Modern factories increasingly rely on collaborative robots, often called cobots, ①which are designed to work safely alongside human employees. Unlike traditional industrial robots that operate behind safety cages, cobots use sensors ②detect nearby workers and adjust their movements accordingly. In practice, cobots typically handle repetitive or physically demanding tasks, such as ③lifting heavy parts, while human workers focus on tasks that require judgment. This division of labor increases overall efficiency, since each side ④contributes what it does best. Manufacturers who have introduced cobots report fewer workplace injuries, largely because employees no longer ⑤perform exhausting repetitive motions all day.

Across many countries, high schools begin classes ① early in the morning, often before eight o'clock. This schedule assumes that teenagers can simply go to bed earlier to compensate, but biology tells a different story. During adolescence, the body's internal clock shifts ② earlier, delaying the release of melatonin until well after ten at night. As a result, most teenagers are not physiologically ready to fall asleep until much later than younger children or adults. When early start times force them to wake before their bodies have completed a full sleep cycle, the mismatch ③ accumulates into a chronic sleep debt that affects concentration and mood throughout the school day. Researchers who study this mismatch argue that the underlying problem is not laziness or poor discipline among students, but a scheduling system built around adult rhythms rather than ④ adolescent ones. Some school districts that delayed their start times by thirty minutes reported ⑤ measurable improvements in attendance.

Self-driving technology is advancing rapidly, and its impact on the transportation industry is becoming increasingly ①visible. Companies are testing autonomous trucks that can travel long distances without human drivers, potentially ②transforming how goods move across countries. Millions of professional drivers worry about losing their jobs as automation ③spreads through the industry. Experts predict that certain driving jobs, particularly long-distance trucking, may shrink significantly within the next two decades. However, new roles are also ④emerging, including remote vehicle operators who monitor fleets of autonomous trucks. Workers who adapt their skills toward supervising and maintaining these systems are likely to find new opportunities rather than face ⑤employment.

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. The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins. Because glycogen serves as the primary fuel source during prolonged, intense exercise, _______________. 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.

A navigation app calculating a route rarely relies on distance alone; instead, it constantly weighs real-time traffic reports, past congestion patterns, and even data from other drivers' phones currently on the road. This flood of information allows the app to reroute a driver away from a sudden accident within seconds. The convenience comes at a cost that few passengers consider, however. When thousands of drivers are simultaneously redirected onto the same shortcut, _______________, arguing that an algorithm optimizing for individual convenience can end up creating a new, entirely different problem for the wider community.

Scientists have identified certain gene variants that appear more frequently among elite endurance athletes than among the general population, along with a separate set that seems to favor explosive, power-based sports such as sprinting. (A) However, researchers caution strongly against interpreting these findings as evidence that athletic greatness is simply inherited. (B) One frequently studied variant, for instance, influences the proportion of slow-twitch versus fast-twitch muscle fibers a person naturally develops, a ratio that shapes whether a body leans toward endurance or explosive power. (C) Genetics may set a rough ceiling on an individual's ultimate potential, but where any particular athlete lands within that range depends overwhelmingly on training quality, nutrition, coaching, and sheer determination.

The growing sophistication of cyberattacks has transformed cybersecurity into one of the most in-demand career fields. (A) Universities have responded to this trend by launching specialized degree programs focused entirely on cybersecurity. (B) As a result, businesses across nearly every industry now compete to hire qualified security professionals. (C) Hackers today target organizations of every size, from small retailers to major financial institutions.

주어진 문장: This misconception, sometimes called the twenty-one-day myth, has been repeated so often that many people accept it without question. Many people believe that a new habit becomes automatic after only twenty-one days, but researchers who examined real behavior found a different number. ( ① ) This project, called the 66-day habit formation study, tracked volunteers who tried to adopt a new daily habit, like drinking water with lunch. ( ② ) Researchers measured how automatic each action felt over time and found that habits needed an average of sixty-six days to become effortless. ( ③ ) Yet the actual time varied widely, ranging from about eighteen days for simple habits to over two hundred days for difficult ones. ( ④ ) This wide range explains why the popular twenty-one-day claim, though easy to remember, rarely matches real experience. ( ⑤ ) For instance, flossing might feel automatic within a few weeks, while jogging every morning may take months to feel natural. The study's central lesson is that patience matters more than speed when building lasting habits.

주어진 문장: This unexpected combination of skills fascinated him more than he had expected. When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers belonged only to a handful of government scientists. ( ① ) By the time he entered university, however, the space industry had changed dramatically, as private companies began launching satellites and building reusable rockets. ( ② ) Daniel studied aerospace engineering, drawn to the idea that space exploration was no longer limited to a few national agencies. ( ③ ) During an internship, he helped design a small satellite intended to monitor crop health from orbit, a project that combined engineering with agricultural science. ( ④ ) He realized that the space industry now needed not only pilots and engineers but also data analysts, technicians, and even lawyers familiar with international space regulations. ( ⑤ ) After graduation, Daniel joined a startup developing lunar landing equipment, a job that barely existed when he first imagined his future career.

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.
