increasing the visibility of the lighthouses.
[3]
Fresnel's invention transformed maritime safety worldwide. Within decades, his lenses were installed in lighthouses across the globe, dramatically reducing the number of shipwrecks and saving countless lives. Even today, despite the advent of modern satellite navigation and radar, many historic lighthouses still employ Fresnel's ingenious design, demonstrating the enduring legacy of his scientific achievement.
Suppose the writer's goal had been to write an essay that describes how a specific scientific innovation directly addressed a historical challenge in transportation safety. Would this essay fulfill that goal?

The Sweet Accident of 1904
During the hot summer of 1904, the St. Louis World's Fair was in full swing, attracting millions of visitors. Among the vendors was Arnold Fornachou, an ice cream seller who was doing a brisk business. The demand for his ice cream was so high that he quickly ran out of clean paper dishes to serve his customers. Without any way to hold the ice cream, his business threatened to grind to a halt.
Directly next to Fornachou's booth was Ernest Hamwi, a Syrian immigrant who was selling zalabia, a waffle-like pastry. Seeing his neighbor's predicament, Hamwi quickly rolled one of his warm, thin waffles into the shape of a cone. He let it cool for a moment so it would harden, and then handed it to Fornachou. Fornachou placed a scoop of ice cream on top of the waffle cone, and the customers loved it.
This spontaneous collaboration marked the birth of the modern ice cream cone. The combination of the cold ice cream and the crispy, edible container solved the vendor's immediate container shortage while creating a lasting culinary sensation. Soon, other vendors at the fair began adopting the idea, cementing the cone's place in popular culture.
Determine whether the following statement is true or false:
Suppose the writer's goal had been to write an essay that describes how a practical problem at the 1904 World's Fair led to the creation of the modern ice cream cone. This goal was successfully met by the essay.

In particular, her discovery of a new genus of sunflower, *Mexianthus*, solidified her legacy in the scientific community.
The writer wants to revise the underlined portion ("brave enough to confront harsh environments") to provide the most specific, concrete details that support the claim that Mexia traveled through challenging and remote terrain. Which choice best accomplishes this goal?
