Many people believe that a new habit becomes automatic after only twenty-one days, but researchers who ①examined real behavior found a different number. This project, ②called 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 ③needing an average of sixty-six days to become effortless. Yet the actual time varied widely, ranging from about eighteen days for simple habits to over two hundred days for ④difficult ones. This wide range explains why the popular twenty-one-day claim, though easy ⑤to remember, rarely matches real experience.

As more businesses move their operations online, cyberattacks ①have become one of the most serious threats facing modern companies. Hackers now target everything from small retail websites to massive financial institutions, ②stealing sensitive data or demanding ransom payments. These specialists design systems ③that detect suspicious activity, patch vulnerabilities before criminals can exploit them, and train employees to recognize phishing attempts. Unlike many technical fields, cybersecurity requires constant learning, ④since hackers continually develop new methods to bypass existing defenses. Universities have responded by creating specialized degree programs, while many companies now ⑤offers scholarships to attract students into this growing field.

Have you ever noticed that an unfinished task ①keeps returning to your mind long after you stopped working? This phenomenon was first noticed by psychologist Bluma Zeigarnik, who saw ②that waiters remembered unpaid orders better than paid ones. Her observation led to what is now called the Zeigarnik effect: people remember incomplete tasks more vividly than ③completed ones. According to this theory, the mind maintains mental tension until a task reaches closure, ④keeping the unfinished task active in memory. Once the task is completed, the tension is released, and the mind ⑤let go of the details.

Jina used to fill her apartment with items she rarely used, believing that owning more things would make her happier. After moving twice within a single year, she grew exhausted from packing boxes filled with clothes she had never worn and gadgets she had forgotten she ①owned. Frustrated, she decided to try a minimalist lifestyle, ②keeping only objects that served a clear purpose or brought her genuine joy. At first, friends ③questioned why she was giving away perfectly good furniture and clothing. Gradually, however, she noticed that her small apartment ④felt calmer and easier to manage. Inspired by her experience, several of her friends began ⑤adopt similar habits, questioning purchases they once made without thinking.

Communication scholar Elisabeth Noelle-Neumann proposed the spiral of silence theory to explain why certain opinions ①dominate public discussion while others fade into invisibility. According to this theory, individuals constantly observe their surrounding environment to judge which opinions are widely accepted and which are not. When people sense that their own view belongs to a minority, they often choose to stay ②vocal rather than risk social isolation or criticism. This silence, however, creates a distorted impression that the minority opinion is even ③rarer than it actually is, discouraging additional supporters from speaking up. Over time, this cycle spirals downward, allowing the dominant opinion to appear increasingly ④unanimous while dissenting voices disappear from visible conversation. Social media platforms can intensify this spiral, since visibility metrics make popular opinions instantly ⑤noticeable while unpopular ones remain hidden.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. When someone loses two hours of sleep every night for a week, the body does not treat the shortage as fourteen separate small losses; instead, it accumulates the deficit, and _______________. Researchers have found that even modest, chronic sleep restriction gradually impairs reaction time and decision-making, often without the affected person noticing the decline. This is because subjective feelings of tiredness tend to plateau after a few days, even as objective performance keeps deteriorating. Consequently, people frequently underestimate how much sleep debt they are carrying until a demanding task suddenly exposes the accumulated cost.

Carbon neutrality refers to a state in which the amount of greenhouse gases a country or company releases into the atmosphere is balanced by the amount it removes, resulting in zero net emissions. 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. Next, they improve efficiency throughout their operations, minimizing the energy wasted during production and transportation. Only after these direct measures have been maximized do most organizations turn to _______________. Critics argue, however, that some companies exploit offsetting too early, using it to avoid making genuine reductions. Therefore, experts insist that a credible roadmap must always prioritize actual emission cuts before relying on compensation.

주어진 문장: Word of their success quickly spread beyond the village's borders. A small riverside village had endured severe flooding almost every summer, watching helplessly as rising water damaged homes and destroyed crops year after year. ( ① ) Frustrated residents eventually decided to pursue climate adaptation, adjusting their infrastructure and habits to reduce the damage caused by increasingly unpredictable weather. ( ② ) Engineers widened the drainage canals surrounding the village, allowing excess rainwater to flow away more efficiently instead of pooling in low-lying streets. ( ③ ) Meanwhile, several families whose houses stood in the most vulnerable areas relocated to higher ground, even though leaving their long-time homes was emotionally difficult. The village also installed an early warning system that sent alerts to residents' phones whenever river levels rose dangerously fast. ( ④ ) When a powerful storm struck three years later, the new measures proved effective, and the village suffered only minor damage instead of the devastating losses it had previously faced. ( ⑤ ) Their resilience became a model for neighboring communities.

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 is why many people find it especially difficult to maintain healthy eating habits after a long, stressful day at work. Psychologist Roy Baumeister proposed a concept called ego depletion theory, which suggests that willpower functions like a muscle that gradually tires after repeated use. ( ① ) According to this theory, every act of self-control, from resisting a snack to concentrating on difficult homework, draws from the same limited mental resource. ( ② ) As this resource becomes depleted throughout the day, later decisions require more effort and are more likely to fail. ( ③ ) For instance, someone who exercises discipline avoiding distractions all morning may struggle to resist checking a phone by evening. Likewise, dieters report that self-control weakens sharply at night, after hours of resisting food. ( ④ ) Some researchers argue that short breaks, adequate sleep, and blood sugar levels can help restore this depleted resource. ( ⑤ ) Although later studies have questioned how strong this effect is, the theory still offers a useful framework for understanding why willpower seems to fade throughout a long day.
