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.

Adaptive learning apps promise something no traditional classroom can easily offer: a lesson plan that adjusts itself to each individual student in real time. As a student answers practice questions, the app ① tracks which concepts are mastered and which remain shaky, then quietly reshuffles the next set of problems to target the weaker areas. Early studies suggest that this ② personalized pacing can help struggling students catch up faster than a one-size-fits-all worksheet ever could. However, critics ③ caution that an app cannot replace the encouragement, humor, and flexibility a human teacher brings to a lesson, especially when a student is frustrated rather than simply behind. There is also a subtler concern: students who grow used to ④ instant, algorithm-generated feedback may struggle later with the slower, more ambiguous kind of feedback that real-world tasks and mentors typically provide, which could ⑤ strengthen their ability to handle uncertainty outside the app.

Psychologists have long studied a mechanism called the variable reward schedule, in which rewards arrive ①predictably rather than after every single action. Slot machines famously exploit this principle, and social media notifications operate on strikingly similar logic. When someone posts a photo, they cannot predict exactly when likes will appear, nor how many they will eventually receive. This uncertainty triggers a small burst of dopamine each time the phone is checked, regardless of whether the result is ②disappointing or thrilling. Consequently, users often refresh their feeds ③compulsively, hoping the next check will finally bring a satisfying reward. What makes this troubling is that technology companies ④deliberately designed notification systems using insights borrowed from gambling research, rather than stumbling upon them by accident. Such practices raise serious ethical questions about ⑤manipulating users' brains for profit.

Researchers who study teenagers have found a strong link between how well students sleep and how well they perform in school. Students who sleep fewer than seven hours a night tend to score lower on tests of memory and attention than those who sleep eight or nine hours, even when the two groups study for the same number of hours. One explanation is that sleep plays an active role in learning: during certain stages of sleep, the brain replays and strengthens information encountered during the day, _______________. When sleep is cut short, this consolidation process is interrupted before it can finish, so material that seemed well understood the night before often feels unfamiliar the next morning. For this reason, some schools have begun rethinking early start times, reasoning that an extra hour of sleep might do more for test scores than an extra hour of studying ever could.

Mira had lived in a coastal village since birth, watching the tide creep closer to her family's doorstep every year. When the sea finally swallowed the rice paddies that had fed her village for generations, her parents decided that staying was no longer possible. Together with many neighbors, they packed what little they could carry and moved inland, becoming what experts now call climate migrants, _______________. This term, rarely used a decade ago, has become increasingly common as extreme weather displaces communities worldwide. Mira missed her old house terribly, yet she slowly began to build a new life in the crowded city, learning to adapt just as her ancestors once had. International organizations, however, still struggle to agree on how to protect people like her, since climate migrants are not officially recognized as refugees under current law.

Job seekers often assume that their closest friends will be the most helpful source of career advice. (A) In fact, studies show that a surprising number of job offers come through acquaintances met only briefly at conferences or previous workplaces. (B) However, close friends usually work in the same field or social circle, so their knowledge of new openings tends to overlap with what the job seeker already knows. (C) This is because such acquaintances belong to different professional circles, giving them access to information that never reaches close friends.

주어진 문장: This is why productivity coaches often recommend starting with just one or two blocks per day rather than filling the entire schedule at once. Time blocking is a time-management technique in which a person divides the day into fixed blocks. Each block is then assigned to a single task. ( ① ) Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. ( ② ) This approach lowers the mental effort of deciding what to do next, since the schedule already provides the answer. ( ③ ) It also limits multitasking, because each block is reserved for only one activity at a time. ( ④ ) For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing, while another student may reserve an evening block solely for vocabulary review. Because each block has a clear boundary, unfinished work is less likely to quietly spread into the next task. Many people who adopt time blocking feel more organized throughout the day. ( ⑤ )

주어진 문장: Every choice, from filters to captions, is carefully calculated to create a favorable impression on viewers. 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. ( ① ) This idea applies vividly to social media, where users select flattering photos and delete posts that might damage their reputation. ( ② ) Such careful curation allows people to present an idealized version of themselves that emphasizes achievements while hiding struggles or ordinary moments. ( ③ ) However, when this performance becomes constant, a troubling gap can form between one's authentic self and the polished character displayed online. ( ④ ) Maintaining that gap requires considerable emotional energy, and studies suggest it often leads to anxiety and exhaustion. ( ⑤ ) Furthermore, comparing one's own carefully staged life to others' equally staged posts can distort what people believe is normal. Therefore, individuals should recognize that some self-presentation online is inevitable, but they must also protect space where imperfection is allowed to remain visible.

Treating a wellness app as a substitute for medical expertise, they warn, can be just as risky as ignoring a warning altogether. A growing number of health apps now track steps, sleep, and heart rate throughout the day, quietly building a detailed picture of a user's physical condition without requiring a single visit to a doctor's office. ( ① ) By comparing this stream of data against patterns drawn from millions of other users, the app's algorithm can flag early warning signs, such as an irregular heartbeat, long before the person experiencing it would have noticed anything unusual on their own. ( ② ) For people living far from specialists or unable to afford frequent checkups, this kind of constant monitoring can feel like a genuine safety net. ( ③ ) Doctors caution, however, that these apps are designed to detect patterns, not to diagnose illness. ( ④ ) A worried user should always confirm any alarming reading with a professional rather than trusting an app's suggestion alone. ( ⑤ )

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 )
