Every cell in the human body follows an internal timer known as the circadian rhythm, a roughly twenty-four-hour cycle ①that governs when we feel alert and when we feel drowsy. This clock is regulated primarily by a tiny cluster of neurons in the brain ②that responds to light entering through the eyes. When morning sunlight strikes the retina, the cluster signals the body ③to suppress 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 ④promotes 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 out of sync with the external environment. Such misalignment does not simply cause tiredness; it has also ⑤been associated with digestive problems and reduced concentration, suggesting that timing matters as much as total sleep hours.

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. Lines formed outside the store within days, even though the products themselves were already available online. 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 and worth attending in person. When the two weeks ended, the brand reported a significant ①decrease in both sales and social media followers. ②Encouraged by these results, the company ③began planning ④additional pop-up events in ⑤other cities.

Before making a purchase, most online shoppers now read reviews written by previous customers rather than relying solely on advertisements. These reviews, posted by people who have no financial connection to the seller, often seem more trustworthy than promotional claims. Research shows that products with a large number of positive reviews sell significantly more than those with few or no reviews at all. However, fake reviews written by paid writers or even automated programs have become a serious problem, undermining consumer trust. Platforms that fail to detect these fraudulent posts risk losing credibility with their users, who expect authentic opinions when making decisions. To address this issue, several review platforms have begun using artificial intelligence to identify suspicious patterns. Ultimately, the power of online reviews ___________.

Telemedicine, which allows patients to consult doctors through video calls rather than in-person visits, has expanded rapidly since its early adoption. However, critics contend that virtual appointments cannot fully replace physical examinations, which remain essential for detecting certain conditions. Despite such concerns, most healthcare experts believe telemedicine will continue to grow, complementing rather than replacing traditional in-person care. As this shift continues, ___________.

Parkinson's Law appears frequently in everyday workplaces, often without employees even realizing it. (A) As a result, the meeting naturally stretches to fill the entire hour, even though very little new information is actually discussed. (B) This situation illustrates the law's central claim that the amount of time allotted for a task directly shapes how long the task actually takes. (C) Consider a manager who schedules an hour-long meeting to discuss a minor issue that could realistically be resolved in only a few minutes.

Introducing cobots into a factory requires careful planning to ensure both safety and productivity. (A) Once installed, however, cobots must be closely monitored, since their sensors can occasionally malfunction in noisy or crowded environments. (B) Engineers must first program the robots to recognize the exact boundaries of each worker's movement space. (C) After this initial setup, cobots can be integrated gradually, starting with simple tasks before taking on more complex ones.

The pace of technological change has forced professionals to rethink how they approach their careers. (A) As a result, many now treat learning as an ongoing part of their careers rather than something that ends at graduation. (B) A skill considered valuable just five years ago may already be outdated today, forcing workers to update their knowledge constantly. (C) Naturally, some professionals find this constant demand for new skills stressful and difficult to manage alongside other responsibilities.

주어진 문장: The financial and reputational damage caused by a single attack can be enormous. As more businesses move their operations online, cyberattacks have become one of the most serious threats facing modern companies. ( ① ) Hackers now target everything from small retail websites to massive financial institutions, stealing sensitive data or demanding ransom payments. ( ② ) In response, demand for cybersecurity professionals has surged across nearly every industry. ( ③ ) These specialists design systems that detect suspicious activity, patch vulnerabilities before criminals can exploit them, and train employees to recognize phishing attempts. ( ④ ) Universities have responded by creating specialized degree programs, while many companies now offer scholarships to attract students into this growing field. ( ⑤ ) Despite this expansion, experts estimate that millions of cybersecurity positions worldwide remain unfilled.

주어진 문장: Few shoppers realize how deliberately these small details are arranged to influence their behavior. Retailers use a variety of techniques designed to encourage customers to make unplanned purchases. ( ① ) Placing small, inexpensive items near checkout counters, for example, tempts shoppers who are already waiting in line with little else to do. ( ② ) Online stores achieve a similar effect through countdown timers that create a false sense of urgency, suggesting that a deal will vanish within minutes. ( ③ ) Bright colors, cheerful music, and pleasant scents are also carefully chosen to put customers in a relaxed mood. ( ④ ) Critics argue that these tactics exploit human psychology rather than genuinely informing consumers about a product's value. ( ⑤ ) Supporters of the industry insist that such techniques merely make shopping more enjoyable.

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.
