Climate scientists frequently warn about tipping points, thresholds beyond which a small additional change ①triggers a large, often irreversible shift in the climate system. Unlike gradual warming, which unfolds steadily over decades, crossing a tipping point can produce dramatic consequences within a short period. For instance, as Arctic ice melts, it exposes darker ocean water that ②absorb more sunlight than reflective ice, accelerating further melting in a self-reinforcing cycle. Similarly, scientists worry that a major ocean current, which currently ③redistributes heat across the planet, could slow dramatically if enough freshwater from melting glaciers dilutes the surrounding seawater. Once such thresholds are crossed, ④restoring the original balance may become nearly impossible, even if emissions are later reduced. Therefore, researchers argue that preventing these transitions ⑤matters more than merely slowing average temperature increases.

For most of last year, Junho refreshed his social media feed constantly, ①terrified of missing a party, a trending meme, or gossip among his friends. This restless anxiety, often called FOMO, or the fear of missing out, left him ②relaxed and strangely unsatisfied even after hours of scrolling. One weekend, his phone battery died during a hiking trip, and, to his surprise, he actually ③enjoyed the quiet afternoon without notifications interrupting his thoughts. Curious about this ④unexpected calm, Junho began deleting social apps for a few hours each day. This shift in attitude reflects what psychologists now call JOMO, a mindset that treats disconnection as ⑤freedom rather than loss.

Modern sports wearables, from wrist-worn fitness trackers to smart insoles embedded in running shoes, continuously collect data that would once have required a laboratory to measure. Heart rate, sleep quality, running cadence, and even subtle changes in gait can now be ① monitored during ordinary daily activity rather than only in a controlled clinical setting. Coaches use this constant stream of information to detect early warning signs of overtraining, sometimes noticing a decline in performance ② after the athlete consciously feels tired. However, the flood of data has created a new challenge: distinguishing a meaningful pattern from ordinary daily fluctuation requires expertise that many amateur athletes simply ③ do not have. Some researchers worry that casual users may misinterpret a single unusual reading as a serious problem, leading to ④ needless anxiety rather than useful insight. For this reason, most experts recommend treating wearable data as a general trend to observe over time, not as a precise ⑤ diagnostic tool.

Sociologists use the term homophily to describe the tendency of people to form connections with others who share ①different backgrounds, opinions, or interests. This principle explains why classmates from the same major often become close friends, while coworkers with shared hobbies naturally gravitate toward one another. Because similarity reduces the effort required to understand another person's perspective, relationships built on shared traits tend to feel ②comfortable and require less negotiation. However, this same comfort can ③narrow the range of viewpoints someone encounters, since surrounding oneself with similar people limits exposure to different ideas. Social media platforms intensify this pattern through recommendation algorithms that suggest new friends based on shared interests or similar browsing history. As a result, users often find their online circles becoming increasingly ④homogeneous, filled with people who think and behave much like themselves. Recognizing this tendency allows individuals to make ⑤deliberate efforts to broaden their social networks.

Summer is the best time to enjoy swimming pools, rivers, and beaches with family and friends. However, water activities can be dangerous without proper preparation. That is why experts stress one point above all: ___________. First, always swim in areas supervised by a lifeguard, and never swim alone even if you are a strong swimmer. Second, check the weather and water conditions before entering the water, since strong currents and sudden storms make swimming risky. Third, wear a life jacket in open water such as a river or the sea, especially if you are a child or a beginner.

Automation is transforming labor markets more quickly than economists predicted only a decade ago. Factories once staffed by hundreds of workers now rely on robotic arms that assemble products with remarkable precision, and warehouses use automated systems to sort and deliver packages within a few hours. This shift does not simply eliminate jobs; it also creates roles that never existed before. Technicians who maintain robotic equipment are now in high demand, and engineers who design efficient automated systems are highly valued. Companies that invested early in automation often report ___________, since machines handle repetitive tasks while employees focus on creative problem-solving. This transition, however, also raises concerns about workers whose skills quickly become outdated. Policymakers argue that retraining programs are essential to help displaced workers move into emerging fields.

During sleep, the brain does not simply rest; it actively reorganizes the day's experiences into lasting memories through a process called consolidation. (A) Sleep researchers have demonstrated this effect experimentally: participants who slept after learning a list of word pairs recalled more items the next day than participants who remained awake instead. Crucially, the benefit was not limited to simple recall; sleep also seemed to help participants extract general patterns from the material, suggesting that consolidation involves more than passive storage. (B) Newly formed memories are initially fragile and stored primarily in a brain region called the hippocampus, which has limited long-term capacity. (C) While a person sleeps, particularly during the deep stages of non-REM sleep, neural activity replays these fresh memory traces in rapid, compressed sequences, gradually transferring the information to the cortex for more durable, long-term storage. This replay strengthens the connections between neurons that encoded the original experience, making the memory more resistant to interference from unrelated events the following day.

Robert Merton refined this framework by distinguishing manifest functions, the intended and openly recognized consequences of a social practice, from latent functions, unintended consequences that nonetheless help sustain the system, such as schools serving not only to educate but also to provide childcare that allows parents to work. Structural functionalism approaches society as a complex system of interdependent parts, each contributing to the overall stability and smooth operation of the whole, much as organs contribute to the survival of a biological body. ( ① ) Sociologist Talcott Parsons argued that institutions such as the family, education, religion, and government each perform necessary functions, socializing new members and transmitting values. ( ② ) Removing or weakening any one institution, in his view, threatens the equilibrium of the entire system. ( ③ ) Critics have long charged that functionalism, by emphasizing stability and equilibrium, struggles to explain social conflict and rapid change. ( ④ ) It tends to interpret persistent inequality as somehow functional for society rather than as a problem requiring correction. ( ⑤ )

주어진 문장: Unlike a rigid vegan diet, this approach does not require anyone to give up their favorite dishes completely. 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. ( ① ) 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. ( ② ) Cattle, in particular, release large amounts of methane, a gas far more powerful than carbon dioxide at trapping heat in the atmosphere. ( ③ ) 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. ( ④ ) Nutritionists also emphasize that flexitarian eating is easier to maintain than full vegetarianism, because it allows flexibility rather than demanding absolute discipline. ( ⑤ ) Therefore, many environmental groups now promote flexitarianism as a realistic first step, believing that gradual change, rather than sudden restriction, is more likely to spread widely across society.

주어진 문장: This gap between image and reality is precisely what makes the practice so misleading. Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims turn out to be misleading. ( ① ) This practice, known as greenwashing, occurs when a business spends more effort marketing its products as eco-friendly than actually reducing environmental harm. ( ② ) A company might launch a recycled-packaging line while continuing to pollute rivers through its main factories, creating a false impression of genuine change. ( ③ ) Such tactics deceive well-intentioned consumers who wish to shop responsibly but lack the tools to verify corporate claims. ( ④ ) In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, allowing outsiders to check their progress. ( ⑤ ) Therefore, shoppers should look beyond vague labels like green or natural and instead search for recognized certifications, transparent reports, and measurable targets. Without such scrutiny, greenwashing will keep flourishing, undermining public trust and slowing the broader shift toward an economy that truly protects the planet.
