When Mina graduated from college five years ago, she had never even heard the term "data scientist." After graduation, she ①struggled to find a job that matched her interests, since most companies did not fully understand what her skills were worth. Everything changed when a small tech startup hired her to ②analyze massive amounts of data. Mina quickly discovered that she loved turning raw numbers into insights that helped real people make ③worse decisions. Within two years, demand for professionals like her had ④exploded, as companies in every industry realized how valuable data could be. Today, Mina ⑤leads a team of ten analysts, mentoring young graduates.

A flexitarian is someone who mainly eats plant-based meals but occasionally includes meat or fish, unlike a ①strict vegetarian who avoids animal products entirely. This flexible diet has recently ②lost attention as a practical way to fight climate change, since raising livestock produces a ③significant portion of global greenhouse gas emissions. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere. By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can ④noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a ⑤realistic first step, believing that gradual change, rather than sudden restriction, is more likely to spread widely across society.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and _______________. Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.

Not all relationships that people form are equally close or meaningful. (A) Robin Dunbar, an anthropologist, argued that the human brain can only support about one hundred fifty stable relationships at once. (B) Consequently, most of the hundreds of online followers a person accumulates never become genuinely close acquaintances. (C) This cognitive limit applies regardless of how many friends or followers a person collects on social media.

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. (A) These small conveniences 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. (B) Over months of use, the system becomes noticeably better at anticipating needs, often adjusting settings moments before a resident would have reached for a switch. (C) Yet convenience comes with a trade-off that many households overlook, since a detailed record of daily habits is quietly being stored somewhere beyond their immediate control.

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.

주어진 문장: Because the timer makes each interval visible and concrete, students often feel a stronger sense of urgency during each session. Among strategies for improving concentration, the Pomodoro Technique remains one of the most widely recommended methods for students and workers. ( ① ) This technique involves working with full attention for twenty-five minutes, then taking a short five-minute break before starting the next session. ( ② ) After completing four of these cycles, a longer break of fifteen to thirty minutes is usually taken to allow mental recovery. ( ③ ) The method assumes that sustained focus becomes harder to maintain as time passes, so frequent short breaks prevent mental fatigue from building up. ( ④ ) Students preparing for exams report finishing reading assignments faster when they follow this structured rhythm instead of studying without interruption. Office workers find that dividing large projects into short, timed intervals makes overwhelming tasks feel more manageable. ( ⑤ ) Because each interval has a clear start and end, procrastination becomes less tempting, since beginning a single twenty-five-minute session requires less commitment than beginning an entire project.

주어진 문장: At first, this seemed like a small, sentimental gesture with little business value. Years ago, a small shoe company struggled to compete with larger, well-funded rivals in the market. ( ① ) Its products were solid, but customers rarely remembered the brand after a single purchase. One day, the founder decided to share the story behind the company: how her grandfather had once repaired shoes for factory workers who could not afford new pairs. She began printing this story on every shoebox and posting it across social media. ( ② ) Surprisingly, customers started responding not just to the shoes themselves but to the values the story represented. ( ③ ) Sales slowly increased as people felt they were supporting something meaningful rather than simply buying a product. ( ④ ) Other companies noticed this shift and began crafting their own narratives, hoping to create similar emotional connections. ( ⑤ ) Eventually, the founder realized that a compelling story, told honestly, could turn ordinary customers into loyal supporters.

주어진 문장: This is why many coaches encourage athletes to keep their pre-game rituals exactly the same, even when circumstances change. Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. ( ① ) This theory explains that every habit begins with a cue, a signal that tells the brain to start an automatic behavior. ( ② ) The brain then performs a routine, which is the action itself, whether physical or mental. ( ③ ) Finally, the brain receives a reward, a positive feeling that makes it want to repeat the same behavior. ( ④ ) For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run without conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. ( ⑤ ) Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

주어진 문장: Creating a convincing avatar, in other words, is far more complex than simply choosing a picture. The metaverse, a network of interconnected virtual worlds, has begun to generate job opportunities that did not exist just a few years ago. ( ① ) Companies now hire virtual world designers who build digital environments where users can socialize, shop, or attend events. Avatar designers create digital identities that represent users within these spaces, blending artistic skill with technical programming knowledge. ( ② ) Meanwhile, virtual event planners organize concerts, conferences, and product launches entirely within online platforms, reaching audiences that would be impossible to gather in person. ( ③ ) Some analysts remain skeptical, pointing out that the metaverse has not yet attracted the massive user base that early predictions promised. ( ④ ) Nevertheless, major companies continue investing heavily in this technology. ( ⑤ ) For students considering future careers, gaining skills in three-dimensional design and coding may prove valuable.
