Consider a large heap containing ten thousand grains of sand. Nearly everyone agrees that removing a single grain from such a heap ① leave another heap behind; surely one grain could never make the difference between a heap and a non-heap. Yet if this principle is applied repeatedly, grain by grain, the heap eventually shrinks to a single lonely grain, or even to no grains at all, and logic alone seems to ② force us to accept that this final result still counts as a heap. Something has clearly gone wrong along the way, since no reasonable person would ③ call one grain of sand a heap, but pinpointing exactly which single removal transformed a heap into a non-heap seems ④ impossible. The puzzle exposes a deep discomfort with vague terms like "heap," "tall," or "bald," concepts that seem to admit no sharp boundary yet are ⑤ used confidently in everyday language.

Every summer, lifeguards repeat the same warnings to swimmers, yet drowning remains one of the most common causes of accidental death among teenagers. Part of the problem is that danger in water rarely ① looks dramatic; a swimmer struggling to stay afloat often makes little noise and shows no obvious signs of panic, which means bystanders may not realize help ② needing until it is too late. Rip currents present a particularly deceptive threat, since the water's surface can appear calm even while a powerful current ③ pulls a swimmer steadily away from shore. Experts advise that anyone caught in such a current should swim parallel to the beach rather than ④ struggling directly against it, since fighting the current head-on quickly exhausts even a strong swimmer. Simple habits, such as swimming near a lifeguard station and never entering the water alone, dramatically lower the risk of a minor mistake ⑤ turning into a fatal one.

Artificial intelligence has begun to play a surprising role in creative industries once thought to be uniquely human. Some artists ①welcome this technology, using AI tools to explore new styles or overcome creative blocks that once took weeks to resolve. Others, however, argue that AI-generated art ②lacks the emotional depth that comes from genuine human experience. Despite this debate, most experts agree that AI is unlikely to fully ③replace artists anytime soon. Instead, it functions best as a collaborative tool, helping creators experiment ④faster while leaving final artistic decisions to humans. Therefore, artists who learn to work alongside AI may find themselves with a distinct ⑤disadvantage in this rapidly changing industry.

As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions have emerged about how that information should be handled. Employees who work with big data now face ①minimal responsibilities that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. Some argue that strict regulations should govern data collection, even if such rules ②slow innovation and increase costs for businesses. Others insist that self-regulation within companies, guided by clear ethical training, can protect consumers just as ③effectively without stifling progress. Most experts agree that professionals handling sensitive data must be trained not only in technical skills but also in ethical ④decision-making. Universities have begun adding data ethics courses, recognizing that future employees will need to ⑤balance innovation with responsibility.

Factories that once employed hundreds of workers on an assembly line now run with a ① fraction of that staff, as robotic arms handle tasks that used to require human hands. Economists have long debated whether this shift destroys jobs or simply transforms them. Historical evidence offers some ② comfort: previous waves of automation eventually created new categories of work that no one had predicted. However, critics point out that earlier transitions unfolded over generations, giving workers ③ ample time to retrain, whereas today's robots are being deployed at a pace that leaves little room for adjustment. A factory worker displaced this year cannot simply wait for a new industry to emerge decades from now. For this reason, many economists argue that the real ④ challenge is not the robots themselves, but the ⑤ sluggish speed at which society is expected to adapt to them.

Minji had tried for years to build a bedtime reading habit but always ①forgot once under the blanket. During summer, she found a method called habit stacking. It means attaching a new habit to an existing one so it acts as a reminder. Her existing habit was brushing her teeth every night, so she decided to place her book ②far from her toothbrush. After brushing her teeth, she would pick up the book, letting one action trigger the next. Within two weeks, opening the book after brushing felt almost ③automatic, requiring no conscious effort. She realized habit stacking worked best when the new habit was ④small and the existing habit was stable and predictable. By the end of summer, both habits felt like ⑤steady parts of her routine, requiring no reminders.

Eyewitness testimony has long carried weight in courtrooms, yet decades of research reveal that memories of witnessed events are more ①malleable than most people assume. When individuals who observe an event are later exposed to ②misleading information about what they saw, whether through a leading question or a conversation with another witness, their recollections frequently incorporate details that never occurred, a phenomenon known as the misinformation effect. In one classic paradigm, participants who watched a video of a traffic accident and were then asked how fast the cars were going when they smashed into each other reported ③higher speed estimates and were more likely to falsely recall broken glass than participants asked the identical question using the milder verb hit. Crucially, these distorted memories often feel ④genuine to the person experiencing them, since the original memory trace becomes blended with the newly introduced information rather than existing as a separate, contradictory record. Such findings have prompted legal systems to adopt ⑤careless interviewing protocols designed to minimize suggestive questioning during investigations.

As more schools shift toward digital textbooks and online assignments, a student without reliable internet access at home faces a disadvantage that has little to do with talent or effort. (A) That assumption is increasingly being reconsidered, particularly as more essential services, from job applications to medical appointments, move online by default. (B) Some policymakers initially treated internet access as a convenience, comparable to cable television, rather than as infrastructure essential to modern life. (C) Closing this divide will require more than simply distributing devices; it will demand sustained investment in the physical networks that carry information into every home.

Not long ago, Junho felt he needed to check his phone every few minutes just to keep up with his friends. (A) During this unplanned break from his phone, he was surprised to discover that he actually felt calmer rather than anxious. (B) Encouraged by this experience, he began setting aside phone-free hours on purpose, gradually growing comfortable with being offline. (C) This constant checking left him drained, until one day his phone battery died unexpectedly during a trip.

**주어진 문장**: As a result, the combined effect of heat-absorbing surfaces and limited greenery can raise nighttime temperatures in cities by several additional degrees. 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. ① 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. ② Furthermore, the scarcity of vegetation in densely built areas removes a natural cooling mechanism, since plants lower temperatures by evaporating water from their leaves. ③ To address this problem, urban planners have begun implementing mitigation strategies designed to lower surface and air temperatures. ④ One widely used solution involves reflective "cool" roofing engineered to reflect more sunlight than dark rooftops absorb. Another strategy, green infrastructure, incorporates rooftop gardens and tree-lined streets that provide shade while releasing moisture. ⑤ In contrast, some cities have pursued permeable pavements that let water seep through and evaporate, cooling nearby surfaces. ① ② ③ ④ ⑤
