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 ①to 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. Because participants created the content themselves, viewers found the videos far more entertaining than a traditional advertisement would have been. The company barely spent any money on production, yet the challenge ②reach millions of viewers across multiple platforms. Researchers later explained that the original challenge ③succeeded because it ④felt spontaneous and fun rather than obviously commercial. This case demonstrates that authenticity, not advertising budget, often ⑤determines whether a campaign truly resonates with audiences.

Psychologists have long studied a mechanism called the variable reward schedule, in which rewards ①arrive unpredictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor ②how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone ③is checked, regardless of whether the result is disappointing or thrilling. Consequently, users often refresh their feeds compulsively, ④hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies deliberately designed notification systems using insights borrowed from gambling research, rather than ⑤stumble upon them by accident.

Military researchers have developed weapons systems capable of identifying and engaging targets without a human pressing the final button, a prospect that has ① alarmed arms control experts for over a decade. Advocates within defense agencies argue that autonomous systems can react faster than any human operator and may even ② reduce casualties by removing fear and fatigue from split-second decisions. Human rights organizations counter that removing a person from the final decision strips away moral responsibility at the exact moment it matters most, since a machine cannot be held ③ accountable in any meaningful sense. Diplomatic negotiations toward an international treaty have repeatedly ④ succeeded, partly because military powers disagree on how to define autonomy precisely enough to regulate it. Meanwhile, the underlying technology continues to ⑤ advance regardless of whether the diplomacy meant to govern it keeps pace.

When Mina was a freshman, she often spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study in which children could eat one marshmallow ①immediately or wait for two. Researchers found that children who waited ②longer showed better academic performance and self-control years later. This ability to ③resist an immediate reward in favor of a larger future one is known as delayed gratification. Inspired by the study, Mina began saving half of her allowance each week instead of spending it all on snacks. At first, resisting small purchases felt surprisingly ④easy, especially when her friends were eating out. After three months, however, she had ⑤saved enough to buy a bicycle she had wanted for over a year.

As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions have emerged about how that information should be handled. Employees who work with big data now face ①minimal responsibilities that 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 ②slow innovation and increase costs for businesses. Others insist that self-regulation within companies, guided by clear ethical training, can protect consumers just as ③effectively without stifling progress. Most experts agree that professionals handling sensitive data must be trained not only in technical skills but also in ethical ④decision-making. Universities have begun adding data ethics courses, recognizing that future employees will need to ⑤balance innovation with responsibility.

Physical education class often feels like the one period of the day when students can finally move freely, which sometimes leads them to skip the warm-up routine that teachers insist on before any real activity begins. Cold muscles, however, are noticeably less flexible than warmed ones, and _______________. Coaches often compare an unwarmed muscle to a cold rubber band that snaps rather than stretches under sudden pressure.

Behavioral economists use the term temporal discounting to describe how people undervalue future rewards simply because those rewards are not immediate. This tendency explains why a student might choose to watch videos tonight rather than study for an exam that remains several weeks away, even though studying offers a greater long-term benefit. A distant reward, no matter how valuable, feels psychologically smaller than a small reward available right now. This bias contributes to procrastination, since future consequences rarely feel urgent enough to motivate immediate action. To counter this tendency, students should convert distant goals into smaller, near-term milestones that feel more emotionally real. Setting weekly checkpoints rather than a final deadline can make future benefits feel closer and more concrete. Teachers and parents should provide immediate, meaningful feedback, since ___________.

For years, a small riverside village had suffered from flooding that grew worse with each passing summer. (A) In addition, several families whose houses stood in the most vulnerable areas relocated to higher ground, and the village installed an early warning system that sent alerts to residents' phones whenever river levels rose dangerously fast. (B) When a powerful storm struck three years later, the new measures proved effective, and the village suffered only minor damage instead of the devastating losses it had previously faced, becoming a model for neighboring communities. (C) Frustrated residents eventually decided to pursue climate adaptation, adjusting their infrastructure and habits to reduce the damage caused by increasingly unpredictable weather, and engineers began by widening the drainage canals surrounding the village so that excess rainwater could flow away more efficiently.

주어진 문장: This explains why progress often feels rapid and motivating during the earliest days of learning something new. The twenty-hour rule proposes that years of practice are not needed to become skilled at a new activity. ( ① ) Only about twenty hours of effort are needed to reach a useful level. Unlike theories claiming true mastery requires ten thousand hours, this rule targets a more modest goal. That goal is simple competence for everyday use. ( ② ) According to supporters, practicing any new skill produces the fastest visible improvement, since a beginner has room to grow. ( ③ ) Someone learning guitar can typically strum simple chords and follow a basic song within twenty hours of daily practice. ( ④ ) Likewise, a language learner may soon order food or ask directions without years of formal study. ( ⑤ ) Advocates emphasize that the twenty hours must be deliberate and focused, broken into short daily sessions rather than one long stretch. The hours should be aimed at fixing weaknesses rather than repeating what one already knows.

There is also a quieter cultural cost that rarely appears in productivity reports. Sensors buried in the soil now report moisture levels in real time, drones survey entire fields for signs of disease within minutes, and automated systems adjust irrigation without a farmer ever walking the rows. ( ① ) For large operations with the capital to invest, these tools have measurably increased yields while reducing water waste. ( ② ) Smaller family farms, however, often cannot afford the upfront cost of this equipment. ( ③ ) Some worry that the gap between high-tech and traditional operations will only widen as the technology advances further. ( ④ ) Generations of farming knowledge, passed down through direct observation of soil, weather, and crops, risk being replaced by dashboards and automated alerts. ( ⑤ )
