Opening most camera apps today reveals a row of filters that can smooth skin, brighten eyes, and reshape a jawline before a photo is even taken, all powered by AI models ① trained to recognize facial features in real time. What began as a playful novelty has become a default setting for many users, subtly ② adjusting nearly every selfie posted online. Psychologists have grown concerned about a specific consequence of this shift: people increasingly compare their unfiltered reflection in a mirror to a filtered version of themselves ③ seeing constantly on a screen, a comparison that earlier generations never had to face. Some social media platforms have responded by ④ labeling heavily edited photos or banning certain filters that alter body shape. Whether such small warnings can meaningfully counter the daily flood of filtered images, however, ⑤ remains an open question that researchers are only beginning to study.

A short nap taken in the early afternoon, often called a power nap, can noticeably sharpen attention and mood without ① leaving a person groggy afterward. The key lies in timing: naps limited to roughly twenty minutes allow the brain ② to pass through the lightest stages of sleep while avoiding the deeper stages associated with slow-wave activity. If a nap extends much beyond that window, the sleeper risks ③ waking during deep sleep, which produces a foggy, disoriented feeling known as sleep inertia that can persist for thirty minutes or more. Laboratory studies ④ comparing napping and non-napping groups have repeatedly shown that a brief nap improves reaction time and short-term memory almost as effectively as a full night of extra rest. Interestingly, the benefit appears strongest when the nap occurs several hours after waking, since this is when the body's natural dip in alertness makes rest most ⑤ effectively.

As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions have emerged about how that information should be handled. Employees who work with big data now face ①minimal responsibilities that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. Some argue that strict regulations should govern data collection, even if such rules ②slow innovation and increase costs for businesses. Others insist that self-regulation within companies, guided by clear ethical training, can protect consumers just as ③effectively without stifling progress. Most experts agree that professionals handling sensitive data must be trained not only in technical skills but also in ethical ④decision-making. Universities have begun adding data ethics courses, recognizing that future employees will need to ⑤balance innovation with responsibility.

Melatonin is a hormone produced by a small gland deep within the brain, and its release follows a remarkably ① unpredictable daily pattern. Levels stay low throughout the bright hours of the day, begin rising in the evening as darkness falls, peak in the middle of the night, and then ② decline again as morning approaches. This rhythm is controlled primarily by light: specialized cells in the eye detect brightness and send signals that either permit or suppress melatonin production, which is why exposure to bright screens late at night can ③ delay its release and make falling asleep more difficult. Unlike some hormones that directly cause the body to perform a task, melatonin does not force sleep to occur; instead, it signals to the rest of the body that night has arrived, preparing various systems to shift into a ④ lower-energy state. Because of this signaling role, taking melatonin supplements at the wrong time can shift a person's internal clock in the ⑤ opposite direction from what was intended.

When people consistently sleep too little, the body's hormonal balance shifts in ways that can ① quietly encourage weight gain. Two hormones in particular play ② opposing roles in regulating appetite: leptin signals fullness to the brain, while ghrelin stimulates the sensation of hunger. Studies show that sleep deprivation lowers leptin levels while raising ghrelin levels, so a tired body ends up feeling ③ fuller than it actually needs to be, even after a normal-sized meal. At the same time, insufficient sleep interferes with how efficiently the body processes glucose, making cells less ④ responsive to insulin and leaving more sugar circulating in the bloodstream than usual. Over months or years, this combination of increased appetite and reduced insulin sensitivity can contribute to steady weight gain and raise the risk of developing type 2 diabetes. Because these effects build up so ⑤ gradually, many people never connect their shifting eating habits or worsening blood sugar to something as ordinary as a few lost hours of sleep each night.

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, _______________.

Airlines and other companies often invite customers to pay a small extra fee to offset the carbon released by their trips. (A) As a result, purchasing an offset can become a convenient way to avoid making harder, more meaningful changes to one's actual carbon footprint. (B) This option relies on carbon offsets, credits that fund projects like tree planting or renewable energy in exchange for supposedly canceling out one's own emissions. (C) Critics point out, however, that many such projects would have occurred regardless of the funding, meaning the offset achieves little real, additional benefit.

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.

The growing presence of AI in creative fields has sparked lively discussion among artists and critics alike. (A) In contrast, some artists worry that relying too heavily on such tools may weaken the value placed on original human creativity. (B) Many artists have embraced AI as a way to explore new styles quickly and overcome creative blocks. (C) Given these opposing views, most experts now agree that AI works best as a partner rather than a replacement for human creators.

주어진 문장: Yet not every worker benefits equally from these changes. Automation is transforming labor markets more quickly than economists predicted a decade ago. ( ① ) Factories once staffed by hundreds of workers now rely on robotic arms that assemble products with remarkable precision. ( ② ) This shift does not simply eliminate jobs; it also creates roles that never existed before, such as technicians who maintain robotic equipment. ( ③ ) Companies that invested early in automation often report steady increases in productivity, since machines handle repetitive tasks while employees focus on creative problem-solving. ( ④ ) Policymakers argue that retraining programs are essential to help displaced workers move into emerging fields. ( ⑤ ) Without such support, the benefits of automation may not be shared fairly across society.
