On a summer evening, downtown streets often ①feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. This phenomenon, known as the urban heat island effect, occurs when cities retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly ②radiates it back at night, preventing temperatures from cooling. Tall buildings ③packed closely together also block wind, trapping warm air within narrow streets. In contrast, areas with abundant trees and open water naturally ④stay cooler, since plants release moisture that helps lower surrounding temperatures. To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, ⑤hoping that additional greenery will absorb less heat than pavement does.

On the first day of winter break, my friend Yuna and I sat in a cafe and talked about the new year ahead. Instead of making separate plans, we decided to write our goals ①together on one sheet of paper. At first, it felt ②exciting, but after two weeks, I began to feel tired and wanted to quit. Yuna noticed my short replies and ③ignored me instead of just texting. She reminded me why I had chosen this goal in the first place, and her words gave me new ④energy. Because we supported each other through difficult moments, both of us successfully ⑤reached our goals by spring.

Every time a smartphone connects to a cell tower or a Wi-Fi network, it ①quietly records a data point that can later be pieced together into a detailed map of where its owner has been. Most users agree to this tracking without reading the fine print, assuming that a single company's database poses ②little threat. The real danger, however, emerges when location data from multiple sources is combined. A pattern that reveals a person's home, workplace, and daily route can ③expose far more than any single app ever intended to share. Companies often argue that anonymized data cannot be traced back to individuals, yet researchers have ④repeatedly shown that a handful of location points is enough to identify a specific person with striking accuracy. As a result, privacy experts increasingly insist that location data deserves ⑤minimal legal protection, similar to that of medical records.

Among the many tools available to those who design choice environments, few are as quietly powerful as the default option, the alternative that takes effect automatically unless a person actively selects something else. Because changing a default requires deliberate effort, many individuals simply accept whatever arrangement has been preselected for them. Designers of public policy and digital platforms alike have consequently come to recognize that setting a thoughtful default can achieve outcomes that ___________ often struggle to accomplish through persuasion or financial incentive alone.

Every day, we leave behind marks of the gases that warm our planet, much like footprints left in wet sand. These marks, often called our carbon footprint, _______________. Many students think that only large factories create these marks, but ordinary habits at home also matter greatly. For example, turning off lights when leaving a room reduces the energy that power plants must produce. Walking or biking to school instead of riding in a car also lowers the amount of gas released into the air. In contrast, leaving devices plugged in all night quietly increases our footprint without our notice. Therefore, students who practice these simple habits regularly can shrink their footprint significantly. Small daily choices, repeated over time, become powerful tools for protecting the environment we all share.

Introducing cobots into a factory requires careful planning to ensure both safety and productivity. (A) Once installed, however, cobots must be closely monitored, since their sensors can occasionally malfunction in noisy or crowded environments. (B) Engineers must first program the robots to recognize the exact boundaries of each worker's movement space. (C) After this initial setup, cobots can be integrated gradually, starting with simple tasks before taking on more complex ones.

Sensors buried in the soil now report moisture levels in real time, and automated systems adjust irrigation without a farmer ever walking the rows. (A) Smaller family farms, however, often cannot afford the upfront cost of this equipment, and some worry that the gap between high-tech and traditional operations will only widen. (B) For large operations with the capital to invest, these tools have measurably increased yields while reducing water waste. (C) There is also a quieter cultural cost: generations of farming knowledge risk being replaced by dashboards and automated alerts that few young farmers are taught to question.

Factories that once employed hundreds of workers on an assembly line now run with a fraction of that staff, as robotic arms handle tasks that used to require human hands. (A) However, critics point out that earlier transitions unfolded over generations, giving workers time to retrain, whereas today's robots are being deployed much faster. (B) Historical evidence offers some comfort: previous waves of automation eventually created new categories of work that no one had predicted. (C) A factory worker displaced this year, therefore, cannot simply wait for a new industry to emerge decades from now.

This makes it one of the most difficult winter hazards to prepare for in advance. When temperatures drop below freezing overnight, an invisible layer of black ice can form on sidewalks that look perfectly dry, catching even careful walkers off guard. ( ① ) Unlike a visibly icy patch, black ice reflects almost no light and blends into ordinary pavement, which is why so many falls happen on stretches that pedestrians would never suspect. ( ② ) Orthopedic doctors report a sharp rise in wrist and hip injuries every winter, most of them caused not by dramatic slips on icy hills but by a single unexpected step near a bus stop or a doorway. ( ③ ) Walking with shorter, flatter steps and keeping the hands free rather than in pockets can help a person regain balance quickly if a foot suddenly slides. ( ④ ) Choosing shoes with textured rubber soles rather than smooth ones also makes a difference, since even a small increase in grip can prevent a fall before it begins. ( ⑤ ) Treating every winter sidewalk as potentially icy, rather than trusting appearances, remains the simplest way to avoid injury.

The software company, in turn, may argue that no algorithm can be expected to be perfect. Hospitals are increasingly adopting artificial intelligence tools that can scan medical images and flag potential tumors faster than experienced radiologists. ( ① ) When an AI system misses a diagnosis that a human doctor would likely have caught, responsibility becomes difficult to assign. ( ② ) The doctor may argue that they simply trusted a tool the hospital required them to use. ( ③ ) The hospital, meanwhile, may argue that the software company guaranteed its accuracy. ( ④ ) Until legal systems clarify this chain of responsibility, patients harmed by an algorithmic error may find themselves with no clear party to hold accountable. ( ⑤ )
