(1) The Atacama Desert, a plateau in South America, is widely considered the driest nonpolar desert in the world. Stretching along the coast of Chile, its landscape is often compared to that of Mars. The extreme aridity is primarily caused by a double rain shadow effect. To the east, the towering Andes Mountains block precipitation from the Amazon basin, while to the west, the Chilean Coast Range prevents moisture from the Pacific Ocean from reaching the desert interior. Furthermore, a cold offshore ocean current called the Humboldt Current creates a coastal inversion layer of cool air, which inhibits the formation of rain-producing clouds. (2) For years, scientists believed that complex life could not survive in the Atacama's hyper-arid core. It was thought that the combination of intense ultraviolet (UV) radiation, high soil salinity, and near-total lack of water made the environment sterile. However, recent discoveries have challenged this assumption. Researchers have found pockets of microbial life, such as bacteria and archaea, living within rocks (endoliths) and deep beneath the salty soil. These resilient organisms have developed unique strategies to conserve water and protect themselves from UV radiation, offering clues as to how life might exist on other planets. (3) The same conditions that make the Atacama inhospitable to most life forms make it one of the premier locations on Earth for astronomical observation. The high altitude, clear skies, and lack of light pollution create exceptionally transparent atmospheric conditions. Major international observatories, such as the Atacama Large Millimeter/submillimeter Array (ALMA), are situated here. These telescopes can peer deep into the universe, studying the birth of stars and galaxies with a clarity that is impossible to achieve in most other parts of the world. The Atacama, therefore, serves as a natural laboratory for studying both the limits of life on Earth and the vastness of the cosmos beyond.

Which of the following is presented in the passage as a feature of the Atacama Desert?

(1) In a world that often values perfection and disposability, the Japanese art of kintsugi, or "golden joinery," offers a profound alternative. Kintsugi is the centuries-old practice of repairing broken pottery with a special lacquer dusted or mixed with powdered gold, silver, or platinum. Rather than trying to hide the damage, this method accentuates the cracks and repairs, making them a visible and celebrated part of the object's history. The result is a piece that is often considered more beautiful and valuable than it was before it was broken. (2) The process of kintsugi is meticulous and requires great patience. First, the broken pieces are carefully reassembled and glued together using urushi, a lacquer derived from the sap of the Chinese lacquer tree. This natural adhesive is extremely durable but can take weeks or even months to cure completely. Once the initial bond is set, the cracks are filled with a mixture of lacquer and a binding agent like clay powder. Finally, before the last layer of lacquer is fully dry, a fine powder of precious metal is applied to the seams, creating the distinctive golden lines. (3) The philosophy behind kintsugi is rooted in the Japanese concept of wabi-sabi, which embraces imperfection and transience. It sees breakage and repair not as something to be disguised, but as an integral part of an object's life story. This perspective encourages acceptance of flaws and views them as sources of unique beauty. In a broader sense, kintsugi can be seen as a metaphor for human resilience; it suggests that our own scars and past traumas, when acknowledged and integrated, can make us stronger and more interesting. The repaired object is a testament to survival, highlighting its journey through time and adversity.

The passage indicates that the kintsugi repair process is

Based on the passage, which statement accurately describes a reason for the Atacama Desert's extreme dryness?

(1) In the 15th and 16th centuries, spices like cloves, nutmeg, and black pepper were commodities of extraordinary value, in some cases worth more than their weight in gold. These spices, native to remote islands in Asia, were not merely flavor enhancers; they were essential for preserving food in an era before refrigeration, masking the taste of salted or slightly spoiled meats, and were also prized for their use in medicines and perfumes. The immense demand in Europe, coupled with the perilous overland trade routes controlled by various middlemen, made spices astronomically expensive. (2) The quest to find a direct sea route to the "Spice Islands" (the Moluccas in modern-day Indonesia) was a primary driver of the Age of Exploration. European monarchs and merchants were eager to bypass the traditional land routes, which were long, dangerous, and subject to heavy taxes by the Venetian and Ottoman empires. Visionaries like Christopher Columbus and Vasco da Gama proposed daring voyages into uncharted waters. While Columbus famously miscalculated and landed in the Americas, Vasco da Gama successfully rounded Africa's Cape of Good Hope in 1498, establishing a direct maritime link to India and, subsequently, to the sources of the spice trade. (3) Da Gama's voyage fundamentally altered global trade and power dynamics. The Portuguese quickly established a monopoly over the sea-based spice trade, building fortified trading posts throughout the Indian Ocean. This broke the centuries-old Venetian dominance and shifted the center of European commerce from the Mediterranean to the Atlantic. The immense wealth generated fueled further exploration and colonization, but it also brought about intense conflict as other European powers, such as the Dutch and English, sought to challenge Portugal's control and claim their own share of the lucrative trade. The world, in a sense, was redrawn by the pursuit of these small, dried seeds and barks.

What was one consequence of the establishment of a sea route to the Spice Islands, according to the passage?

A pillar stands against the gray, A solitary, patient eye. It sweeps a beam to guide the way, Where ships on troubled waters lie.

It does not dread the lashing spray, Nor flinch when winds and tempests cry. It measures night and passing day, Beneath a vast and churning sky.

A silent keeper, stark and tall, It offers light, a steady friend. A constant answer to the call Of those who on its gleam depend.

Which of the following phrases from the poem best supports the idea that the lighthouse is resilient?

(1) The city hummed with a rhythm Leo was still trying to learn. Back home, the loudest sounds were the wind in the pines and the distant lowing of cattle. Here, the symphony was one of sirens, the rumble of subway trains beneath his feet, and a thousand overlapping conversations in languages he didn't recognize. His uncle, Mark, navigated the crowded sidewalks with an effortless grace, weaving through pedestrians as if he were part of the current. "You'll get used to it," Mark had promised, clapping him on the shoulder. "Give it a week, and you won't even notice the noise." (2) Leo wasn't so sure. He felt like a ship in a bottle, carefully placed in a scene where he didn't quite fit. Everything was vertical—the buildings scraping the sky, the impossibly tall cranes, even the ambitions of the people who rushed past him, their eyes fixed on some unseen destination. At a street corner, a vendor was roasting chestnuts, and the smoky, sweet smell was a sudden, welcome anchor in the sensory overload. It was a scent he knew, a small piece of familiarity in the vast, overwhelming newness. (3) Mark pointed to a towering glass structure. "That's my office building. We're almost there." Leo tilted his head back, his neck craning to see the top, which seemed to disappear into the low-hanging clouds. He thought of his father's workshop, a low-slung wooden building with wide-open doors and the scent of sawdust. The contrast was dizzying. Mark was offering him an opportunity, a summer internship that everyone said he'd be foolish to refuse. But as he stood there, dwarfed by the sheer scale of it all, Leo wondered if he was built for a world of such heights.

(1) The Great Barrier Reef, located off the coast of Queensland, Australia, is the world's largest coral reef system. Composed of over 2,900 individual reefs and 900 islands, it stretches for over 2,300 kilometers and is so vast that it can be seen from outer space. This living structure is built by billions of tiny organisms known as coral polyps. These polyps secrete calcium carbonate to form a hard skeleton, which accumulates over generations to create the massive and complex reef structures. (2) The reef is a hotspot of biodiversity, providing a home to a staggering array of marine life. It supports thousands of species of fish, mollusks, sponges, and crustaceans, as well as larger animals like dolphins, whales, sea turtles, and sharks. The complex nooks and crannies of the reef offer shelter and breeding grounds for countless organisms. This intricate web of life depends on a delicate balance of environmental conditions, including water temperature, clarity, and chemical composition. (3) A crucial component of the reef ecosystem is the symbiotic relationship between coral polyps and microscopic algae called zooxanthellae, which live within the corals' tissues. The algae provide the coral with up to 90 percent of its energy through photosynthesis, and in return, the coral provides the algae with a protected environment and the compounds they need. This partnership is also responsible for the vibrant colors for which corals are famous. (4) However, this vital relationship is under threat. When corals are stressed by changes in conditions, such as rising ocean temperatures, they expel the zooxanthellae. This process is known as coral bleaching. While bleached coral is not dead, it is left without its primary source of food and is more susceptible to disease and mortality. Widespread bleaching events have become more frequent and severe, posing a significant threat to the long-term survival of the Great Barrier Reef and the rich biodiversity it supports.

(1) The Rosetta Stone is one of the most famous artifacts in the world, yet its significance lies not in its beauty but in the text carved upon its surface. Discovered in 1799 by French soldiers in the Egyptian village of Rosetta, the stone is a fragment of a larger stele. It contains a decree issued at Memphis, Egypt, in 196 BC on behalf of King Ptolemy V. What makes the stone unique is that the decree is inscribed in three different scripts: Hieroglyphic, the sacred script of ancient Egypt; Demotic, the common script of the time; and Ancient Greek, the language of the ruling class. (2) For centuries, the meaning of Egyptian hieroglyphs had been a complete mystery. Scholars could see the intricate symbols on temples and papyri, but the knowledge of how to read them had been lost for over 1,400 years. The Rosetta Stone provided the critical key to this puzzle. Since the three scripts recorded the same text, scholars could use the known Ancient Greek text as a guide to decipher the two unknown Egyptian scripts. It was assumed, correctly, that the texts were direct translations of one another. (3) The final breakthrough came in 1822, thanks to the painstaking work of the French scholar Jean-François Champollion. He built upon the work of others, such as the English physicist Thomas Young, but it was Champollion who correctly deduced that the hieroglyphic script was not purely symbolic but a complex combination of alphabetic, syllabic, and determinative (ideographic) signs. He realized that certain hieroglyphs, enclosed in an oval shape called a cartouche, spelled out the names of royal figures like Ptolemy. This crucial insight allowed him to unlock the phonetic values of many signs, and from there, the entire system of hieroglyphic writing began to unfold, opening a direct window into the world of ancient Egypt.

(1) The old suitcase sat open on my bed, a hollow mouth waiting to be filled. For a week, I had circled it, picking up a book only to put it down, folding a shirt and then unfolding it. Moving to the city was supposed to be an adventure, the thrilling next chapter Liam had so enthusiastically described. He spoke of bustling streets, endless opportunities, and a life vibrant with energy. He couldn't understand my hesitation. "It's just a place, Elara," he'd said, his voice laced with a gentle impatience that was becoming all too familiar. (2) But for me, it wasn't "just a place." It was the absence of this place: the scent of rain on dry soil, the silhouette of the oak tree against the sunset, the low hum of the cicadas that had been the soundtrack to every summer of my life. These were the things I was packing away, not just my clothes and books. I walked to the window and looked out at the rolling fields, now washed in the soft gold of late afternoon. Mrs. Gable's dog, Buster, was chasing a butterfly in her yard, a small, familiar drama. (3) Liam saw a dead-end town; I saw a tapestry of moments. He saw quiet; I heard peace. He saw a beginning in the city, but all I could feel was the weight of this ending. I picked up a small, smooth stone from my windowsill, one I had found by the creek when I was ten. Its cool weight was a comfort in my palm. How could I explain that leaving felt like tearing a page out of my own story? I placed the stone carefully in a side pocket of the suitcase. It was a small, silent rebellion, a piece of home I refused to leave behind.

Which statement is supported by the passage's description of Elara's feelings?
