Every plastic product carries a small recycling mark, but few students know ①what these marks mean. Each symbol contains a number ②that shows what material the item is made of. Reading these marks is similar to ③reading nutrition labels on snacks, which tell you exactly what is inside. Likewise, ④throwing plastic away without checking its mark can send a reusable item straight to a landfill. Some marks even show that a material cannot be recycled at all, so it must ⑤sorted separately.

Many large companies now rely on artificial intelligence to screen job applications before a human ever sees them. These systems promise ①efficiency, scanning thousands of resumes in seconds and ranking candidates according to patterns drawn from previous hiring decisions. However, this reliance on historical data creates a ②troubling risk. If a company's past hiring favored a particular group, the algorithm may learn to treat that pattern as a marker of success and ③loudly reproduce it, even when no one intended discrimination. Unlike a human interviewer, the system offers no explanation for its choices, which makes the bias ④difficult to detect until an outside audit reveals it. Some researchers argue that fairness cannot be added afterward; it must be built into the system's design from the very ⑤beginning.

Financial markets occasionally experience episodes in which asset prices rise far beyond any level that careful analysis of underlying fundamentals could justify, a phenomenon commonly attributed to herd psychology. During such episodes, individual investors, observing that prices have already risen substantially, often conclude that continuing to buy is ①reasonable simply because so many others are doing the same, rather than because any independent evaluation supports the purchase. This dynamic can become self-perpetuating: rising prices attract new buyers, whose purchases push prices higher still, thereby attracting yet another wave of buyers convinced that the upward trend itself constitutes ②reliable evidence of underlying value. Historical episodes of speculative excess display a strikingly similar pattern, suggesting that the underlying psychological mechanism remains ③variable even as the specific assets involved change considerably across centuries. Eventually, however, some triggering event, however minor, prompts a portion of investors to ④reconsider their assumptions, and the resulting wave of selling can trigger a collapse every bit as rapid and self-reinforcing as the original ⑤ascent.

Sociologist Mark Granovetter introduced an idea that seems contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. This happens because strong ties tend to share the same social circles and, therefore, already possess similar knowledge. Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. Social media platforms have made maintaining such connections remarkably easier, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms _______________.

Imagine two travelers preparing for the same trip: one refuses to fly after watching news coverage of a recent plane crash, while the other books a flight without hesitation. Statistically, air travel remains far safer than driving the same distance by car, yet vivid, emotionally charged images tend to dominate human judgment more powerfully than dry statistics ever could. This tendency, in which people estimate how likely an event is based on _______________, quietly shapes countless everyday decisions. News broadcasts that repeatedly feature rare disasters can leave viewers convinced that such events are common, even though official records clearly show the opposite. Advertisers and politicians alike exploit this pattern, knowing that a single striking anecdote often persuades audiences more effectively than pages of careful statistics ever manage to.

Every summer, doctors warn about the danger of heatstroke, a serious condition in which ___________. This condition can be life-threatening if it is not treated quickly. To prevent heatstroke, drink plenty of water throughout the day, avoid outdoor activities during the hottest hours, and wear light, loose clothing.

Riding a bicycle is a great way to stay active during summer vacation, but ___________. Before you ride, check that your tires are properly inflated and your brakes are working well. Wearing a helmet is essential, since it can prevent serious head injuries in an accident.

주어진 문장: This shows that expertise alone does not guarantee immunity from such intuitive shortcuts. Suppose you meet a quiet, gentle man who speaks softly, tends a small garden, and organizes his bookshelf with meticulous care. ( ① ) Asked whether he is more likely a florist or a truck driver, most people instinctively choose florist, since his personality matches the stereotype so neatly. ( ② ) This judgment, however, ignores a crucial fact: truck drivers vastly outnumber florists in almost every country, which means that, statistically, he is far more likely to belong to the larger group regardless of how well he fits the flower-shop image. ( ③ ) Relying on resemblance to a familiar category rather than on underlying numerical proportions, known among researchers as representativeness, leads people to overlook these base rates almost automatically. ( ④ ) Even trained professionals, who should know better, often fall into the same trap when a vivid description feels more convincing than plain statistics. ( ⑤ ) Consequently, teaching people to pause and ask how common something actually is, instead of merely how typical it appears, can meaningfully improve the accuracy of everyday predictions and reduce costly errors in judgment.

However, even confident swimmers can get into trouble in open water. Summer is the best time to enjoy swimming pools, rivers, and beaches with family and friends. ( ① ) First, always swim in areas that are supervised by a lifeguard, and never swim alone, even if you are a strong swimmer. ( ② ) It is also important to check the weather and water conditions before entering the water, since strong currents and sudden storms can appear without warning. ( ③ ) Wearing a life jacket in open water is essential, especially for children and beginners. ( ④ ) Taking regular breaks during long swims helps prevent exhaustion. ( ⑤ ) Learning basic rescue skills is another good habit that could help you save a life someday.

주어진 문장: This was her very first trip to the region, so she had nothing to compare the scene to except old photographs taken by earlier scientists. A documentary director named Mira first traveled to a remote Arctic glacier to film its towering cliffs of blue ice, which seemed frozen in time. ( ① ) Standing before the massive wall, she assumed such an enormous structure could hardly change within a lifetime. ( ② ) Five years later, however, she returned to the very same coordinates, expecting her camera to capture an identical scene. ( ③ ) 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. ( ④ ) Comparing the two sets of footage side by side, Mira realized that a transformation she had expected to take centuries was actually happening within a single decade. ( ⑤ ) 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.
