Athletes preparing for major endurance events sometimes ①trains for weeks at high altitude, where the air contains less oxygen than at sea level, in hopes of gaining a physiological edge once they return to compete at lower elevations. In this thin air, the body responds by producing more red blood cells, ②which carry oxygen more efficiently through the bloodstream to working muscles. When these athletes return to sea level, where oxygen is more abundant, their blood ③retains this elevated capacity for a limited period, potentially translating into improved endurance performance. However, the benefits of altitude training are far from guaranteed, since individual athletes respond quite differently to the same conditions, and some experience excessive fatigue that ④undermines the very training they hoped to complete. Many elite programs therefore follow a strategy known as live high, train low, in which athletes sleep at altitude to stimulate blood adaptations but perform intense workouts at lower elevation ⑤to maintain quality and intensity.

Advertisements often rely on subtle psychological techniques ①that persuade viewers without their conscious awareness. One common method, known as social proof, shows images of many people ②using or enjoying a product, suggesting that its popularity guarantees quality. Another technique appeals to authority, ③featuring experts or professionals endorsing a product to make it seem more credible. Repetition also plays a significant role, since seeing the same advertisement multiple times increases familiarity, ④which people often mistake for reliability. Researchers studying consumer behavior have found that viewers who understand these techniques ⑤is less easily influenced by them.

As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions ①have emerged about how that information should be handled. Employees who work with big data now face responsibilities ②that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. Some argue that strict regulations should govern data collection, even if such rules ③slow innovation and increase costs for businesses. Others insist that self-regulation within companies, guided by clear ethical training, can ④protects consumers just as effectively without stifling progress. Universities have begun adding data ethics courses to computer science programs, ⑤recognizing that future employees will need to balance innovation with responsibility.

ESG management ①refers to a company's efforts to consider Environmental, Social, and Governance factors alongside profit when making business decisions. Investors increasingly rely on ESG ratings to judge whether a company is ②managed responsibly and sustainably over the long term. Recently, however, many corporations have learned to boost their ESG scores without genuinely transforming their operations. Some firms publish glossy reports ③filled with impressive statistics while their actual carbon emissions barely decline, exploiting the fact that ESG evaluation systems still lack consistent global standards. This gap between appearance and substance has led critics to demand stricter, more transparent criteria for ④measuring corporate responsibility. Genuine ESG management, in contrast, requires measurable targets, independent audits, and long-term accountability rather than one-time donations or attractive slogans. Investors who wish to identify truly responsible companies should therefore examine detailed disclosures instead of ⑤trust labels alone.

Climate scientists frequently warn about tipping points, thresholds beyond which a small additional change ①triggers a large, often irreversible shift in the climate system. Unlike gradual warming, which unfolds steadily over decades, crossing a tipping point can produce dramatic consequences within a short period. For instance, as Arctic ice melts, it exposes darker ocean water that ②absorb more sunlight than reflective ice, accelerating further melting in a self-reinforcing cycle. Similarly, scientists worry that a major ocean current, which currently ③redistributes heat across the planet, could slow dramatically if enough freshwater from melting glaciers dilutes the surrounding seawater. Once such thresholds are crossed, ④restoring the original balance may become nearly impossible, even if emissions are later reduced. Therefore, researchers argue that preventing these transitions ⑤matters more than merely slowing average temperature increases.

Only a decade ago, translation apps produced sentences so ①awkward that users often laughed at the results rather than trusting them. Today, many of these apps rely on neural networks that analyze entire sentences at once, capturing context instead of translating word by word. This shift has made everyday tasks such as reading a foreign menu or chatting with an overseas friend remarkably ②chaotic. Frequent travelers now point their phone cameras at street signs and receive an ③instant translation overlaid on the screen. Even so, the technology still struggles with humor, sarcasm, and cultural nuance, areas where a single wrong word can ④completely change the intended meaning. For this reason, professional translators argue that these apps are best treated as a helpful ⑤starting point rather than a final, polished result.

Years ago, a small shoe company struggled to compete with larger, well-funded rivals in the market. Its products were ①solid, but customers rarely ②remembered the brand after a single purchase. Sales slowly ③decreased as people felt they were supporting something meaningful rather than simply buying a product. Other companies noticed this shift and began crafting their own narratives, hoping to create similar ④emotional connections. Eventually, the founder realized that a compelling story, told honestly, could turn ordinary customers into ⑤loyal supporters.

The growing presence of AI in creative fields has sparked lively discussion among artists and critics alike. (A) In contrast, some artists worry that relying too heavily on such tools may weaken the value placed on original human creativity. (B) Many artists have embraced AI as a way to explore new styles quickly and overcome creative blocks. (C) Given these opposing views, most experts now agree that AI works best as a partner rather than a replacement for human creators.

주어진 문장: This feeling is not simply nervousness about being alone, but a specific condition that researchers have begun to study closely. Many people feel a sudden wave of anxiety when their smartphone battery is nearly dead or they have left it at home. ( ① ) This intense discomfort, known as nomophobia, is short for "no-mobile-phone phobia," a term describing the fear of losing connection to one's phone. ( ② ) Nomophobia involves physical symptoms, including a racing heart, sweating, and restlessness, whenever a person cannot check messages or social media. ( ③ ) Researchers explain that this fear develops because smartphones have become tightly linked to social belonging; missing a notification can feel like being cut off from friends. ( ④ ) For example, some students check their phones dozens of times an hour, even during class, just to confirm nothing important has been missed. Therefore, experts suggest gradually reducing phone checks to weaken this anxious dependence. ( ⑤ ) Recognizing nomophobia as a real psychological pattern is the first step toward a healthier relationship with technology.

주어진 문장: Some researchers even suggest that painting rooftops white could further help reflect sunlight away from buildings. On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. ( ① ) This phenomenon, known as the urban heat island effect, occurs when cities retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. ( ② ) Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling. ( ③ ) Tall buildings packed closely together also block wind, trapping warm air within narrow streets. ( ④ ) In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does. ( ⑤ )
