A documentary director named Mira first traveled to a remote Arctic glacier to film its towering cliffs of blue ice, ①<u>which seemed frozen in time</u>. ②<u>Standing before the massive wall</u>, she assumed such an enormous structure could hardly ③<u>changed</u> within a lifetime. Five years later, however, she returned to the very same coordinates, ④<u>expecting her camera to capture</u> an identical scene. Instead, she discovered that the glacier had retreated so dramatically that the ice cliffs, once visible from her original position, had nearly disappeared, leaving bare rock and pools of meltwater behind. ⑤<u>Comparing the two sets of footage side by side</u>, Mira realized that a transformation she had expected to take centuries was actually happening within a single decade. This encounter convinced her that climate change, which she had previously regarded as a distant statistic, was in fact an urgent process reshaping landscapes before her eyes.

As millions of people now earn income through delivery apps and ride-hailing platforms, questions about their legal status ①have become increasingly urgent. Most platform workers are classified as independent contractors rather than employees, ②which means they are not entitled to minimum wage guarantees or paid sick leave. Companies favor this arrangement because it allows them ③to avoid the costs associated with hiring full employees. Worker advocates, however, argue that many platform workers ④depend on these jobs as their primary source of income. Several countries have recently begun reconsidering their labor laws, ⑤proposed new categories that would grant workers some protections.

Elite athletes often perform in front of enormous crowds with championships, contracts, and years of training riding on a single moment, and the psychological weight of that pressure can ① undermine skills that feel automatic in practice. Sports psychologists explain that intense anxiety narrows attention and disrupts the smooth, unconscious execution of well-learned movements, a phenomenon sometimes ② called choking under pressure. Rather than trying to eliminate nervousness entirely, which research suggests ③ are nearly impossible, many trainers now teach athletes ④ to reinterpret the physical symptoms of anxiety, such as a racing heart, as signs of readiness rather than danger. Over time, repeated exposure to high-pressure situations in practice, deliberately ⑤ simulated to resemble real competition, allows athletes to build tolerance the same way their muscles adapt to physical training.

Until last spring, Minji ①**rarely** thought twice about tossing a paper cup into the trash after finishing her coffee. Environmental issues seemed ②**distant**, something scientists and politicians should handle rather than an ordinary student like her. That changed when her class was assigned a documentary about plastic waste drifting through the ocean, footage she initially expected to find boring. Instead, watching seabirds mistake plastic fragments for food left her strangely ③**comforted**, and she found herself thinking about the assignment long after class ended. The next morning, almost without deciding to, she slipped her old tumbler into her backpack instead of buying a disposable cup on the way to school. It felt like a small, ④**meaningless** gesture at first. However, as weeks passed, she realized that consistently choosing the tumbler, declining a plastic straw, and reusing a shopping bag were quietly ⑤**adding up**. Small choices, she discovered, become meaningful once repeated.

As governments and companies work to address climate change, a new category of employment known as green jobs has ①expanded rapidly. Unlike many traditional industrial jobs, green jobs often require workers to combine technical training with an understanding of environmental science. Countries that have invested heavily in renewable energy have seen employment in this sector grow far ②faster than in the economy overall. Young workers, in particular, are drawn to green careers because they offer a sense of purpose alongside financial ③stability. Critics point out that transitioning workers from fossil fuel industries to green jobs can be surprisingly ④easy, since the required skills can differ significantly. Governments are therefore introducing training programs designed to help such workers shift ⑤smoothly into renewable energy careers.

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. Part of the problem lies in biology: as puberty begins, the body's internal clock naturally ① shifts later, making it difficult for teenagers to fall asleep before eleven at night. Yet school start times rarely adjust to this shift, forcing students to wake before their bodies are ready. The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to ② impaired concentration, weakened memory, and a higher risk of anxiety and depression. It can also disrupt the hormones that regulate appetite, contributing to ③ 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 ④ worsened grades, better mood, and fewer tardy arrivals. Despite this evidence, changing entrenched school schedules remains a slow and ⑤ contentious process.

As more businesses move their operations online, cyberattacks have become one of the most serious threats facing modern companies. In response, demand for cybersecurity professionals has surged across nearly every industry. Despite this expansion, experts estimate that ___________, largely because the number of qualified applicants has not kept pace with rapidly increasing demand. This shortage suggests that cybersecurity will remain a promising career path for years to come.

The pace of technological change has forced professionals to rethink how they approach their careers. (A) As a result, many now treat learning as an ongoing part of their careers rather than something that ends at graduation. (B) A skill considered valuable just five years ago may already be outdated today, forcing workers to update their knowledge constantly. (C) Naturally, some professionals find this constant demand for new skills stressful and difficult to manage alongside other responsibilities.

This mismatch between internal time and local time is the true source of the problem, not the flight itself. Travelers who cross several time zones in a single flight often arrive feeling exhausted, foggy, and strangely out of sync with the local clock, a condition widely known as jet lag. ( ① ) The discomfort arises because the body's internal clock, which governs sleep, hunger, and alertness, continues to run on the schedule of the departure city even after landing. ( ② ) Realigning this internal clock to a new time zone is not instantaneous; researchers estimate that the body typically needs about one day to adjust for every time zone crossed. ( ③ ) Flying eastward tends to produce more severe symptoms than flying westward, because advancing the internal clock forward is generally harder for the body than delaying it. ( ④ ) Exposure to natural light at the right moments after arrival can help speed up the adjustment, since light is the strongest external cue the internal clock uses to reset itself. ( ⑤ ) Without such adjustments, travelers may continue to experience disrupted sleep and reduced concentration for several days after a long international flight.

This constant, individualized adjustment is what makes the technology feel so different from a standard workbook. Adaptive learning apps promise something no traditional classroom can easily offer: a lesson plan that adjusts itself to each individual student in real time. ( ① ) As a student answers practice questions, the app tracks which concepts are mastered and which remain shaky, then quietly reshuffles the next set of problems to target the weaker areas. ( ② ) Early studies suggest that this personalized pacing can help struggling students catch up faster than a one-size-fits-all worksheet ever could. ( ③ ) However, critics caution that an app cannot replace the encouragement, humor, and flexibility a human teacher brings to a lesson, especially when a student is frustrated rather than simply behind. ( ④ ) There is also a subtler concern: students who grow used to instant, algorithm-generated feedback may struggle later with the slower, more ambiguous kind of feedback that real-world tasks and mentors typically provide. ( ⑤ )
