A smart thermostat that learns a family's daily rhythm can lower the temperature automatically before everyone wakes up cold, while smart lights ①that follow a resident's schedule no longer need to be switched on and off by hand. These small conveniences rest on a shared foundation: sensors collect data about temperature, motion, and light throughout the home, and an algorithm gradually learns ②which settings match each household's actual habits rather than a factory default. Over months of use, the system becomes noticeably better at ③anticipate needs, often adjusting settings moments before a resident would have reached for a switch. Yet convenience comes with a trade-off that many households ④overlook. Every one of these small adjustments depends on constant data collection, meaning that a detailed record of when people wake, leave, and return home is quietly ⑤being stored somewhere beyond their immediate control.

Imagine watching a fair coin land on heads five times in a row and ①feeling an increasingly strong intuition that the next flip is somehow due to produce tails. This intuition, though psychologically compelling, rests on a basic misunderstanding of probability, since each flip of a fair coin ②remains entirely independent of every flip that came before it. The coin possesses no memory of its previous outcomes, and its probability of landing on tails on the sixth flip ③stays fixed at fifty percent regardless of how many heads preceded it. Casinos have long profited from this misconception, watching gamblers place larger bets after a losing streak simply because they mistakenly ④believing that a win has become statistically overdue. Economists have even documented the same error among trained professionals, including loan officers ⑤who grow more likely to approve a risky application simply because they recently rejected several applications in a row.

Every spring, our school holds an art exhibition in the main hallway, and this year I finally submitted a painting of my own. For weeks, I compared my work to my classmates' drawings and felt ①sure that mine was not good enough to hang beside theirs. My art teacher noticed my ②hesitation and said something I did not expect: an exhibition is not a contest to find the single best picture, but a chance to show how differently people see the same world. On the morning the paintings went up, I walked past dozens of styles, from careful realistic portraits to ③boring, colorful abstractions, and none of them looked like mine. Instead of feeling embarrassed, I found myself ④curious about why each artist had made certain choices. Standing in that crowded hallway, I finally understood that the exhibition's real purpose was not to rank the paintings, but to let students discover how many different perspectives could exist in a single ⑤shared space.

Emergency room doctors note that scooter-related head injuries have risen sharply in recent years, closely tracking the rise in scooter popularity itself. _______________. A fall at that speed, onto pavement rather than grass, can cause a head injury just as severe as one from a bicycle or a small motorcycle.

It is often assumed that memory operates independently of bodily context, yet research suggests that this assumption deserves reconsideration. When information is learned under a particular physiological or emotional condition, _______________, a phenomenon researchers call state-dependent memory. Individuals who study while mildly anxious, for instance, often recall material more accurately when tested under similarly anxious conditions than when tested while calm, even though calmness is typically considered more conducive to concentration. This finding should prompt educators to reconsider the assumption that a single optimal testing environment exists for every learner, since matching internal states across encoding and retrieval provides retrieval cues that a mismatched state cannot supply. Critics might argue that such effects are minor and inconsistent, yet accumulated evidence across pharmacological and emotional studies is difficult to dismiss. Policymakers designing assessments should therefore weigh not only content difficulty but also the physiological continuity between preparation and examination, since ignoring this dimension risks underestimating certain students' actual knowledge.

A loud, jarring alert sound interrupting a phone's normal notifications usually means one thing: a government agency has issued an emergency text to everyone in a specific area, warning of anything from a flash flood to a missing child. (A) Some residents complain that the alerts arrive too frequently or for events that feel minor, leading a small number of people to silence the notifications altogether. (B) Safety officials warn that this response defeats the entire purpose of the system, since a person who mutes every alert for convenience will also miss the one message that truly demands immediate action. (C) These messages are designed to reach people instantly, without requiring anyone to download an app or subscribe to a service in advance, since a disaster rarely waits for someone to prepare.

As solar and wind power expand rapidly across national grids, engineers face a challenge that receives far less public attention than the construction of the generating facilities themselves. (A) One proposed solution involves large-scale battery storage systems, which absorb surplus electricity generated during periods of high output and release it later when generation declines. Another approach relies on expanding transmission networks across wider regions, so that electricity generated in a sunny area can be redirected to places experiencing a shortfall. (B) Unlike conventional power plants, which can adjust their output to match demand at almost any moment, solar panels and wind turbines generate electricity only when sunlight or wind is available, producing supply that fluctuates constantly. This intermittency means that grid operators must balance supply and demand even when renewable output suddenly drops, such as when clouds cover a solar farm or wind speeds fall. (C) Grid operators must therefore invest in infrastructure capable of accommodating this variability, rather than assuming renewable sources can simply replace fossil fuels without adjustment. Without such investment, integrating renewable energy could paradoxically undermine the very reliability that modern electricity grids are expected to provide.

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 )

This weekly ritual might sound unusual to anyone who has only ever read a novel alone. Every Wednesday evening, a small group meets in the corner of a quiet cafe, coffee cups in hand, ready to talk about a book they have all just finished. ( ① ) This is a book club, and its members insist that reading the same novel together changes the experience completely. ( ② ) Alone, a reader usually forms one interpretation and rarely questions it again. ( ③ ) In a group, however, one member's small comment about a minor character can suddenly change how everyone else understood the whole story. ( ④ ) Members also say that having a discussion planned in advance pushes them to finish books they might otherwise put down halfway through. ( ⑤ ) Perhaps the greatest benefit is social rather than literary: strangers from very different backgrounds discover that they share the same doubts, laughter, and surprises over the very same pages.

주어진 문장: This curvature reflects a broader principle: sensitivity to change diminishes as the underlying quantity grows, whether that quantity represents a gain or a loss. Prospect theory proposes that the subjective value of money is not a straight line but a curved function, differing sharply from the assumptions of classical economic models. ( ① ) In the domain of gains, the function bends downward as amounts increase, so the psychological difference between earning zero and one hundred dollars feels far greater than between earning one thousand and eleven hundred. ( ② ) A parallel pattern appears among losses, where the curve bends in the opposite direction, yet sensitivity still fades as the amount grows larger. ( ③ ) This tendency, known as diminishing sensitivity, explains why a shopper barely notices a ten dollar increase on a two thousand dollar purchase, though the same ten dollars would matter enormously as the price of a meal. ( ④ ) Researchers illustrate this curvature with graphs shaped like an S turned sideways, sloping gently near the center and flattening toward both extremes. ( ⑤ ) Understanding this curvature allows economists to predict decisions that a simple, linear model of value could never anticipate.
