A growing number of health apps now track steps, sleep, and heart rate throughout the day, ① quietly building a detailed picture of a user's physical condition without requiring a single visit to a doctor's office. By comparing this stream of data against patterns drawn from millions of other users, the app's algorithm can flag early warning signs, such as an irregular heartbeat, long before the person ② experiencing it would have noticed anything unusual on their own. For people living far from specialists or unable to afford frequent checkups, this kind of constant monitoring can ③ feel like a genuine safety net. Doctors caution, however, that these apps ④ are designed to detect patterns, not to diagnose illness, and that a worried user should always confirm any alarming reading with a professional. Treating a wellness app as a substitute for medical expertise, they warn, can ⑤ being just as risky as ignoring a warning altogether.

The metaverse, a network of interconnected virtual worlds, has begun to generate job opportunities that did not exist just a few years ago. Meanwhile, virtual event planners organize concerts, conferences, and product launches entirely within online platforms, reaching audiences that would be impossible to gather in person. Some analysts, however, ___________, noting that the metaverse has not yet attracted the massive user base that early predictions promised. Nevertheless, major companies continue investing heavily in this technology.

Behavioral economists use the term status quo bias to describe a tendency to prefer the present situation over a new alternative, even when the alternative would bring greater benefits. This bias helps explain why many households hesitate to switch to renewable energy, such as installing solar panels on their roofs. Although solar panels can lower electricity bills over time, homeowners often stick with their current power source because it feels safe and requires no immediate effort. In contrast, switching demands research, upfront cost, and trust in unfamiliar technology, all of which can seem risky compared with doing nothing. For example, a neighborhood association might repeatedly postpone a vote on shared solar panels, not because the plan is flawed, but because members are reluctant to leave their routine. Therefore, boosting renewable adoption may depend less on proving its advantages and more on _______________.

Jiho's path into entrepreneurship began almost by accident, far from the corporate career his parents had imagined for him. (A) Despite warnings from relatives who considered the plan too risky, Jiho and his teammates decided to delay job applications and pursue the idea further. (B) A class project he joined during his final year gradually evolved into something more serious, as restaurants began placing regular orders through their prototype. (C) That decision eventually paid off, as the team secured a small investment after nearly failing twice.

The growing sophistication of cyberattacks has transformed cybersecurity into one of the most in-demand career fields. (A) Universities have responded to this trend by launching specialized degree programs focused entirely on cybersecurity. (B) As a result, businesses across nearly every industry now compete to hire qualified security professionals. (C) Hackers today target organizations of every size, from small retailers to major financial institutions.

주어진 문장: Fortunately, this cycle is not impossible to reverse. An echo chamber refers to an online environment where people are mainly exposed to opinions that already match their own beliefs. ( ① ) This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. ( ② ) As a result, individuals inside an echo chamber rarely engage with viewpoints that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. ( ③ ) For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, having never seriously considered its arguments. ( ④ ) Political polarization, a significant issue in many countries today, is often linked to this pattern of selective exposure. ( ⑤ ) Breaking out of an echo chamber requires deliberately seeking information from diverse sources, even when those sources present uncomfortable or unfamiliar ideas.

주어진 문장: Even small purchasing decisions, they argue, can accumulate into meaningful pressure on how companies operate. Value-based consumption refers to the practice of spending money on products or experiences that align with a person's personal beliefs, even if cheaper alternatives exist. ( ① ) Rather than simply seeking the lowest price, value-conscious consumers consider factors such as labor conditions, environmental impact, and community benefit before making a purchase. ( ② ) Some critics dismiss this approach as impractical, arguing that most people cannot afford to prioritize ethics over affordability in daily life. ( ③ ) However, supporters point out that value-based spending does not require constant sacrifice; it often means buying fewer, higher-quality items rather than accumulating cheap goods that wear out quickly. ( ④ ) This shift also encourages companies to improve their practices, since consumer demand increasingly rewards transparency and responsibility. ( ⑤ ) For example, a clothing brand that openly shares its supply chain information may attract loyal customers willing to pay slightly more.

주어진 문장: This limitation means the technology has not yet fully replaced conventional factories. Three-dimensional printing technology is changing how products are designed and manufactured across many industries. ( ① ) Unlike traditional manufacturing, which often requires expensive molds and long production times, 3D printers can create complex objects directly from digital files within hours. ( ② ) This flexibility allows companies to produce small batches of customized products without the massive costs typically associated with mass production. ( ③ ) Hospitals now use 3D printing to create prosthetic limbs tailored precisely to individual patients, while automakers use it to build lightweight parts. ( ④ ) However, experts caution that 3D printing still struggles to match the speed of mass production for extremely large orders. ( ⑤ ) As printing materials improve and machines become faster, the technology is expected to play an increasingly central role in future manufacturing.

None of these explanations, in other words, has to be the whole story. For centuries, dreams have fascinated scientists and philosophers alike, yet no single theory fully explains why the sleeping brain generates such vivid and often bizarre experiences. ( ① ) One prominent idea suggests that dreaming helps the brain process emotional experiences, replaying difficult events in a safe, low-stakes environment so that their emotional intensity gradually fades. ( ② ) Another theory proposes that dreams serve a more practical function, allowing the brain to rehearse responses to threats without any real danger, a kind of nightly simulation that may have offered early humans a survival advantage. ( ③ ) Still other researchers argue that dreaming is simply a byproduct of the brain organizing memories, with vivid imagery arising as the mind sorts through the day's information rather than serving any independent purpose of its own. ( ④ ) Because these theories rest on indirect evidence rather than direct observation of subjective experience, none has been conclusively proven. ( ⑤ ) Many scientists now suspect that dreaming may serve several of these functions simultaneously rather than just one.

주어진 문장: She almost forgot about it by the next week, assuming the habit would not last long. Until last spring, Minji rarely thought twice about tossing a paper cup into the trash after finishing her coffee. ( ① ) Environmental issues seemed distant, something scientists and politicians should handle rather than an ordinary student like her. ( ② ) That changed when her class was assigned a documentary about plastic waste drifting through the ocean, footage she initially expected to find boring. Instead, watching seabirds mistake plastic fragments for food left her strangely unsettled, and she found herself thinking about the assignment long after class ended. ( ③ ) The next morning, almost without deciding to, she slipped her old tumbler into her backpack instead of buying a disposable cup on the way to school. ( ④ ) It felt like a small, meaningless gesture at first. ( ⑤ ) However, as weeks passed, she realized that consistently choosing the tumbler, declining a plastic straw, and reusing a shopping bag were quietly adding up. Small choices, she discovered, become meaningful once repeated.
