Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims ①turn out to be misleading. This practice, known as greenwashing, ②occurs when a business spends more effort marketing its products as eco-friendly than actually reducing environmental harm. A company might launch a recycled-packaging line while ③continuing to pollute rivers through its main factories, creating a false impression of genuine change. Such tactics deceive well-intentioned consumers who wish to shop responsibly but ④lacks the tools to verify corporate claims. In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, ⑤allowing outsiders to check their progress.

When Daniel was a child, he dreamed of becoming an astronaut, yet he assumed such careers ①belonged only to a handful of government scientists. By the time he entered university, however, the space industry had changed dramatically, as private companies began ②launching satellites and building reusable rockets. Daniel studied aerospace engineering, ③drawing to the idea that space exploration was no longer limited to a few national agencies. During an internship, he helped design a small satellite ④intended to monitor crop health from orbit. He realized that the space industry now needed not only pilots and engineers but also data analysts and technicians ⑤familiar with international space regulations.

Three-dimensional printing technology is changing how products are designed and manufactured across many industries. Unlike traditional manufacturing, ①which often requires expensive molds and long production times, 3D printers can create complex objects directly from digital files within hours. This flexibility allows companies ②to produce small batches of customized products without the massive costs typically associated with mass production. Hospitals now use 3D printing to create prosthetic limbs ③tailored precisely to individual patients, while automakers use it to build lightweight parts that reduce vehicle weight. Small businesses, too, have benefited enormously, since the technology ④lower the barrier to entry for entrepreneurs. As printing materials improve and machines become faster, the technology is expected ⑤to play an increasingly central role in future manufacturing.

When Mina graduated from college five years ago, she had never even heard the term "data scientist." She had studied statistics simply because she ①enjoying solving puzzles with numbers. Everything changed when a small tech startup, ②which was building an app to predict traffic patterns, hired her to analyze massive amounts of data. Mina quickly discovered that she loved ③turning raw numbers into insights that helped real people make better decisions. Within two years, demand for professionals like her ④had exploded, as companies in every industry realized how valuable data could be. Today, Mina leads a team of ten analysts, ⑤mentoring young graduates who are drawn to a field that barely existed.

Many teenagers check their social media accounts dozens of times a day, worried that they might miss something ①important happening among their friends. This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of ②loneliness and regret, even though the event has already ended. Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. Moreover, this endless comparison with curated highlights of other people's lives tends to ③deepen feelings of anxiety rather than ④worsen them. Therefore, students should learn to ⑤limit their social media use and focus more attention on the relationships and activities directly in front of them.

Exercise does far more than strengthen muscles and the heart; it also produces measurable changes within the brain itself. During sustained physical activity, the body releases a protein called brain-derived neurotrophic factor, which supports the growth of new neurons and strengthens connections between existing ones, particularly in regions associated with memory and learning. Studies comparing physically active students to sedentary peers have repeatedly found that _______________, even when the exercise session ends well before the test begins. Researchers believe that exercise increases blood flow to the brain, delivering oxygen and nutrients more efficiently, while also reducing levels of stress hormones that can interfere with clear thinking.

Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, produces a wide range of benefits that extend well beyond simple calorie burning. (A) This adaptation explains why trained athletes often have a much lower resting heart rate than sedentary individuals of the same age. (B) Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, delivering the same amount of oxygen to working muscles while beating fewer times per minute. (C) Most fundamentally, it strengthens the heart itself, forcing it to pump larger volumes of blood with each beat.

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: Still, the risk of falling behind outweighs the discomfort of constant adjustment, most experts say. As technology continues to reshape nearly every profession, the idea of finishing education after graduation has become outdated. ( ① ) Workers who once expected their initial training to last an entire career now find that skills can become obsolete within just a few years. ( ② ) Lifelong learning, therefore, has shifted from being an optional pursuit to a practical necessity for staying competitive in the job market. ( ③ ) Many professionals now take short online courses, attend workshops, or earn new certifications while continuing to work full-time. ( ④ ) Critics argue that constant learning can be exhausting and difficult to balance with personal responsibilities. ( ⑤ ) In a rapidly changing economy, the ability to learn continuously may matter more than any single degree.

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.
