An echo chamber refers to an online environment where people are mainly ①exposed to opinions that already match their own beliefs. This phenomenon occurs because social media algorithms tend to ②recommending content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. As a result, individuals inside an echo chamber rarely engage with viewpoints ③that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, ④having never seriously considered its arguments. Political polarization, a significant issue in many countries today, is often ⑤linked to this pattern of selective exposure.

Setting a goal such as 'I will study harder' rarely ①leads to meaningful improvement. According to psychologists Edwin Locke and Gary Latham, specific and challenging goals ②produce far better performance than vague or easy ones. This idea, known as goal-setting theory, suggests ③that clear targets direct attention and sustain effort over time. To apply this theory effectively, many educators recommend the SMART framework, which ④require goals to be Specific, Measurable, Achievable, Relevant, and Time-bound. Because the goal includes a clear number and a deadline, progress becomes easy ⑤to track and evaluate.

Imagine two factories making the same product: one in a country with ①**strict** carbon rules, and one in a country with almost none. The factory facing stricter rules often spends more, which can make its goods ②**pricier** than those made elsewhere. To fix this imbalance, some governments have introduced the carbon border adjustment mechanism, a policy charging imported goods a fee based on how much carbon was released while producing them. Supporters argue that the system ③**protects** domestic industries and pushes foreign manufacturers toward cleaner methods. However, critics claim it unfairly ④**benefits** developing countries, which often lack money to modernize factories quickly. For example, a small exporter in a poorer nation might struggle to pay the added charge, though it contributes ⑤**little** to global emissions. Still, if wealthier nations pair the policy with technical support, it could become a genuinely fair tool for cutting emissions worldwide.

Athletes preparing for major endurance events sometimes train for weeks at high altitude, where the air contains ① less oxygen than at sea level, in hopes of gaining a physiological edge once they return to compete at lower elevations. In this thin air, the body responds by producing ② fewer red blood cells, which carry oxygen more efficiently through the bloodstream to working muscles. When these athletes return to sea level, where oxygen is more abundant, their blood retains this elevated capacity for a limited period, potentially translating into ③ improved endurance performance. However, the benefits of altitude training are far from guaranteed, since individual athletes respond quite ④ differently to the same conditions, and some experience excessive fatigue that undermines the very training they hoped to complete. Many elite programs therefore follow a strategy known as live high, train low, in which athletes sleep at altitude to ⑤ stimulate blood adaptations but perform intense workouts at lower elevation to maintain quality and intensity.

Many people believe that a new habit becomes automatic after only twenty-one days, but researchers who examined real behavior found a different number. This project, called the 66-day habit formation study, tracked volunteers who tried to adopt a new daily habit, like drinking water with lunch. Researchers measured how automatic each action felt over time and found that habits needed ___________. Yet the actual time varied widely, ranging from about eighteen days for simple habits to over two hundred days for difficult ones. This wide range explains why the popular twenty-one-day claim, though easy to remember, rarely matches real experience.

Feed an AI music program a mood, a tempo, and a rough genre, and within seconds it can generate a complete instrumental track. (A) The software has studied thousands of existing songs, learning which chord progressions and rhythms tend to sound pleasant together, and it recombines these patterns into something new. (B) For independent creators who cannot afford a composer or expensive licensing fees, this has been a genuine breakthrough. (C) Professional musicians, however, remain divided, since a flood of AI-generated background music could quietly push human composers out of smaller, lower-budget projects.

Ethical consumption has placed new pressure on companies to justify their practices publicly. (A) Yet critics point out that such reports are sometimes little more than carefully worded public relations documents. (B) In response, many corporations now publish detailed reports describing their environmental and labor practices. (C) For this reason, many experts insist that independent audits are necessary to confirm whether ethical claims are genuine.

Climate change deniers often seem to ignore evidence that contradicts their views, and psychologists have a specific explanation for this behavior. (A) For example, someone whose job depends on fossil fuels may search for reasons to doubt the data, even while insisting that they respect science. (B) This concept, called motivated reasoning, describes how people process information in ways that protect their existing beliefs and lifestyles rather than pursue objective truth. (C) Rather than being a simple failure of intelligence, this pattern reflects a well-documented psychological tendency studied for decades.

In response, some platforms have begun inserting occasional wildcard suggestions that are deliberately unrelated to past viewing habits. After a viewer finishes an episode, a streaming service rarely leaves the choice of what to watch next entirely up to chance. ( ① ) Instead, a recommendation algorithm compares that viewer's habits with patterns drawn from millions of other users who watched similar content, then ranks thousands of titles in order of predicted interest. ( ② ) 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 refining it. ( ③ ) 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, creating a comfortable but repetitive bubble. ( ④ ) These wildcard picks are meant to counteract this narrowing effect and keep recommendations from becoming too predictable. ( ⑤ )

주어진 문장: This fear of missing out, often shortened to FOMO, drives many shoppers to act faster than they normally would. Limited-edition products are goods that are released in small quantities for a short period of time. ( ① ) Many companies use this strategy because scarcity naturally increases how much people desire an item. ( ② ) When consumers believe that a product will disappear soon, they often feel pressured to buy it immediately rather than wait. ( ③ ) For instance, a sneaker company that releases only a few thousand pairs of a special design can generate long lines outside stores overnight. ( ④ ) However, this psychological pressure can lead to purchases that are driven by fear rather than genuine need. ( ⑤ ) As a result, some shoppers later regret spending money on products they rarely use afterward.
