The metaverse, a network of interconnected virtual worlds, has begun ①generate job opportunities that did not exist just a few years ago. Companies now hire virtual world designers who build digital environments ②where users can socialize, shop, or attend events. Avatar designers create digital identities ③that represent users within these spaces, blending artistic skill with technical programming knowledge. Some analysts remain skeptical, ④pointing out that the metaverse has not yet attracted the massive user base that early predictions promised. Nevertheless, major companies continue ⑤investing heavily in this technology.

Feed an AI music program a mood, a tempo, and a rough genre, and within seconds it can generate a complete instrumental track, ①ready to be dropped under a video or used as background music for a small business. The software has studied thousands of existing songs, ②learning which chord progressions and rhythms tend to sound pleasant together, and it recombines these patterns into something new rather than ③copying any single source directly. For independent creators who cannot afford a composer or expensive licensing fees, this has been a genuine breakthrough. Professional musicians, however, remain divided. Some welcome the tool as a quick way to sketch ideas before ④refine them by hand, while others worry that a flood of AI-generated background music could quietly push human composers out of smaller, lower-budget projects, the very jobs many musicians once ⑤relied on to build a career.

Remote work has moved from a rare privilege to a common practice for millions of employees worldwide. Many companies that once required workers ①to commute daily now allow them to complete tasks from home. Supporters argue that remote work increases productivity, since employees avoid long commutes and ②distracting office environments. It also allows companies to hire talented people regardless of where they live, ③widening the pool of candidates. Critics, however, worry that remote work weakens teamwork and ④make it harder for new employees to learn from experienced colleagues. Without regular face-to-face interaction, some workers feel isolated and ⑤struggle to build strong professional relationships.

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.

Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that willpower functions like a muscle that gradually ①strengthens after repeated use. According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same ②limited mental resource. As this resource becomes ③depleted throughout the day, later decisions require more effort and are more likely to fail. For instance, someone who exercises discipline avoiding distractions all morning may ④struggle to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help ⑤restore this depleted resource.

Mira had lived in a coastal village since birth, watching the tide creep closer to her family's doorstep every year. When the sea finally swallowed the rice paddies that had fed her village for generations, her parents decided that staying was no longer possible. Together with many neighbors, they packed what little they could carry and moved inland, becoming what experts now call climate migrants, _______________. This term, rarely used a decade ago, has become increasingly common as extreme weather displaces communities worldwide. Mira missed her old house terribly, yet she slowly began to build a new life in the crowded city, learning to adapt just as her ancestors once had. International organizations, however, still struggle to agree on how to protect people like her, since climate migrants are not officially recognized as refugees under current law.

Airlines and other companies often invite customers to pay a small extra fee to offset the carbon released by their trips. (A) As a result, purchasing an offset can become a convenient way to avoid making harder, more meaningful changes to one's actual carbon footprint. (B) This option relies on carbon offsets, credits that fund projects like tree planting or renewable energy in exchange for supposedly canceling out one's own emissions. (C) Critics point out, however, that many such projects would have occurred regardless of the funding, meaning the offset achieves little real, additional benefit.

After a viewer finishes an episode, a streaming service rarely leaves the choice of what to watch next entirely up to chance. (A) The system is not without drawbacks, however, since favoring titles similar to what a viewer already enjoys can quietly narrow someone's exposure to unfamiliar genres, directors, or cultures. (B) Instead, a recommendation algorithm compares that viewer's habits with patterns drawn from millions of other users, then ranks thousands of titles in order of predicted interest. (C) This approach keeps viewers engaged far longer than a simple list of new releases ever could, which is precisely why streaming companies invest so heavily in refining it.

This process, though it may sound simple, triggers a remarkable series of adaptations throughout the cardiovascular system. Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, strengthens the heart by forcing it to pump larger volumes of blood with each beat. ( ① ) Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, meaning it can deliver the same amount of oxygen to working muscles while beating fewer times per minute. ( ② ) This adaptation explains why trained athletes often have a much lower resting heart rate than sedentary individuals of the same age. ( ③ ) Beyond the heart itself, aerobic activity encourages the body to build new capillaries within muscle tissue, improving the delivery of oxygen and nutrients at a cellular level. ( ④ ) Researchers have also found that regular aerobic exercise reduces inflammation throughout the body and improves the way cells respond to insulin. ( ⑤ )

주어진 문장: This unexpected combination of skills fascinated him more than he had expected. When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers belonged only to a handful of government scientists. ( ① ) By the time he entered university, however, the space industry had changed dramatically, as private companies began launching satellites and building reusable rockets. ( ② ) Daniel studied aerospace engineering, drawn to the idea that space exploration was no longer limited to a few national agencies. ( ③ ) During an internship, he helped design a small satellite intended to monitor crop health from orbit, a project that combined engineering with agricultural science. ( ④ ) He realized that the space industry now needed not only pilots and engineers but also data analysts, technicians, and even lawyers familiar with international space regulations. ( ⑤ ) After graduation, Daniel joined a startup developing lunar landing equipment, a job that barely existed when he first imagined his future career.
