When Mina was a freshman, she often ①spent her allowance within a few days. Her older cousin told her about the marshmallow experiment, a famous study ②in which children could eat one marshmallow immediately or wait for two. Researchers found that children who waited longer ③shown better academic performance and self-control years later. Inspired by the study, Mina began ④saving half of her allowance each week instead of spending it all on snacks. After three months, however, she had saved enough to buy a bicycle she had ⑤wanted for over a year.

Many companies today advertise their products as environmentally friendly, yet not all of these claims are ①accurate. Consumers, who are increasingly ②concerned about climate change, often trust such claims without questioning them closely. As a result, they may pay ③higher prices for products that are no more sustainable than ordinary alternatives. Genuine environmental efforts, which usually require significant investment and long-term planning, are far more ④costly than simply changing a label. Therefore, governments should establish clear standards that require companies to prove their environmental claims with ⑤unverifiable data.

For most of last year, Junho refreshed his social media feed constantly, ①terrified of missing a party, a trending meme, or gossip among his friends. This restless anxiety, often called FOMO, or the fear of missing out, left him ②relaxed and strangely unsatisfied even after hours of scrolling. One weekend, his phone battery died during a hiking trip, and, to his surprise, he actually ③enjoyed the quiet afternoon without notifications interrupting his thoughts. Curious about this ④unexpected calm, Junho began deleting social apps for a few hours each day. This shift in attitude reflects what psychologists now call JOMO, a mindset that treats disconnection as ⑤freedom rather than loss.

Sociologist Mark Granovetter introduced an idea that seems contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. This happens because strong ties tend to share the same social circles and, therefore, already possess similar knowledge. Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. Social media platforms have made maintaining such connections remarkably easier, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms _______________.

Many students assume that old social media posts disappear once enough time has passed. (A) A few years later, however, a teacher reviewing her application happened to notice an old, unkind comment she had posted and forgotten. (B) Minji, for instance, once left a careless comment mocking a classmate, assuming no one would ever see it again. (C) This experience taught her that a digital footprint, the lasting trail left by online activity, can resurface at unexpected moments.

Loyalty programs have become a standard feature of modern retail strategy. (A) Critics counter that such programs often reward habit rather than genuine satisfaction with a product. (B) Supporters claim that points and rewards encourage customers to return again and again. (C) True loyalty, they argue, should be built through consistent quality rather than artificial incentives.

Mina's career path illustrates how unpredictable the job market can be for graduates entering emerging fields. (A) Soon afterward, however, a small startup building a traffic-prediction app offered her a chance to analyze large sets of data. (B) At first, she struggled to find a position that matched her academic background, since few employers understood the value of her statistical skills. (C) That opportunity transformed her career, leading her eventually to lead a team of analysts mentoring the next generation.

In short, an effective fueling plan treats carbohydrate loading as one tool among many, not a substitute for well-rounded nutrition. In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice known as carbohydrate loading. ( ① ) The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins. ( ② ) Because glycogen serves as the primary fuel source during prolonged, intense exercise, entering an event with fuller stores can delay the point of exhaustion that runners often call hitting the wall. ( ③ ) Sports nutritionists caution, however, that the timing and composition of meals matter as much as the total quantity of carbohydrate consumed, since eating unfamiliar foods immediately before competition can cause digestive discomfort. Athletes are therefore advised to practice their nutrition strategy during training rather than experimenting with it for the first time on race day. ( ④ ) Beyond carbohydrates, adequate protein and micronutrient intake throughout the training cycle remains essential, since fueling strategy is only one part of a much larger nutritional picture. ( ⑤ )

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.

주어진 문장: Because the videos looked completely unscripted, audiences trusted them in a way that polished commercials rarely achieve. When a beverage company launched a new flavor last summer, the marketing team faced a tight budget and needed a creative solution. ( ① ) 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. ( ② ) Within days, thousands of people began recreating the dance and tagging the brand, turning an ordinary product launch into a viral trend. ( ③ ) Because participants created the content themselves, viewers found the videos far more entertaining than a traditional advertisement would have been. ( ④ ) The company barely spent any money on production, yet the challenge reached millions of viewers across multiple platforms. ( ⑤ ) Encouraged by this success, other brands quickly attempted similar challenges, though many failed to generate the same excitement.
