A growing number of health apps now track steps, sleep, and heart rate throughout the day, ①quietly 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 ②experiencing 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 ③feel like a genuine safety net. Doctors caution, however, that these apps ④are 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 ⑤being just as risky as ignoring a warning altogether.

Have you ever noticed your mood ①shifting after scrolling through a friend's gloomy post online? This phenomenon, known as emotional contagion, ②refers to the tendency of one person's feelings to spread to others nearby, almost like a cold passing between classmates. However, researchers have discovered that emotional contagion also occurs online, where only text or images ③are exchanged, without any physical presence at all. For instance, when someone posts a negative comment beneath a cheerful photo, the comments that follow often ④turning noticeably more negative in tone. In contrast, a single kind comment ⑤can shift an entire thread toward positivity within minutes.

Remote work has moved from a rare privilege to a common practice for millions of employees worldwide. Supporters argue that remote work ①decreases productivity, since employees avoid long commutes and distracting office environments. It also allows companies to hire talented people regardless of where they live, ②widening the pool of candidates. Critics, however, worry that remote work ③weakens teamwork and makes it harder for new employees to learn from experienced colleagues. Without regular face-to-face interaction, some workers feel ④isolated and struggle to build strong professional relationships. For these reasons, many experts suggest that the future of work will likely be hybrid, ⑤combining flexibility with occasional in-person collaboration.

Jina used to fill her apartment with items she rarely used, believing that owning more things would make her ①happier. After moving twice within a single year, she grew ②energized from packing boxes filled with clothes she had never worn and gadgets she had forgotten she owned. Gradually, however, she noticed that her small apartment felt ③calmer and easier to manage. She also realized that she spent significantly ④less money once she stopped buying things impulsively to fill emotional gaps. Jina's story reflects a broader trend among young adults who increasingly value experiences and simplicity over ⑤accumulating possessions.

A smart thermostat that learns a family's daily rhythm can lower the temperature automatically before everyone wakes up cold, while smart lights that follow a resident's schedule no longer need to be switched on and off by hand. These small ①conveniences rest on a shared foundation: sensors collect data about temperature, motion, and light throughout the home, and an algorithm gradually learns which settings match each household's actual habits rather than a factory default. Over months of use, the system becomes noticeably ②better at anticipating needs, often adjusting settings moments before a resident would have reached for a switch. Yet convenience comes with a trade-off that many households ③overlook. Every one of these small adjustments depends on constant data collection, meaning that a detailed record of daily habits is quietly being ④stored somewhere ⑤beyond their immediate control, giving residents full and constant access to exactly how it is used.

Every day, email providers quietly block billions of unwanted messages before they ever reach a user's inbox. The filter examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks. What makes the system effective is that it keeps learning after launch: whenever a user marks a message as spam, that action becomes new training data, sharpening the filter's future decisions. This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. As a result, _______________.

Only a decade ago, translation apps produced sentences so awkward that users often laughed at the results. 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 smooth. Even so, the technology still struggles with humor, sarcasm, and cultural nuance, so that _______________. For this reason, professional translators argue that these apps are best treated as a helpful starting point rather than a final, polished result.

Jihun wanted to start stretching every day but kept forgetting no matter how many notes he left himself. (A) After a month, he no longer needed to think about it, because the smell of coffee alone reminded him to stretch. (B) He decided to try habit stacking by connecting the new habit to something he already did without fail each morning. (C) Since he never skipped making coffee before school, he began stretching for five minutes while the coffee machine ran.

주어진 문장: This gap between image and reality is precisely what makes the practice so misleading. Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims turn out to be misleading. ( ① ) This practice, known as greenwashing, occurs when a business spends more effort marketing its products as eco-friendly than actually reducing environmental harm. ( ② ) A company might launch a recycled-packaging line while continuing to pollute rivers through its main factories, creating a false impression of genuine change. ( ③ ) Such tactics deceive well-intentioned consumers who wish to shop responsibly but lack the tools to verify corporate claims. ( ④ ) In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, allowing outsiders to check their progress. ( ⑤ ) Therefore, shoppers should look beyond vague labels like green or natural and instead search for recognized certifications, transparent reports, and measurable targets. Without such scrutiny, greenwashing will keep flourishing, undermining public trust and slowing the broader shift toward an economy that truly protects the planet.

주어진 문장: At first glance, this seems to suggest that Dunbar's theory no longer applies in the digital age. Anthropologist Robin Dunbar proposed a concept now known as Dunbar's number, suggesting that human beings can only maintain about one hundred fifty stable social relationships at any given time. ( ① ) This limit, he argued, comes from the size of the human brain, which restricts how many meaningful connections a person can cognitively manage. ( ② ) In contrast, many social media users today have hundreds or even thousands of online friends and followers, a number far exceeding what Dunbar's research predicts. ( ③ ) However, having numerous digital contacts does not necessarily mean that all of these relationships are close or emotionally supportive. ( ④ ) Most users, when asked, admit that they interact regularly with only a small fraction of their total followers, while the rest remain largely unnoticed. ( ⑤ ) Therefore, Dunbar's number reminds us that genuine, lasting relationships require consistent effort and attention, something that a large online network alone cannot provide.
