Many companies today advertise their products as environmentally friendly, yet not all of these claims are accurate. This practice, ①knowing as greenwashing, involves exaggerating or fabricating a product's positive impact on the environment. Consumers, ②who are increasingly concerned about climate change, often trust such claims without questioning them closely. As a result, they may pay higher prices for products ③that are no more sustainable than ordinary alternatives. Genuine environmental efforts, which usually ④require significant investment and long-term planning, are far more costly than simply changing a label. Therefore, governments should establish clear standards ⑤that require companies to prove their environmental claims with verifiable data.

Sleep apnea is a disorder in which breathing repeatedly stops and restarts during sleep, often because the muscles at the back of the throat relax too much and block the airway. Each pause can last from a few seconds to over a minute, and it may occur dozens of times in a single night without the sleeper ever ① waking up fully. Because these interruptions rarely produce a clear memory the next morning, many people remain ② unaware that anything is wrong, even as chronic fatigue, headaches, and irritability build up over months. Doctors therefore rely less on a patient's own account of the night and more on objective measurements, such as overnight oxygen levels and airflow patterns ③ recording in a sleep laboratory. ④ Left untreated, the disorder has been linked to serious long-term risks, including high blood pressure and heart disease, which makes an accurate diagnosis far more urgent than its subtle nighttime symptoms might ⑤ suggest.

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. What began as a playful novelty has become a ① default setting for many users, subtly 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 seen constantly on a screen, a comparison that earlier generations never had to ② face. Some social media platforms have responded by ③ labeling heavily edited photos or banning certain filters that alter body shape. Whether such small warnings can meaningfully ④ worsen the daily flood of filtered images, however, remains an ⑤ open question that researchers are only beginning to study.

As artificial intelligence grows more capable of performing tasks once considered exclusively human, many people wonder which skills will remain valuable in the future. However, most researchers argue that AI still struggles with tasks requiring genuine empathy, ethical judgment, and creative problem-solving in unfamiliar situations. Similarly, AI can generate countless design variations, yet it lacks the lived experience that allows humans to judge which idea truly resonates with people. For this reason, educators increasingly emphasize skills such as collaboration, critical thinking, and emotional intelligence, arguing that ___________.

Remote work has moved from a rare privilege to a common practice for millions of employees worldwide. Supporters argue that remote work increases productivity, since employees avoid long commutes and distracting office environments. It also allows companies to hire talented people regardless of where they live, widening the pool of candidates. Critics, however, worry that remote work weakens teamwork and makes it harder for new employees to learn from experienced colleagues. Without regular face-to-face interaction, some workers feel isolated and struggle to build strong professional relationships. For these reasons, many experts suggest that the future of work will likely be ___________, combining flexibility with occasional in-person collaboration.

Athletes preparing for major endurance events sometimes train for weeks at high altitude, where the air contains less oxygen than at sea level. In this thin air, the body responds by producing more red blood cells, which carry oxygen more efficiently through the bloodstream to working muscles. When these athletes return to sea level, their blood retains this elevated capacity for a limited period, potentially translating into improved endurance performance. However, the benefits of altitude training are far from guaranteed, since individual athletes respond quite differently to the same conditions, and some experience excessive fatigue that undermines the very training they hoped to complete. Many elite programs therefore follow a strategy known as live high, train low, in which _______________.

The gig economy, in which people take on short-term or freelance jobs instead of full-time positions, has grown rapidly over the past decade. This model offers clear advantages: workers can choose when and how much they work, and businesses can hire help only when they actually need it. For many young people entering the job market, gig work provides valuable flexibility that traditional employment rarely allows. However, gig workers often ___________, which full-time employees typically receive. Because their income can fluctuate sharply from month to month, many gig workers struggle to plan their finances confidently.

Parkinson's Law appears frequently in everyday workplaces, often without employees even realizing it. (A) As a result, the meeting naturally stretches to fill the entire hour, even though very little new information is actually discussed. (B) This situation illustrates the law's central claim that the amount of time allotted for a task directly shapes how long the task actually takes. (C) Consider a manager who schedules an hour-long meeting to discuss a minor issue that could realistically be resolved in only a few minutes.

주어진 문장: In other words, working longer hours does not necessarily lead to better results if that time is spent in a low-energy state. For decades, productivity advice has focused almost entirely on managing time efficiently, yet many experts now argue this approach overlooks something important. ( ① ) This alternative approach, known as energy management, suggests that controlling personal energy matters more than controlling the clock. ( ② ) Unlike time, which flows at a constant rate, human energy naturally rises and falls in cycles shaped by sleep, food, and mental fatigue. ( ③ ) A person who tackles difficult tasks during a low-energy period, for instance, may need two hours to finish what takes thirty minutes at peak energy. ( ④ ) Similarly, someone who forces themselves to keep working without rest often produces careless mistakes that require additional time to correct later. ( ⑤ ) Advocates of energy management recommend identifying one's peak hours and reserving them for demanding work, while saving low-energy periods for routine tasks.

One of the clearest examples of this involves a specific protein that stimulates the growth of new brain cells. Exercise does far more than strengthen muscles and the heart; it also produces measurable changes within the brain itself. ( ① ) 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. ( ② ) Studies comparing physically active students to sedentary peers have repeatedly found that the active group performs better on tests of attention and problem-solving, even when the exercise session ends well before the test begins. ( ③ ) 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. ( ④ ) Interestingly, aerobic activities such as running or swimming appear to produce more pronounced cognitive benefits than purely strength-based training. ( ⑤ )
