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.

The twenty-hour rule proposes that years of practice are not needed to become skilled at a new activity. Only about twenty hours of effort are needed to reach a ①worthless level. Unlike theories claiming true mastery requires ten thousand hours, this rule targets a more ②modest goal. That goal is simple competence for everyday use. According to supporters, practicing any new skill produces the ③fastest visible improvement, since a beginner has room to grow. Advocates emphasize that the twenty hours must be ④deliberate and focused, broken into short daily sessions rather than one long stretch. The hours should be aimed at fixing weaknesses rather than ⑤repeating what one already knows.

ESG management refers 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 managed ①carelessly and sustainably over the long term. Recently, however, many corporations have learned to boost their ESG scores without ②genuinely transforming their operations. Some firms publish glossy reports filled with impressive statistics while their actual carbon emissions barely decline, exploiting the fact that ESG evaluation systems still lack ③consistent global standards. This gap between appearance and substance has led critics to demand stricter, more ④transparent criteria for measuring 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 ⑤detailed disclosures instead of trusting labels alone.

Browsing an online store today often means chatting with an AI assistant that asks a few quick questions, such as budget or intended use, before suggesting a short list of products ①tailored to the answers. Unlike a static list of best-sellers, this assistant can adjust its suggestions on the spot, responding to follow-up questions the way a knowledgeable salesperson might in a physical store. Retailers report that shoppers who use these chatbots tend to ②complete purchases more often and return fewer items, since the guided conversation helps buyers choose products that actually fit their needs. Some shoppers, however, remain ③confident about how personal the questions can feel, wondering how much of that conversation is quietly stored and reused to influence future purchases. Consumer advocates argue that stores should ④clearly explain what happens to this data, rather than ⑤burying the explanation in a lengthy privacy policy that almost no one reads.

When a beverage company launched a new flavor last summer, the marketing team faced a tight budget and needed a creative solution. Instead of relying on expensive television commercials, they designed a simple dance challenge and invited a handful of everyday users to post videos using the product. Within days, thousands of people began recreating the dance and tagging the brand, turning an ordinary product launch into a viral trend. The company barely spent any money on production, yet the challenge reached millions of viewers across multiple platforms. Encouraged by this success, other brands quickly attempted similar challenges, though many failed to generate the same excitement. Researchers later explained that the original challenge succeeded because it felt spontaneous and fun rather than obviously commercial. This case demonstrates that ___________.

As more businesses move their operations online, cyberattacks have become one of the most serious threats facing modern companies. In response, demand for cybersecurity professionals has surged across nearly every industry. Despite this expansion, experts estimate that ___________, largely because the number of qualified applicants has not kept pace with rapidly increasing demand. This shortage suggests that cybersecurity will remain a promising career path for years to come.

For decades, athletes were taught to stretch a muscle and hold the position before any competition, believing that this practice alone would prevent injury. (A) Recent research, however, has complicated that assumption, since static stretching can actually reduce a muscle's ability to generate explosive force immediately afterward. (B) Dynamic stretching, by contrast, involves controlled, repeated movement through a joint's full range of motion and appears to prepare muscles for activity without this weakening effect. (C) As a result, many coaches now recommend saving static stretching for after a workout while reserving dynamic movements for the warm-up period before intense effort begins.

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.

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.

Some schools have begun asking students to submit an early draft alongside the final version, specifically to preserve evidence of a student's own original voice. Highlighting an awkward sentence and instantly seeing three smoother alternatives has become a routine part of writing for many students, thanks to AI writing assistants built into word processors and browsers. ( ① ) These tools check grammar and spelling, of course, but the more advanced versions go further, suggesting clearer phrasing, flagging repetitive words, and even adjusting tone to sound more formal or more casual depending on the purpose. ( ② ) Teachers generally welcome the grammar and spelling support, since it frees up class time to focus on argument and structure rather than comma placement. ( ③ ) Concerns grow, however, around the tone and phrasing suggestions, which can gradually nudge every student's writing toward a similar, polished style. ( ④ ) This makes it harder to tell an individual voice from a suggestion generated by the same underlying model. ( ⑤ )
