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 shifts later, ①making it difficult for teenagers to fall asleep before eleven at night. Yet school start times rarely adjust to this shift, ②forcing students to wake before their bodies are ready. The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to impaired concentration, weakened memory, and a higher risk of anxiety and depression. It can also disrupt the hormones ③that regulating appetite, contributing to unhealthy weight gain over time. Some school districts have experimented with ④delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show improved grades, better mood, and fewer tardy arrivals. Despite this evidence, changing entrenched school schedules ⑤remains a slow and contentious process.

Influencer marketing has become one of the most powerful tools that companies use to reach young consumers. Unlike traditional advertisements, which often ①feel distant and impersonal, posts ②creating by influencers seem more like advice from a trusted friend. This sense of closeness, built through years of sharing daily life online, ③makes followers more willing to trust product recommendations than ordinary commercials. However, this trust can be exploited when influencers promote products they have never actually ④tried. As a result, several countries now require influencers ⑤to clearly disclose paid partnerships before posting sponsored content.

For decades, athletes were taught to stretch a muscle and hold the position before any competition, ①believing that this practice alone would prevent injury. Recent research, however, has complicated that assumption considerably. Static stretching, in which a muscle ②is held at its longest length for an extended period, can actually reduce the muscle's ability to generate explosive force immediately afterward. Dynamic stretching, which involves controlled, repeated movement through a joint's full range of motion, ③appears to prepare muscles for activity without this temporary weakening effect. As a result, many coaches now recommend ④to save static stretching for after a workout, when it may help restore muscle length and reduce soreness, while ⑤reserving dynamic movements for the warm-up period before intense effort begins.

The subscription economy refers to a business model in which consumers pay a recurring fee to access goods or services rather than owning them outright. This model has expanded ①slowly beyond entertainment platforms into areas such as clothing, food, and even transportation. Companies benefit from predictable revenue, which allows them to plan production and marketing more ②efficiently than with one-time sales. For example, a monthly clothing subscription delivers new outfits ③automatically, saving customers the time and effort of shopping in stores. However, some critics argue that subscriptions encourage people to pay for services they ④barely use. Consequently, experts recommend reviewing subscription lists ⑤regularly to avoid unnecessary expenses.

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 responsibilities that previous generations rarely encountered, since a single careless decision can expose millions of people's private information. Regardless of which approach prevails, most experts agree that ___________. Universities have begun adding data ethics courses to computer science programs, recognizing that future employees will need to balance innovation with responsibility.

Modern sports wearables continuously collect data that would once have required a laboratory to measure, allowing coaches to detect early warning signs of overtraining, sometimes noticing a decline in performance before the athlete consciously feels tired. However, the flood of data has created a new challenge: _______________. Some researchers worry that casual users may misinterpret a single unusual reading as a serious problem, leading to needless anxiety rather than useful insight.

Parents and coaches sometimes worry that heavy resistance training might damage the growth plates in a young athlete's bones, cartilage regions near the ends of long bones responsible for lengthening as a child develops. This concern kept strength training out of many youth programs for decades. However, extensive research over the past twenty years has found little evidence that properly supervised resistance training harms growth plates in healthy children, since _______________. Major pediatric and sports medicine organizations now generally agree that structured strength programs, when taught with correct form and appropriate weight, can safely improve bone density, coordination, and injury resistance in young athletes.

Attitudes toward buying used goods have changed dramatically over the past decade. (A) As a result, secondhand shopping has shed much of the stigma it once carried among younger consumers. (B) In the past, purchasing used items was often seen as a sign of financial hardship rather than a deliberate choice. (C) Today, many young shoppers proudly describe their secondhand purchases as smart, sustainable decisions.

The rapid rise of the gig economy has led researchers to examine both its opportunities and its risks. (A) In addition, because their income depends heavily on the number of tasks completed, many gig workers find it difficult to save money consistently. (B) On the positive side, gig platforms allow workers to set their own schedules and take on projects that match their skills. (C) Yet this freedom comes at a price, since most gig workers are not entitled to employer-provided benefits like health insurance.

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.
