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.

Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that ①governs when we feel alert and when we feel drowsy. This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. When morning sunlight strikes the retina, the cluster signals the body to ②suppress sleep hormones and raise body temperature, preparing us for activity. As evening approaches and light fades, the same mechanism triggers the release of melatonin, a hormone that ③promotes drowsiness. Because this rhythm evolved around the natural cycle of day and night, modern habits such as staying indoors under artificial light or working night shifts can push the internal clock ④out of sync with the external environment. Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and ⑤heightened concentration, suggesting that timing matters as much as total sleep hours.

Time blocking is a time-management technique in which a person divides the day into fixed blocks. Each block is then assigned to a single task. Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. This approach ①lowers the mental effort of deciding what to do next, since the schedule already provides the answer. It also ②limits multitasking, because each block is reserved for only one activity at a time. For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing. Because each block has a ③vague boundary, unfinished work is ④less likely to quietly spread into the next task. Many people who adopt time blocking feel ⑤more organized throughout the day.

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.

Jiho had always assumed he would join a large corporation after graduation, just as his parents expected. During his final year of university, however, he joined a small student team building an app that connected local farmers directly with restaurants. After nearly failing twice, the team secured a small investment that allowed them to hire their first employee. Looking back, Jiho believes that ___________.

The rise of autonomous vehicles has created both excitement and anxiety within the transportation industry. (A) In particular, long-distance trucking jobs are expected to shrink significantly as autonomous trucks become more common on highways. (B) At the same time, entirely new positions are emerging, such as remote operators who monitor fleets of self-driving vehicles from control centers. (C) On one hand, many professional drivers fear that automation will eliminate the jobs they currently depend on.

Many economists have studied how automation affects different sectors of the economy, and their research reveals a consistent pattern. (A) For example, manufacturing plants that adopted robotics saw production speed double within five years, while the number of routine assembly jobs fell sharply. (B) As a result, workers today are encouraged to develop skills that complement machines rather than compete with them, such as creativity and critical thinking. (C) At first, automation mainly affected repetitive manual tasks in manufacturing, but it has since spread into administrative and even creative fields.

The classification of platform workers has become one of the most debated issues in modern labor law. (A) For this reason, companies generally prefer classifying these workers as independent contractors rather than full employees. (B) Being classified this way, however, means workers miss out on protections such as minimum wage and paid leave. (C) Employee status requires companies to provide benefits and follow strict labor regulations, which increases operating costs.

주어진 문장: In fields ranging from medicine to law, these tools now perform tasks that once required years of human training. As artificial intelligence grows more capable of performing tasks once considered exclusively human, many people wonder which skills will remain valuable in the future. ( ① ) AI can now analyze data, generate text, and even diagnose certain medical conditions with impressive accuracy. ( ② ) However, most researchers argue that AI still struggles with tasks requiring genuine empathy, ethical judgment, and creative problem-solving in unfamiliar situations. ( ③ ) A machine can recommend a treatment plan based on statistics, for instance, but it cannot comfort a frightened patient the way a compassionate nurse can. ( ④ ) Similarly, AI can generate countless design variations, yet it lacks the lived experience that allows humans to judge which idea truly resonates with people. ( ⑤ ) For this reason, educators increasingly emphasize skills such as collaboration, critical thinking, and emotional intelligence.

주어진 문장: This flexibility, however, comes with a hidden cost that many workers overlook. Remote work has moved from a rare privilege to a common practice for millions of employees worldwide. ( ① ) Many companies that once required workers to commute daily now allow them to complete tasks from home. ( ② ) Supporters argue that remote work increases productivity, since employees avoid long commutes and distracting office environments. ( ③ ) It also allows companies to hire talented people regardless of where they live, widening the pool of candidates. ( ④ ) Critics, however, worry that remote work weakens teamwork and makes it harder for new employees to learn from experienced colleagues. ( ⑤ ) Without regular face-to-face interaction, some workers feel isolated and struggle to build strong professional relationships.
