Modern advertising increasingly relies on personal data ①collected from users' browsing habits, search histories, and social media activity. Companies argue that this approach benefits consumers by showing advertisements that are more relevant to their actual interests. However, many critics contend that this level of tracking raises serious concerns about privacy, since users rarely understand how extensively their behavior ②is being monitored. Some algorithms can predict purchasing decisions before consumers themselves are consciously aware of them, ③which feel unsettling to many people. Furthermore, personalized advertising can trap users in a narrow bubble, repeatedly showing them similar products and ④limiting their exposure to alternatives. Supporters counter that consumers who dislike targeted ads can simply ⑤adjust their privacy settings.

Companies that ignore these concerns risk public backlash, especially when unethical practices are ①exposed through investigative journalism or social media. Real accountability, according to many experts, requires independent verification rather than self-reported claims that ②can be easily checked. Consumers, for their part, must also remain ③vigilant, since a company's marketing language does not always match its actual practices. When ethical claims are verified and accurate, however, they can build meaningful ④trust between a brand and its customers. Ultimately, corporate responsibility should be treated as an ⑤ongoing commitment rather than a marketing strategy.

When Minji was in ninth grade, she posted a joking comment ①praising a classmate's photo, never imagining anyone would remember it later. During the interview, however, one teacher mentioned having seen an old, ②unkind comment under Minji's name while reviewing applicants' profiles. ③Startled, Minji realized that everything she had ever posted online had quietly accumulated into what is called a digital footprint. Although she ④deleted the comment immediately, the damage to her reputation had already been done. She understood that digital footprints rarely disappear completely, because screenshots and memories often ⑤outlast the content itself.

Limited-edition products are goods that are released in small quantities for a ①short period of time. Many companies use this strategy because scarcity naturally ②decreases how much people desire an item. When consumers believe that a product will disappear soon, they often feel ③pressured to buy it immediately rather than wait. This excitement is ④intensified by social media, where people proudly share photos of items that others could not obtain. As a result, some shoppers later ⑤regret spending money on products they rarely use afterward.

Wearable devices that track sleep have become enormously popular, promising a detailed breakdown of light, deep, and REM sleep each night. 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. This indirect approach, however, introduces significant uncertainty. Independent studies comparing wearable data with polysomnography, the gold-standard method used in clinical sleep labs, have found that _______________. 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. 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.

Sociologist Erving Goffman argued that people constantly perform for others, much like actors managing their image on a stage, a concept known as impression management. This idea applies vividly to social media, where users select flattering photos and delete posts that might damage their reputation. Such careful curation allows people to present an idealized version of themselves that emphasizes achievements while hiding struggles or ordinary moments. However, when this performance becomes constant, a troubling gap can form between one's authentic self and the polished character displayed online. Maintaining that gap requires considerable emotional energy, and studies suggest it often leads to anxiety and exhaustion. Furthermore, comparing one's own carefully staged life to others' equally staged posts can distort what people believe is normal. Therefore, _______________.

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 owned. Frustrated, she decided to try a minimalist lifestyle, keeping only objects that served a clear purpose or brought her genuine joy. Gradually, however, she noticed that her small apartment felt calmer and easier to manage. She also realized that she spent significantly less money once she stopped buying things impulsively to fill emotional gaps. Inspired by her experience, several of her friends began adopting similar habits, questioning purchases they once made without thinking. Jina's story reflects ___________.

Until last spring, Minji rarely thought twice about tossing a paper cup into the trash after finishing her coffee. _______________. 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. 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.

Whether such small warnings can meaningfully counter the daily flood of filtered images, however, remains an open question that researchers are only beginning to study. 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 trained to recognize facial features in real time. ( ① ) What began as a playful novelty has become a default setting for many users, subtly adjusting nearly every selfie posted online. ( ② ) 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 seen constantly on a screen. ( ③ ) This is a comparison that earlier generations never had to face. ( ④ ) Some social media platforms have responded by labeling heavily edited photos or banning certain filters that alter body shape. ( ⑤ )

This mismatch between internal time and local time is the true source of the problem, not the flight itself. Travelers who cross several time zones in a single flight often arrive feeling exhausted, foggy, and strangely out of sync with the local clock, a condition widely known as jet lag. ( ① ) The discomfort arises because the body's internal clock, which governs sleep, hunger, and alertness, continues to run on the schedule of the departure city even after landing. ( ② ) Realigning this internal clock to a new time zone is not instantaneous; researchers estimate that the body typically needs about one day to adjust for every time zone crossed. ( ③ ) Flying eastward tends to produce more severe symptoms than flying westward, because advancing the internal clock forward is generally harder for the body than delaying it. ( ④ ) Exposure to natural light at the right moments after arrival can help speed up the adjustment, since light is the strongest external cue the internal clock uses to reset itself. ( ⑤ ) Without such adjustments, travelers may continue to experience disrupted sleep and reduced concentration for several days after a long international flight.
