Physical education class often feels like the one period of the day when students can finally move freely, which sometimes leads them ①to skip the warm-up routine that teachers insist on before any real activity begins. Cold muscles, however, are noticeably ②less flexible than warmed ones, and stretching a stiff hamstring or ankle too quickly can cause a strain that keeps a student off the field for weeks rather than minutes. Coaches often compare an unwarmed muscle to a cold rubber band that ③snap rather than stretches under sudden pressure. Beyond warming up, wearing proper footwear matters more than most students realize; running in worn-out sneakers with little grip left on the sole significantly ④raises the chance of a twisted ankle on a gym floor or an outdoor field. Reporting a minor pain immediately, rather than pushing through it to finish a game, also ⑤prevents a small issue from becoming a repeated injury that lingers for an entire season.

After a viewer finishes an episode, a streaming service rarely ①leave the choice of what to watch next entirely up to chance. Instead, a recommendation algorithm compares that viewer's habits with patterns ②drawn from millions of other users who watched similar content, then ranks thousands of titles in order of predicted interest. This approach keeps viewers engaged far longer than a simple list of new releases ever could, which is precisely why streaming companies invest so heavily in ③refining it. The system is not without drawbacks, however. Because the algorithm favors titles similar to what a viewer already enjoys, it can quietly narrow someone's exposure to unfamiliar genres, directors, or cultures, ④creating a comfortable but repetitive bubble. Some platforms have begun inserting occasional wildcard suggestions, deliberately unrelated to past viewing habits, in an attempt ⑤to counteract this narrowing effect.

Internet activist Eli Pariser introduced the term filter bubble to describe a phenomenon created by online algorithms. Social media platforms and search engines constantly track which links users click and how long they linger on certain posts. Based on this data, algorithms predict what each individual is most likely to enjoy and quietly prioritize similar content in future results. As a result, two people who type the same search query can receive strikingly different results, each tailored to personal history. This automatic filtering happens silently, without users ever deciding to limit what they see. Consequently, many people gradually lose access to viewpoints that challenge their existing beliefs, even though they never intended to avoid them. Pariser warned that this invisible curation could weaken democratic debate by narrowing public discussion. Therefore, some experts argue that platforms should reveal how content is filtered, _______________.

Adaptive learning apps promise something no traditional classroom can easily offer: a lesson plan that adjusts itself to each individual student in real time. 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. However, critics caution that _______________. 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.

As cities have expanded across landscapes once covered with absorbent soil, impervious surfaces have turned stormwater from a resource that recharges groundwater into a hazard that floods streets and carries pollutants into waterways. Green infrastructure, which mimics the hydrological functions that natural landscapes once performed, offers planners _______________. Rain gardens, shallow depressions planted with deep-rooted vegetation, are designed to capture runoff from rooftops, allowing it to filter slowly through soil before reaching underground aquifers. Permeable pavement, made of porous materials that let water pass directly through, serves a similar purpose along sidewalks, where asphalt would remain impenetrable. For example, cities that replaced pavement with permeable alternatives have reported notable reductions in flooding during storms that once overwhelmed sewers. However, engineers caution that green infrastructure cannot entirely replace conventional pipes in dense cores, where heavy runoff still requires structural reinforcement. Consequently, municipalities now regard green and gray infrastructure as complementary systems, each compensating for the other's limitations.

The ecological footprint, a widely cited measure of how much biologically productive land and water a population requires to sustain its consumption, has become one of the most familiar tools for communicating humanity's environmental impact. By converting diverse activities, from driving to eating meat, into a single unit of land area, the measure allows policymakers to grasp whether a lifestyle exceeds what the planet can regenerate. (A) Because the footprint aggregates dissimilar impacts, such as carbon emissions and water scarcity, into one composite figure, it can obscure important differences among problems that require distinct policy responses. A region might reduce its footprint by lowering carbon emissions while simultaneously depleting a local aquifer, yet the aggregate number could still appear to improve, concealing damage that demands urgent attention. (B) This simplicity, however, is also the source of its most persistent criticism. (C) Furthermore, the method assumes that all bio-productive land is roughly interchangeable, treating a hectare of forest as equivalent to a hectare of farmland, even though the two provide markedly different ecological functions.

Cities are frequently several degrees warmer than the surrounding countryside, a phenomenon known as the urban heat island effect, which intensifies in summer and threatens public health. (A) This disparity arises largely because asphalt and concrete absorb solar radiation during the day and slowly release it as heat throughout the night, preventing urban areas from cooling down. Furthermore, the scarcity of vegetation in densely built areas removes a natural cooling mechanism, since plants lower temperatures by evaporating water from their leaves. (B) Another strategy, green infrastructure, incorporates rooftop gardens and tree-lined streets that provide shade while releasing moisture. In contrast, some cities have pursued permeable pavements that let water seep through and evaporate, cooling nearby surfaces. Collectively, these strategies show that reducing urban heat depends on combining approaches suited to a city's geography. (C) To address this problem, urban planners have begun implementing mitigation strategies designed to lower surface and air temperatures. One widely used solution involves reflective "cool" roofing engineered to reflect more sunlight than dark rooftops absorb.

Our film club spent an entire semester making a five-minute short film, and I was startled to learn just how little of that time was actually spent filming. (A) By the time our short film premiered at the school festival, I understood that the visible five minutes represented only a small fraction of the invisible work that had shaped it. (B) We wrote and rewrote the script for nearly a month, then spent another two weeks drawing simple storyboards to plan every camera angle before a single scene was recorded. (C) Filming itself took only two Saturday afternoons, yet editing the footage afterward consumed nearly six additional weeks, as we combed through hours of raw clips to choose the handful of seconds that made it into the final version.

Not everyone in the neighborhood, however, shared that reaction. Walking through the old industrial district downtown, I noticed that a gray concrete wall had been transformed overnight into a wild swirl of color, letters, and cartoon figures. ( ① ) Some residents complained to the city office, calling it vandalism and demanding that workers paint over it immediately. ( ② ) Others argued that the same wall had been an ugly, forgotten eyesore for years, and that the graffiti artist had simply given it a voice no one else bothered to give it. ( ③ ) This disagreement reveals a tension at the heart of street art: without permission, even a skillful and thoughtful piece can be labeled a crime, yet many cities now invite graffiti artists to paint designated walls legally, hoping to channel that same creative energy into something the whole neighborhood can enjoy. ( ④ ) The line between vandalism and art, it seems, often depends less on the paint itself than on who gave permission to use the wall. ( ⑤ )

주어진 문장: Back then, few people could have predicted that such a job would even exist. When Mina graduated from college five years ago, she had never even heard the term "data scientist." ( ① ) She had studied statistics simply because she enjoyed solving puzzles with numbers. ( ② ) Everything changed when a small tech startup, which was building an app to predict traffic patterns, hired her to analyze massive amounts of data. ( ③ ) Mina quickly discovered that she loved turning raw numbers into insights that helped real people make better decisions. ( ④ ) Within two years, demand for professionals like her had exploded, as companies in every industry realized how valuable data could be. ( ⑤ ) Today, Mina leads a team of ten analysts, mentoring young graduates.
