Sociologist Erving Goffman argued that people constantly perform for others, much like actors ①managing their image on a stage, a concept known as impression management. This idea applies vividly to social media, where users select flattering photos and delete posts ②that might damage their reputation. Such careful curation allows people ③to present an idealized version of themselves that emphasizes achievements while hiding struggles or ordinary moments. However, when this performance becomes constant, a troubling gap can form between one's authentic self and the polished character ④displaying online. Maintaining that gap requires considerable emotional energy, and studies suggest it often leads to anxiety and exhaustion. 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 ⑤is allowed to remain visible.

Secondhand trading platforms, once considered a niche market for used goods, have grown into a mainstream part of consumer culture. Rising prices for new products, combined with growing awareness of environmental waste, have encouraged many shoppers to consider used items before purchasing something brand new. These platforms allow individuals to sell clothing, electronics, and furniture directly to other consumers, cutting out traditional retail markups entirely. For younger buyers especially, purchasing secondhand items has become associated with resourcefulness rather than financial necessity, ①change how such purchases are perceived socially. To ②address this problem, many platforms now ③offer buyer protection programs and detailed rating systems for sellers. As trust in these systems continues to grow, secondhand trading is ④expected to ⑤expand even further in the coming years.

Instead of typing keywords into a search bar, a growing number of people now simply upload a photo and let an algorithm ①figure out what it contains. This process, known as reverse image search, compares the visual patterns in a picture against a massive database, ②identifying everything from a landmark in the background to the exact model of a pair of sneakers. Shoppers use it to find where an item seen on the street can ③be purchased, while students use it to identify plants, insects, or historical artworks in seconds. The system works by breaking an image down into countless small features, then ④matches that pattern against millions of stored examples. It is not flawless, however; a blurry photo, an unusual camera angle, or an object partly hidden behind another can easily ⑤confuse the algorithm.

Sociologist Mark Granovetter introduced an idea that seems ①contradictory at first glance, known as the strength of weak ties. According to this theory, people who see each other only ②occasionally, called weak ties, often provide more valuable information than close friends or family members, who are considered strong ties. This happens because strong ties tend to share the same social circles and, therefore, already possess ③similar knowledge. Weak ties, in contrast, move within different networks, which allows them to introduce ideas or opportunities that would otherwise remain unknown. For example, a former classmate rarely contacted might mention a job opening unavailable through one's immediate circle. Social media platforms have made maintaining such connections remarkably ④harder, letting users keep hundreds of loose acquaintances active without frequent face-to-face meetings. Consequently, these platforms function as efficient channels through which weak ties continue delivering ⑤fresh opportunities that close relationships simply cannot offer.

Smart speakers have quietly become a fixture in many households, responding to spoken requests for weather updates, music, or kitchen timers. Behind this ①simple exchange lies a complex process: the device converts sound waves into text, interprets the meaning using language models, and then generates a spoken reply, all within a second or two. Because these assistants ②improve by learning from millions of interactions, they gradually become better at recognizing regional accents and casual phrasing that once confused them. Still, the technology remains far from ③perfect. Background noise, overlapping voices, or an unusual sentence structure can cause the assistant to misunderstand a simple request, sometimes with ④flawless results. Engineers continue to refine these systems, but many admit that truly natural conversation remains one of the hardest ⑤goals in the entire field of artificial intelligence.

Every day, email providers quietly block billions of unwanted messages before they ever reach a user's inbox, a task that would be impossible without an AI filtering system running constantly in the background. (A) This creates a constant back-and-forth, since spammers study which messages get blocked and then adjust their wording to slip through again. (B) The filter examines each incoming message for suspicious patterns, including certain keywords, unusual sender addresses, and formatting tricks that scammers commonly rely on to slip past detection. (C) What makes the system effective is that it keeps learning after launch, since a user's action of marking or rescuing a message becomes new training data.

주어진 문장: In other words, those who did the least to cause the problem often end up paying the highest price for it. When people discuss climate change, they often focus only on rising temperatures or melting ice, treating it as a purely scientific issue. ( ① ) However, the concept of climate justice reminds us that the causes and consequences of climate change are distributed unevenly across the globe. ( ② ) Wealthy, industrialized nations have historically released the largest share of greenhouse gases while building their economies, yet developing nations, which contributed comparatively little, frequently suffer the most severe droughts and floods. ( ③ ) This gap between responsibility and suffering raises a serious ethical question that science alone cannot answer. ( ④ ) For example, a farming community in a low-income country may lose its entire harvest to an unusual flood, even though its members have never owned a car or flown on a plane. ( ⑤ ) Therefore, tackling climate change requires more than new technology; it demands fair policies supporting the very communities least responsible for causing the crisis.

주어진 문장: This is precisely why scientists treat these thresholds with such urgency, rather than viewing them as distant, abstract possibilities. Climate scientists frequently warn about tipping points, thresholds beyond which a small additional change triggers a large, often irreversible shift in the climate system. ( ① ) Unlike gradual warming, which unfolds steadily over decades, crossing a tipping point can produce dramatic consequences within a short period. ( ② ) For instance, as Arctic ice melts, it exposes darker ocean water that absorbs more sunlight than reflective ice, accelerating further melting in a self-reinforcing cycle. ( ③ ) Similarly, scientists worry that a major ocean current, which currently redistributes heat across the planet, could slow dramatically if enough freshwater from melting glaciers dilutes the surrounding seawater. ( ④ ) Once such thresholds are crossed, restoring the original balance may become nearly impossible, even if emissions are later reduced. ( ⑤ ) Therefore, researchers argue that preventing these transitions matters more than merely slowing average temperature increases. Identifying how close each system stands to its threshold remains one of the most urgent challenges in climate research.

주어진 문장: Unlike traditional employees, these workers are typically classified as independent contractors. 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. Digital platforms now connect customers directly with drivers, designers, writers, and countless other independent workers within minutes. ( ① ) 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. ( ② ) For many young people entering the job market, gig work provides valuable flexibility that traditional employment rarely allows. ( ③ ) However, gig workers often lack benefits such as health insurance, paid leave, and retirement savings, which full-time employees typically receive. ( ④ ) Because their income can fluctuate sharply from month to month, many gig workers struggle to plan their finances confidently. ( ⑤ ) As this sector continues to expand, governments face growing pressure to design policies that protect independent workers.

주어진 문장: Yet not every worker benefits equally from these changes. Automation is transforming labor markets more quickly than economists predicted a decade ago. ( ① ) Factories once staffed by hundreds of workers now rely on robotic arms that assemble products with remarkable precision. ( ② ) This shift does not simply eliminate jobs; it also creates roles that never existed before, such as technicians who maintain robotic equipment. ( ③ ) Companies that invested early in automation often report steady increases in productivity, since machines handle repetitive tasks while employees focus on creative problem-solving. ( ④ ) Policymakers argue that retraining programs are essential to help displaced workers move into emerging fields. ( ⑤ ) Without such support, the benefits of automation may not be shared fairly across society.
