Three-dimensional printing technology is changing how products are designed and manufactured across many industries. Unlike traditional manufacturing, ①which often requires expensive molds and long production times, 3D printers can create complex objects directly from digital files within hours. This flexibility allows companies ②to produce small batches of customized products without the massive costs typically associated with mass production. Hospitals now use 3D printing to create prosthetic limbs ③tailored precisely to individual patients, while automakers use it to build lightweight parts that reduce vehicle weight. Small businesses, too, have benefited enormously, since the technology ④lower the barrier to entry for entrepreneurs. As printing materials improve and machines become faster, the technology is expected ⑤to play an increasingly central role in future manufacturing.

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.

Team sports place athletes in a uniquely social form of competition, one where individual skill alone ①rarely determines the outcome of a match. Sports psychologists have long studied why some groups of talented individual players fail to perform as a cohesive unit while other, less individually skilled teams consistently ②exceed expectations. Trust among teammates appears to be a ③decisive factor, since players who believe their teammates will reliably fulfill their roles are more willing to take the calculated risks that winning often requires. Clear and consistent communication during high-pressure moments further reduces the hesitation and confusion that can ④unravel a team's coordination in front of a crowd. Interestingly, researchers have found that teams which deliberately build informal social bonds off the field tend to display better on-field cohesion, suggesting that chemistry can ⑤easily be manufactured through drills alone.

For decades, athletes were taught to stretch a muscle and hold the position before any competition, believing that this practice alone would ①prevent injury. Recent research, however, has complicated that assumption considerably. Static stretching, in which a muscle is held at its longest length for an extended period, can actually ②reduce the muscle's ability to generate explosive force immediately afterward, which is troubling for sprinters or jumpers who need maximum power right away. Dynamic stretching, which involves controlled, repeated movement through a joint's full range of motion, appears to ③prepare muscles for activity without this temporary weakening effect. As a result, many coaches now recommend ④saving static stretching for after a workout, when it may help restore muscle length and reduce soreness, while reserving dynamic movements for the warm-up period before intense effort begins. The right technique, in other words, depends heavily on ⑤chance.

Imagine a cafeteria where a healthy salad sits at eye level while fried snacks rest on a low shelf. Nobody is forbidden from choosing the snacks, yet most people quietly pick the salad instead. This simple technique illustrates a nudge, a concept from behavioral economics _______________. Companies and governments increasingly apply nudges to encourage sustainable consumption. For example, some hotels print reminders on towels stating that most guests reuse them, which persuades new guests to do the same and save water. Similarly, energy bills that compare a household's usage with that of efficient neighbors often lead people to reduce electricity use. Unlike strict regulations or heavy taxes, nudges rely on subtle changes in design rather than force. Critics argue nudges alone cannot solve large environmental problems, but combined with stronger policies, they can meaningfully shift everyday habits toward sustainability.

Athletes preparing for major endurance events sometimes train for weeks at high altitude, where the air contains less oxygen than at sea level. In this thin air, the body responds by producing more red blood cells, which carry oxygen more efficiently through the bloodstream to working muscles. When these athletes return to sea level, their blood retains this elevated capacity for a limited period, potentially translating into improved endurance performance. However, the benefits of altitude training are far from guaranteed, since individual athletes respond quite differently to the same conditions, and some experience excessive fatigue that undermines the very training they hoped to complete. Many elite programs therefore follow a strategy known as live high, train low, in which _______________.

Understanding the perfectionism-procrastination cycle can help students break free from a frustrating pattern of delay. (A) This fear does not mean perfectionists lack motivation; rather, it pushes them to delay the task in order to avoid confronting their own high standards. (B) As a result, many perfectionists end up completing work at the last possible moment, which paradoxically increases the likelihood of the very mistakes they feared. (C) When someone holds unrealistic expectations for a task, the fear of falling short often becomes so intense that starting the task itself feels dangerous.

주어진 문장: She had rehearsed exactly what she would say the moment their eyes finally met. Minji spent nearly every evening watching Jimin, an online creator who streamed cooking videos and chatted casually with her viewers. ( ① ) Over several months, Minji began to feel as though she truly knew Jimin, laughing at her jokes and worrying whenever she mentioned having a difficult week. ( ② ) Whenever Jimin responded to a comment, even a simple one, Minji felt a small thrill of connection, as if they were becoming closer friends. ( ③ ) One day, Minji excitedly waited outside a fan event, hoping that Jimin would recognize her from the countless messages she had sent. ( ④ ) However, Jimin greeted her the same way she greeted every other stranger in line, without any hint of personal recognition. ( ⑤ ) Standing there, Minji slowly realized that the bond she had imagined was entirely one-sided, existing only in her own mind. This type of connection, known as a parasocial relationship, can feel remarkably real despite never being mutual.

That two- or three-hour gap may look modest on paper, but its effects accumulate quickly, touching everything from mood to memory. Across the world, teenagers are chronically short on sleep, often getting two or three hours less than the eight to ten hours experts recommend for their age. ( ① ) Part of the problem lies in biology: as puberty begins, the body's internal clock naturally shifts later, making it difficult for teenagers to fall asleep before eleven at night. ( ② ) Yet school start times rarely adjust to this shift, forcing students to wake before their bodies are ready. ( ③ ) The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to impaired concentration, weakened memory, and a higher risk of anxiety and depression. ( ④ ) It can also disrupt the hormones that regulate appetite, contributing to unhealthy weight gain over time. Some school districts have experimented with delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show improved grades, better mood, and fewer tardy arrivals. ( ⑤ ) Despite this evidence, changing entrenched school schedules remains a slow and contentious process.

주어진 문장: Researchers have found that people who use this method are significantly more likely to follow through on their goals than those who rely on willpower alone. Last January, Minji wrote the same resolution she always wrote: study English for an hour every day. ( ① ) By February, she had already quit, just as in previous years. Frustrated, she asked her teacher why her willpower always failed, and learned about a concept called implementation intentions. ( ② ) This idea, developed by psychologists, means forming a specific if-then plan that links a certain situation to a certain action in advance. ( ③ ) Instead of vaguely intending to study more, Minji made a precise plan: if she finished dinner, then she would study for thirty minutes. ( ④ ) She also prepared a backup plan: if she felt too tired, then she would study for just ten minutes instead of skipping entirely. ( ⑤ ) Because these plans removed the need to decide anything in the moment, starting became far easier for Minji. By December, she had studied for eleven straight months, proving that clear if-then plans beat vague intentions.
