Choice architecture refers to how decisions are ①designed. It determines which option is automatically selected unless a person chooses otherwise, ②known as the default option. Research consistently shows that people tend to stick with whatever is already set, even when changing it takes only seconds. Organ donation is a well-known example. Countries ③which citizens are automatically registered as donors unless they opt out show much higher donation rates than opt-in countries. Retirement savings programs show a similar pattern, since employees ④automatically enrolled in a pension plan rarely cancel it. Voluntary sign-ups, in contrast, often delay indefinitely. Critics argue that default options can be manipulated to benefit companies, so transparency about how defaults are chosen becomes essential, and supporters insist it should be designed ⑤to support people's long-term interests.

Insomnia is rarely caused by a single factor; it usually emerges from an interaction between psychological stress and physiological arousal that ①keeps the body from settling into sleep. A common trigger is what researchers call cognitive hyperarousal, in which the mind continues ②to racing with worries about work, relationships, or even the inability to sleep itself, creating a frustrating cycle where anxiety about insomnia becomes a cause of insomnia. At the same time, the body's stress response system can become chronically activated, ③releasing hormones such as cortisol that keep heart rate and body temperature elevated at night, both of which interfere with the natural drop in arousal needed to fall asleep. Poor sleep habits, including irregular bedtimes and excessive screen use before bed, can further ④weaken the body's internal signals for sleep onset. Because these psychological and physiological factors reinforce one another, effective treatment for chronic insomnia addresses both the racing mind and the underlying pattern of physical tension, rather than ⑤relying on medication alone.

Every day, email providers quietly block billions of unwanted messages before they ever reach a user's inbox. The filter examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks. What makes the system effective is that it keeps learning after launch: whenever a user marks a message as spam, that action becomes new training data, sharpening the filter's future decisions. This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. As a result, _______________.

Elite athletes often perform in front of enormous crowds with championships, contracts, and years of training riding on a single moment, and the psychological weight of that pressure can undermine skills that feel automatic in practice. Sports psychologists explain that intense anxiety narrows attention and disrupts the smooth, unconscious execution of well-learned movements, a phenomenon sometimes called choking under pressure. Rather than trying to eliminate nervousness entirely, which research suggests is nearly impossible, many trainers now teach athletes to _______________. Structured breathing exercises and pre-performance routines also help athletes regain a sense of control before a decisive moment.

Sleep debt refers to the cumulative gap between the amount of sleep a person needs and the amount they actually get. (A) Unlike a financial debt, however, this deficit cannot simply be repaid with a single long weekend of rest. (B) 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 the resulting impairment in attention and mood can resemble that of a person who has been awake for an entire night. (C) 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.

Some changes in habit begin not with a big decision but with a quiet moment that lingers in the mind. (A) That changed when her class was assigned a documentary about plastic waste drifting through the ocean, footage she initially expected to find boring. Instead, watching seabirds mistake plastic fragments for food left her strangely unsettled, and she found herself thinking about the assignment long after class ended. (B) The next morning, almost without deciding to, she slipped her old tumbler into her backpack instead of buying a disposable cup on the way to school. It felt like a small, meaningless gesture at first. However, as weeks passed, she realized that consistently choosing the tumbler, declining a plastic straw, and reusing a shopping bag were quietly adding up. Small choices, she discovered, become meaningful once repeated. (C) Until last spring, Minji rarely thought twice about tossing a paper cup into the trash after finishing her coffee. Environmental issues seemed distant, something scientists and politicians should handle rather than an ordinary student like her.

The subscription economy has changed the way many people think about ownership. (A) As a result, companies can predict their income more accurately and plan their operations accordingly. (B) Rather than buying products outright, consumers increasingly prefer paying small recurring fees for continued access. (C) This shift benefits businesses as well, since steady monthly payments create a stable source of revenue.

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.

Yet the number displayed each morning is only as good as the estimate behind it. Wearable devices that track sleep have become enormously popular, promising a detailed breakdown of light, deep, and REM sleep each night. ( ① ) These gadgets typically rely on movement sensors and heart rate monitors to estimate sleep stages, since directly measuring brain activity would require equipment found only in a sleep laboratory. ( ② ) This indirect approach, however, introduces significant uncertainty. ( ③ ) Independent studies comparing wearable data with polysomnography, the gold-standard method used in clinical sleep labs, have found that consumer devices are reasonably accurate at distinguishing sleep from wakefulness but considerably less reliable at identifying specific sleep stages. ( ④ ) Some trackers overestimate deep sleep, while others underestimate the amount of time spent in REM sleep, and the margin of error can vary widely between brands. ( ⑤ ) Despite these limitations, many users have come to treat the nightly score generated by their device as an objective medical verdict, sometimes experiencing anxiety when the number falls below what they expect, a phenomenon researchers have begun calling orthosomnia.

주어진 문장: The sudden attention was overwhelming, but it also opened doors she had never imagined. Soojin started posting short cooking videos on her phone during her last year of high school, never imagining it could become a career. ( ① ) At first, only a handful of friends watched her clips, and she nearly quit after several months without noticeable growth. ( ② ) She kept experimenting, however, adjusting her editing style and posting more consistently despite the discouraging numbers. Everything changed when one video demonstrating a simple recipe unexpectedly reached millions of viewers overnight. ( ③ ) Brands began contacting her, offering payment in exchange for featuring their products in future videos. ( ④ ) Within a year, Soojin was earning more from her online content than most entry-level jobs would have paid her. ( ⑤ ) Still, she quickly learned that being a creator demanded constant work, since algorithms rewarded frequent uploads and audiences expected fresh content daily.
