As companies collect enormous amounts of personal data to improve their products and target advertisements, serious ethical questions ①have emerged about how that information should be handled. Employees who work with big data now face responsibilities ②that 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 ③slow innovation and increase costs for businesses. Others insist that self-regulation within companies, guided by clear ethical training, can ④protects consumers just as effectively without stifling progress. Universities have begun adding data ethics courses to computer science programs, ⑤recognizing that future employees will need to balance innovation with responsibility.

A navigation app calculating a route rarely relies on distance alone; instead, it constantly weighs real-time traffic reports, past congestion patterns for that time of day, and even data from other drivers' phones ①currently on the road. This flood of information allows the app ②to reroute a driver away from a sudden accident within seconds, often before the driver has any idea the accident ③occurring at all. The convenience comes at a cost that few passengers consider, however. When thousands of drivers are simultaneously ④redirected onto the same shortcut, that quiet side street can quickly become as congested as the highway it was meant to help travelers avoid. Residents of these once-quiet neighborhoods have increasingly complained about the sudden surge of unfamiliar traffic, ⑤arguing that an algorithm optimizing for individual convenience can end up creating a new problem.

For centuries, dreams have ①fascinated scientists and philosophers alike, yet no single theory fully explains why the sleeping brain generates such vivid and often bizarre experiences. One prominent idea suggests that dreaming helps the brain process emotional experiences, replaying difficult events in a ②safe, low-stakes environment so that their emotional intensity gradually fades. Another theory proposes that dreams serve a more practical function, allowing the brain to ③ignore responses to threats without any real danger, a kind of nightly simulation that may have offered early humans a survival advantage. Still other researchers argue that dreaming is simply a byproduct of the brain organizing memories, with vivid imagery arising as the mind sorts through the day's ④information rather than serving any independent purpose of its own. Because these theories rest on indirect evidence, none has been ⑤conclusively proven.

These platforms allow individuals to sell clothing, electronics, and furniture directly to other consumers, cutting out traditional retail markups entirely. For younger buyers especially, purchasing secondhand items has become associated with ①resourcefulness rather than financial necessity. However, buying secondhand carries certain ②risks, 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 ③vague rating systems for sellers. As ④trust in these systems continues to grow, secondhand trading is expected to ⑤expand even further in the coming years.

Across the world, teenagers are chronically short on sleep, often getting two or three hours less than the eight to ten hours experts recommend for their age. Part of the problem lies in biology: as puberty begins, the body's internal clock naturally ①shifts later, making it difficult for teenagers to fall asleep before eleven at night. Yet school start times rarely adjust to this shift, forcing students to wake before their bodies are ready. The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to ②impaired concentration, weakened memory, and a higher risk of anxiety and depression. It can also disrupt the hormones that regulate appetite, contributing to ③unhealthy weight gain over time. Some school districts have experimented with delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show ④worsened grades, better mood, and fewer tardy arrivals. Despite this evidence, changing entrenched school schedules remains a slow and ⑤contentious process.

A flexitarian is someone who mainly eats plant-based meals but occasionally includes meat or fish, unlike a strict vegetarian who avoids animal products entirely. This flexible diet has recently gained attention as a practical way to fight climate change, since raising livestock produces a significant portion of global greenhouse gas emissions. Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere. By replacing just a few meat-based meals each week with vegetables, grains, or legumes, individuals can noticeably shrink their carbon footprint without giving up meat completely. Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that _______________.

When Mina graduated from college five years ago, she had never even heard the term "data scientist." Everything changed when a small tech startup, which was building an app to predict traffic patterns, hired her to analyze massive amounts of data. Mina quickly discovered that she loved turning raw numbers into insights that helped real people make better decisions. Within two years, ___________, as companies in every industry realized how valuable data could be. Today, Mina leads a team of ten analysts, mentoring young graduates who are drawn to a field that barely existed when she began her own career.

A short nap taken in the early afternoon, often called a power nap, can noticeably sharpen attention and mood without leaving a person groggy afterward. (A) If a nap extends much beyond that window, the sleeper risks waking during deep sleep, which produces a foggy, disoriented feeling known as sleep inertia that can persist for thirty minutes or more. (B) The key lies in timing: naps limited to roughly twenty minutes allow the brain to pass through the lightest stages of sleep while avoiding the deeper stages associated with slow-wave activity. (C) Laboratory studies 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 effective. For this reason, many workplaces now designate quiet rooms where employees can recharge briefly during the day.

Goffman's original theory focused on face-to-face interaction, but researchers have expanded it to explain behavior on social media. (A) Unlike face-to-face encounters, online platforms allow users unlimited time to edit captions, retouch photos, and delete unflattering content before anyone sees it. (B) This expanded control means that online impression management can be even more deliberate and polished than anything Goffman originally observed in daily conversation. (C) As a result, some scholars argue that today's online performances create unrealistic standards that traditional face-to-face interactions never produced.

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.
