Psychologists who study daily behavior describe habits through a model ①called the cue-routine-reward loop. This theory explains that every habit begins with a cue, a signal that ②tell the brain to start an automatic behavior. The brain then performs a routine, ③which is the action itself, whether physical or mental. Finally, the brain receives a reward, a positive feeling that makes it want ④to repeat the same behavior. For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run without conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. Understanding this structure helps people redesign daily patterns more effectively than ⑤relying on willpower alone.

Time-management researchers frequently mention a principle ①known as Parkinson's Law, which states that work expands to fill the time available for its completion. According to this idea, a task that could be finished in one hour will often stretch to fill an entire afternoon if that much time ②is scheduled for it. Students who set vague deadlines frequently experience this effect, spending extra hours ③refined a report that was already complete. Employees given a full week for a simple project may also delay meaningful progress until the final days, even though the actual work ④requires far less effort. This pattern happens partly because people unconsciously adjust their pace to match perceived urgency. Setting shorter, more specific deadlines can counter this tendency, forcing tasks to fit within a tighter and more realistic window. By recognizing how flexible time encourages unnecessary delay, individuals can complete assignments more efficiently ⑤without sacrificing quality.

As technology continues to reshape nearly every profession, the idea of finishing education after graduation ①has become outdated. Workers who once expected their initial training to last an entire career now find that skills can become obsolete within just a few years. Many professionals now take short online courses, attend workshops, or ②earn new certifications while continuing to work full-time. Companies that support this kind of continuous education often benefit as well, since employees ③bring fresh knowledge back into their daily tasks. Critics argue that constant learning can be exhausting and ④difficultly to balance with personal responsibilities. Nevertheless, most career experts insist that those who resist ongoing education risk ⑤falling behind their peers.

Telemedicine, which allows patients to consult doctors through video calls rather than in-person visits, ①have expanded rapidly since its early adoption. Supporters argue that this approach saves patients considerable time and ②makes healthcare accessible to people living in remote areas without nearby hospitals. It has also created new career opportunities, ③since healthcare providers now need staff skilled in digital communication. However, critics contend that virtual appointments cannot fully replace physical examinations, ④which remain essential for detecting certain conditions. Despite such concerns, most healthcare experts believe telemedicine will continue to grow, ⑤complementing rather than replacing traditional in-person care.

Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle that ①governs when we feel alert and when we feel drowsy. This clock is regulated primarily by a tiny cluster of neurons in the brain that responds to light entering through the eyes. When morning sunlight strikes the retina, the cluster signals the body to ②suppress sleep hormones and raise body temperature, preparing us for activity. As evening approaches and light fades, the same mechanism triggers the release of melatonin, a hormone that ③promotes drowsiness. Because this rhythm evolved around the natural cycle of day and night, modern habits such as staying indoors under artificial light or working night shifts can push the internal clock ④out of sync with the external environment. Such misalignment does not simply cause tiredness; it has also been associated with digestive problems and ⑤heightened concentration, suggesting that timing matters as much as total sleep hours.

Smartphones, tablets, and computer screens all emit a significant amount of blue light, a short-wavelength light that our eyes are especially sensitive to. During the day, exposure to blue light from the sun helps keep us alert and mentally sharp, which is generally beneficial. At night, however, the same wavelength can interfere with the body's natural preparation for sleep. Specialized cells in the retina detect blue light and send signals to the brain's internal clock, which results in _______________. Studies have found that people who scroll through their phones in bed before sleeping take longer to fall asleep and experience lighter, more easily disrupted sleep than those who avoid screens. Some devices now offer a night mode that shifts the display toward warmer tones, reducing blue light output in the evening. While this feature may help slightly, sleep researchers generally recommend limiting screen use altogether in the hour before bedtime for the best results.

Secondhand trading platforms, once considered a niche market for used goods, have grown into a mainstream part of consumer culture. Rising prices for new products, combined with growing awareness of environmental waste, have encouraged many shoppers to consider used items before purchasing something brand new. These platforms allow individuals to sell clothing, electronics, and furniture directly to other consumers, cutting out traditional retail markups entirely. However, buying secondhand carries certain risks, since items cannot always be inspected closely before purchase, and some sellers misrepresent the condition of their products. To address this problem, many platforms now offer buyer protection programs and detailed rating systems for sellers. As trust in these systems continues to grow, ___________.

Social media algorithms are designed to keep users engaged by showing them content they are likely to enjoy. (A) As a result, users are gradually exposed to a narrower and narrower range of perspectives over time. (B) This pattern, known as an echo chamber, can eventually lead to greater political polarization within a society. (C) To achieve this goal, the algorithms recommend posts and articles similar to what a user has already liked or shared.

Every day, email providers quietly block billions of unwanted messages before they ever reach a user's inbox, a task that would be impossible without an AI filtering system running constantly in the background. (A) This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. (B) The filter examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks that scammers commonly rely on to slip past detection. (C) What makes the system effective is that it keeps learning after launch, since a user's action of marking or rescuing a message becomes new training data.

주어진 문장: Many of them said they had simply seen photos online and wanted to experience the space for themselves. Last spring, a small cosmetics brand opened a pop-up store in a busy shopping district for just two weeks. ( ① ) Rather than displaying products in the usual manner, the team designed the space to resemble a colorful garden, inviting visitors to explore and take photographs. ( ② ) Word spread quickly through social media as customers shared images of the unusual setting with their friends and followers. ( ③ ) Lines formed outside the store within days, even though the products themselves were already available online. ( ④ ) Curious about this success, a marketing researcher later interviewed several visitors, who explained that the temporary nature of the event made the experience feel special. ( ⑤ ) Many admitted they had never previously purchased from the brand but decided to buy something simply to remember the visit.
