Many people feel a sudden wave of anxiety when their smartphone battery is nearly dead or they have ①left it at home. This intense discomfort, known as nomophobia, is short for "no-mobile-phone phobia," a term ②describing the fear of losing connection to one's phone. Researchers explain that this fear develops because smartphones have become tightly linked to social belonging; missing a notification can feel like ③be cut off from friends. For example, some students check their phones dozens of times an hour, even during class, just to confirm nothing important ④has been missed. Recognizing nomophobia as a real psychological pattern ⑤is the first step toward a healthier relationship with technology.

For centuries, dreams have fascinated scientists and philosophers alike, yet no single theory fully ①explains why the sleeping brain generates such vivid and often bizarre experiences. One prominent idea suggests that dreaming helps the brain process emotional experiences, ②replays difficult events in a safe, low-stakes environment so that their emotional intensity gradually fades. Another theory proposes that dreams serve a more practical function, ③allowing the brain to rehearse responses to threats without any real danger. Still other researchers argue that dreaming is simply a byproduct of the brain organizing memories, with vivid imagery ④arising as the mind sorts through the day's information rather than serving any independent purpose of its own. Because these theories rest on indirect evidence, none has ⑤been conclusively proven.

After a viewer finishes an episode, a streaming service rarely leaves the choice of what to watch next entirely up to chance. Instead, a recommendation algorithm ①compares 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. This approach keeps viewers ②disengaged far longer than a simple list of new releases ever could, which is precisely why streaming companies invest so heavily in refining it. The system is not without drawbacks, however. Because the algorithm favors titles similar to what a viewer already enjoys, it can quietly ③narrow someone's exposure to unfamiliar genres, directors, or cultures, creating a comfortable but repetitive bubble. Some platforms have begun inserting occasional wildcard suggestions, deliberately unrelated to past viewing habits, in an attempt to ④counteract this narrowing effect and keep recommendations from becoming too ⑤predictable.

The growing sophistication of cyberattacks has transformed cybersecurity into one of the most in-demand career fields. (A) Universities have responded to this trend by launching specialized degree programs focused entirely on cybersecurity. (B) As a result, businesses across nearly every industry now compete to hire qualified security professionals. (C) Hackers today target organizations of every size, from small retailers to major financial institutions.

Many countries and companies today have adopted the goal of carbon neutrality, aiming to balance the greenhouse gases they emit with the amount they remove from the atmosphere. (A) Achieving this goal typically requires several sequential stages rather than a single sudden action; first, organizations attempt to reduce emissions directly by replacing fossil fuels with renewable energy sources such as solar or wind power. (B) Critics argue, however, that some companies exploit offsetting too early, using it to avoid making genuine reductions, so experts insist that a credible roadmap must always prioritize actual emission cuts before relying on compensation. (C) Next, they improve efficiency throughout their operations, minimizing the energy wasted during production and transportation, and only after these measures have been maximized do most organizations turn to offsetting, funding outside projects such as reforestation.

Irving Janis, a psychologist, used the term groupthink to describe how close-knit groups sometimes make poor decisions together. (A) Trusting this shared confidence, the group moved forward without pausing to consider whether the shortcut might cause problems later. (B) In one online study group, for example, a suggestion to skip an important step was accepted almost instantly, with no one voicing concerns. (C) Only after their project was criticized for missing key information did the members recognize how strongly the group's harmony had silenced doubt.

주어진 문장: This is why a ten-minute wait for test results can feel far longer than a ten-minute conversation with a close friend. Have you ever felt a boring class lasted forever while an exciting weekend disappeared in an instant? ( ① ) This common experience reflects what psychologists call the distortion of time perception: subjective time can differ from actual clock time. ( ② ) Researchers explain that people who focus intensely on an enjoyable activity process fewer separate moments, so time seems to pass quickly. ( ③ ) In contrast, bored or anxious people pay closer attention to each moment, making time feel as though it is dragging. ( ④ ) When people become deeply engaged in a task, they often lose track of time, unaware of how many minutes have passed. For example, athletes and musicians often say that hours felt like minutes while they were fully absorbed in performance. Meanwhile, students waiting anxiously for exam results describe the same few minutes as unbearably slow. ( ⑤ ) Understanding this distortion helps explain why identical time intervals can feel very different depending on mental state.

주어진 문장: Fortunately, this cycle is not impossible to reverse. An echo chamber refers to an online environment where people are mainly exposed to opinions that already match their own beliefs. ( ① ) This phenomenon occurs because social media algorithms tend to recommend content similar to what users have previously liked or shared, gradually narrowing the range of perspectives they encounter. ( ② ) As a result, individuals inside an echo chamber rarely engage with viewpoints that challenge their existing assumptions, which allows their original beliefs to grow increasingly extreme over time. ( ③ ) For example, someone who frequently reads articles supporting one political party may begin to see the opposing party as entirely unreasonable, having never seriously considered its arguments. ( ④ ) Political polarization, a significant issue in many countries today, is often linked to this pattern of selective exposure. ( ⑤ ) Breaking out of an echo chamber requires deliberately seeking information from diverse sources, even when those sources present uncomfortable or unfamiliar ideas.

주어진 문장: In other words, those who did the least to cause the problem often end up paying the highest price for it. When people discuss climate change, they often focus only on rising temperatures or melting ice, treating it as a purely scientific issue. ( ① ) However, the concept of climate justice reminds us that the causes and consequences of climate change are distributed unevenly across the globe. ( ② ) Wealthy, industrialized nations have historically released the largest share of greenhouse gases while building their economies, yet developing nations, which contributed comparatively little, frequently suffer the most severe droughts and floods. ( ③ ) This gap between responsibility and suffering raises a serious ethical question that science alone cannot answer. ( ④ ) For example, a farming community in a low-income country may lose its entire harvest to an unusual flood, even though its members have never owned a car or flown on a plane. ( ⑤ ) Therefore, tackling climate change requires more than new technology; it demands fair policies supporting the very communities least responsible for causing the crisis.

주어진 문장: This is precisely why scientists treat these thresholds with such urgency, rather than viewing them as distant, abstract possibilities. Climate scientists frequently warn about tipping points, thresholds beyond which a small additional change triggers a large, often irreversible shift in the climate system. ( ① ) Unlike gradual warming, which unfolds steadily over decades, crossing a tipping point can produce dramatic consequences within a short period. ( ② ) For instance, as Arctic ice melts, it exposes darker ocean water that absorbs more sunlight than reflective ice, accelerating further melting in a self-reinforcing cycle. ( ③ ) Similarly, scientists worry that a major ocean current, which currently redistributes heat across the planet, could slow dramatically if enough freshwater from melting glaciers dilutes the surrounding seawater. ( ④ ) Once such thresholds are crossed, restoring the original balance may become nearly impossible, even if emissions are later reduced. ( ⑤ ) Therefore, researchers argue that preventing these transitions matters more than merely slowing average temperature increases. Identifying how close each system stands to its threshold remains one of the most urgent challenges in climate research.
